NetStream Configuration Commands

NetStream Configuration Commands

NOTE:

The NetStream function conforms to IETF RFC3954. For security risks, see IETF RFC3954. This function involves analyzing the communications information of terminal customers. Before enabling the function, ensure that it is performed within the boundaries permitted by applicable laws and regulations. Effective measures must be taken to ensure that information is securely protected.

CE6810LI only supports exported packets carrying Layer 2 flow statistics.

Only CE8860EI, CE8850EI, CE7855EI, CE7850EI, CE6880EI, CE6870EI, CE6860EI, CE6856HI, CE6855HI, CE6851HI, CE6850HI, and CE6850U-HI support VXLAN flexible flow statistics.

The CE6880EI does not support NetStream Top Talkers.

assign netstream management-plane export rate-limit

Function

The assign netstream management-plane export rate-limit command limits the rate of NetStream packets sent from a switch to the control plane, thereby limiting the rate of NetStream packets sent out by the control plane.

The undo assign netstream management-plane export rate-limit command cancels limitation on the rate of NetStream packets sent from a switch to the control plane.

By default, the rate of NetStream packets sent to the control plane is not limited.

NOTE:

The CE6880EI does not support this command.

Format

assign netstream management-plane export rate-limit rate-limit [ slot slot-id ]

undo assign netstream management-plane export rate-limit rate-limit [ slot slot-id ]

Parameters

Parameter Description Value
rate-limit Specifies the rate of NetStream packets sent from a switch to the control plane. The value is an integer that ranges from 100 to 1500, in pps.
slot slot-id

Specifies the stack ID of the switch where the rate of output NetStream packets is limited.

If this parameter is not specified, the rate of NetStream packets sent from all cards to the control plane is limited.

The value is an integer. You can enter a question mark (?) and select a value from the displayed value range.

Default Level

3: Management level

Usage Guidelines

Usage Scenario

After NetStream is configured on a switch, the switch selects a service interface or management interface to send out NetStream packets according to the route to the NetStream server. If the switch selects the service interface, the NetStream packets generated in NetStream sampling are forwarded out through the service interface, but do not pass the control plane. If the switch selects the management interface, the NetStream packets generated in NetStream sampling are forwarded to the control plane for processing and then sent out through the management interface.

When a network has heavy traffic and the switch sends NetStream packets through the management interface to the NetStream server, a large number of NetStream packets generated by a switch are sent to the control plane to overwhelm the CPU and affect the running of other protocols, or even cause the switch to be out of management. To limit the rate of NetStream packets sent from a switch to the control plane, run the assign netstream management-plane export rate-limit command. After this command is executed, the rate of NetStream packets sent from the control plane is also limited, and the number of NetStream packets sent through the management interface is reduced.

Precautions

If the assign netstream management-plane export rate-limit rate-limit slot slot-id command has been executed to limit the rate of NetStream packets sent from a specified card to the control plane, you cannot run the assign netstream management-plane export rate-limit rate-limit command to limit the rate of NetStream packets sent from all cards to the control plane. If the assign netstream management-plane export rate-limit rate-limit command has been executed to limit the rate of NetStream packets sent from all cards to the control plane, you cannot run the assign netstream management-plane export rate-limit rate-limit slot slot-id command to limit the rate of NetStream packets sent from a specified card to the control plane.

Example

# Set the maximum rate of NetStream packets sent from all cards to the control plane to 1000 pps.

<HUAWEI> system-view
[~HUAWEI] assign netstream management-plane export rate-limit 1000

cache-timeout

Function

enable

Function

The enable command enables the aggregation function in the aggregation view.

The undo enable command disables the aggregation function in the aggregation view.

By default, the aggregation function is disabled.

Format

enable

undo enable

Parameters

None

Views

IPv4 NetStream aggregation view, IPv6 NetStream aggregation view

Default Level

3: Management level

Usage Guidelines

The enable command takes effect only in the NetStream aggregation view. Flow statistics are exported according to the configured aggregation method only after you run the enable command in the aggregation view.

Example

# Enable destination address prefix aggregation.

<HUAWEI> system-view
[~HUAWEI] netstream aggregation ip destination-prefix
[*HUAWEI-netstream-aggregation-dstpre] enable

export version

Function

The export version command configures the version of exported packets carrying aggregation flow statistics.

The undo export version command restores the default setting.

In the following aggregation modes, the default export version of aggregation flow statistics is V8:

  • as
  • as-tos
  • destination-prefix
  • destination-prefix-tos
  • prefix
  • prefix-tos
  • protocol-port
  • protocol-port-tos
  • source-prefix
  • source-prefix-tos

Format

export version { 8 | 9 }

undo export version [ 8 | 9 ]

Parameters

Parameter

Description

Value

8

Sets the version number of exported packets carrying aggregation flow statistics to 8.

-

9

Sets the version number of exported packets carrying aggregation flow statistics to V9.

-

Views

IPv4 NetStream aggregation view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

The NDE exports NetStream flow statistics to the NSC. The version of exported packets must be the same as that configured on the NSC so that the NSC can parse the exported packets.

The format of exported packets in V8 is fixed and is not easy to expand. The format of exported packets in V9 is defined in templates and is easy to combine or expand. The statistics are exported more flexibly.

V9 is supported by most NSCs for its advantages. It is recommended that you set the version of exported packets carrying aggregation flow statistics to V9.

Precaution

When collecting statistics about NetStream aggregation flows, the version of exported packets is the same as that configured on the NMS. If the interface indexes in the exported packets need to be extended to 32 bits, the version must be set to V9.

In the following aggregation methods, the version can be set to V8 or V9:

  • as
  • as-tos
  • destination-prefix
  • destination-prefix-tos
  • prefix
  • prefix-tos
  • protocol-port
  • protocol-port-tos
  • source-prefix
  • source-prefix-tos

In the following aggregation methods, the version must be set to V9 and the export version command is invalid:

  • bgp-nexthop-tos
  • index-tos

Usage Guidelines

Usage Scenario

During exporting of VXLAN flexible flow statistics, you can run the match inner-ip command to configure aggregation keywords in a flexible flow statistics template. The aggregation keywords refer to the destination IP address, destination port number, ToS, protocol type, source IP address, and source port number in the original Ethernet frames encapsulated in VXLAN packets.

Usage Guidelines

Usage Scenario

To specify keywords in a NetStream Top Talkers template to filter traffic, run the match ip command. After you specify the keywords, the device filters traffic based on the specified keywords, collects traffic statistics, sorts the traffic, and displays the statistics and sorting results.

Prerequisites

A NetStream Top Talkers template has been created using the netstream top-talkers ip (system view) command.

Precautions

Running the match ip command once can specify only one keyword. If the command is run multiple times in the same view, traffic is filtered based on multiple keywords.

The keywords tos, dscp, and precedence cannot be configured together in a NetStream Top Talkers template; otherwise, the filtering result may be unexpected. For example, if you specify tos, and then specify dscp, the device filers traffic based on the DSCP field of packets.

You can set the keyword source-port, destination-port, packet-range, or byte-range in any of the following ways:
  • Set both the maximum and minimum values of each keyword. That is, specify that a NetStream Top Talkers template filters the traffic of which the source port number, destination port number, number of packets, or number of bytes ranges from the minimum value to the maximum value.

  • Set only the minimum value of each keyword. That is, specify that a NetStream Top Talkers template filters the traffic of which the source port number, destination port number, number of packets, or number of bytes is equal to or larger than the minimum value.

  • Set only the maximum value of each keyword. That is, specify that a NetStream Top Talkers template filters the traffic of which the source port number, destination port number, number of packets, or number of bytes is equal to or smaller than the maximum value.

Example

# Configure the NetStream Top Talkers template test to filter traffic based on source IP address.

Usage Guidelines

Usage Scenario

NetStream aggregation groups the original flows with the same attributes together. The aggregation flow statistics collection and original flow statistics collection are different. The original flow statistics collection is on the basis of sampled packets, while the aggregation flow statistics collection is on the basis of original flows. Therefore, the aggregation flow statistics collection generates less data.

The aggregation flow statistics collection provides 15 aggregation methods and has the following benefits:

  • If the user concerns about only one attribute of network traffic, the aggregation flow statistics collection is a good choice.
  • The aggregation flow statistics collection reduces the volume of data sent to the NMS, relieving network loads.
  • The aggregation flow statistics collection consumes less resource to process aggregation flows. The NMS obtains flow information by resolving the aggregation flow statistics through the aggregation template.

Prerequisites

Before configuring MPLS-label aggregation, run the netstream mpls-aware ip command to set the sampling mode for MPLS packets to label-and-ip or label-only.

Precautions

When the aggregation mode is set to vlan-id, the switch can aggregate only inbound original flows.

When NetStream aggregation mode is set to as, as-tos, or bgp-nexthop-tos, the exported NetStream packets must contain routing information.

When the exported NetStream packets do not carry routing information and the NetStream aggregation mode is destination-prefix, destination-prefix-tos, prefix, prefix-tos, source-prefix, source-prefix-tos, or source-index-tos, the as, next hop, and BGP next hop fields in the exported NetStream packets have a fixed value of 0.

Follow-up Procedure

Run the enable command in the aggregation view to enable the device to export flow statistics according to the configured aggregation method.

Usage Guidelines

Usage Scenario

Network traffic may burst intermittently, while the memory capacity of the NDE is limited. Earlier flows in the memory need to be exported to release space for the new flows. The process of exporting old flows is called aging. All flows in the NDE memory will be exported to the NSC for analysis.

When the active time (from flow creation time to the current time) of an aggregation flow exceeds the specified active aging time, the flow is exported to the destination.

To quickly detect the status of an active flow, set the active time to a small value; however, this setting increases the frequency at which NetStream packets are sent. To reduce the frequency at which NetStream packets are exported and improve statistics collecting efficiency, set the active time to a large value.

Precaution

If you set multiple aging modes on the device, a flow is aged when it matches any criterion.

3: Management level

Usage Guidelines

Usage Scenario

Network traffic may burst intermittently, while the memory capacity of the NDE is limited. Earlier flows in the memory need to be exported to release space for the new flows. The process of exporting old flows is called aging. All flows in the NDE memory will be exported to the NSC for analysis.

When the inactive time (from the last packet receiving time to the current time) of an IPv6 aggregation flow exceeds the specified inactive aging time, the flow is exported to the destination.

To quickly detect the status of an inactive flow, set the inactive time to a small value; however, this setting increases the frequency at which NetStream packets are sent. To reduce the frequency at which NetStream packets are exported and improve statistics collecting efficiency, set the inactive time to a large value.

Precaution

If you set multiple aging modes on the device, a flow is aged when it matches any criterion.

Example

# Set the inactive aging time of IPv6 aggregation flows to 200 seconds.

Default Level

3: Management level

Usage Guidelines

Usage Scenario

After the 16-bit AS number is set, NetStream exports templates and samples data flows using the 16-bit AS number. After the 32-bit AS number is set, NetStream exports templates and samples data flows using the 32-bit AS number.

The specified AS number format must be the same as that used on the network; otherwise, NetStream cannot sample flows between ASs.

Prerequisites

On a network using the 32-bit AS number format, the NMS must be able to identify the 32-bit AS numbers. Otherwise, the NMS cannot identify inter-AS flows sent from devices.

Example

# Set the 32-bit AS number format for NetStream sampling.

Usage Scenario

After finishing data collection, the NDE sends the collected data to the NSC. This command specifies the destination address of the collected data, that is, the NSC IP address.

Precautions

When you run the netstream export ip host command in the system view, this command configures the destination address for the exported packets carrying IPv4 original flow statistics and IPv4 flexible flow statistics; when you run this command in the aggregation view, this command configures the destination address for the exported packets carrying IPv4 aggregation flows. The exported packets carrying aggregation flow statistics preferentially use the destination address configured in the aggregation view. If the destination address is not configured in the aggregation view, the exported packets carrying aggregation flow statistics use the destination address configured in the system view.

You can configure two destination addresses in the system view or aggregation view to implement NSC backup. To configure a third destination IP address, run the undo netstream export ip host command to delete an existing one first; otherwise, the system displays a message indicating that the maximum number of addresses is exceeded and the configuration fails.

Views

System view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

You can run the ip netstream export index-switch command to set the number of digits in the interface index to 16 or 32.

The number of digits in an interface index contained in exported packets must be the same as the number of digits in an interface index that can be parsed by the NMS. For example, if the NMS can parse the 32-digit interface index, set the number of digits in an interface index contained in exported packets to 32.

Precautions

The number of digits in the interface index can be changed to 32 only when the NMS supports 32-digit interface index. If the number of digits in an interface index contained in exported packets is different from the number of digits in an interface index supported by the NMS, the NMS cannot identify NetStream packets sent by the device.

This command is valid for V9. Before changing 16-digit interface indexes to 32-digit interface indexes, ensure that:

  • The version of exported packets of original flows is V9.
  • The version of exported packets carrying aggregation flow statistics is V9.

When the 32-digit interface index is used, the version of exported packets of original flows cannot be changed from V9 to V5, and the version of exported packets carrying aggregation flow statistics cannot be changed from V9 to V8.

Default Level

3: Management level

Usage Guidelines

Usage Scenario

By default, NetStream packets exported by the device carry routing information. The device collects routing information together with NetStream sampling, and encapsulates routing information into NetStream packets. This will increase the CPU usage of the device. When a network carries heavy traffic or runs many services, the device performance may be degraded.

After the netstream export ip route disable command is executed, the device performance is improved. After NetStream IPv4 is configured on the device, if you do not need the IPv4 routing information, run this command.

Precautions

When NetStream aggregation mode is set to as, as-tos, or bgp-nexthop-tos, the exported NetStream packets must contain routing information.

When the exported NetStream packets do not carry routing information and the NetStream aggregation mode is destination-prefix, destination-prefix-tos, prefix, prefix-tos, source-prefix, source-prefix-tos, or source-index-tos, the as, next hop, and BGP next hop fields in the exported NetStream packets have a fixed value of 0.

Usage Guidelines

Usage Scenario

The NDE exports NetStream flow statistics to the NSC. The version of exported packets must be the same as that configured on the NSC so that the NSC can parse the exported packets.

The format of exported packets in V5 is fixed and is not easy to expand. The format of exported packets in V9 is defined in templates and is easy to combine or expand. The statistics are exported more flexibly.

V9 is supported by most NSCs for its advantages. It is recommended that you set the version of exported packets carrying aggregation flow statistics to V9.

You can set the export version according to the NMS configuration. V9 must be used for the following exported packets:
  • Exported packets carrying IPv4 flexible flow statistics

  • Exported packets carrying BGP next-hop information

  • Exported packets carrying 32-bit interface indexes

Precautions

When the exported packets carry 32-bit interface indexes, the export version cannot be changed from V9 to V5.

The AS option is used according to the actual situation of the AS configured on each device. The AS option affects only the packet statistics result, but does not affect the flows. The AS option is encapsulated in the AS option field carried in the NetStream packets sent to the NMS. The exported packets of V5 do not support BGP next hop information.

When the exported NetStream packets do not carry routing information and the NetStream aggregation mode is destination-prefix, destination-prefix-tos, prefix, prefix-tos, source-prefix, source-prefix-tos, or source-index-tos, the as, next hop, and BGP next hop fields in the exported NetStream packets have a fixed value of 0.

Example

# Configure the NetStream packets exported by the device not to carry IPv6 routing information.

Default Level

3: Management level

Usage Guidelines

Usage Scenario

If the NMS identifies the data source according to the source IP address in NetStream packets, you need to specify the source IP address for NetStream packets.

Precaution

If the source IP address is also configured in the system view, NetStream prefers the source IP address configured in the IPv6 aggregation view. If no source address is specified in an aggregation method, the source address configured in the system view is used.

If the source IP address is not specified, packets are not exported. The source address of the exported packets carrying IPv6 aggregation flow statistics can be an IPv4 or IPv6 address. There must be a reachable route between the source IP address and destination IP address (NSC address). Two source IP addresses can be specified: one IPv4 address and one IPv6 address.

Example

# In the system view, set the source address for the exported packets carrying IPv6 flow statistics to 10.1.1.1.

<HUAWEI> system-view
[~HUAWEI] netstream export ipv6 source 10.1.1.1

The value is an integer that ranges from 1 to 3600, in minutes. The default value is 1.

Views

System view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

When the export version for IPv6 original flow statistics and IPv6 flexible flow statistics is set to V9, the template must be exported to the NDA. This command sets the interval for refreshing the V9 template.

If network traffic is heavy, the template refresh interval should be set to a small value; however, this will generate more traffic on the network. You need to set a proper template refresh interval according to network situation. The default refresh interval is recommended if you do not have special requirement.

Precaution

If the default template update interval (30 minutes) is used in V200R001C00 or an earlier version, the interval is automatically changed to 1 minute after the version is upgraded to V200R002C50 or later.

If the default template update interval (1 minute) is used in V200R002C50 or a later version, the interval is automatically changed to 30 minutes after the version is downgraded to V200R001C00 or an earlier version.

Example

# Set the template refresh interval to 50 minutes.

Usage Guidelines

Usage Scenario

On an MPLS network, MPLS labels carry important information that users are concerned about. By default, an NDE samples MPLS packets without labels. You can configure the NDE to sample MPLS labels if necessary.

Precaution

When the MPLS packet sampling method is set to ip-only, you cannot enable MPLS-label aggregation using the netstream aggregation ip command.

Example

# Configure the device to sample only MPLS labels.

netstream sampler

Function

The netstream sampler command configures packet sampling on interfaces.

The undo netstream sampler command restores the default setting.

By default, packet sampling is not configured on interfaces.

Format

netstream sampler random-packets packet-interval { inbound | outbound }

undo netstream sampler [ random-packets packet-interval ] { inbound | outbound }

Parameters

Parameter Description Value
random-packets packet-interval Indicates the number of packets between two sampled packets in the packet-based random sampling. Packet-based random sampling indicates that a packet is sampled every packet-interval packets.

The value is an integer that ranges from 1 to 65535. For details on how to calculate the NetStream sampling rate, see Calculation of the NetStream Sampling Rate.

NOTE:

The recommended NetStream sampling rate is a power of 2. If the calculated value is not a power of 2, the NetStream sampling rate should be greater than the calculated value and a power of 2. For example, if the calculated value is 1020, the recommended NetStream sampling rate is 1024.

inbound Samples incoming traffic on an interface. -
outbound Samples outgoing traffic on an interface. -

Views

System view, Interface view, port group view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

After the NetStream function is enabled on an interface, the system stores the NetStream information in the corresponded interface information table. If every packet passing an interface is captured and counted, forwarding performance on the interface will deteriorate, especially on the interface with a high forwarding rate. To understand interface traffic attributes without compromising forwarding performance, configure packet sampling on the interface. A high sampling rate can significantly reduce impact of NetStream on device performance.

Precautions

  • The packet sampling function configured in the system view takes effect on all interfaces on the device. If the function is configured in both the interface view and system view, the configuration in the interface view has priority.

  • The CE6870EI switches support NetStream sampling rate set in the Layer 3 sub-interface view. If NetStream sampling is configured on the main interface and its Layer 3 sub-interface view, the configuration in the sub-interface view takes effect.
  • Other series switches do not support NetStream sampling rate set in the Layer 3 or Layer 2 sub-interface view. To configure NetStream on Layer 3 or Layer 2 sub-interfaces, the device samples traffic on Layer 3 or Layer 2 sub-interfaces using the NetStream sampling rate configured on the main interface or globally.
  • If you run the netstream sampler command multiple times in the same view, only the latest configuration takes effect.

  • The device sends sampled packets to the CPU for processing when the NetStream sampling mode is set to non-enhanced mode. When the CPU usage of the device exceeds 65%, the device decreases the CAR value of sampled packets sent to the CPU to 1000 pps. As a result, sampled packets to be sent to the CPU are discarded, decreasing the NetStream sampling rate. When the CPU usage falls below 65%, the device increases the CAR value of sampled packets by 500 pps every 20 seconds until the CAR value is restored to the original setting.

Example

# Configure packet-based random sampling on an interface in the inbound direction and set the sampling rate to 8192.

netstream sampler inbound resource snoop

Function

The netstream sampler inbound resource snoop command configures inbound NetStream sampling to use snoop resources.

The undo netstream sampler inbound resource snoop command restores the default configuration.

By default, inbound NetStream sampling uses mirroring resources.

NOTE:

Only the CE6870EI supports this command.

Format

netstream sampler inbound resource snoop

undo netstream sampler inbound resource snoop

Parameters

None

Views

System view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

By default, NetStream sampling uses mirroring resources. When the default configuration is retained, NetStream and port mirroring cannot be configured on the same interface. If you want to use NetStream to collect traffic statistics for accounting and port mirroring to monitor network and locate faults, you need to configure both NetStream and port mirroring on the interface connected to the Internet. In this situation, run the netstream sampler inbound resource snoop command to configure inbound NetStream sampling to use snoop resources. After this command is executed, sampled packets are directly copied to the CPU, but not mirrored; therefore, you can configure port mirroring and inbound NetStream on the same interface.

Pre-configuration Tasks

If the netstream sampler random-packets packet-interval inbound command has been executed in an interface view to configure inbound NetStream sampling, run the undo netstream sampler [ random-packets packet-interval ] inbound command in the interface view to disable the inbound NetStream sampling, and then run the netstream sampler inbound resource snoop command.

If NetStream and port mirroring have been configured on an interface before you run the undo netstream sampler inbound resource snoop command, disable NetStream or port mirroring on the interface, and then run the undo netstream sampler inbound resource snoop command.

Precautions

Snooping resources can only be applied to the inbound direction of an interface.

NetStream sampling using snoop resources conflicts with inbound NetStream sampling configured in an interface view. That is, if NetStream sampling is configured to use snoop resources, you can only configure inbound NetStream sampling in the system view.

Example

# Configure NetStream sampling to use snoop resources.

Default Level

3: Management level

Usage Guidelines

Usage Scenario

Network traffic may burst intermittently, while the memory capacity of the NDE is limited. Earlier flows in the memory need to be exported to release space for the new flows. The process of exporting old flows is called aging. All flows in the NDE memory will be exported to the NSC for analysis.

When the active aging time (from flow creation time to the current time) of a flow exceeds the specified active aging time, the flow is exported to the destination.

To quickly detect the status of an active flow, set the active time to a small value; however, this setting increases the frequency at which NetStream packets are sent. To reduce the frequency at which NetStream packets are exported and improve statistics collecting efficiency, set the active aging time to a large value.

Precaution

If you set multiple aging modes on the device, a flow is aged when it matches any criterion.

After a NetStream Top Talkers template is configured, run the netstream top-talkers ip command in the interface view to apply the template to an interface; otherwise, the NetStream Top Talkers function cannot be implemented. You can configure the NetStream Top Talkers template to collect statistics on and sort incoming or outgoing traffic on an interface.

Prerequisites

A NetStream Top Talkers template has been created using the netstream top-talkers talker-name ip command in the system view. Before applying a NetStream Top Talkers template to an interface, set the number of Top Talkers that can be recorded in the NetStream Top Talkers template, Top Talker sorting order, and statistics collection period; otherwise, the template cannot take effect on the interface. To set the preceding parameters, run the top number, sort-by, and cache-timeout commands.

Precautions

A maximum of two NetStream Top Talkers templates can be applied to one interface, which are used to collect and sort incoming and outgoing traffic separately.

Only the CE6870EI switches apply the NetStream Top Talkers template in the Layer 3 sub-interface view.

Usage Guidelines

Usage Scenario

After the NetStream Top Talkers function is configured, you can run this command to start the NetStream Top Talkers function to collect statistics on and sort traffic.

Precautions

The NetStream Top Talkers function can be immediately started only when the NetStream Top Talkers template is applied to an interface.

When the NetStream Top Talkers function has been started on an interface, the NetStream Top Talkers template applied to this interface can also be applied to another interface. In this situation, traffic statistics on the later interface can only be collected in remaining time.

If you modify the NetStream Top Talkers template while the NetStream Top Talkers function is running, the NetStream Top Talkers function becomes invalid, collected traffic statistics are deleted, and traffic is not sorted in order. To restart the NetStream Top Talkers function, you can run this command again or configure the function to restart on schedule.

If you restart the NetStream Top Talkers function while the NetStream Top Talkers function is running, collected traffic statistics are deleted, traffic is not sorted in order, and the NetStream Top Talkers function restarts.

Usage Guidelines

Usage Scenario

To start the NetStream Top Talkers function on schedule, run this command.

Precautions

The time when the NetStream Top Talkers function starts must be later than the system time; otherwise, the NetStream Top Talkers function cannot be started.

The NetStream Top Talkers function can be started at the specified time only when the NetStream Top Talkers template is applied to an interface.

When the NetStream Top Talkers function has been started on an interface, the NetStream Top Talkers template applied to this interface can also be applied to another interface. In this situation, traffic statistics on the later interface can only be collected in remaining time.

If you run the netstream top-talkers ip starting command after the starting time time date command, the NetStream Top Talkers function is started immediately. When the specified time is reached, collected traffic statistics are deleted, traffic is not sorted in order, and this function is restarted.

If you modify the NetStream Top Talkers template while the NetStream Top Talkers function is running, the NetStream Top Talkers function becomes invalid, collected traffic statistics are deleted, and traffic is not sorted in order.

Example

# Configure the NetStream Top Talkers template test to start traffic statistics collection at 2014-11-06 16:16:16.

<HUAWEI> system-view
[~HUAWEI] netstream top-talkers test ip
[*HUAWEI-netstream-top-talkers-test] starting time 16:16:16 2014-11-06

template timeout-rate

Function

The template timeout-rate command sets the interval at which the template for exporting aggregation flow statistics in V9 format is refreshed.

The undo template timeout-rate command restores the default setting.

By default, the template is refreshed every 1 minute.

Format

template timeout-rate timeout-interval

undo template timeout-rate [ timeout-interval ]

Parameters

Parameter Description Value
timeout-interval

Specifies the interval for refreshing the V9 template.

The value is an integer that ranges from 1 to 3600, in minutes. The default value is 1.

Views

IPv4 NetStream aggregation view, IPv6 NetStream aggregation view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

When the export version for aggregation flow statistics is set to V9, the template must be exported to the NDA. This command sets the interval for refreshing the V9 template.

If network traffic is heavy, the template refresh interval should be set to a small value; however, this will generate more traffic on the network. You need to set a proper template refresh interval according to network situation. The default refresh interval is recommended if you do not have special requirement.

Precaution

If the default template update interval (30 minutes) is used in V200R001C00 or an earlier version, the interval is automatically changed to 1 minute after the version is upgraded to V200R002C50 or later.

If the default template update interval (1 minute) is used in V200R002C50 or a later version, the interval is automatically changed to 30 minutes after the version is downgraded to V200R001C00 or an earlier version.

Example

# Set the interval at which the V9 template for IPv4 aggregation flow statistics to 60 minutes.

<HUAWEI> system-view
[~HUAWEI] netstream aggregation ip source-prefix
[*HUAWEI-netstream-aggregation-srcpre] template timeout-rate 60

# Set the interval at which the V9 template for IPv6 aggregation flow statistics to 50 minutes.

<HUAWEI> system-view
[~HUAWEI] netstream aggregation ipv6 source-prefix
[*HUAWEI-netstream-aggregation-ipv6-srcpre] template timeout-rate 50

top number

Function

The top number command sets the number of Top Talkers that can be recorded in a NetStream Top Talkers template.

The undo top number command deletes the number of Top Talkers that can be recorded in the NetStream Top Talkers template.

By default, the number of Top Talkers that can be recorded in a NetStream Top Talkers template is not set.

Format

top number number

undo top number [ number ]

Parameters

Parameter Description Value
number Indicates the number of Top Talkers that can be recorded in a NetStream Top Talkers template. The value is an integer that ranges from 1 to 200.

Views

NetStream Top Talkers template view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

To specify the number of Top Talkers that can be recorded in a NetStream Top Talkers template, run this command.

Precautions

A maximum of 200 Top Talkers can be recorded in a NetStream Top Talkers template. You are advised to set the value to 200 so that sufficient Top Talkers can be recorded in a NetStream Top Talkers template. For example, when the value is set to N, a NetStream Top Talkers template records only the first N Top Talkers even if more than N traffic lines meet the filter condition. When you run the display netstream top-talkers ip command, only the first N Top Talkers are displayed.

Example

# Configure the NetStream Top Talkers template test to record 100 Top Talkers.

<HUAWEI> system-view
[~HUAWEI] netstream top-talkers test ip 
[*HUAWEI-netstream-top-talkers-test] top number 100
