MEth interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

After a stack in which DAD has been configured splits, the management interface of the switch that fails the DAD competition is shut down. The management interface is not a reserved interface by default. You can log in to this switch only through the console interface instead of the management interface.

If the backup IP address is configured for a stack member switch and the switch fails the DAD competition, enable the management interface and switch the IP address to the backup IP address to prevent conflict with the management IP addresses of other switches. You can then remotely log in to the switch to locate and rectify faults.

Precautions

The configured backup IP address cannot be the same as the IP address of the stack management interface.

The backup IP address does not take effect until a stack splits. You can log in to a stack member using the backup IP address only after the stack splits.

Example

# Set the backup IPv4 address for the switch with the stack member ID 2.

<HUAWEI> system-view
[~HUAWEI] interface meth 0/0/0
[~HUAWEI-MEth0/0/0] dual-active backup ip address 192.168.1.175 24 member 2

dual-active detect enable

Function

The dual-active detect enable command enables dual-active detection (DAD) on the management interface.

The undo dual-active detect enable command disables DAD on the management interface.

By default, DAD is disabled on the management interface.

Format

dual-active detect enable

undo dual-active detect enable

Parameters

None

Views

MEth interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

When a stack splits, two master switches may exist on the network, affecting network operations. The DAD function can prevent this dual-active condition and reduce the impact of a stack split on the network.

When all stack member switches connect to a management network through their management interfaces, DAD can be implemented using the management interfaces. This mode does not occupy additional ports and does not require a DAD relay agent.

Precautions

To implement DAD through management interfaces, ensure that IP addresses are configured for management interfaces.

Example

# Enable the DAD function on the management interface.

<HUAWEI> system-view
[~HUAWEI] interface meth 0/0/0
[~HUAWEI-MEth0/0/0] dual-active detect enable
Warning: If DAD is configured on the management port, the detection takes a long time. You are advised to configure DAD in direct mode. Ensure that no device on the network has the same domain ID and management IP address as those of the local device. Otherwise, a dual-active fault will be detected. Continue? [Y/N]: y

dual-active detect mode direct

Function

The dual-active detect mode direct command configures dual-active detection (DAD) on a service port.

The undo dual-active detect command cancels the configuration.

By default, DAD is disabled on a service port.

Format

dual-active detect mode direct

undo dual-active detect [ mode direct ]

Parameters

None

Views

GE interface view, 10GE interface view, 25GE interface view, 40GE interface view, 100GE interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

You can configure DAD on a service port to ensure that only one switch becomes the master after a stack splits, which enhances stability of the stack.

Configuration Impact

After DAD is configured on a service port, the service port is blocked. Disabling DAD on a service port restores the forwarding function on the service port. If a loop exists on the network, a broadcast storm occurs.

Example

# Configure DAD on 10GE1/0/1.

<HUAWEI> system-view
[~HUAWEI] interface 10ge 1/0/1
[~HUAWEI-10GE1/0/1] dual-active detect mode direct

dual-active detect mode relay

Function

The dual-active detect mode relay command configures dual-active detection (DAD) in relay mode on an Eth-trunk.

The undo dual-active detect command cancels the configuration.

By default, DAD in relay mode is disabled on an Eth-trunk.

Format

dual-active detect mode relay

undo dual-active detect [ mode relay ]

Parameters

None

Views

Default Level

2: Configuration level

Usage Guidelines

You can configure DAD in relay mode on an Eth-trunk to ensure that only one switch becomes the master after a stack splits, which enhances stability of the stack.

dual-active exclude

Function

The dual-active exclude command excludes specified interfaces of a stack from error-down.

The undo dual-active exclude command cancels excluding specified interfaces of a stack from error-down.

By default, only physical member ports are excluded from error-down.

Format

dual-active exclude interface interface-type interface-number1 [ to interface-number2 ]

undo dual-active exclude interface interface-type interface-number1 [ to interface-number2 ]

Parameters

Parameter Description Value
interface interface-type interface-number1 [ to interface-number2 ]
Specifies the type and number of an interface:

  • interface-type specifies the type of the interface.

  • interface-number1 specifies the number of the first interface.

  • interface-number2 specifies the number of the second interface.

The value of interface-number2 must be larger than that of interface-number1.

Views

System view

Default Level

2: Configuration level

Usage Guidelines

After the DAD detects a stack split, member switches compete to determine their active/recovery states. The member switch that fails in the competition shuts down all its service ports to prevent network flapping caused by MAC or IP address flapping. If some ports only transparently transmit packets, they do not affect network operation in a dual-active condition. If you want to retain services on these ports, specify the ports as excluded ports. These ports will not be shut down when a dual-active condition occurs.

Example

# Exclude 10GE1/0/2 and 10GE1/0/3 from shutdown.

<HUAWEI> system-view
[~HUAWEI] dual-active exclude interface 10ge 1/0/2 to 1/0/3

dual-active restore

Function

The dual-active restore command restores all the blocked interfaces of the standby switch that enters the recovery state after its stack splits.

Format

dual-active restore

Parameters

None

Views

System view

Default Level

3: Management level

Usage Guidelines

After the stack in which DAD has been configured splits, the switch that wins the competition retains in Active state and works normally. The other switch that fails in the competition turns to the Recovery state and shuts down all its service ports except the excluded ones. Services on the shutdown ports are interrupted. If the switch in Active state fails or is removed from the network before the stack recovers, you can restore shutdown ports on the switch in Recovery state. Then the switch takes over services on the faulty switch to minimize impact on services.

Example

# Restore all the blocked interfaces of the standby switch that enters the recovery state after its stack splits.

<HUAWEI> system-view
[~HUAWEI] dual-active restore
Warning: This command will restore the device from dual-active conflict state. Continue? [Y/N]: y

dual-active proxy

Function

The dual-active proxy command enables the relay function on a specified interface of a proxy device.

The undo dual-active proxy command disables the relay function on a specified interface of a proxy device.

By default, the relay function is disabled on an interface.

Format

dual-active proxy

undo dual-active proxy

Parameters

None

Views

Eth-Trunk interface view

Default Level

2: Configuration level

Usage Guidelines

In DAD in relay mode, you need to use the dual-active proxy command to configure the relay function on a specified Eth-Trunk interface of a proxy device. Member interfaces of the Eth-Trunk interface forward DAD packets to each other so that member switches can exchange DAD packets.

Example

# Enable the relay function on Eth-Trunk 10 of a proxy device.

<HUAWEI> system-view
[~HUAWEI] interface eth-trunk 10
[~HUAWEI-Eth-Trunk10] dual-active proxy

Views

Management interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

During the upgrade of a stack consisting of two switches using an upgrade tool, you can run the ip address ip-address and mac-address mac-address commands on one switch to set the IP address and MAC address of the management interface when the other switch is being restarted for an upgrade. In this way, the IP addresses and MAC addresses of the management interfaces on the two devices are different. You can log in to different switches for management.

If the MAC address of the management interface on a device is required to be different from the device's system MAC address, run the mac-address mac-address command to change the MAC address of the management interface.

Precautions

The MAC address of the management interface needs to be configured only when an upgrade tool is used to upgrade the stack.

Example

# Configure a MAC address for the management interface.

<HUAWEI> system-view
[~HUAWEI] interface meth 0/0/0

  • Run the port member-group command to add service ports to the stack port. Then the service ports are automatically configured as physical member ports.

  • Run the port mode stack or port mode stack interface command to configure service ports as physical member ports and then run the port member-group command to add the physical member ports to the stack port.

Precautions

  • Physical member ports in a stack port must be the same type. For example, 10GE and 100GE ports cannot be added to the same stack port.

Example

# Add ports from 10GE1/0/1 to 10GE1/0/4 to stack port 1/1.

<HUAWEI> system view
[~HUAWEI] interface stack-port 1/1
[~HUAWEI-Stack-Port1/1] port member-group interface 10ge 1/0/1 to 1/0/4

2: Configuration level

Usage Guidelines

Usage scenario

In a stack, if the owner of the stack MAC address leaves the stack and does not rejoin the stack within the delay in stack MAC address switchover, the master switch uses its own MAC address as the new stack MAC address. If the member switch rejoins the stack within the delay, its own MAC address is still the stack MAC address.

If the delay in MAC address switchover is set to 0, stack MAC address switchover will not be performed.

Precautions

If a stack functions as a Layer 3 gateway, it is recommended that the stack MAC address not be switched.

Default Level

2: Configuration level

Usage Guidelines

During a stack restart, the startup time of member switches varies. If the startup time difference is large, the master, standby, and slave roles may change or some member switches restart multiple times. Assume that three switches A, B, and C set up a stack in chain topology and switch B starts slowly. After the stack restarts, switches A and C finish starting first and compete to be the master switch, whereas switch B has not finished starting. After switch B finishes starting, switches A and C perform stack competition. The switch that fails stack competition restarts again and then joins the stack.

To prevent this problem, before the stack restart, configure the stack competition delay for the switches that start quickly so that stack competition begins after the switch that starts slowly finishes starting.

Example

# Set the stack competition delay to 30s.

<HUAWEI> system-view
[~HUAWEI] stack
[~HUAWEI-stack] stack member 1 competition-delay 30
Info: The stack startup time will be delay 30s.

Usage Guidelines

Usage Scenario

Traffic sent out from a stack port or fabric port can be load balanced based on hash algorithms. You can set hash-mode-id based on the traffic model for load balancing.
  • When the destination MAC address and destination IP address change, you are advised to set hash-mode-id to 1, 5, or 7.
  • When the source MAC address and source IP address change, you are advised to set hash-mode-id to 5 or 6.
  • When the source and destination IP addresses change, you are advised to set hash-mode-id to 8.
  • When the source or destination MAC address changes, you are advised to set hash-mode-id to 9.
  • When the source MAC address changes, you are advised to set hash-mode-id to 1, 2, 6, or 7.
  • In a stack, you are advised to set hash-mode-id to 1.
  • When the destination IP address changes, you are advised to set hash-mode-id to 5 or 6.
  • When the source IP address changes, you are advised to set hash-mode-id to 1, 5, 7, or 9.

Other hash-mode-id values apply to uneven incoming traffic. In this situation, the default hash algorithm is recommended.

Precautions

  • If you run the stack command multiple times, only the latest configuration takes effect.

If the parameter is not specified, the current stack configuration is lost after the device restarts, and the configuration related to the new stack member ID in the configuration file takes effect.

If there are offline configurations related to the new stack member ID on the device, the parameter cannot be specified.

-

Views

Stack Management view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

The stack member ID can be used to identify and manage member switches. Each member switch in a stack has a unique stack member ID.

Precautions

  • After setting the stack member ID, restart the switch to make the configuration take effect.

  • If you specify inherit-config, the switch inherits the original stack configuration after it restarts, including the stack priority, stack domain ID, and physical member port configuration.

    If you do not specify inherit-config, the current stack configuration is lost after the switch restarts, and the configuration related to the new stack member ID in the configuration file takes effect.

    For example, if a switch uses a stack member ID 1 and has the following stack priority configuration:
    #
stack member 1 priority 150
#
    If inherit-config is specified when the stack member ID is changed to 2, member ID 2 will inherit the stack priority configuration of member ID 1 after the switch restarts. For example:
    #
stack member 1 priority 150      // Configuration of member ID 1 becomes the offline configuration.
#
stack member 2 priority 150      // Member ID 2 inherits the stack priority configuration of member ID 1.
#
    If inherit-config is not specified, member ID 2 will not inherit the stack priority configuration of member ID 1 after the switch restarts. For example:
    #
stack member 1 priority 150      // Configuration of member ID 1 becomes the offline configuration, and configuration of member ID 2 is empty.
#
    If the switch already has offline configuration of member ID 2 before restarting, for example:
    #
stack member 1 priority 150
#
stack member 2 priority 200      // The switch already has offline configuration of member ID 2 before restarting
#
    When the stack member ID is changed to 2, inherit-config cannot be specified. The switch will use the configuration of member ID 2 in the configuration file after restarting. For example, 
    #
stack member 1 priority 150      // Configuration of member ID 1 becomes the offline configuration
#
stack member 2 priority 200      // Configuration of member ID 2 in the configuration file takes effect.
#

  • If the configuration file contains offline configuration for the new stack member ID, do not specify inherit-config in the command.

  • Common service port configurations will be lost after the stack member ID is changed and the switch restarts.

Example

# Change the stack member ID of the device to 2.

Usage Guidelines

Usage Scenario

A stack port can forward traffic only after physical member ports are added to the stack port. You can add physical member ports to a stack port using either of the following methods:

  • Run the stack-port command to add service ports to the stack port. Then the service ports are automatically configured as physical member ports.

  • Run the port mode stack or port mode stack interface command to configure service ports as physical member ports and then run the stack-port command to add the physical member ports to the stack port.

Prerequisites

A stack port has been created using the interface stack-port command.

Precautions
  • Physical member ports in a stack port must be the same type. For example, 10GE and 40GE ports cannot be added to the same stack port.

Parameters

None

Views

Stack management view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

You can use the stack upgrade fast command to fast upgrade switches in a stack, which reduces the impact of device upgrade on services.

Precautions

In a fast stack upgrade:

  • Only the stack containing two member switches supports fast upgrade.

  • If 40GE high-speed cables are used to connect stack member devices, you cannot fast upgrade switches from versions earlier than V100R003C00 to V100R003C00 or a later version.

  • When 40GE QSFP+ AOC cables are used for stack connections, the stack cannot be upgraded using fast upgraded from a version earlier than V100R005C10 to V100R005C10 or a later version.

  • During a fast stack upgrade, to shorten traffic interruptions, ensure that upstream and downstream devices are dual-homed to stacked devices using Eth-Trunk.

  • It is recommended a backup IP address be configured for the stack management interface before a fast upgrade to prevent a failure to manage member devices when the stack fails the fast upgrade and splits.

stack upgrade fast rollback-timer

Function

The stack upgrade fast rollback-timer command sets a timeout period for a fast stack upgrade.

By default, a timeout period for a fast stack upgrade is 60 minutes.

Format

stack upgrade fast rollback-timer time

Sets a timeout period.

The value is an integer that ranges from 60 to 240, in minutes.

Views

Stack management view

Default Level

3: Management level

Usage Guidelines

Usage Scenario

In a fast stack upgrade, you can run the stack upgrade fast rollback-timer command to set the timeout period of the standby switch (or group to which the standby switch belongs). If the upgrade fails within the specified timeout period, the standby switch will roll back to the previous version.

Precautions

This command specifies the time taken to upgrade the switch that functions as the standby switch before the upgrade instead of the entire stack system.

Example

# Set a timeout period for a fast stack upgrade to 120 minutes.

<HUAWEI> system-view
[~HUAWEI] stack
[~HUAWEI-stack] stack upgrade fast rollback-timer 120

uplink-port enable

Function

The uplink-port enable command configures the current port as an uplink port.

The undo uplink-port enable command cancels configuring the current port as an uplink port.

By default, an interface is not configured as an uplink port.

CE9860EI, CE5855E, CE6881, CE6881K, CE6881E, CE6863, CE6863K, CE6820, and CE5881 do not support this command.

Format

uplink-port enable

undo uplink-port enable

Parameters

None

Views

GE interface view, 10GE interface view, 25GE interface view, 40GE interface view, 100GE interface view, Eth-Trunk interface view, port group view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

After the enhanced stack DAD function is enabled, comparing the uplink port physical status on stack members is added to DAD competition rules. That is, the switch on which uplink ports are not all Down wins the competition, and the switch on which uplink ports are all Down fails the competition. To specify uplink ports on a switch, run the uplink-port enable command.

Precautions

  • A stack supports the configuration of up to 16 uplink ports.
  • It is not allowed to configure stack member ports and M-LAG peer-link interfaces as uplink ports.
  • It is not allowed to configure Eth-Trunk member ports and aggregated ports as uplink ports.
  • If no uplink ports are configured on a stack member, uplink ports on this member are considered Up.
  • Uplink ports need to transmit uplink traffic. Do not configure the ports that do not transmit uplink port as uplink ports.

Example

# Configure a port as an uplink port.

<HUAWEI> system-view
[~HUAWEI] interface 10ge 1/0/1
[~HUAWEI-10GE1/0/1] uplink-port enable
