Restrictions of using NetStream with other features

Table 14-4 Restrictions of using NetStream with other features

Feature

Use Precautions

sFlow

NetStream and sFlow cannot be configured on the same device.

Mirroring

  • On the CE6880EI and CE5880EI, NetStream and port mirroring can be configured on the same interface, and NetStream does not conflict with MQC-based traffic mirroring, simplified traffic mirroring, or VLAN mirroring.

  • On the CE6875EI or CE6870EI:
    • When inbound NetStream sampling is configured to use snoop resources, you can configure port mirroring and inbound NetStream on the same interface, and inbound NetStream does not conflict with MQC-based traffic mirroring, simplified traffic mirroring, or VLAN mirroring.
    • When inbound NetStream sampling is not configured to use snoop resources, port mirroring and NetStream cannot be configured on the same interface, and NetStream conflicts with MQC-based traffic mirroring, simplified traffic mirroring, and VLAN mirroring. After NetStream is configured on an interface, do not configure any MQC-based traffic mirroring, simplified traffic mirroring, or VLAN mirroring to contain this interface. If the NetStream and mirroring functions (MQC-based traffic mirroring, simplified traffic mirroring, or VLAN mirroring) are configured on the same interface, they cannot take effect simultaneously.
  • On other models:
    • NetStream and port mirroring cannot be configured on the same interface. NetStream conflicts with MQC-based traffic mirroring, simplified traffic mirroring, and VLAN mirroring. After NetStream is configured on an interface, do not configure any MQC-based traffic mirroring, simplified traffic mirroring, or VLAN mirroring to contain this interface. If the NetStream and mirroring functions (MQC-based traffic mirroring, simplified traffic mirroring, or VLAN mirroring) are configured on the same interface, they cannot take effect simultaneously.

    • Mirrored packets cannot be sampled.

FCoE

On an FCoE network, the switch collects statistics only about Layer 2 attributes in packets.

BFD

In V200R003C00 and later versions, after NetStream sampling is configured on the CE8868EI, CE8861EI, CE8850-64CQ-EI, CE6880EI, CE6875EI, CE6865EI, CE6857EI, or CE5880EI, BFD packets sampled by NetStream cannot be exported.

TRILL

On a TRILL network, the device collects statistics only about Layer 2 attributes in packets.

VLAN

  • In V200R003C00 and earlier versions, only the CE8860EI, CE8850EI, CE6875EI, CE6870EI, and CE5810EI perform NetStream sampling for packets discarded in VLAN check. In V200R005C00 and later versions, CE8800, CE7800, CE6800, and CE5800 series switches perform NetStream sampling for packets discarded in VLAN check.

  • For packets from super-VLANs or sub-VLANs, the device creates a NetStream flow based only on outer VLAN IDs.

QinQ

For packets carrying multiple tags, the switch creates a NetStream flow based on outer VLAN IDs.

Multicast

On a CE switch except CE6880EI, CE6875EI, CE6870EI, and CE5880EI, NetStream cannot sample the Layer 2 information in downstream Layer 2 and Layer 3 multicast traffic or IPv6 multicast packets.

VPN

  • When NetStream sampling is configured for outbound Layer 3 traffic between VPNs, routing information cannot be collected.
  • When a main interface and its Layer 3 sub-interfaces are in different VPNs and NetStream is configured on the main interface, the traffic passing through the Layer 3 sub-interface can be sampled. Routing information about the main interface is collected, but routing information about the Layer 3 interface is not collected.

VPLS

VPLS packets cannot be sampled.

MPLS

When inbound NetStream sampling is configured on a Layer 3 sub-interface of a CE6875EI or CE6870EI series switch, the switch cannot sample incoming MPLS packets on the Layer 3 sub-interface.

QoS

  • NetStream sampling is on the basis of original packets. After the forwarding behavior is modified (for example, policy routing is applied) or information about the packets to be forwarded is modified (for example, ACL or QoS is applied), the modification cannot be shown in the NetStream statistics.

  • On a CE switch except CE6880EI, CE6875EI, CE6870EI, and CE5880EI, NetStream can sample outgoing packets even if the packets are discarded by CAR, traffic shaping, or Deny action.

VXLAN

  • Starting from V200R001C00, NetStream can sample the original Ethernet frame information in VXLAN packets. When VXLAN flexible flow statistics collection is configured, flows can be created based only on the inner IPv4 packets of VXLAN packets, but cannot be created based on the IPv6 packets or Ethernet frame headers in VXLAN packets. After VXLAN flexible flow statistics collection is configured on an interface, this interface cannot collect statistics on IPv4 original flows.

  • On a switch that performs VXLAN encapsulation, except CE6880EI, CE6875EI, CE6870EI, and CE5880EI, NetStream cannot sample the VXLAN packets on outbound interfaces.
  • After IPv4 original flow sampling is configured on a switch, the switch cannot obtain routing information from forwarded VXLAN packets.

  • On a CE6875EI or CE6870EI series switch that decapsulates VXLAN packets, when inbound NetStream sampling is configured on a Layer 3 sub-interface, incoming VXLAN packets cannot be sampled on the Layer 3 sub-interface.

Local attack defense

  • On the CE6880EI and CE5880EI, NetStream sampling can only be performed in enhanced mode. In this mode, sampled packets are not sent to the CPU for processing.
  • On other models:
    • Since V200R001C00, the device sends sampled packets to the CPU for processing. 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, some sampled packets to be sent to the CPU are discarded, decreasing the NetStream sampling ratio. When the CPU usage falls below 65%, the switch increases the CAR value of sampled packets by 500 pps every 20 seconds until the CAR value is restored to the original setting.
    • On the CE8868EI, CE8861EI, CE8850-64CQ-EI, CE6875EI, CE6857EI, and CE6865EI, NetStream sampling can be performed in enhanced mode. In this mode, sampled packets are not sent to the CPU for processing.

ARP security

On a CE switch except CE6880EI, CE6875EI, CE6870EI, and CE5880EI, if both NetStream and interface-based ARP rate limiting are configured, interface-based ARP rate limiting is inaccurate. The maximum number of ARP packets sent from interfaces to the CPU is the ARP rate limit plus the number of ARP packets sampled by NetStream.

SVF consisting only fixed switches

  • When working in hybrid or centralized forwarding mode, a leaf switch does not support NetStream.
  • A leaf switch with NetStream configured cannot change from distributed forwarding mode to hybrid or centralized forwarding mode. To change the forwarding mode of a leaf switch, delete the NetStream configuration on the leaf switch first.
  • The CE5855EI supports NetStream IPv6 when functioning as a leaf switch.
  • After NetStream sampling is configured in the outbound direction of a physical interface or Eth-Trunk, the traffic on Layer 3 or Layer 2 sub-interfaces can be sampled when the traffic passes two or more switches. The physical interface or Eth-Trunk indexes are filled in the sampled packets, and the routing information in the packets on Layer 3 or Layer 2 sub-interfaces cannot be collected.

NetStream use restrictions

Common use restrictions:
  • NetStream cannot sample protocol packets to be sent to the CPU.
  • NetStream Top Talkers, NetStream IP traffic statistics collection, and NetStream Layer 2 flow statistics collection cannot be configured on the same interface.
  • For packet fragments, NetStream can sample only the first fragment of a packet.
  • In the NetStream sampling service, there may be a difference of 5% or lower between collected statistics and actual traffic statistics.

  • When sampling outgoing packets, the device does not record source VLAN information in the packets. Source VLAN information is recorded as 0. When sampling incoming packets, the device does not record destination VLAN information. Destination VLAN information is recorded as 0.

  • When sampling packets, NetStream does not resolve the option fields in IPv4 packets and extended headers in IPv6 packets.

  • When a packet has multiple next hops, the device records any one of these next hops in routing information during sampling. The route field in NetStream packets is updated periodically based on the aging time of NetStream flows, but not updated based on the routing table in real time.

  • The switch cannot encapsulate NetStream packets using VXLAN or MPLS before forwarding them. When configuring NetStream sampling, do not choose to send NetStream packets to the collector over the VXLAN or MPLS tunnel.

Restrictions on the CE6880EI and CE5880EI:
  • The switch cannot send NetStream packets through the management interface.
  • After NetStream sampling is configured on the physical interface, Eth-Trunk, and Eth-Trunk member interface, the switch can sample packets on their Layer 3 and Layer 2 sub-interfaces. However, if NetStream sampling is configured on the physical interface, Eth-Trunk, and its Layer 3 and Layer 2 sub-interfaces, the switch can sample only the packets on these interfaces.
  • When inbound NetStream sampling is configured on an interface, only the inbound interface information is displayed in the statistics. When outbound NetStream sampling is configured on an interface, only the outbound interface information is displayed in the statistics.
  • In a fast stack upgrade or downgrade scenario, when a stack is downgraded from V200R005C00 or a later version to V200R003C00, interfaces on the standby device enter the Error-Down state.

  • NetStream does not sample packets to be discarded.

  • NetStream does not sample packets to be sent to the CPU.

  • When the forwarding mode on the device is cut through, the switch does not support NetStream. To use NetStream, change the forwarding mode to store-and-forward.

Restrictions on the CE6870EI:
  • In V200R003C00 and earlier versions, when NetStream sampling is configured in the inbound direction of a physical interface or an Eth-Trunk, the switch cannot sample packets on Layer 3 or Layer 2 sub-interfaces. When NetStream sampling is configured in the outbound direction of a physical interface or an Eth-Trunk, the switch can sample packets on Layer 2 sub-interfaces but cannot sample packets on Layer 3 sub-interfaces. The interface index in the sampled packets is the main interface index, and routing information in the packets on Layer 2 sub-interfaces cannot be sampled.

  • In V200R005C00 and later versions, when NetStream sampling is configured on a physical interface or an Eth-Trunk, the switch can sample packets on Layer 2 and Layer 3 sub-interfaces. The interface index in the sampled packets is the main interface index, and the routing information in the packets on Layer 2 and Layer 3 sub-interfaces cannot be collected.
  • The following services are in descending order of priority: M-LAG unidirectional isolation, MQC (traffic policing, traffic statistics collection, and packet filtering), querying the outbound interface of packets with specified 5-tuple information, source MAC address, and destination MAC address, local VLAN mirroring, sFlow, NetStream, and VLANIF interface statistics collection. When the services are configured on an interface in the outbound direction, only the service with the highest priority takes effect. For example, when both packet filtering and VLANIF interface statistics collection are configured on a VLANIF interface, packet filtering takes effect.

    For sFlow and NetStream, the preceding limitations apply only to Layer 2 sub-interfaces and Layer 3 sub-interfaces.

  • When NetStream sampling is configured for incoming multicast, broadcast, and unknown unicast packets, the packet statistics do not contain outbound interface information. When NetStream sampling is configured for incoming known unicast packets, the following events occur:
    • If the outbound interface is a Layer 3 main interface, the packet statistics contain outbound interface information.
    • If the outbound interface is a Layer 3 sub-interface, the packet statistics are about the Layer 3 main interface corresponding to this sub-interface.
    • If the outbound interface is an interface of other types, the packet statistics do not contain outbound interface information.
  • On the device that encapsulates or decapsulates tunneling protocol packets, outbound NetStream cannot sample the encapsulated tunneling protocol packets on Layer 3 sub-interfaces.

  • Configuring outbound NetStream sampling is not recommended because it will lower the forwarding capability of the switch.

Restrictions on the CE6875EI:
  • The following services are in descending order of priority: M-LAG unidirectional isolation, MQC (traffic policing, traffic statistics collection, and packet filtering), querying the outbound interface of packets with specified 5-tuple information, source MAC address, and destination MAC address, local VLAN mirroring, sFlow, NetStream, and VLANIF interface statistics collection. When the services are configured on an interface in the outbound direction, only the service with the highest priority takes effect. For example, when both packet filtering and VLANIF interface statistics collection are configured on a VLANIF interface, packet filtering takes effect.

When NetStream sampling is configured in the outbound direction of a physical interface, an Eth-Trunk, or an Eth-Trunk member interface, the switch can sample only the packets on Layer 2 sub-interfaces, but cannot sample packets on Layer 3 sub-interfaces. The interface index in the sampled packets is the main interface index, and routing information in the packets on Layer 2 sub-interfaces cannot be sampled.

    • In V200R005C00 and later versions, when NetStream sampling is configured on a physical interface, an Eth-Trunk, or an Eth-Trunk member interface, the switch can sample packets on Layer 3 and Layer 2 sub-interfaces. The interface index in the sampled packets is the main interface index, and the routing information in the packets on Layer 2 and Layer 3 sub-interfaces cannot be collected.

    • When NetStream sampling is configured on a physical interface, an Eth-Trunk, and its Layer 3 and Layer 2 sub-interfaces, the switch can sample only the packets on these interfaces.

    • When NetStream sampling is configured for incoming multicast, broadcast, and unknown unicast packets, the packet statistics do not contain outbound interface information. When NetStream sampling is configured for incoming known unicast packets, the following events occur:
      • If the outbound interface is a Layer 3 main interface, the packet statistics contain outbound interface information.
      • If the outbound interface is a Layer 3 sub-interface, the packet statistics are about the Layer 3 main interface corresponding to this sub-interface.

  • Restrictions in enhanced mode:

    • The switch cannot send NetStream packets through the management interface.
    • After NetStream sampling is configured on the physical interface, Eth-Trunk, and Eth-Trunk member interface, the switch can sample packets on their Layer 3 and Layer 2 sub-interfaces.

    • When inbound NetStream sampling is configured on an interface, only the inbound interface information is displayed in the statistics. When outbound NetStream sampling is configured on an interface, only the outbound interface information is displayed in the statistics.
    • In a fast stack upgrade or downgrade scenario, when a stack is downgraded from V200R005C00 or a later version to V200R003C00, interfaces on the standby device enter the Error-Down state.

  • When NetStream sampling is configured for outgoing packets and the inbound interface is a Layer 3 or Layer 2 sub-interface, the inbound interface recorded in statistics packets is the main interface corresponding to this Layer 3 or Layer 2 sub-interface.

  • In V200R003C00 and earlier versions, when NetStream sampling is configured on a physical interface or an Eth-Trunk of a CE switch except the CE5810-48T4S-EI, the switch cannot sample packets on Layer 3 or Layer 2 sub-interfaces.
  • In V200R005C00 and later versions, when NetStream sampling is configured in the inbound direction of a physical interface or an Eth-Trunk of a CE switch except the CE5810-48T4S-EI, the switch can sample packets on Layer 2 and Layer 3 sub-interfaces.
