Configuration Guide - Ethernet Switching

CloudEngine 8800, 7800, 6800, and 5800 V200R003C00

This document describes the configuration of Ethernet services, including configuring MAC address table, link aggregation, VLANs, MUX VLAN, Voice VLAN, VLAN mapping, QinQ, GVRP, VCMP, STP/RSTP/MSTP, VBST, SEP, RRPP, ERPS, LBDT, and Layer 2 protocol transparent transmission.

Configuring an Interface as a Peer-link Interface

Configuring an Interface as a Peer-link Interface

Context

A peer-link is a direct aggregated link between two devices configured with M-LAG. It is used to exchange protocol packets and transmit some traffic, and ensures normal running of M-LAG.

Prerequisites

The direct link between two devices configured with M-LAG has been configured as an aggregated link.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface eth-trunk trunk-id

    The Eth-Trunk interface view is displayed.

  3. Run trunkport interface-type { interface-number1 [ to interface-number2 ] } &<1-n>

    NOTE:

    n depends on the assign forward eth-trunk mode command.

    A member interface is added to the Eth-Trunk.

    When you add member interfaces to an Eth-Trunk in a batch, if one interface cannot be added to the Eth-Trunk, all subsequent interfaces in the batch cannot be added to the Eth-Trunk, either.

    On the CE5810EI, run the trunkport interface-type { interface-number1 [ to interface-number2 ] } &<1-8> command to add member interfaces.

  4. Run mode lacp-static

    The Eth-Trunk is configured to work in static LACP mode.

    By default, an Eth-Trunk works in manual load balancing mode. To ensure M-LAG reliability, you are advised to configure the Eth-Trunk to work in static LACP mode.

  5. Run undo stp enable

    STP is disabled on the interface.

    By default, STP is enabled on an interface.

    NOTE:

    STP needs to be disabled because two devices need to be simulated into one STP root bridge and the directly connected interface cannot be blocked.

  6. Run peer-link peer-link-id

    The interface is configured as a peer-link interface.

    By default, no interface is configured as a peer-link interface.

    • An interface configured as a peer-link interface joins all VLANs by default.

    • An interface configured as a peer-link interface cannot be configured with any service.

    • If the ERPS control VLAN, TRILL carrier VLAN, or FCoE VLAN needs to be configured, perform 7 to remove the peer-link interface from the control VLAN, carrier VLAN, or FCoE VLAN. Otherwise, the control VLAN, carrier VLAN, or FCoE VLAN cannot be configured.

    • If the network-side VLANIF interface is configured, perform 7 to remove the peer-link interface from the VLAN. Otherwise, heartbeat detection may take ineffective.

  7. (Optional) Run port vlan exclude { { vlan-id1 [ to vlan-id2 ] } &<1-10> }

    The VLANs not allowed by the peer-link interface are specified.

    By default, no allowed VLAN is specified on a peer-link interface.

  8. Run commit

    The configuration is committed.
