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.

(Optional) Configuring the Interface Status When the Peer-Link Fails

(Optional) Configuring the Interface Status When the Peer-Link Fails

Context

On a dual-homing Ethernet, VXLAN, or IP network where M-LAG is deployed, when the peer-link fails but the DAD status is normal, interfaces except the management interface, peer-link interface, and stack interface on the backup device all enter the Error-Down state. When the faulty peer-link is restored, the M-LAG interface in Error-Down state goes Up after 2 minutes by default and other interfaces in Error-Down state go Up automatically.

In practice, uplink interfaces running routing protocols or DAD-enabled heartbeat interfaces should not enter the Error-Down state. You can configure the interface whether to enter the Error-Down state according to the actual situation.

Table 4-10 describes the Error-Down state of interfaces when the peer-link fails but the DAD status is normal.

Table 4-10 Error-Down state of interfaces when the peer-link fails but the DAD status is normal

Device Configuration

Ethernet, VXLAN, or IP Network Where M-LAG Is Deployed

Default setting

Interfaces except the management interface, peer-link interface, and stack interface on the backup device all enter the Error-Down state.

Device where m-lag unpaired-port suspend is configured

Only the M-LAG member interface and the interface configured with m-lag unpaired-port suspend are in Error-Down state.

Device where m-lag unpaired-port reserved is configured

Interfaces except the interface configured with m-lag unpaired-port reserved, management interface, peer-link interface, and stack interface on the backup device all enter the Error-Down state.

Device where both m-lag unpaired-port suspend and m-lag unpaired-port reserved are configured

Only the M-LAG member interface and the interface configured with m-lag unpaired-port suspend are in Error-Down state.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run m-lag unpaired-port reserved

    The interface is configured not to enter the Error-Down state when the peer-link fails but the DAD status is normal.

    • You can configure m-lag unpaired-port suspend on other interfaces of the backup device so that the specified interface is configured to automatically enter the Error-Down state when the peer-link fails but the DAD status is normal.

    • You are advised to configure this command on interfaces of both the M-LAG master and slave devices, so the Error-Down state of interfaces is consistent after an active/standby switchover of the M-LAG master and backup devices.

    • This command cannot be configured on the peer-link interface and M-LAG member interfaces.

  4. Run commit

    The configuration is committed.
