vsx-sync mclag-interfaces

Syntax

vsx-sync mclag-interfaces

no vsx-sync mclag-interfaces

Description

Enables the VSX synchronization of VSX LAG interface associations and attributes on the primary VSX switch to the secondary peer switch. The Usage section in this topic provides a listing of specific associations and attributes that are synchronized to the secondary switch.

The no form of this command removes VSX synchronization of global VSX LAG and attributes, but it does not remove the existing VSX LAG feature configurations from the secondary peer switch.

Command context

config-vsx

Authority

Administrators or local user group members with execution rights for this command.

Usage

The VSX LAG interface associations and attributes that support VSX synchronization are for example:

Interface associations:

  • Access lists

  • Policies

  • QoS

  • Port filters

  • Rate limits

  • VLANs

Supported attributes:

  • LAG description

  • LACP

  • Loop protect

  • QoS trust

  • sFlow

  • STP

This configuration overrides the existing VSX synchronization associations created under the VSX LAG interface context. Also with this configuration, the system blocks further configuration of VSX synchronization associations under the VSX LAG context.

Examples

The first four lines in the following example show the creation and configuration of a VSX LAG. The last two lines of the example show the enabling of VSX synchronization for VSX LAG interface associations and attributes. 

switch(config)# interface lag 1 multi-chassis
switch(config-lag-if)# access-list ip MY_IP_ACL in
switch(config-lag-if)# rate-limit broadcast 50 kbps
switch(config-lag-if)# qos trust cos
switch(config-lag-if)# exit
switch(config)# vsx
switch(config-vsx)# vsx-sync mclag-interfaces

Disabling the VSX synchronization of VSX LAG interface associations and attributes: 

switch(config)# vsx
switch(config-vsx)# no vsx-sync mclag-interfaces
