Configuring MLAGs

This section provides the commands used to configure MLAGs and display information about those configured.

To create an MLAG (Multi-switch Link Aggregation Group) peer switch association structure, use the following command:
create mlag peer peer_name
To delete a peer switch, use the following command:
delete mlag peer peer_name
To associate an MLAG peer structure with an MLAG peer switch IP address, use the following command:
configure mlag peer peer_name ipaddress peer_ip_address {vr VR}
To unconfigure the association, use the following command:
unconfigure mlag peer peer_name ipaddress
To configure the time interval between health check hello packets exchanged between MLAG peer switches, use the following command:
configure mlag peer peer_name interval msec
To unconfigure the time interval setting and reset the interval to the default of 1000 ms, use the following command:
unconfigure mlag peer peer_name interval
To bind a local port or LAG (Link Aggregation Group) to an MLAG specified with an integer identifier, use the following command:
enable mlag port port peer peer_name id identifier
To disable a local port or LAG from an MLAG, use the following command:
disable mlag port port
To set a preference for having a fast convergence time or conserving access lists, use the following command:
configure mlag ports convergence-control [conserve-access-lists | fast]

Note
Executing the refresh policy command with MLAG configuration may result in health check hellos not reaching the CPU. To avoid MLAG peer connectivity disruption, you can either execute the disable access-list refresh blackhole command or temporarily increase the peer hello interval to a large value (for instance, 10000 ms) and reset it back once refresh policy is complete.
