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.
