Configuring Multi-chassis Link Aggregation Quick Steps for Configuring MCLAG

Quick Steps for Configuring MCLAG
Follow the steps below for a quick tutorial on configuring MCLAG between two switches. Additional
information on how to configure MCLAG is provided in the section “Configuring MCLAG” on
page 10-27.
Note. Although some parameters are configurable at runtime, it is strongly recommended that the entire
MCLAG configuration be completed prior to rebooting the switches. This will avoid a temporary
mismatch of configurations between the peer switches as well as prevent multiple reboots. Additionally,
the switch must be rebooted and MCLAG operational before performing any additional configuration.
1 Configure a globally unique chassis identifier using the multi-chassis chassis-id command as shown
below:
OS10K [Chassis 1] -> multi-chassis chassis-id 1
OS10K [Chassis 2] -> multi-chassis chassis-id 2
2 Configure a globally unique chassis group identifier for the multi-chassis domain using the multi-
chassis chassis-group command as shown below:
OS10K [Chassis 1] -> multi-chassis chassis-group 10
OS10K [Chassis 2] -> multi-chassis chassis-group 10
3 Create a virtual fabric link between chassis peers using the multi-chassis vf-link create command as
shown below:
OS10K [Chassis 1] -> multi-chassis vf-link create
OS10K [Chassis 2] -> multi-chassis vf-link create
4 Add the physical ports as members of the virtual fabric link on each peer switch using the
multi-chassis vf-link member-port command as shown below:
OS10K [Chassis 1] -> multi-chassis vf-link member-port 1/1
OS10K [Chassis 1] -> multi-chassis vf-link member-port 1/17
OS10K [Chassis 1] -> multi-chassis vf-link member-port 3/1
OS10K [Chassis 1] -> multi-chassis vf-link member-port 3/17
OS10K [Chassis 2] -> multi-chassis vf-link member-port 2/1
OS10K [Chassis 2] -> multi-chassis vf-link member-port 2/17
OS10K [Chassis 2] -> multi-chassis vf-link member-port 4/1
OS10K [Chassis 2] -> multi-chassis vf-link member-port 4/17
5 Verify the chassis identifier settings using the show multi-chassis status command as shown below:
OS10K [Chassis 1] -> show multi-chassis status
