Configuring Link Aggregation

Configure the timeout interval, if desired.

Modifications to priority and timeout interval are effective only before the 

keep-alive protocol is enabled. Once enabled, MLAG switches contest in 

an election to select the primary and secondary switch. The election is 

non-preemptive. 

3 Configure the peer-link. On each MLAG peer:

• Configure a port-channel as the peer-link for the MLAG devices. It is 

recommended that the administrator use dynamic LAGs as port-

channels.

• It is strongly recommended that the MLAG peer LAG consist of 

multiple physical links with sufficient bandwidth to carry all MLAG 

traffic expected to be carried by either MLAG peer.

• Disable spanning tree on the peer-link.
• Enable trunking on the peer-link. Remove any non-MLAG VLANs 

from the peer-link trunk port. VLANs cannot be configured to contain 

both MLAG ports and non-MLAG (non-redundant) ports.

• Ensure that the peer-link has a native VLAN configured.
• Optionally, configure UDLD on the peer-link to detect and shut down 

unidirectional links.

• Associate the port-channel with physical links.
