MLAG Commands
Operational Concept
A multi-chassis link aggregation group (MLAG) is a pair of links that terminate on
two cooperating switches and appear as an ordinary link aggregation group (LAG).
The cooperating switches are MLAG peer switches and communicate through an
interface called a peer link. While the peer link’s primary purpose is exchanging
MLAG control information between peer switches, but also carries data traffic from
devices that are attached to only one MLAG peer and have no alternative path. An
MLAG domain consists of the peer switches and the control links that connect
these switches.

MLAG Configuration
â—† MLAG must be enabled globally using the mlag command.
â—† The MLAG domain ID and peer link must be set using the mlag peer-link
command.
