5.27. Multi-chassis Link Aggregation Commands
This section describes the commands you use to configure and display Multi-Chassis Link Aggregation (MLAG).
MLAG allows links that are physically connected to two different devices to appear as a single Port Channel to a
third device.
Note: MLAG can support RSTP and IGMP Snooping. The configuration of RSTP and IGMP Snooping on peers of MLAG must
be the same to guarantee that MLAG can work correctly.
5.27.1. mlag
This command enables Multi-Chassis Link Aggregation (MLAG) globally.
Format mlag
Default Disable
Mode Global Config
5.27.2. no mlag
This command disables MLAG globally.
Format no mlag
Mode Global Config
5.27.3. mlag domain
This command creates a MLAG domain with the specified domain ID. Only one MLAG domain can be created on
a given device. The domain-id of the MLAG domain should be equal to the one configured on the other MLAG
peer with which this device wants to form a MLAG pair. The configured MLAG domain-ids are exchanged during
role election and if they are configured differently on the peer devices, the MLAG does not become operational.
Domain-id is used to derive the auto-generated MLAG virtual MAC address that is used in the actor ID field in
the LACP PDUs.
Format mlag domain <1-255>
Default None
Mode Global Config
