User Guidelines
The VPC domain MAC address must be the same on both MLAG peer
devices. The MAC address is a unicast MAC address in aa:bb:cc:dd:ee:ff
format and is not equal to the physical MAC address of either the primary
VPC or secondary VPC device. The configured VPC domain MAC address is
exchanged during role election and, if configured differently on the peer
devices, VPC does not become operational.
The configured domain MAC address is present in the LACP PDUs and STP
BPDUs that are sent on VPC member ports if VPC primary device election
takes place after the VPC MAC address is configured. When the VPC MAC
address is configured after the VPC primary device is elected, already agreed
upon operational VPC MAC address is used in the LACP PDUs and STP
BPDUs instead of the configured VPC MAC address.
Command History
Introduced in version 6.2.0.1 firmware.
