Typical Configuration of MCLAG Link

The following is a very basic MCLAG link configuration connecting to NCNs. An administrators configuration may differ.

NOTE The multi-chassis definition after the interface lag xx command. This is what defines the LAG to be able to peer both to Spine-01 and Spine-02.

Spine-01

interface lag 1 multi-chassis
    no shutdown
    no routing
    vlan trunk native 1
    vlan trunk allowed 1-2,4,7,10
    lacp mode active
    lacp fallback
    spanning-tree bpdu-guard
    spanning-tree port-type admin-edge
interface 1/1/1
    no shutdown
    mtu 9198
    lag 1

Spine-02

interface lag 1 multi-chassis
    no shutdown
    no routing
    vlan trunk native 1
    vlan trunk allowed 1-2,4,7,10
    lacp mode active
    lacp fallback
    spanning-tree bpdu-guard
    spanning-tree port-type admin-edge
