Hierarchy Level


Configure Interchassis Control Protocol (ICCP) between the multichassis link aggregation group (MC-LAG) peers. ICCP replicates forwarding information, validates configurations, and propagates the operational state of the MC-LAG members.


If you do not include this statement, no ICCP protocol tracing operations are performed.


traceoptions—Set Interchassis Control Protocol (ICCP) tracing options.

local-ip-address—Specify the source address where the ICCP packet is routed.

session-establishment-hold-time—Specify if the chassis takes over as the primary at the ICCP session.

authentication-key —Specify TCP Message Digest 5 (MD5) option for an ICCP TCP session.

peer ip-address—Specify the IP address of the peer that hosts an MC-LAG. You must configure ICCP for both peers that host the MC-LAG.

redundancy-group-id-list—Specify the redundancy groups between two ICCP peers. The value you assign to this option must match the value you assign to the redundancy-group-id option that you configure on the MC-AE interface. If the value differs, when you commit the changes, the system reports a commit check error.

liveness-detection—Specify Bidirectional Forwarding Detection (BFD) protocol options.

Required Privilege Level
