Clearing MCT VLAN-specific MAC addresses
To clear MCT VLAN-specific MAC addresses in the system, enter a command such as the following.
device# clear mac cluster AGG-1 vlan 1 local
Syntax: clear mac cluster { cluster_id | cluster-name } vlan vlan_id { local | remote }
Clearing cluster client vlan-specific MACs
To clear cluster client-specific MAC addresses in the system, enter a command such as the following.
device# clear mac cluster AGG-1 vlan 2 client 1 local
Syntax: clear mac cluster {cluster_id | cluster-name } vlan vlan_id client client_name { local |
remote }
Displaying MDUP packet statistics
To display the statistics of MDUP packets, enter a command such as the following.
device#show mac mdup-stats

Syncing router MAC addresses to peer MCT devices
The MCT cluster device uses a router MAC address to identify the packets that are addressed to the
switch. Such packets may be received by a peer cluster device. The peer device switches packets
over the ICL to the local MCT device to be routed properly.
Dynamic trunks
The MCT client creates a single dynamic trunk group toward the MCT cluster devices. The dynamic
trunk group consists of two trunk groups, each of which is configured on one of the MCT devices. A
dynamic trunk group runs Link Aggregation Control Protocol (LACP).
For the two dynamic trunk groups of the MCT to behave as a single trunk group from the MCT client’s
perspective, both of the dynamic trunk groups should have the same LACP system ID and key,
referred to as the MCT system ID and MCT key.
