1. Create a cluster client instance by entering the following command.
BigIron RX(config-cluster-TOR)# client client-2
2. Configure the client RBridge ID by entering the following command.
BigIron RX(config-cluster-TOR-client-2)# rbridge-id 200
3. Create a cluster client interface by entering the following command.
BigIron RX(config-cluster-TOR-client-2)# client-interface ethernet 1/4
4. Deploy the cluster client by entering the following command.
BigIron RX(config-cluster-TOR-client-2)# deploy

Optional MCT cluster commands
The following commands are optional for MCT cluster configuration.
Configuring cluster failover mode
A cluster can operate in two modes:
•
Fast-failover mode - When an ICL interface goes down, the CCP goes down. All the remote MAC
entries are flushed.
•
Slow-failover mode - Even if an ICL interface goes down, the CCP waits for the hold time before
the CCP goes down. Remote MAC entries are flushed only when the CCP is down.
NOTE
Fast-failover mode is the default mode.
NOTE
Brocade recommends configuring the same mode on each of the cluster switches.
To disable the fast-failover mode, enter a command such as the following.
BigIron RX(config-cluster-TOR)# peer 1.1.1.1 disable-fast-failover
Syntax: [no] peer <peer-ip> disable-fast-failover
The <peer-ip> variable specifies the IP address of the peer.
The no form of the command enables fast-failover mode.
Configuring client isolation mode
NOTE
Brocade recommends configuring the same mode on each of the cluster switches.
The clients can operate in two modes:
•
Loose mode - When the CCP goes down, the client performs the master and slave negotiation.
After the negotiation, if the keepalive VLAN is configured, then the slave shuts down its client
ports, whereas the master client ports continue to forward the traffic. The loose mode is the
default mode.
