Optional cluster operation features
A cluster can operate in two modes:
Cluster Failover Mode
Fast-failover (default) - As soon as the ICL interface goes down the CCP goes down. All the remote
MACs are flushed.
Slow-failover - Even if the ICL interface goes down the CCP waits for the hold-time before making
the CCP down. Remote MACs are flushed only when the CCP is down.
To disable the fast-failover mode, enter a command such as the following.
Brocade(config-cluster-TOR)#peer 1.1.1.1 disable-fast-failover
Syntax: [no] peer disable-fast-failover
Client isolation mode
NOTE
The CLI will allow modification of the client-islolation mode on MCT cluster nodes even when the
cluster is deployed. You must create the same isolation mode on both cluster nodes.
The client operates in the following mode:
Strict mode: When the CCP goes down, the client interfaces on both the cluster nodes are
administratively shutdown. In this mode, the client is completely isolated from the network if CCP is
not operational.
Brocade(config-cluster-TOR)#client-isolation strict
Syntax: [no] client-isolation strict
Shutdown all client interfaces
Use the client-interfaces shutdown command when preforming a hitless-upgrade operation. This
command can be used to shutdown all the local client interfaces in the cluster. This would result in
failover of traffic to the cluster peer.
Brocade(config-cluster-TOR)#client-interfaces shutdown
Syntax: [no] client-interfaces shutdown
Client interfaces delay
Use the client-interfaces delay command to set the delay before brining up the CCEP port. This
command is used to set the delay, so that after a node is reloaded, with just L2vpn peer alone, the
delay to bring up the CCEP port will be the designated value.
Brocade(config-cluster-TOR)#client-interfaces delay 60
Syntax: [no] client-interfaces delay
The default value for delay is 30 seconds. The acceptable values range between 20 to 600
seconds.
