About Multi-Chassis Trunk (MCT)
18
By default , MCT acts as a hub for STP, or RSTP. Switches connected to MCT can run STP normally.
When STP, RSTP, or MSTP is enabled, the L2 protocol forwarding configuration is ignored and has
no effect.
To configure L2 protocol forwarding globally, enter a command such as the following.
Brocade(config)#cluster-l2protocol-forward
To disable L2 protocol forwarding on an interface, enter a command such as the following.
Brocade(config-if-e1000-1/2)#cluster-l2protocol-foward disable
To remove L2 protocol forwarding configuration on an interface, enter a command such as the
following
Brocade(config-if-e1000-1/2)#no cluster-l2protocol-foward <enable | disable>
Syntax: [no]cluster-l2protocol-forward [enable | disable]
Interface level configuration overwrites the global level configuration.
