FCX IronStack configuration
NOTE
Do not connect stacking ports to non-stacking ports. Stacking ports have a proprietary packet
format that renders them incompatible with regular ports even when they are forwarding regular
packets. In linear topologies, make sure that end units have only one stacking port configured
(secure-setup automatically configures only one stacking port for an end unit).
Configuring a single stack port
To configure a single stack port, enter a command similar to the following.
Brocade(config)# stack unit 3
Brocade(config-unit-3)# stack-port 3/2/1
Syntax: [no] stack-port <stack-unit/slotnum/portnum>
If you enter an incorrect stack port number, you will get an error similar to the following.
Brocade(config-unit-3)# stack-port 3/4/1
Error! port 3/4/1 is invalid
Brocade(config-unit-3)# stack-port 3/2/1
To return both ports to stacking status, enter the no stack-port command on the single stacking
port. This converts both ports to stacking ports. By default, if both ports are stacking ports, they are
displayed by the system only when stacking is enabled. If only one port is configured as a stacking
port, the system always displays this port.
