Excluding specific ports from fast port span
To exclude a port from Fast Port Span while leaving Fast Port Span enabled globally, enter
commands such as the following.
Brocade(config)#fast port-span exclude ethernet 1
Brocade(config)#write memory
To exclude a set of ports from Fast Port Span, enter commands such as the following.
Brocade(config)#fast port-span exclude ethernet 1 ethernet 2 ethernet 3
Brocade(config)#write memory
To exclude a contiguous (unbroken) range of ports from Fast Span, enter commands such as the
following.
Brocade(config)#fast port-span exclude ethernet 1 to 24
Brocade(config)#write memory
Syntax: [no] fast port-span [exclude ethernet <port> [ethernet <port>] | to [<port>]]
Specify the port variable in one of the following formats:
• FWS, FCX, and ICX stackable switches – stack-unit/slotnum/portnum
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• ICX devices – slotnum/portnum
• FESX compact switches – portnum
To re-enable Fast Port Span on a port, enter a command such as the following.
Brocade(config)#no fast port-span exclude ethernet 1
Brocade(config)#write memory
This command re-enables Fast Port Span on port 1 only and does not re-enable Fast Port Span on
other excluded ports. You also can re-enable Fast Port Span on a list or range of ports using the
syntax shown above this example.
To re-enable Fast Port Span on all excluded ports, disable and then re-enable Fast Port Span by
entering the following commands.
Brocade(config)#no fast port-span
Brocade(config)#fast port-span
Brocade(config)#write memory
