• An STP Configuration BPDU has been received on the port, thus indicating the presence of
another bridge on the port.
You also can explicitly exclude individual ports from Fast Port Span if needed. For example, if the
only uplink ports for a wiring closet switch are Gbps ports, you can exclude the ports from Fast Port
Span.
Disabling and re-enabling fast port span
Fast Port Span is a system-wide parameter and is enabled by default. Therefore, all ports that are
eligible for Fast Port Span use it.
To disable or re-enable Fast Port Span, enter the following commands.
Brocade(config)#no fast port-span
Brocade(config)#write memory
Syntax: [no] fast port-span
NOTE
The fast port-span command has additional parameters that let you exclude specific ports. These
parameters are shown in the following section.
To re-enable Fast Port Span, enter the following commands.
Brocade(config)#fast port-span
Brocade(config)#write memory
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
