Step 1
configure terminal
Enters the configuration mode
Step 2
interface <interface-type><interface-id>
or
interface range <interface-type><interface-id> ….
Enters the port interface mode.
interface-type – may be any of the
following:
fx-ethernet – fx
cx-ethernet – cx
port-channel – po
interface-id is in slot/port format for all
physical interfaces. It may be the port
channel identifier for port channel
interfaces.
To configure multiple interfaces, use
the “interface range …” command. To
provide a range use a hypen (-)
between the start and end interface
numbers.
E.g.: int range fx 0/1-10
To provide multiple interfaces or
ranges, use separate with a comma (,).
E.g.: int range fx 0/1-10, fx 0/20
Step 3
spanning-tree restricted-tcn
Enables the topology guard feature.
The default option is the topology
guard feature disabled.
Step 4
end
Exits the configuration mode.
Step 5
show spanning-tree detail
Displays the spanning tree topology
guard information.
Step 6
write startup-config
Optional step – saves this spanning tree
configuration to be part of startup
configuration.
The “no spanning-tree restricted-tcn” command resets the topology guard feature to the
default value of disabled.
The example below shows how to enable the topology guard feature.
Enable the topology guard feature on ports cx 0/1 and cx 0/2
SMIS# configure terminal
SMIS(config)# interface range cx 0/1-2
