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-role
Enables the root guard feature.
The default option is the root guard
feature disabled.
Step 4 end
Exits the configuration mode.
Step 5 show spanning-tree detail
Displays the spanning tree root 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-role” command resets the root guard feature to the
default value of disabled.
The example below shows how to enable the root guard feature.
Enable the root guard feature on ports cx 0/1 and cx 0/2
SMIS# configure terminal
SMIS(config)# interface range cx 0/1-2
SMIS(config-if)# spanning-tree restricted-role
SMIS(config-if)# end

Topology Change Guard
The topology change guard helps prevent unexpected topology changes. Network administrators can
configure the topology guard on ports that are not expected to receive topology change BPDUs.
Topology change BPDUs received on the topology change guard enabled ports will be dropped.
The topology guard feature is disabled on all ports by default.
Follow the steps below to enable the topology guard feature on the ports.
