Configuring Spanning-Tree Features
Beginning in privileged EXEC mode, follow these steps to configure the port priority of a spanning-tree
port. This procedure is optional.
Command
Step 1 configure terminal
Step 2
interface interface-id
Step 3
spanning-tree port-priority priority
Step 4 spanning-tree vlan vlan-id port-priority priority
Step 5 end
Step 6
show spanning-tree interface interface-id
or
show spanning-tree vlan vlan-id
Step 7 copy running-config startup-config
The show spanning-tree interface interface-id privileged EXEC command displays information only
Note
if the port is in a link-up operative state. Otherwise, you can use the show running-config interface
privileged EXEC command to confirm the configuration.

Purpose
Enter global configuration mode.
Specify an interface to configure, and enter interface
configuration mode.
If a physical interface is a UNI, before attempting
Note
to configure it as a spanning-tree link, you must
enter the port-type nni interface configuration
command or configure the port as an ENI and
enable spanning tree on the port. See
Spanning Tree on an ENI" section on page
If the interface is a VLAN, only ports with
spanning tree enabled in the VLAN will run
spanning tree.
If the interface is a port channel, all members of the
port channel must be NNIs or ENIs with spanning
tree enabled.
Configure the port priority for the spanning-tree port.
For priority, the range is 0 to 240, in increments of 16; the
default is 128. Valid values are 0, 16, 32, 48, 64, 80, 96,
112, 128, 144, 160, 176, 192, 208, 224, and 240. All other
values are rejected. The lower the number, the higher the
priority.
Configure the port priority for a VLAN.
For vlan-id, you can specify a single VLAN identified
•
by VLAN ID number, a range of VLANs separated by
a hyphen, or a series of VLANs separated by a comma.
The range is 1 to 4094.
For priority, the range is 0 to 240, in increments of 16;
•
the default is 128. Valid values are 0, 16, 32, 48, 64, 80,
96, 112, 128, 144, 160, 176, 192, 208, 224, and 240.
All other values are rejected. The lower the number,
the higher the priority.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
