Configuring STP
Beginning in privileged EXEC mode, follow these steps to configure the port priority of an interface.
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.
To return to the default setting, use the no spanning-tree [vlan vlan-id] port-priority interface
configuration command. For information on how to configure load sharing on trunk ports by using
spanning-tree port priorities, see the
OL-13018-01
Purpose
Enter global configuration mode.
Specify an interface to configure, and enter interface
configuration mode.
Valid interfaces include physical ports and port-channel
logical interfaces (port-channel port-channel-number).
Configure the port priority for an interface.
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.
