Cisco IE 3000 Switch Command Reference

Chapter 2 IE 3000 Switch Cisco IOS Commands
spanning-tree port-priority
spanning-tree port-priority
Use the spanning-tree port-priority interface configuration command to configure an interface
priority. If a loop occurs, spanning tree can find the interface to put in the forwarding state. Use the no
form of this command to return to the default setting.
spanning-tree [vlan vlan-id] port-priority priority
no spanning-tree [vlan vlan-id] port-priority
Syntax Description
Defaults The default is 128.
Command Modes Interface configuration
Command History
Usage Guidelines If the variable vlan-id is omitted, the command applies to the spanning-tree instance associated with
VLAN 1.
You can set the priority on a VLAN that has no interfaces assigned to it. The setting takes effect when
you assign the interface to the VLAN.
If you configure an interface with both the spanning-tree vlan vlan-id port-priority priority command
and the spanning-tree port-priority priority command, the spanning-tree vlan vlan-id port-priority
priority command takes effect.
Examples This example shows how to increase the likelihood that a port will be put in the forwarding state if a loop
occurs:
Switch(config)# interface gigabitethernet1/2
Switch(config-if)# spanning-tree vlan 20 port-priority 0
This example shows how to set the port-priority value on VLANs 20 to 25:
Switch(config-if)# spanning-tree vlan 20-25 port-priority 0
You can verify your settings by entering the show spanning-tree interface interface-id privileged
EXEC command.
vlan vlan-id (Optional) VLAN range associated with a spanning-tree instance. 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.
priority Number from 0 to 240, in increments of 16. 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.
