set protocols spanning-tree pvst vlan interface port-priority

The set protocols spanning-tree pvst vlan interface port-priority command configures the port priority of an interface in Rapid-PVST+ mode.

Command Syntax

set protocols spanning-tree pvst vlan <vlan-id> interface <interface-name> port-priority <port-priority>

Parameter

Parameter	Description
vlan <vlan-id>	Specifies the VLAN ID. The value is an integer that ranges from 1 to 4094.
interface <interface-name>	Specifies a port name. The value is a string that can be set to a physical port name or a LAG port.
port-priority <port-priority>	Specifies the priority value of a port. The value is an integer that ranges from 0 to 240. The default value is 128.

Usage Guidelines

In Rapid-PVST+ spanning tree calculation, the port path cost, bridge ID of the sending switch, and port priority determine whether the port can be selected as the designated port. A smaller priority value indicates higher probability of becoming the designated port, and a larger priority value indicates higher probability of becoming the blocking port.

On a network running Rapid-PVST+, a port can function as different roles in different spanning trees so that traffic from different VLANs is forwarded through different physical paths.

Example

Set the port priority of the switching device to 55 for VLAN 5.
