Changing the STP Port Priority

To change the priority of a port, use one of the following commands:

set spantree portpri port-listpriority value

set spantree portvlanpri port-listpriority value {all vlan vlan-id}

The set spantree portpri command changes the priority for ports in the default VLAN (VLAN 1) only. The set spantree portvlanpri command changes the priority for ports in a specific other VLAN or in all VLANs.

Specify a priority from 0 (highest priority) through 255 (lowest priority). The default is 128.

The all option applies the change to all VLANs. Alternatively, specify an individual VLAN.

To set the priority of ports 3 and 4 in the default VLAN to 48, type the following command:

WX1200# set spantree portpri 3-4 priority 48 success: change accepted.

To set the priority of ports 3 and 4 to 48 in VLAN mauve, type the following command:

WX1200# set spantree portvlanpri 3-4 priority 48 vlan mauve success: change accepted.
