Changing the STP port priority
To change the priority of a port, use one of the following commands:
set spantree portpri port-list priority value
set spantree portvlanpri port-list priority 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:
WSS# 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:
WSS# set spantree portvlanpri 3-4 priority 48 vlan mauve
success: change accepted.
Resetting the STP port priority to the default value
To reset the STP port priority to the default value, use one of the following commands:
clear spantree portpri port-list
clear spantree portvlanpri port-list {all | vlan vlan-id}
The command applies only to the ports you specify. The port cost on other ports remains unchanged.
