In order establish PVSTP, PVRSTP function, first of all, Root switch should be decided. 
Each switch has its own Bridge ID and Root switch on same LAN is decided by compar-
ing their Bridge ID. However, the user can change Root switch by configuring Priority for it. 
The switch having the lowest priority is decided as Root switch. 

To change Root switch by configuring Priority for it, use the following command. 

  VLAN-RANGE 

<0-61440> 

Configures a priority of switch. 

 

Bridge 

Clears a priority of switch. 

 

After deciding Root switch, you need to decide to which route you will forward the packet. 
To do this, the standard is path-cost. Generally, path-cost depends on transmission speed 
of LAN interface in switch. In case the route is overload based on Path-cost, it is better to 
take another route.   

By considering the situation, the user can configure Path-cost of Root port in order to des-
ignate the route on ones own. To configure Path-cost, use the following command. 

 VLAN-RANGE PORTS 

<1-200000000> 

Configures path-cost to configure route 
on user’s own. 

 VLAN-RANGE PORTS 

Bridge 

Clears path-cost configuration. 

 

When all conditions of two switches are same, the last standard to decide route is port-
priority. It is also possible to configure port priority so that user can configure route manu-
ally. To configure port priority, use the following command. 

 

 PORTS <0-240> 

Configures port-priority. 

 

 PORTS 

Bridge 

Disables port priority configuration.
