Configuring Spanning Tree STP/RSTP Configurations
The following example shows how to enable spanning tree function on port 1/0/3 and
configure the port priority as 32 :
Switch#configure
Switch(config)#interface gigabitEthernet 1/0/3
Switch(config-if)#spanning-tree
Switch(config-if)#spanning-tree common-config port-priority 32
Switch(config-if)#show spanning-tree interface gigabitEthernet 1/0/3
Interface State Prio Ext-Cost Int-Cost Edge P2p Mode
---------- ------- ---- ------ -------- ---- --------- -----
Gi1/0/3 Enable 32 Auto Auto No No(auto) N/A
Role Status LAG
----- ------- ------
N/A LnkDwn N/A
Switch(config-if)#end
Switch#copy running-config startup-config
2.2.2 Configuring Global STP/RSTP Parameters
Follow these steps to configure global STP/RSTP parameters of the switch:
Step 1 configure
Enter global configuration mode.
Step 2 spanning-tree priority
pri
Configure the priority of the switch.
pri :
Specify the priority for the switch. The valid value is from 0 to 61440, which are divisible
by 4096. The priority is a parameter used to determine the root bridge for spanning tree. The
switch with the lower value has the higher priority.
In STP/RSTP, the value is the priority of the switch in spanning tree. The switch with the highest
priority will be elected as the root bridge.
In MSTP, the value is the priority of the switch in CIST. The switch with the higher priority will be
elected as the root bridge in CIST.
