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 Step 2 configure Enter global configuration mode. 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. User Guide 312
