Configuring Spanning Tree MSTP Configurations Interface Prio Cost Role Status LAG Gi1/0/3 144 200 N/A LnkDwn N/A Switch(config-if)#end Switch#copy running-config startup-config 3.2.3 Configuring Global MSTP Parameters Follow these steps to configure the global MSTP parameters of the switch: Step 1 configure Enter global configuration mode. Step 2 spanning-tree priority pri Configure the priority of the switch for comparison in CIST. 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. Step 3 spanning-tree timer {[ forward-time forward-time ] [ hello-time hello-time ] [ max-age maxage ]} (Optional) Configure the Forward Delay, Hello Time and Max Age. forward-time: Specify the value of Forward Delay. It is the interval between the port state transition from listening to learning. The valid values are from 4 to 30 in seconds, and the default value is 15. Forward Delay is used to prevent the network from causing temporary loops during the regeneration of spanning tree. The interval between the port state transition from learning to forwarding is also the Forward Delay. hello-time: Specify the value of Hello Time. It is the interval between BPDUs' sending. The valid values are from 1 to 10 in seconds, and the default value is 2. The root bridge sends configuration BPDUs at an interval of Hello Time. It works with the MAX Age to test the link failures and maintain the spanning tree. max-age: Specify the value of Max Age. It is the maximum time that the switch can wait without receiving a BPDU before attempting to regenerate a new spanning tree. The valid values are from 6 to 40 in seconds, and the default value is 20. Step 4 spanning-tree hold-count value (Optional) Specify the maximum number of BPDU that can be sent in a second. value: Specify the maximum number of BPDU packets that can be sent in a second. The valid values are from 1 to 20 pps, and the default value is 5. User Guide 332
