Configuring Spanning Tree STP/RSTP Configurations Step 3 Step 4 Step 5 Step 6 Step 7 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. spanning-tree hold-count value 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. show spanning-tree bridge (Optional) View the global STP/RSTP parameters of the switch. end Return to privileged EXEC mode. copy running-config startup-config Save the settings in the configuration file. Note: To prevent frequent network flapping, make sure that Hello Time, Forward Delay, and Max Age conform to the following formulas: •• 2*(Hello Time + 1) = Max Age This example shows how to configure the priority of the switch as 36864, the Forward Delay as 12 seconds: User Guide 315
