Chapter 11 Configuring STP Configuring Spanning-Tree Features Configuring the Hello Time You can configure the interval between the generation of configuration messages by the root switch by changing the hello time. Note Exercise care when using this command. For most situations, we recommend that you use the spanning-tree vlan vlan-id root primary and the spanning-tree vlan vlan-id root secondary global configuration commands to modify the hello time. Beginning in privileged EXEC mode, follow these steps to configure the hello time of a VLAN: Step 1 Step 2 Command configure terminal spanning-tree vlan vlan-id hello-time seconds Step 3 Step 4 Step 5 end show spanning-tree vlan vlan-id copy running-config startup-config Purpose Enter global configuration mode. Configure the hello time of a VLAN. The hello time is the interval between the generation of configuration messages by the root switch. These messages mean that the switch is alive. • For vlan-id, the range is 1 to 4094 when the EI is installed and 1 to 1005 when the SI is installed. Do not enter leading zeros. • For seconds, the range is 1 to 10; the default is 2. Return to privileged EXEC mode. Verify your entries. (Optional) Save your entries in the configuration file. To return the switch to its default setting, use the no spanning-tree vlan vlan-id hello-time global configuration command. Configuring the Forwarding-Delay Time for a VLAN Beginning in privileged EXEC mode, follow these steps to configure the forwarding-delay time for a VLAN: Step 1 Step 2 Command configure terminal spanning-tree vlan vlan-id forward-time seconds Step 3 Step 4 Step 5 end show spanning-tree vlan vlan-id copy running-config startup-config Purpose Enter global configuration mode. Configure the forward time of a VLAN. The forward delay is the number of seconds a port waits before changing from its spanning-tree learning and listening states to the forwarding state. • For vlan-id, the range is 1 to 4094 when the EI is installed and 1 to 1005 when the SI is installed. Do not enter leading zeros. • For seconds, the range is 4 to 30; the default is 15. Return to privileged EXEC mode. Verify your entries. (Optional) Save your entries in the configuration file. 78-14982-01 Catalyst 2950 Desktop Switch Software Configuration Guide 11-19
