STP configuration for VLANs.

Posted on 2004-09-18

When you configure the STP protocol in your switch, are you configuring it for all VLANs simultaenously or just the default VLAN 1?

I asked this question because I saw this:

2924(config)#spanning-tree ?
  forward-time  Set a Spanning Tree FORWARD Interval
  hello-time    Set a Spanning Tree HELLO Interval
  max-age       Set a Spanning Tree MAX AGE Interval
  portfast      Allow a change from blocking to forwarding
  priority      Set a Spanning Tree Priority
  protocol      Spanning tree protocol type
  uplinkfast    Enable UplinkFast Feature
  vlan          VLAN Switch Spanning Trees   <-------------Saw this


Thanks guys

As long as you are in global config, you are making global changes.
If you go into vlan, then the changes are specific to the vlan.

C3550(config)#spanning-tree vlan ?
  WORD  vlan range, example: 1,3-5,7,9-11

C3550(config)#spanning-tree vlan 2 ?
  forward-time  Set the forward delay for the spanning tree
  hello-time    Set the hello interval for the spanning tree
  max-age       Set the max age interval for the spanning tree
  priority      Set the bridge priority for the spanning tree
  root          Configure switch as root
