Matt:

Yes, on the root switch, if you want the values to rule the STP domain.

SW2(config)#spanning-tree vlan 1 ?
  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
  <cr>

SW2#sh spanning-tree

VLAN0001
  Spanning tree enabled protocol ieee
  Root ID Priority 32769
             Address 000b.be84.3400
             Cost 12
             Port 65 (Port-channel1)
             Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec <--
These values rule

  Bridge ID Priority 32769 (priority 32768 sys-id-ext 1)
             Address 0013.8048.fcc0
             Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec <--
Local values
             Aging Time 600

Hi Group,

I am trying to understand the configurations/changing of STP timers ( such
as"spanning-tree vlan vlan-id hello-time")?.

Can someone tell me where we should configure these configs?
I mean on a practice lab with 2 CAT3550, do we need to configure it on root
bridge only?

Thanks

Mathew
