9.4 spanning-tree timers
This command sets the spanning tree Timers and the no form of the command sets the spanning
tree timers to the default values.
spanning-tree {forward-time <seconds(4-30)> | hello-time <seconds(1-2)>
| maxage <seconds(6-40)>}
no spanning-tree { forward-time | hello-time | max-age }
Syntax Description
forward-time - Controls how fast a port changes its spanning tree state from Blocking state to
Forwarding state.
hello-time - Determines how often the switch broadcasts its hello message to other switches
when it is the root of the spanning tree.
max-age - The maximum age allowed for the Spanning Tree Protocol information learned from
the network on any port before it is discarded.
Mode
Global Configuration Mode
Defaults
max-age - 20 secs
forward-time - 15 secs
hello-time - 2 secs
Example
SMIS(config)#spanning-tree max-age 6
SMIS(config)#spanning-tree hello-time 1
SMIS(config)#spanning-tree forward-time 4
The following relation must be observed while configuring the timers:
2 x (Forward-time - 1) >= Max-age
Max-Age >= 2 x (Hello-time +1)
