Note
Dependencies when setting the timing
If you specify the time settings for spanning tree, you need to keep to the following two rules:
● 2 * (forward-time - 1) ≥ max-age
● max-age ≥ 2 * (hello-time + 1)
Result
The selected setting for the time is configured.
Further notes
You reset the time settings to the default values with the no spanning-tree forward-
time, no spanning-tree hello-time or no spanning-tree max-age.
If you call the no spanning-tree command without parameters, you disable the spanning
tree function. The configured time settings are retained.
If you call the restart factory command, the system restarts with the factory configuration
settings All rime settings are reset.
You display these settings and other information with the commands that start with show
