command.
Configuring the Hello Time
You can configure the interval between the generation of configuration messages by the root switch by
changing the hello time.

To return the switch to its default setting, use the no bridge bridge-group-number hello-time seconds
command.
Command Purpose
Step 1 Router# configure terminal Enters the global configuration mode.
Step 2 Router(config)# bridge
bridge-group-number priority
priority
Configures the switch priority of a bridge group.
For priority, the range is 0 to 61440 in increments of 4096; the
default is 32768. The lower the number, the more likely the switch
will be chosen as the root switch.
The value entered is rounded to the lower multiple of 4096. The
actual number is computed by adding this number to the bridge
group number.
Step 3 Router(config)# end Return to the privileged EXEC mode.
Command Purpose
Step 1 Router# configure terminal Enters global configuration mode.
Step 2 Router(config)# bridge
bridge-group-number hello-time
seconds
Configures the hello time of a bridge group. 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 seconds, the range is 1 to 10; the default is 2.
Step 3 Router(config)# end Returns to privileged EXEC mode.
