Chapter 6 Configuring STP and RSTP on the ML-Series Card
Configuring STP and RSTP Features
Beginning in privileged EXEC mode, follow these steps to configure the switch priority of a bridge
group:
To return the switch to its default setting, use the no bridge bridge-group-number priority
priority-number command.
Configuring the Hello Time
Change the hello time to configure the interval between the generation of configuration messages by the
root switch.
Beginning in privileged EXEC mode, follow these steps to configure the hello time of a bridge group:
To return the switch to its default setting, use the no bridge bridge-group-number hello-time seconds
command. The number for seconds should be the same number as configured in the original command.
Command Purpose
Step 1
ML_Series# configure terminal
Enters the global configuration mode.
Step 2
ML_Series(config)# bridge
bridge-group-number
priority
priority-number
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
ML_Series(config)# end
Return to the privileged EXEC mode.
Command Purpose
Step 1
ML_Series# configure terminal
Enters global configuration mode.
Step 2
ML_Series(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
ML_Series(config)# end
Returns to privileged EXEC mode.
