bridge group:
To return the switch to its default setting, use the no bridge bridge-group-number forward-time seconds
command. The number for seconds should be the same number as configured in the original command.
Configuring the Maximum-Aging Time for a Bridge Group
Beginning in privileged EXEC mode, follow these steps to configure the maximum-aging time for a
bridge group:
To return the switch to its default setting, use the no bridge bridge-group-number max-age seconds

Command Purpose
Step 1
ML_Series# configure
terminal
Enters global configuration mode.
Step 2
ML_Series(config)# bridge
bridge-group-number
forward-time
seconds

number of seconds a port waits before changing from its
spanning-tree learning and listening states to the forwarding state.
For seconds, the range is 4 to 200; the default is 15.
Step 3
ML_Series(config)# end
Returns to privileged EXEC mode.
Command Purpose
Step 1
ML_Series# configure
terminal
Enters global configuration mode.
Step 2
ML_Series(config)# bridge
bridge-group-number
max-age
seconds
Configures the maximum-aging time of a bridge group. The
maximum-aging time is the number of seconds a switch waits
without receiving spanning-tree configuration messages before
attempting a reconfiguration.
For seconds, the range is 6 to 200; the default is 20.
Step 3
ML_Series(config)# end
