Verifying and Monitoring STP and RSTP Status

Configuring the Forwarding-Delay Time for a Bridge Group

Beginning in privileged EXEC mode, follow these steps to configure the forwarding-delay time for a bridge group:

	Command	Purpose
Step 1
	ML_Series# configure	Enters global configuration mode.
	terminal
Step 2
	ML_Series(config)# bridge	Configures the forward time of a VLAN. The forward delay is the
	bridge-group-number	number of seconds a port waits before changing from its
	forward-time seconds	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.

To return the switch to its default setting, use the no bridge bridge-group-numberforward-timeseconds 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:

	Command	Purpose
Step 1
	ML_Series# configure	Enters global configuration mode.
	terminal
Step 2
	ML_Series(config)# bridge	Configures the maximum-aging time of a bridge group. The
	bridge-group-number max-age	maximum-aging time is the number of seconds a switch waits
	seconds	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	Returns to privileged EXEC mode.

To return the switch to its default setting, use the no bridge bridge-group-numbermax-ageseconds command. The number for seconds should be the same number as configured in the original command.

Verifying and Monitoring STP and RSTP Status

To display the STP or RSTP status, use one or more of the privileged EXEC commands in Table 7-6.
