ADC MM701G2, MM702G2 user manual Spanning Tree, Priority, Hello Time, Forward Delay, Max Age

April 14, 2006 Chapter 5: Configuring System Parameters

The default spanning tree setting is disabled. Access spanning tree configuration as follows:

Step	Action
1	Select System on the menu bar, then select Spanning Tree under Configuration to access the Bridge
	Spanning Tree page (Figure 5-11).
	Figure 5-11. Spanning Tree Configuration
2	Enter the following parameters to enable STP for bridging sessions:
	– Spanning Tree
	Select Enable to activate the STP for all RFC 1483-Bridge sessions and LAN Port. Disable turns off
	STP for all modem bridging sessions and LAN Port.
	– Priority
	The modem STP priority (how centrally located this bridge is) in the network. A lower number
	indicates a more centrally located bridge. The valid priority range is 0 to 65535. A priority of 32768 is
	the default value.
	– Hello Time
	The time interval in seconds at which the modem should send STP packets. Default value is 2
	seconds.
	– Forward Delay
	The time interval in seconds that should be waited until the state of an interface can change. This
	delay prevents interface states from changing so rapidly that STP cannot keep up with the current
	network topology and therefore cannot efficiently managing bridging. Default value is 15 seconds.
	– Max Age
	The time interval in seconds after which Spanning Tree entries that are not relearned are deleted
	from the bridging table. Default value is 20 seconds.
