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.
