Set Spanning Tree Protocol Status
STP Priority
This value can determine if the IP-DSLAM will be root switch among all
known switches. The switch with the highest priority (lowest numeric value)
becomes the Spanning Tree root switch. MAC address (the lowest numeric
value) is used to decide root switch if priority is the same.
Valid values: 0 ~ 61440 in steps of 4096

becomes the Spanning Tree root switch. MAC address (the lowest numeric
value) is used to decide root switch if priority is the same.
Valid values: 0 ~ 61440 in steps of 4096
The time elapsed since the root node of the Spanning Tree has changed. The
change of the root node will cause the Spanning Tree to reconfigure.

Top Changed
The count which the root node has changed in the existing Spanning Tree.
Designated Root
The root of current Spanning Tree indicating by its MAC address.

Valid values: 1 ~ 30 (Seconds)
Bridge Forward Delay
This value, measured in units of seconds, controls how fast a port changes its
spanning state when moving towards the Forwarding state. The value
determines how long the port stays in each of the Listening and Learning states,
which precede the Forwarding state. This value is also used, when a topology
change has been detected and is underway, to age all dynamic entries in the
Forwarding Database.
Valid values: 4 ~ 30 (Seconds)

Forwarding Database.
