protocol data units (BPDUs) with other STP-enabled devices, the device with the lowest

priority value becomes the root bridge.

•

Bridge Max Age

. Specifies the maximum age of the current bridge in seconds. This is the

maximum age of the STP information that is learned from the network before it is

discarded.

•

Bridge Hello Time

Specifies the period in seconds that the switch waits before sending

configuration PDUs when it is the root of the spanning tree or trying to become the root.

•

Bridge Forward Delay

Indicates the period in seconds that the port stays in each of the

listening and learning states that precedes the forward state. This period is also used to age

all dynamic entries in the forwarding databases when a topology change has been detected

and is underway.

Advanced—Port Configuration

The Port Configuration screen, also referred to as the Rapid Spanning Tree Port Configuration

screen, lets you view and modify the RSTP settings:

Select Switching > STP > Advanced > Port Configuration. A screen similar to the following

displays.
