4.10.2 Viewing and Configuring Bridge Instance Details

The Bride Instance tab displays the number of MST instance created and VLANS associated with it. To view
and configure the MSTP bridge instance:
1. Select Network
2. Select the Bridge Instance
The Bridge Instance tab displays the following:
ID
Bridge Priority
Bridge ID
Designated Root
Displays the configured forward delay period.
Enter the CIST bridge maximum age received from the root bridge. If this is the root
bridge, the value will be equal to the Configured Max Age.
The max-age is the maximum time (in seconds) for which (if a bridge is the root
bridge) a message is considered valid. This prevents the frames from looping
indefinitely. The max-age should be greater than twice the value of hello time plus
one, but less than twice the value of forward delay minus one. The allowable range
for max-age is 6-40 seconds. Configure this value sufficiently high, so a frame
generated by root can be propagated to the leaf nodes without exceeding the max-
age.

Displays the ID of the MST instance.
Displays the bridge priority for the associated instance.
The Bridge Priority is assigned to an individual bridge based on whether it is
selected as the root bridge. The lower the priority, the greater likelihood the bridge
becoming the root.
Displays the MAC address of the bridge.
Displays the ID of the root bridge that sent the BPDU received on this port.
