Spanning Tree/Priority

Write security: 2; Read security: 5

This assigns a priority to the Express XL/XLT that permits the relative priority of multiple bridges to be managed. The range is 0 to 65535 with a default of 32768.

Spanning Tree/Maximum Age

Write security: 2; Read security: 5

This is the timeout value used by the Express XL/XLT to test against the root device. The value is in one-tenth seconds with a range between 60 (6.0 sec- onds) and 400 (40.0 seconds). The default is 200 (20.0 seconds).

Spanning Tree/Hello Time

Write security: 2; Read security: 5

This is the time between the generation of configuration BPDUs (Bridging Pro- tocol Data Units) by the root bridge. The value is in one-tenth seconds with a range between 10 (1.0 second) and 100 (10.0 seconds). The default is 20 (2.0 seconds).

Spanning Tree/Forward Delay

Write security: 2; Read security: 5

This is the time spent in the listening and learning state while moving from the blocking state to the forwarding state. The value is in one-tenth seconds with a range between 40 (4.0 seconds) and 300 (30.0 seconds). The default is 150 (15.0 seconds).

Spanning Tree/LAN Port

The path cost and priority parameters for the Ethernet port are specified under this menu.

LAN Port/Active

Write security: 2; Read security: 5

The Ethernet port can be disabled when set to No. In this mode, no bridge traf- fic will be forwarded in or out. Setting to Yes (def) allows the port to partici- pate in the spanning tree topology.
