Chapter 4: Configuration Overview

Spanning Tree/Priority Write security: 2; Read security: 5

This assigns a priority to the Router Option Module 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 Router Option Module to test against the root device. The value is in one-tenth seconds with a range between 60 (6.0 seconds) 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 Protocol 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 mov- ing 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 spec- ified 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 traffic will be forwarded in or out. Setting to Yes (def) allows the port to participate in the spanning tree topology.

LAN Port/Path Cost

Write security: 2; Read security: 5

This is the cost of using the Ethernet port in the total cost of the path. The range is from 1 to 65535 with a default of 100 (for 10 Mbits/sec- ond).
