Adjust Spanning-Tree Parameters

Chapter 2: Bridging Configuration Guide

Note: If you are running spanning tree on one or more VLANs, you must enable spanning tree on all ports belonging to each VLAN.

Enable spanning tree on one or more ports.

stp enable port <port-list>

You may need to adjust certain spanning-tree parameters if the default values are not suitable for your bridge configuration. Parameters affecting the entire spanning tree are configured with variations of the bridge global configuration command. Interface-specific parameters are configured with variations of the bridge-group interface configuration command.

You can adjust spanning-tree parameters by performing any of the tasks in the following sections:

•Set the Bridge Priority

•Set an Interface Priority

Note: Only network administrators with a good understanding of how bridges and the

Spanning-Tree Protocol work should make adjustments to spanning-tree parameters. Poorly chosen adjustments to these parameters can have a negative impact on performance. A good source on bridging is the IEEE 802.1d specification.

Set the Bridge Priority

You can globally configure the priority of an individual bridge when two bridges tie for position as the root bridge, or you can configure the likelihood that a bridge will be selected as the root bridge. The lower the bridge's priority, the more likely the bridge will be selected as the root bridge. This priority is determined by default; however, you can change it.

To set the bridge priority, enter the following command in Configure mode:

Set the bridge priority.

stp set bridging priority <num>

Set a Port Priority

You can set a priority for an interface. When two bridges tie for position as the root bridge, you configure an interface priority to break the tie. The bridge with the lowest interface value is elected.
