Configuring Spanning Tree Bridging Configuration Guide
To enable rapid STP, enter the following command in Configure mode:
Note This command is not supported with per-VLAN spanning tree.
5.6.2 Adjusting Spanning-Tree Parameters
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.
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.
Setting 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:
Enable rapid STP.
stp set protocol-version rstp
Set the bridge priority for default
spanning tree.
stp set bridging priority
<num>
Set the bridge priority for a particular
instance of spanning tree.
pvst set bridging spanning-tree
<string>
priority
<num>
