Chapter 2: Bridging Configuration Guide
SSR User Reference Manual 2 - 7
To enable a port to flow-based bridging, enter the following command in Configure
Mode.
To change a port from flow-based bridging to address-based bridging, enter the
following command in Configure mode:
Configuring Spanning Tree
The SSR supports only one spanning tree process per SSR. By default, spanning tree
is disabled on the SSR. To enable spanning tree on the SSR, you perform the following
task on the ports where you want spanning tree enabled.
Note: If you are running spanning tree on one or more VLANs, you must enable
spanning tree on all ports belonging to each VLAN.
Adjust 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.
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.
