STP Bridge
Parameters
You can enable or disable Spanning Tree Protocol in the system and set the
following STP bridge parameters: priority, maximum age, hello time, and
forward delay. For more information about how the Spanning Tree
parameters interact at the bridge level to create a loopless network, see
Chapter 5: Transparent Bridging in the SuperStack™ II Switch 2200 Operation
Guide.
Enabling and
Disabling STP on a
Bridge
When Spanning Tree Protocol is disabled, the bridge does not participate in
the Spanning Tree algorithm.
The default value is disabled.
To enable or disable Spanning Tree Protocol:
1 From the top level of the Administration Console, enter:
bridge stpState
2 Enter enabled or disabled at the prompt.
Setting the
Bridge Priority
The bridge priority influences the choice of the root bridge and the
designated bridge. The lower the bridge’s priority number, the more likely
that the bridge will be chosen as the root bridge or a designated bridge.
Bridge priority values The bridge priority value is appended as the most significant portion of a
bridge identifier (for example:
8000 00803e003dc0). It is a 2-octet value.
