Distributed Spanning Tree Commands
OmniSwitch 6250 CLI Reference Guide November 2009 page 16-59
bridge slot/port priority
Configures the Spanning Tree priority for a single port or an aggregate of ports for the flat mode Common
and Internal Spanning Tree (CIST) instance or a 1x1 mode VLAN instance. The Spanning Tree Algo-
rithm uses the port priority value to determine the most favorable port when a bridge has multiple ports
with the same path cost to the root bridge.
bridge instance {slot/port | logical_port} priority priority
Syntax Definitions
instance The flat mode CIST instance or an existing VLAN ID number (1–4094).
slot/port Enter the slot number for the module and the physical port number on
that module (e.g., 3/1 specifies port 1 on slot 3).
logical_port Link aggregate ID number (0–31).
priority Port priority value (0–15). The lower the number, the higher the
priority.
Defaults
By default, the bridge port priority value is set to 7.
Platforms Supported
OmniSwitch 6250
Usage Guidelines
•
The port priority specifies the value of the priority field contained in the first byte of the Port ID. The
second byte contains the physical switch port number.
•
Specifying an instance number with this command when the switch is running in the 1x1 Spanning
Tree mode implies a VLAN ID and configures the port priority value for the associated VLAN
instance.
•
If the switch is running in the flat mode and STP or RSTP is the active protocol, enter 1 to specify the
CIST instance. If MSTP is the active protocol, however, entering 1 for the instance number is not
accepted. In this case, use the
bridge cist slot/port priority command instead.
Examples
-> bridge mode flat
-> bridge 1 4/1 priority 0
-> bridge mode 1x1
-> bridge 255 1/24 priority 5
-> bridge 455 3/12 priority 15
