Distributed Spanning Tree Commands

bridge 1x1 slot/port priority

Configures the Spanning Tree priority value for a port or an aggregate of ports for the specified 1x1 mode

VLAN instance. The Spanning Tree algorithm uses the port priority value to determine the most favor-

able port when a bridge has multiple ports with the same path cost to the root bridge.

bridge 1x1 vid {slot/port | logical_port} priority priority

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.

This command is an explicit Spanning Tree command that only applies to the specified VLAN instance

regardless of which operating mode (flat or 1x1) or protocol is active on the switch.

If the switch is running in the flat mode when this command is used, the specified priority value for the

port is not active for the specified VLAN instance until the operating mode for the switch is changed to

the 1x1 mode.

Note that when a configuration snapshot is taken of the switch, all Spanning Tree commands are saved

in their explicit format.
