Distributed Spanning Tree Commands

bridge 1x1 slot/port restricted-role

Configures whether or not to prevent a port (or an aggregate of ports) for the specified 1x1 mode VLAN

instance from becoming the root port. When this parameter is enabled, the port will not become the root

even if the port is the most likely candidate for the root. Once another port is selected as the root port, the

restricted port becomes the Alternate Port.

bridge 1x1 vid {slot/port | logical_port} {restricted-role | root-guard} {on | off | enable | disable}

Syntax Definitions

logical_port

By default, the port is not restricted from becoming the root port.

Platforms Supported

OmniSwitch 6250

Usage Guidelines

Note that preventing an eligible port from becoming the root may impact connectivity within the

Network administrators exclude certain ports from becoming the root to prevent bridges external to the

core region of the network from influencing the Spanning Tree topology.

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

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

If the switch is running in the flat mode when this command is used, the restricted status of the port is

not active for the VLAN instance until the switch is running in the 1x1 Spanning Tree mode.

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

in their explicit format.
