Distributed Spanning Tree Commands

bridge slot/port mode

Configures Manual mode (forwarding or blocking) or Dynamic mode to manage the state of a port or an

aggregate of ports for the flat mode Common and Internal Spanning Tree (CIST) instance or a 1x1 mode

VLAN instance. Dynamic mode defers the configuration of the port state to the Spanning Tree Protocol.

bridge instance {slot/port | logical_port} mode {forwarding | blocking | dynamic}

Syntax Definitions

logical_port

By default, the port Spanning Tree mode is set to dynamic.

Platforms Supported

OmniSwitch 6250

Usage Guidelines

Specifying an instance number with this command when the switch is running the 1x1 Spanning Tree

operating mode implies a VLAN ID and configures the port Spanning Tree mode (forwarding, block-

ing, or dynamic) for the associated VLAN instance.

If the switch is running in the flat mode and STP (802.1D) or RSTP (802.1W) 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

Note that for Multiple Spanning Tree Instances (MSTI), the port Spanning Tree mode is inherited from

the CIST instance and is not a configurable parameter.

When port state is manually set to forwarding or blocking, the port remains in that state until it is

changed using this command.

Ports manually configured to operate in a forwarding or blocking state do not participate in the Span-

ning Tree Algorithm.

The CIST instance or an existing VLAN ID number (1–4094).

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).

Link aggregate ID number (0–31).

Set port state to forwarding.

Set port state to blocking.

Port state is determined by Spanning Tree Protocol.
