Command Parameters

enable

Enables BPDU Guard on the port. The default is disabled.

port {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]}

Identifies the slot and port in one of the following formats:

• a single slot and port (slot/port)

• a range of slots and ports (slot/port-slot/port)

• a series of slots and ports (slot/port,slot/port,slot/port)

• all ports on the same slot (slot/all)

• all ports on the switch (all)

If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

timeout <0-65535>

Specifies the value to use for port-state recovery. After a BPDU Guard disables a port, the port remains in the disabled state until this timer expires. You can configure a value from 10 to 65535. The default is 120 seconds.

Default

The default is disabled.
