spanning-tree edgeport

9

spanning-tree edgeport

Enables the edge port on an interface to allow the interface to quickly transition to the forwarding 
state.

Synopsis

spanning-tree edgeport [bpdu-filter | bpdu-guard]

Operands

bpdu-filter

Sets the edge port Bridge Protocol Data Unit (BPDU) filter for the port.

bpdu-guard

Guards the port against the reception of BPDUs.

Defaults

Edge port is disabled.

Command

Modes

Interface configuration mode

Description

Use this command to enable the edge port feature. This command is only for RSTP and MSTP. Use 
the spanning-tree portfast command for STP.

Usage

Guidelines

Note the following details about edge ports and their behavior:

•

A port can become an edge port if no BPDU is received.

•

When an edge port receives a BPDU, it becomes a normal spanning-tree port and is no longer 
an edge port.

•

Because ports directly connected to end stations cannot create bridging loops in the network, 
edge ports directly transition to the forwarding state, and skip the listening and learning states

Examples

To enable a port to quickly transition to the forwarding state:

switch(conf-if-te-0/1)#spanning-tree edgeport 

To set the edgeport BPDU filter for the port:

switch(conf-if-te-0/1)#spanning-tree edgeport bpdu-filter

To guard the port against reception of BPDUs:

switch(conf-if-te-0/1)#spanning-tree edgeport bpdu-guard
