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

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

Interface configuration mode

Modes

 

 

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 Note the following details about edge ports and their behavior:

Guidelines

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
