spanning-tree edgeport

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.

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.
• A port must become an edge port before it receives a BPDU.
• 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
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
switch(conf-if-te-0/1)#spanning-tree edgeport bpdu-guard
