Parameters
enable
: Configures the current Ethernet port as an edge port.
disable
: Configures the current Ethernet port as a non-edge port.
Description
Use the
stp edged-port enable
command to configure the current Ethernet port as an
edge port.
Use the
stp edged-port disable
command to configure the current Ethernet port as a
non-edge port.
Use the
undo stp edged-port
command to restore the current Ethernet port to its
default state.
By default, all Ethernet ports of a switch are non-edge ports.
An edge port is a port that is directly connected to a user terminal instead of another
switch or shared network segment. Rapid transition to the forwarding state is applied to
edge ports because on these ports no loops can be incurred by network topology
changes. You can enable a port to turn to the forwarding state rapidly by setting it to an
edge port. And you are recommended to configure the Ethernet ports directly
connected to user terminals as edge ports to enable them to turn to the forwarding state
rapidly.
Normally, configuration BPDUs cannot reach an edge port because the port is not
connected to another switch. But when the BPDU guard function is disabled on an
edge port, configuration BPDUs sent deliberately by a malicious user may reach the
port. If an edge port receives a BPDU, it turns to a non-edge port.
