Syntax
stp edged-port { enable | disable }
undo stp edged-port
View
Ethernet port view
Parameter
enable: Configures the current port as an edge port.
disable: Configures the current 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 undo stp edged-port command to restore the default state, i.e.,

By default, all the switch ports are configured as non-edge ports.
If the current Ethernet port is connected to other switch, you can use the stp
edged-port disable or no stp edged-port command to configure it as a non-edge
port. The stp edged-port enable command is used for configuring the port as an
edge port.

A port is considered as an edge port when it is directly connected to the user
terminal, instead of any other switches or shared network segments. The edge
port will not cause loop upon network topology changes. Accordingly, you can
configure a port as an edge port, so that it can transit to forwarding state fast. For
this purpose, configure the Ethernet port directly connected to the user terminal
as an edge port.

Because the edge port is not connected to any other switches, it will not receive

CAUTION: If the STP function has been enabled on the downstream equipment of

will fail to delete the MAC address table entries and ARP address table entries on
the port.
