MSTP Configuration Commands 187
Parameter
interface-list: Ethernet port list, containing multiple Ethernet ports and expressed
as interface-list = { interface-type interface-number [ to interface-type
interface-number ] }&<1-10>. For detail descriptions of interface-type and
interface-number parameters, refer to the corresponding descriptions in Port
Command Manual. &<1-10> means that the preceding parameters can be
entered up to 10 times.
enable: Configures the current port as an edge port.
disable: Configures the current port as a non-edge port.
Description
Use the stp interface edged-port enable command to configure a port as an
edge port in system view.
Use the stp interface edged-port disable command to configure a port as a
non-edge port in system view.
Use the undo stp interface edged-port command to restore the port to the
default type (that is, non-edge port) in system view.
By default, all the switch ports are configured as non-edge ports.
If the current Ethernet port is connected to other switches, you can use the stp
interface edged-port disable or undo stp interface edged-port command to
configure it as a non-edge port. The stp interface 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
the configuration BPDUs from them.
Related command: stp edged-port.
