Command Manual – STP
Quidway S8500 Series Routing Switches
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 default state, i.e., non-edge
port.
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 the
configuration BPDUs from them.
Caution:
If the STP function has been enabled on the downstream equipment of the switch, do
not configure edge port on the equipment. Otherwise the system will fail to delete the
MAC address table entries and ARP address table entries on the port.
Related command: stp interface edged-port.
Example
# Configure Ethernet 2/1/1 as a non-edge port.
