Quidway S6500 Series Ethernet Switches Chapter 1 MSTP Configuration Commands

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, please
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. Before BPDU PROTECTION is enabled on the switch,
the port received a BPDU runs as a non-edge port, even if it is configured as edge port.
For the related command, see stp edged-port.
Example
# Configure Ethernet2/0/3 as an edge port in system view.
[Quidway] stp interface Ethernet2/0/3 edged-port enable
1.1.17 stp interface loop-protection
Syntax
stp interface interface-list loop-protection
undo stp interface interface-list loop-protection
View
System view
Parameter
interface-list: Ethernet port list, containing multiple Ethernet ports and expressed as
interface _list = { { interface_type interface_num | interface_name } [ to { interface_type
interface_num | interface_name } ] }&<1-10>. For detail descriptions of interface_type,
interface_num and interface_name parameters, refer to the corresponding descriptions
in Port Command Manual. &<1-10> means that the preceding parameters can be
entered up to 10 times.
Description
Using stp interface loop-protection command, you can enable loop protection on the
switch in system view. Using undo stp interface loop-protection command, you can
restore the default loop protection state.
By default, loop protection is disabled.
For the related command, see stp loop-protection.
Example
# Enable loop protection on the Ethernet2/0/1.
