Stp Edged-Port - H3C S7500E Series Command Manual

Command Manual – MSTP
H3C S7500E Series Ethernet Switches

1.1.20 stp edged-port

Syntax
stp edged-port { enable | disable }
undo stp edged-port
View
Ethernet interface view, port group view
Parameters
enable: Configures the current port to be an edge port.
disable: Configures the current port to be a non-edge port.
Description
Use the stp edged-port enable command to configure the port(s) to be an edge port or
edge ports.
Use the stp edged-port disable or undo stp edged-port enable command to
configure the port(s) to be a non-edge port or non-edge ports.
All Ethernet ports are non-edge ports by default.
Note that:
Configured in Ethernet interface view, the setting is effective on the current port
only; configured in port group view, the setting is effective on all ports in the port
group.
If a port directly connects to a user terminal rather than another device or a shared
LAN segment, this port is regarded as an edge port. When the network topology
changes, an edge port will not cause a temporary loop. Therefore, configuring a
port as an edge port can enable the port to transition to the forwarding state rapidly.
We recommend that you configure an Ethernet port directly connecting to a user
terminal as an edge port before to enable it to transition to the forwarding state
rapidly.
Normally, configuration BPDUs from other devices cannot reach an edge port
because it does not connect to any other device. Before the BPDU guard function
is enabled, if a port receives a configuration BPDU, the port is working actually as
a non-edge port even if you have configured it as an edge port.
Examples
# Configure GigabitEthernet 2/0/1 as a non-edge port.
