Step Command Remarks
2. Enter interface view or port
group view.
• Enter Ethernet interface view or Layer 2
aggregate interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual port-group-name
Use one of the commands.
3. Configure the maximum rate
of the ports.
stp transmit-limit limit The default setting is 10.
Configuring edge ports
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 network topology changes occur, an edge port will not cause
a temporary loop. Because a device does not determine whether a port is directly connected to a
terminal, you must manually configure the port as an edge port. After that, the port can transit rapidly
from the blocked state to the forwarding state.
Configuration restrictions and guidelines
• If BPDU guard is disabled, a port set as an edge port will become a non-edge port again if it
receives a BPDU from another port. To restore the edge port, re-enable it.
• If a port directly connects to a user terminal, configure it as an edge port and enable BPDU guard
for it. This enables the port to transit to the forwarding state quickly while ensuring network security.
• You cannot configure edge port settings and loop guard on a port at the same time.
Configuration procedure
To configure edge ports:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view or port
group view.
• Enter Ethernet interface view or Layer 2
aggregate interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual port-group-name
Use one of the commands.
3. Configure the current ports as
edge ports.
stp edged-port enable
All ports are non-edge ports
by default.
