Configuring Edge Ports; Configuration Restrictions And Guidelines; Configuration Procedure - HP 6125G Configuration Manual

Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view .
3. Configure the maximum rate
of the ports.

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 change occurs, 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 transition 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 transition 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 specify a port as edge port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
3. Configure the current ports as
edge ports.
