7.9 Loop Port Shutdown (Ethernet Port Attribute)

Description
The Loop Port Shutdown (Ethernet Port Attribute) parameter is set to disable the self-loop
port after a self-loop port is detected if the loop port shutdown function is enabled. After the
self-loop port is shut down, the self-loop port only transmits or receives the self-loop detection
packets rather than any other packets. If the port is not a self-loop port, it starts to work again.
Impact on the System
If a port enables the loop port shut-down function, the IEEE 802.3ah protocol blocks the port
once the port is detected to be a self-loop port. In this case, the services at the port are interrupted.
All the packets based on the upper-level protocol are discarded.

EFS8
Configuration Guidelines
To block a self-loop port, select Enabled. Otherwise, select Disabled.
Relationship with Other Parameters
The loop port shutdown function takes effect only after the IEEE 802.3ah protocol and the loop
detection function are enabled.
7.10 Traffic Threshold(Mbit/s)(External Ethernet Port
Attribute)
Description
The Traffic Threshold(Mbit/s) (External Ethernet Port Attribute) parameter specifies the
data flow threshold at external physical ports.
Impact on the System
If the data flow at external physical ports is greater than the specified threshold, the
FLOW_OVER alarm is generated.
