Configuring Errored Frame Seconds Event Detection

An errored frame seconds event occurs when the number of error frame seconds detected on a port
over a detection interval exceeds the error threshold.
Follow these steps to configure errored frame seconds event detection:
To do...
Enter system view
Configure the errored
frame seconds event
detection interval
Configure the errored
frame seconds event
triggering threshold
Make sure the errored frame seconds triggering threshold is less than the errored frame seconds
detection interval. Otherwise, no errored frame seconds event can be generated.

Enabling OAM Remote Loopback

After enabling OAM remote loopback on a port, you can send loopback frames from the port to a remote
port and then observe how many of these loopback frames are returned. In this way, you can calculate
the packet loss ratio on the link, thus evaluating the link performance.
