Below is an example of N-Ring Status from an N-Ring Manager that had a faulted N-Ring, and just
achieved a healthy N-Ring:
In rare cases an N-Ring can have a “Partial Fault”. An example of this is to have a break in just one fiber in
a duplex channel fiber pair. The screenshot below shows N-Ring Manager Status when a ‘Higher’ N-Ring
Port (A2 or E2) is not receiving self health frames all the way around the N-Ring, though the other (low
A1/E1) N-Ring port is:
N-Ring Partial Fault (Error on high port)!!
