The topology openRing trap indicates that the RPR ring is opened.

The exceeded max reserved rate trap indicates that the rate
on the ringlet exceeded the max reserved rate. The operator can
configure reserved rate for every station, but the sum of all
stations' reserved rate of each RPR ringlet can't exceed maximum.

The exceeded max station number trap indicates that the number
of the stations on the ring exceeded the max station number.

The miscabling trap indicates that the miscabling event occurred.

The back pressure trap indicates that the backpressure is generated
on the ringlet. That is the data flow on the ringlet exceeded
the range of rate-limit configured.

The back pressure over trap indicates that the backpressure is
disappeared on the ringlet.

The topology openRing trap indicates that the RPR ring is closed.

The topology inconsistent trap indicates that the topology of
RPR is inconsistent.

The topology instability trap indicates that the topology of
RPR is instability.

The duplicate MAC address trap indicates that the mac address
of the station on the ring is dulplicate. That means there is the
same MAC address between two stations on the ring.

The dulplicate IP address trap indicates that the IP address of
the station on the ring is dulplicate. That means there is the same
IP address between two stations on the ring.

The incomplete LRTT trap indicates that LRTT is not completed.

The protection configuration inconsistent trap indicates that
the configuration of protection mode on the ring is inconsistent.
That is one station is configured steer mode while the other is
configured wrap mode.

The jumbo configuration inconsistent trap indicates that the
configuration of jumbo mode on the ring is inconsistent.
That is one station supports jumbo frame while the other
doesn't support jumbo frame.
