Remove/Alarm
- This is the highest level of ring security. In this security mode,
the ring is locked to new stations. The Remove/Alarm mode sends a ÒRemove
MAC FrameÓ command to a new station attempting to enter the ring, and a
trap/alarm to the NMS informing it of the action taken. If, after three attempts,
the station cannot be removed from the ring, remove alarm sends a trap/alarm
ÒRemove FailureÓ to the NMS, informing it that the station could not be
removed.
