9T122-08 Module Speciﬁc Information

¥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.

NOTE

If you change directly from Disabled mode to Remove/Alarm mode, all stations that have not been added to the allowed list will be removed from the token ring.
