Only stations on the ring’s allowed list can enter the ring. The MicroMMAC-T retains this allowed list and automatically re-enables ring security whenever you power up or reset the unit.

You can select from two modes of ring security:

Alarm Only

Alarm/Remove.

Use the MicroMMAC-T in Alarm Only mode to add stations to the ring’s allowed list. In Alarm Only mode, new stations can enter the ring, but a “station added” trap notifies the Network Management Station (NMS) of the event. The trap includes the new station’s MAC address so that you can decide whether to retain the new station on the ring.

Each address you approve automatically becomes part of the ring’s allowed list. Later, you can add more stations to the allowed list by temporarily disabling ring security, then re-enabling it using the Alarm Only feature.

NOTE: Do not enable Ring Security on more than one management module per ring because one management module is sufficient.
