5.3.4The Ring Security Screen

The Ring Security screen lets you control access to your token ring network. Figure 5-8 shows the Ring Security screen. When you enable ring security, the TRXI stores the MAC address of each station on the token ring network in a secure database or “allowed list.” Only stations on the allowed list can enter the ring. The TRXI can store up to 250 station MAC addresses on the allowed list. The TRXI retains the allowed list in its battery-backed Non-Volatile Random Access Memory (NVRAM). If you power up or reset the TRXI, NVRAM retains the allowed list and automatically re-enables ring security.

You can append the allowed list by temporarily disabling ring security, then re-enabling it using the Alarms Only feature. The TRXI acts as the Ring Security Monitor for the ring and provides security for the entire ring.

Note: You should enable the Ring Security feature on only one TRXI per token ring.

You can select two modes of ring security; Alarm Only and Alarm/Remove. In the Alarm Only mode, new stations can enter the ring, but a “station added” trap/alarm notifies the Network Management Station (NMS) of the event.
