5.3.4 The 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.
Figure 5-8. Ring Security Screen
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.
