If you temporarily disable ring security to allow new users to enter the ring, you can use the Alarm Only
mode to re-enable ring security. When you select the Alarm Only mode, the TRXI stores the MAC address
of each station on the ring in the allowed list. This saves you from entering MAC addresses one at time
using the Stn Edit command.
•
Alarm/Remove
- This is the highest level of ring security. The Alarm/Remove mode sends a “Remove MAC
Frame Command” to new stations 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, a trap/alarm is
sent to the NMS informing it that “the station could not be removed.”
SAVE/EXECUTE
This command saves all security mode changes to the TRXI’s NVRAM. You must use the SAVE/EXECUTE
command for your changes to take effect.
NEXT_SCREEN
Use this command to scroll to the next screen of the allowed database list.
PREVIOUS_SCREEN
Use this command to scroll back to the previous screen of the allowed database list.
RETURN
Use this command to exit the Ring Security screen and return to the Device Setup screen.
RING SECURITY SCREEN FEATURES
The following sections explain how to use the TRXI’s Ring Security screen features. Ensure that your network
meets the requirements and conditions specified in the TRXI User’s Guide before you initiate ring security. You
must also set up the TRXI’s SNMP Traps screen to designate which Network Management Stations receive
trap/alarms (refer to the TRXI User’s Guide). This ensures that trap/alarms generated by ring security arrive at
the appropriate destination.
To access the Ring Security screen from the Device Setup screen, use the arrow keys to highlight the Ring
Security option, then press

. The Ring Security Screen shown in Figure 1 appears. To exit the Ring
Security screen, use the arrow keys to highlight the RETURN menu command, then press
