LOCAL MANAGEMENT
The trap/alarm includes the new station’s MAC address so that you can decide if the new station should be allowed to remain on the ring.
If you select the Alarm/Remove mode, ring security 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 the Remove MAC Frame Command fails to remove the new station after three attempts, ring security sends a trap/alarm to the NMS informing it that “the station could not be removed.”
The following section provides a brief explanation of each field and command on the Ring Security screen and instructions for using them.
Note: Before you begin, you must set up the TRXI’s SNMP Traps screen to designate which Network Management Stations receive trap/alarms (refer to the SNMP Traps screen section). This ensures that trap/alarms generated by ring security arrive at the appropriate destination.
Station Address
This field lists the MAC address of each station on the ring security allowed list. This field can lists up to 250 MAC addresses on 22 local management screens.
Stn Edit
The Station Edit command lets you add or delete stations from the allowed list. Use the Stn Edit command for single entry edits to the allowed list (refer to the Alarm Only security mode definition for information about adding multiple users).
Security Mode
This command lets you set the Security Mode for the ring. Security Modes determine the level of ring security. You can select the following Security Modes:
•Disabled - This is the factory default setting. Use this option to temporarily disable ring security so that new stations can enter the ring.
•Alarm Only - In this mode, ring security allows new stations to enter the ring. When a station enters the ring, ring security sends a “station added” trap/alarm to the Network Management Station.
