Security Mode (Toggle)
Allows you to set one of three security modes for the module's token ring.
!
Make sure you understand the consequences of changing security modes.
CAUTION
Each mode offers more security than the previous mode. Select from the
following modes:
• Disabled (default) - Use this mode to temporarily disable ring security so that
new stations can enter the ring.
• Alarm Only - In this mode, new stations can enter the ring and are added to
the allowed list, but a "Station Added" trap/alarm is sent to the Network
Management Station. This trap message is only sent once, and it includes the
new station's MAC address so that the network manager can decide if the new
station should be allowed on the ring.
When temporarily disabling ring security to allow new users to enter the ring,
use the Alarm Only mode to reenable ring security. In Alarm Only mode, the
management module stores the MAC address of each station on the ring in
the allowed list. This eliminates entering MAC addresses one at a time using
the Stn Edit field.
• Remove/Alarm - This is the highest level of ring security. In this security mode,
the ring is locked to new stations. The Remove/Alarm mode sends a "Remove
MAC Frame" command to a new station 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, remove alarm sends a trap/alarm
"Remove Failure" to the NMS, informing it that the station could not be
removed.
If you change directly from Disabled mode to Remove/Alarm mode, all stations
NOTE that have not been added to the allowed list will be removed from the token ring.
