Security Mode (Toggle)
Allows you to set one of three security modes for the moduleÕs token ring.
Each mode offers more security than the previous mode. Select from the
following modes:
¥ Disabled - This is the default setting. 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 ÒStation AddedÓ trap/alarm is sent to the Network
Management Station. This trap message is only sent once, and it includes the
new stationÕs 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 Þeld.
Make sure you understand the consequences of changing security modes.
