This view allows you to modify the security for the

Security Administration State
This section allows you to choose the level of
security for the ring. You may only select one
option at a time. Click on the desired option to
select it. The buttons indent to indicate the
selected option.
Disable
Disables the ring security. All stations are allowed
on the ring.
Enable with Alarm
Enables the ring security, and any station
entering the ring will generate an alarm unless it
is on the secure list. The device will place the
station address on the Allowed Stations list.
Enable with Remove and Alarm
Enables the ring security, and any station not on
the secure list that enters or currently resides on
the ring will generate an alarm and be removed
from the ring.
Allowed Stations
The list of stations currently allowed on the ring.
Double-clicking on an item in the list moves it to
the Disallowed Stations window. However, you
cannot move a station from the Allowed Stations
window if the security is set to Enable with
Alarm. A symbol (>) indicates that this station has
recently been moved to the Disallowed Stations
window from the Allowed Station window, and will
remain until the changes are applied.
Disallowed Stations
Acts as a scratch pad or buffer to store addresses
currently disallowed on the ring, but you may
want to move to the Allowed Stations window in
the future. The ring does not read this buffer to
deny ring access to certain stations, but rather
denies access to all stations not explicitly listed in
the Allowed Stations window. Double-clicking on
an item in the list will move it to the Allowed
Stations window. A symbol (<) indicates that this
station has recently been moved to the Allowed
Caution
Caution
Do not attempt to modify Ring Security
without a complete understanding of
Token Ring concepts. Removal of the
station acting as the connecting bridge
from the Ring Security Allowed Station
List can cause isolation from the ring.
