Adding a key
Select Add Key. The Add Key Screen appears. 
The key identifier Key ID can be any numeric value from 0 – 255, and must be unique per inter face. You 
can not have two keys with the same key ID on an inter face.
The Authentication Key may consist of from 1 – 16 ASCII characters. These appear as asterisks when 
typed.
The Start Date and End Date formats are determined by the System Date Format, set on the Set Date and 
Time menu under the System Configuration menus.
The Start Time and End Time formats are determined by the System Time Format. The AM or PM pull-down 
menus do not appear if the time format is 24 hour time.
The End Time Mode pull-down menu allows you to select either Date or Infinite. This determines whether or 
not the key will expire at a specified time and date, or remain effective indefinitely.
End Date, End Time, and AM or PM do not appear if the End Time Mode is set to “Infinite”. Infinite means 
that the key begins when it begins, but it never expires. The acceptable year range is from 1904 – 2039.
When you are satisfied with your entries, select COMMIT and press Return. 
This menu will not accept a non-unique Key ID on the same inter face; failure to enter an authentication 
key; or a negative star t date, end date, or star t time and end time range.
Changes to RIP Keys on all inter faces are immediately effective. This differs from the remainder of the RIP 
configuration on the Ethernet LAN, which requires a reboot. It is impor tant that the keys be able to change 
dynamically, however, because the purpose of entering more than one key on an inter face is to insure a smooth 
transition between keys with no network outages.
