If the read-write Community string is unknown, an alternative Community
key can be used. The alternative Community key is unique per ODU and can
be used only to change the Community strings. The alternative Community
key is supplied with the product, and should be kept in a safe place.
If both the read-write Community and the alternative Community key are
unavailable, then an alternative Community key can be obtained from Cer-

When you have the alternative Community key, click the Forgot Commu-
nity button and enter the Alternative Community key (

change the read-write Community string.
