Forgotten Community string
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 Com-
munity 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 Ceragon Customer Support using the

serial number and the MAC address are displayed in the Site Configuration inventory tab.
When you have the alternative Community key, click the Forgot Community button and
enter the Alternative Community key (Figure 8-10). Then change the read-write Community
string.
