Figure 7-4 Community Name Table Screen

Community names are set through the Community Name Table option. Community names are passwords to Local Management and are agents of security control to the SEHI. SEHI access is controlled by establishing up to four different levels of security authorization: Basic-Read, Read-Only, Read-Write, and Super-User.

With Super-User access, the user changes the existing passwords by changing the community names. Only the community name assigned Super-User access has full management privileges.

The following sections explain each field on the Community Name Table screen and provides instructions on how to change them.
