LOCAL MANAGEMENT

The Community Name Table option lets you set community names. Community names are passwords to Local Management and they are agents of security control to your SEHI. You control SEHI access by establishing up to four different levels of security authorization: Basic-Read, Read-Only, Read-Write, and Super-User.

If you have Super-User access, you can change 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 instructions on how to change them.

Community Name

Displays the user-defined name through which a user can access Local Management for the SEHI. Any community name assigned here acts as a password to Local Management.

Access

Indicates the access status accorded each community name. Possible conditions are:

Basic-Read

This allows read only access to Local

 

Management, but excludes read privileges

 

to the Component Trap screen.

Read-Only

This allows read only access to Local

 

Management, but excludes access to

 

security protected fields of the upper levels

 

of authorization (Read-Write or Super-

 

User).

Read-Write

This allows you to read and write to Local

 

Management fields, Excluding IP Address,

 

Subnet Mask, and Community Names.

Super-User

This access privilege gives the user read

 

and write access to Local Management.

 

Super-User allows read and write access to

 

all modifiable parameters including:

 

Community Names, IP Addresses, Traps,

 

and SNMP Objects.
