Configuring
Community Strings
A community string is an octet string, included in each SNMP message,
that controls access to system information. The SNMP software for the
module internally maintains two community strings that you can
configure:
■ Read-only community strings with the default “public”
■ Read-write community strings with the default “private”
When the SNMP software receives an SNMP request, the module
compares the community string in the request with the community
strings that are configured for the module.
■ SNMP get, get-next, and set requests are valid if the community string
in the request matches the module’s read-write community.
■ Only the SNMP get and get-next requests are valid if the community
string in the request matches the module’s read-only community
string.
When you set a community string, you can specify any value up to
48 characters long.
To configure the community strings:
1 Enter the following at the top-level menu:
snmp community
The system prompts you for the new community strings.
Enter new read-only community {?} [public]:
2 At the read-only prompt, enter the new community string.
Enter new read-write community {?} [private]:
3 At the read-write prompt, enter the new community string.
The following example retains the read-only community string as public
and sets a secret read-write community string:
