There are three methods for limiting SNMP access.
Disable the SNMP management option.
Assign SNMP community names and access levels. The DSU/CSU supports
SNMP Version 1, which provides limited security through the use of
community names.
Limit SNMP access through validation of the IP address of each allowed
SNMP manager.
The DSU/CSU can be managed by an SNMP manager supporting the SNMP
protocol. The community name must be supplied by an external SNMP manager
accessing an object in the MIB.
To define SNMP community names, follow this menu selection sequence:

Refer to Table A-8,
General SNMP Management
Enable SNMP Management.
Assign the SNMP community names of the SNMP Managers that are allowed
to access the DSU/CSU's Management Information Base (MIB).
Specify read or read-write access for each SNMP community name.
