Controlling SNMP Access

The FrameSaver unit supports SNMP Version 1, which provides limited security through the use of community names. There are three methods for limiting SNMP access:

HDisabling SNMP access.

HAssigning SNMP community names and the access type.

HAssigning IP addresses of those NMSs that can access the unit.

Disabling SNMP Access

When the SNMP access is disabled, the FrameSaver unit will not respond to

SNMP messages.

"Procedure

To disable SNMP access:

1. Select the General SNMP Management options.

Main Menu → Configuration → Management and Communication →

General SNMP Management

2.Disable the SNMP Management option.

3.Save your change.

See Configuring General SNMP Management in Chapter 3, Configuration, for more information about General SNMP Management configuration options.
