SNMP-Based Management

The device provides an embedded SNMP agent that lets you manage it using AudioCodes
One Voice Operations Center (OVOC) or a third-party SNMP manager. The SNMP agent
supports standard and proprietary Management Information Base (MIBs). All supported
MIB files are supplied to customers as part of the release. The SNMP agent can send
unsolicited SNMP trap events to the SNMP manager.
Note:
•
By default, SNMP-based management is enabled.
•
For more information on the device's SNMP support such as SNMP trap alarms
and events, refer to the SNMP Reference Guide.
•
For more information on AudioCodes OVOC, refer to the OVOC User's Manual.
8.1

Disabling SNMP

By default, SNMP is enabled. You can disable SNMP as described in the following
procedure.

To disable SNMP:
1. Open the SNMP Community Settings page (Setup menu > Administration tab >
SNMP folder > SNMP Community Settings).
2. From the 'Disable SNMP' drop-down list (DisableSNMP parameter), select Yes:
3. Click Apply.
8.2

Configuring SNMP Community Strings

SNMP community strings determine the access privileges (read-only and read-write) of
SNMP clients with the device's SNMP agent. You can configure up to five read-only SNMP
community strings and up to five read-write SNMP community strings. The device's SNMP
agent accepts SNMP Get (read-only) and Set (read-write) requests only if the correct
community string is used in the request.
You can also configure a unique password-like community string used for sending SNMP
traps. The device sends the traps with the community string.
Note:
•
SNMP community strings are applicable only to SNMPv1 and SNMPv2c; SNMPv3
uses username-password authentication along with an encryption key (see
''Configuring SNMP V3 Users'' on page 92).
•
You can enhance security by configuring Trusted Managers (see ''Configuring
SNMP Trusted Managers'' on page 91). A Trusted Manager is an IP address from
which the SNMP agent accepts Get and Set requests.
