CHAPTER 8 SNMP-Based Management
Mediant 4000 SBC | User's Manual
8 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.
● 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 OVOC, refer to the OVOC User's Manual .
Disabling SNMP
By default, SNMP is enabled. However, you can disable it 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 , and then reset the device with a save-to-flash for your settings to take effect.
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.
● 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 ).
● You can enhance security by configuring Trusted Managers (see Configuring
SNMP Trusted Managers ). A Trusted Manager is an IP address from which the
SNMP agent accepts Get and Set requests.
For detailed descriptions of the SNMP parameters, see SNMP Parameters .

To configure SNMP community strings:
1. Open the SNMP Community Settings page ( Setup menu > Administration tab > SNMP
folder > SNMP Community Settings ).
