(You can change the IP address and/or port number for an existing trap destination. The
same effect can be achieved by removing a row and adding a new row).
Modify the IP address and/or port number for the appropriate row in the
snmpTargetAddrTable.
To disable a trap destination:
Change TagList on the appropriate row in the snmpTargetAddrTable to the empty string.
To enable a trap destination:
Change TagList on the appropriate row in the snmpTargetAddrTable to 'AC_TRAP'.

SNMP Manager Backward Compatibility

With support for the Multi Manager Trapping feature, the older acSNMPManagerIP MIB
object, synchronized with the first index in the snmpManagers MIB table, is also supported.
This is translated in two features:
SET/GET to either of the two MIB objects is identical.
i.e., as far as the SET/GET are concerned
OID 1.3.6.1.4.1.5003.9.10.1.1.2.7 is identical to
OID 1.3.6.1.4.1.5003.9.10.1.1.2.21.1.1.3.
When setting ANY IP to the acSNMPManagerIP (this is the older parameter, not the
table parameter), two more parameters are SET to ENABLE. snmpManagerIsUsed.0
and snmpManagerTrapSendingEnable.0 are both set to 1.

Element Management System

Using the Element Management System (EMS) is recommended to Customers requiring
large deployments (multiple media gateways in globally distributed enterprise offices, for
example), that need to be managed by central personnel.
The EMS is not included in the device's supplied package. Contact 3Com for detailed
information on the 3Com EMS and Enterprise VoIP Network solution for large VoIP
