SNMP Connection Handler
The SNMP Connection Handler can be used to process SNMP requests to retrieve monitoring information described by the MIB 2605. Supported protocol are SNMP V1, V2c and V3.
The SNMP connection handler will process SNMP requests sent by SNMP Managers to retrieve information described the MIB 2605. To enable the SNMP Connection Handler, the ds-cfg-opendmk-jarfile parameter has to be set to the OpenDMK jar files location.
Parent
The SNMP Connection Handler object inherits from Connection Handler.
