[ENG] 15.4. [DKSF 54.3 IU] Support of SNMP Trap
A formal description of SNMP TRAP notifications can be found in a MIB file DKSF_54.3.x_MB.mib, attached to the firmware of a device NetPing 4/PWR-220 v4/SMS. It can be downloaded from the page with a description of a device, the section «Documentation and files». An SNMP TRAP notification is sent in the format SNMP v1, while a description in a MIB file has a format SNMP v2c.
Unambiguous mutual coexistence of the identification of SNMP TRAP notifications for v1 and v2c is described in RFC3584 «Coexistence between Version 1, Version 2, and Version 3 of the Internet-standard Network Management Framework».
As a rule, software for processing SNMP converts between two formats without any difficulties.
To send SNMP TRAP, there is a need to:
- specify IP address for sending SNMP TRAP on the page «SETUP» of a device web interface;
- allow sending SNMP TRAP notifications by switching corresponding checkboxes. More detailed information is given in the section «[ENG] [Draft]15.2. [DKSF 54.3 IU] Configuring Sending SNMP TRAP Notifications»
