SNMP Adapter

The SNMP (Trap) Adapter consists of a UDP SNMP server listening for SNMP traps. It includes the SNMP Adapter Configuration Manager to convert information from Management Information Base (MIB) files into cell classes, and map and enumeration configuration files used to format traps into cell events.

The SNMP Configuration Manager has a web-based interface that enables you to perform the following tasks:

• Publish MIB files
  This process converts information from MIB files into cell classes. The SNMP Configuration Manager uses the mib2map.pl utility to automate this process.
• View and edit the MAP file
  The MAP file manages the translation between SNMP traps coming from an external source and a cell event. Each instance of an adapter is related to a MAP file. To get the name of the MAP file that has to be configured, the SNMP Configuration Manager refers to the MapFile parameter in the first enabled instance of the SNMP Adapter in the mcxa.conf file. The mcxa.conf file is located in the installationDirectory\pw\server\etc directory. installationDirectory\pw\server is the path to the cell and the BMC Event Adapters configuration and executable files.
  
  If you have not specified a file name for the MapFile parameter, the SNMP Configuration Manager uses the mcsnmptrapd.map file name by default. This book uses mcsnmptrapd.map to refer to the file that is configured for the MapFile parameter.
• Unpublish MIB files
  The process of unpublishing MIB files removes information about the selected MIB files from the mcsnmptrapd.map file.
• The SNMP adapter receives SNMP traps and populates them to the event cell for visualization as raw event data out-of-the-box. Administrators and users can view SNMP traps in the GUI without any configuration, other than enabling the out-of-the-box SNMP adapters. Administrators can review raw SNMP trap data prior to configuration and importing of MIBs.

Before you install the SNMP Configuration Manager, you must install the BMC Event Adapters and enable the SNMP Adapter.
