Before starting the adapter, check each adapter file to determine if it defines the
behavior you want from the adapter.
Configuration File
The configuration file defines the behavior of the adapter, which runs as a server
daemon. The configuration file can have the common keywords described in
“Configuration File” on page 9, as well as the following adapter-specific keywords:
AdapterSpecificFile=path
Specifies the full path name of the object identifier file. This
keyword is required if the object identifier file is not in the same
directory as the configuration file.
SNMP_PORT Specifies the port where the adapter listens for SNMP requests.
SNMP_TRAP Specifies the port where the adapter listens for SNMP traps. Only
change this value if the producers of events are configured to send
to the alternate port.
Class Definition Statement File
The CDS file defines how events are constructed from information sent by SNMP.
It is described in detail in “Class Definition Statement File” on page 18 and in
Appendix C, “Class Definition Statement File Reference” on page 155.

4:ATTR(=,"portIndex") ;
FETCH
1:IPNAME($SOURCE_ADDR) ;
MAP
hostname=$F1 ;
boardIndex=$V3 ;
portIndex=$V4 ;
sub_origin=PRINTF("board %s, port %s", $V3, $V4) ;
status=CLOSED ;
