Hi,

I have a problem how to implement SNMP protocol in EPICS.

I want to keep MIB file somewhere in the module, not in the /usr/share/snmp directory.

If I run snmpwalk I can:

snmpwalk -v2c -M +/vagrant/modules/e3-M300_GPS/M300_GPS/M300_GPSApp/MBG-SNMP-MIB -m All -c comm 192.168.XXX.XXX MBG-SNMP-LTNG-MIB::mbgLtNgRefclockState

and I get output:

MBG-SNMP-LTNG-MIB::mbgLtNgRefclockState.1 = INTEGER: synchronized(1)

 

How should I define my record in Db?

I did it like that:

record(longin, "$(P)$(R)RefclockState"){

  field(DESC, "Status of GPS refclock")

  field(DTYP, "Snmp")

  field(SCAN, "5 second")

  field(INP,  "@$(HOST) $(COMMUNITY) $(MIB)::mbgLtNgRefclockState Integer: 10")

}

Where:

$(HOST) = 192.168.XXX.XXX – this is of course fake address

$(COMMUNITY) = -c comm

$(MIB) = MBG-SNMP-LTNG-MIB

 

But I got error:

devSnmp: error parsing '192.168.XXX.XXX -c comm MBG-SNMP-LTNG-MIB::mbgLtNgRefclockState Integer: 10'

         format is 'host community oidname mask maxdatalength [set_format/special]'

Error (511,511) PV: P:R:RefclockState devSnmpLi (init_record) bad parameters

 

Any help how I can do this?

 

Best regards
