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?
