snmpwalk Unknown Object Identifier
Solution 1:
cmot: Unknown Object Identifier shows you that cmot isn't found in known MIBs.
You need add device's MIBs to snmp client via cp MY-MIB.txt /usr/share/snmp/mibs or use snmp client without MIB.
By example to get system info:
snmpwalk -v2c -c public 1.1.1.1 1.3.6.1.2.1.1
Or you can tell the tools to load MY-MIB file for this command only:
snmpwalk -m +MY-MIB -v2c -c public 1.1.1.1 cmot
