Using CMU SNMP 3.4 with the PortMaster Obtain the file cmu-liv-mib.txt from ftp.livingston.com. It is located in the /pub/le/snmp directory. The file cmu-liv-mib.txt contains the original cmu-snmp mib.txt with the Livingston specific extensions appended to the file. If CMU SNMP is installed and working correctly, rename any existing /usr/local/lib/mib.txt to /usr/local/lib/mib.orig (The pre-compiled version for Linux may require the file to be placed in /usr/lib). copy cmu-liv-mib.txt into the /usr/lib directory and rename it mib.txt. To test that everything works, type: snmpwalk public ".1.3.6.1.4.1.307"
