UCD-SNMP Tutorial -- snmptable

Note: Much of this tutorial requires ucd-snmp-4.2.2!, so make sure you get it before running the commands found in this tutorial.

Note: A new tutorial for net-snmp 5.0 and above is available as well. The commands is the ucd-snmp specific tutorial will not work as expected if you are using net-snmp and not ucd-snmp.

The snmptable command nicely displays a SNMP table for you in an easy to read column based fashion. Consider the sysORTable, which you saw all the data from in the last section. It's hard to get a good feel about the correlation of data when its displayed in a long list, like the output of snmpwalk gives you. Instead, snmptable nicely formats it for you (though sometimes it can be a bit wide, like in this example):
