The normal way of traversing a table (as used by "snmpwalk")
is to send a series of GETNEXT requests.

snmptable will attempt to use the GETBULK request instead,
to cut down on the number of queries that need to be sent.

But if you've got a broken agent (or broken MIB implementation),
that doesn't understand the GETBULK request, then this will fail.

So the -CB flag turns off this optimisation, and sends a series of
GETNEXT requests instead - just as "snmpwalk" does.

See any book on SNMP for more information about the basic
protocol operations.
