Listing all the column OIDs within a GETNEXT request
will return the full information for the next row.
One request - one row.
If there are twenty rows in the table, it will take 20
(actually 21) requests to retrieve the complete table.
Listing all the column OIDs within a GETBULK request
will return the full information for the next N rows
(where N is the value for max-repetitions)
One request - multiple rows.
The same table can probably be retrieved with just
one or two requests.
Try running 'snmptable -d ....' on a table and compare the traffic
patterns with the results of 'snmptable -d -CB'
