[SNMP4J] Different results for -Ow and -Ot

[Fabian Nart]

Hi

I encounter a strange behaviour when I read from a certain snmp-table 
using the snmpj4 command line interface. When I walk through the whole 
table, i get all values (see below: First attempt). When i use the 
table-option (-Ot instead of -Ow), I receive some NULL-values (see 
below: Second attempt). I only copied a few lines to keep things clear, 
but there are many more NULL-values in the complete response.

Frank answered me to a similar question that it might have to do with 
the lexicographical ordering but I don't understand how this could help 
me out.

Thanks for comments, Fabian
