Hi All,
I am new to net-snmp.
I generated code using mib2c.iterate.conf for adslMIB. In create entry I am hardcoding the node value(for testing purpose only.) The problem is that
1. It is retriving first row only. and i am facing problem in the table switch over.
2. What should I need to do to stop it when the retrival of first row is over.
I am sending generated code
Thanks in advance
Regards
Shree Kant
