Hi,

The following is my MIB.

Whenever I am calling=20

snmpset -c public 127.0.0.1 mVgSipDnsServerRowStatus.1.\"1.1.1.1\" i 4.
the row is getting created.

=20

But when I am trying to modify the column of the created row using the
following command

snmpset -c public 127.0.0.1 mVgSipDnsServerPriority.1.\"1.1.1.1\" i 2

=20

The function mVgSipDnsServerTable_get_next_data_point() returning
NULL,because of which the function=20

netsnmp_extract_iterator_context() is returning null and I am not able
to modify the contents of the created row.

Can any one please help me.
