I like to display the OID as string. So instead of integer I have chosen some
char* as the key
initialize_table_messageTable(void) {
netsnmp_table_helper_add_indexes(table_info, ASN_INTEGER,
ASN_OCTET_STR,
ASN_INTEGER,
ASN_INTEGER,
ASN_INTEGER, 0);
}
but while doing snmpwalk I am not getting them as String
snmpwalk -v2c -c public -Oa localhost:11161 1.3.6.1.4.1.11456
ABC-MIB::messageType.0.3.65.70.77.98374.98374.4 = STRING: AFM
--OID has been displayed as 65.70.77 which is basically AFM
Where I expect to display as ABC-MIB::messageType.0.3.AFM.98374.98374.4 =
STRING: AFM
how can I achive this ?
