Hi Dave I have read many RowStatus documentations and still not sure how to use it.
My tables are actually kept in kernel, and not in agent itself and I use "mib2c.raw-table.conf" to create their structure in mib2c. After adding RowStatus column, mib2c created a c file with variables with the names "xxxxxNotifyRowStatus" and "old_xxxxxNotifyRowStatus" but without any type. I tried to define it as long - but still had issues. The value of the status is all rows is "0", which is not defined if I am not mistaken. Setting it to other value cause TimeOut error. Is there an example C file for such case? Thank you.

That is the whole purpose of the RowStatus textual convention! Have you read the MIB definition of this type? There is a long, long description clause, that explains exactly how a user can use it to add/remove rows from the table. > And what do you mean by " depends on how the MIB table is defined"? You haven't said anything about what MIB table(s) you are implementing. Whether these are tables that you have defined yourself, or whether you are working with something that someone else has provided. If the table is defined to include a RowStatus column, then this can be used to add/delete rows. If it's defined without such a column, then the description of the table needs to state how (and whether!) rows can be added or removed. For example, the TCP-MIB::tcpConnectionTable does not have a RowStatus column, but the definition of the tcpConnectionState object describes how it can be used to terminate a connection (and hence remove a row from the table). You can't create a new row in this table via SNMP - since that would imply creating a new connection between two arbitrary network ports. That doesn't really make sense - so isn't supported in the table. Always remember - the SNMP information is designed to mimic the underlying state of the computer your are trying to manage. If one side of this changes, that needs to trigger an equivalent change in the other System->SNMP is no problem - just refresh the data being reported. But SNMP->System implies a lot more work, and is not always possible.
