Warning given by LibSMI is valid ???

Hi, Iam having an Index element of a row as "InetAddress" Type, which is in turn an OCTET STRING (SIZE (0..255)). So automatically the total OID Size of the element will be greater than 255. But LibSMI tool (In Severity Level-5) gives the following warning.... "index of row ` ' can exceed OID size limit by 144 subidentifier(s)" Whether the warning given by LibSMI is valid???? Regards, Vivekanandan.V

The warning is valid since the current SMI/SNMP framework limits OIDs to 128 subidentifiers. Libsmi computes how many subidentifier are needed to encode the worst case length index components and generates a warning if that does not fit into the 128 subidentifier limit.
You can of course ignore the warning. But you want be able to use the full 255 octets with conforming SNMP implementations.
