Then you need to check the length of the incoming value, to
see whether it will fit. Something like:
if (requests->requestvb->val_len >= 10 ) {
netsnmp_set_request_error(reqinfo, requests,
SNMP_ERR_WRONGVALUE);
return SNMP_ERR_NOERROR;
}

Checking your original code file, you actually registered the object
as RWRITE:
netsnmp_register_table_data_set(
netsnmp_create_handler_registration(
"pethPsePortTable", pethPsePortTable_handler,
pethPsePortTable_oid, DIM(pethPsePortTable_oid),
HANDLER_CAN_RWRITE),
^^^^^^^^^^^^^^^^^^ table_set, NULL);
That means that your handler is expected to cope with the various
SET modes.
Try changing this to 'HANDLER_CAN_RONLY'
