Is that happening with the latest code changes that I made ? For each of the variables from the SQL query, the construstor of the SnmpInterfaceUpgrade class is checking if they are null, empty or spaces only. If that the case, the code will consider the variable null (to simplify the rest of the code). Then, if the ifDescr and ifName are both null at the same time, I'm assigning the string "null" to ifName in order to avoid issues when building the directories. Alejandro.
