144APPENDIX E: AUTOMATIC ATTRIBUTE ASSIGNMENT

Excel Worksheet The lookup-tables are stored in Excel named-ranges. Lookup named-ranges can be stored on separate worksheets or in the same worksheet. To create a named-range, simply select the cells containing your data, select Insert/Name/Define from the menu, supply a name for your range and click Add. The worksheet can contain any other information you want and this does not interfere with the lookup.

The range’s name must be the lookup-table name (IP_1 for example) and the first row consists of Traffix Manager attribute names. dblookup looks for named-ranges first, before looking for lookup worksheets.

Excel Workbook The lookup-tables are stored in Excel workbooks on a one-table-per-worksheet basis. In this case, the worksheet name must be the lookup-table name (IP_1 for example) and the first row consists of Traffix Manager attribute names. The worksheet may not contain any other information apart from your lookup-data.

Running dblookup The user can have many different lookup databases, each running with its own copy of dblookup and so with its own entry in the user-defined attribute configuration file. The database location should be passed to dblookup as its first parameter.

For example, if two lookup databases companies.mdb (Access database) and continents.xls (Excel workbook) were contained in c:\data, then you could add the following two lines to the user-defined attribute configuration file:

Companies dblookup.exe c:\data\companies.mdb	TRUE
Continents dblookup.exe c:\data\continents.xls	TRUE

Attributes would then be assigned to devices based on the contents of these two databases.

If you change the contents of the configuration file, then you must restart the Traffix Manager Server for your changes to take effect.

Lookup databases may be modified ’on the fly’: the dblookup program always uses the most recent data from the database, and does not need be restarted when the data was changed.

How dblookup Works dblookup tries to open the database provided on its command line, then looks for the lookup tables.
