Tutorial Part 4

In this fourth part, we will discover how to modify the default sysObjectID Database.

1. Start NetworkView
2. Select the menu File, Database
3. Be sure that the Active Database is SNMP OID (radio button on top)
4. The buttons <<, <, >, >> let you move to the first, previous, next or last record in the database. It contains more than 5000 Enterprises and sysObjectIDs.
   The first OID number is the number that was assigned to thecompany. For example 311 is the number assigned to Microsoft, 43 to 3Com, 9 to Cisco. As you can see, it is just one number that the company received from the authority in charge.
   The device number is assigned by the company itself, starting of course with its enterprise number: it has more than one number separated with dots. Example: Cisco Catalyst 1900 is 9.5.28.
   But this is just the ending part of the sysObjectID, the full sysObjectID being: 1.3.6.1.4.1.9.5.28.
   You will find many sites dedicated to SNMP on the Internet if you need more info.
5. The buttons New and Del do what they are supposed to do. Most of the time, you will not use them: no reasons to delete, and adding is done from the Properties, SNMP Tab, Add To OID Database button of one of the nodes.
6. The Find button lets you access a record by either the OID or the Name (radio button).
7. The Type list box lets choose a type for the record: if it is only an enterprise number, choose the most frequent device type that the company produces. For example, for Hewlett-Packard, the enterprise number 10, you can select Printer. When discovering a new HP Unix system, it will be wrongly classified as a printer. Use then the Add To OID Database button to add this new device.
