System information

210 The Tools Menu
• The “Choose existing SNMP devices...” button allows you to pick an SNMP device
to create a MIB profile from a list of SNMP devices that have already been defined in
or discovered by Observer.
After you have a profile (or a number of profiles) defined, the SNMP MIB walker looks
like this:.
1. Select a MIB Walker profile.
2. By default, the initial OID for the walk will be 1.3.6.1.4.1. If you prefer to have your
MIB walk begin from another OID, enter it in the “Initial OID” textbox or use the
dropdown arrow if you've recently used another starting point.
1.3.6.1.4.1 is the “root” of the proprietary part of the MIB tree. A walk from
1.3.6.1.4.1 will give you information on the proprietary OIDs. To get information
from the standard OIDs, start the walk at 1.3.6.1.2.1.
3. Click the Start button to start.
4. SNMP Extension’s MIB Walker will step through all higher branches of the MIB tree
(starting at the initial OID) and display the results in the Walk Network Device MIB
Table Viewer.
The following buttons are active from the Walk Agent MIB Table Viewer after the walk
has been completed:
• Print button -allows you to send the table to a user-chosen printer.
• Save List button -allows you to save the table to a user-chosen text file.
• View Tree or View List button-allows you to switch between Tree View and List
View.
• Identify Nodes button-allows you to identify the walked nodes using a user-chosen
MIB file.
