7.8.4Viewing Multiple OIDs

Viewing several object identifiers at one time allows the user to quickly scan a MIB for the specific information that is needed. The WALK command scrolls through OIDs numerically sequential to the initial OID request. The STEP command scrolls the MIB Walk, one OID at a time. Cycling allows you to specify how many GETNEXT commands to cycle through for one OID.

7.8.5Walking Through OIDs

Use the following steps to WALK through an OID:

1.Highlight WALK, using the arrow keys, then press ENTER. “<INITIAL> OID (=F9)” appears.

2.Enter the OID (minus the prepend) and press ENTER. The screen will begin walking through the sublayers of the MIB available from the specified OID. Each OID listed displays the specified OID, its size, its type, and the data it contains.

3.Press the SPACE bar to stop the walk, or wait for “***MIB WALK COMPLETED***” to appear on the screen.
