The SNMP Tools Screen

3.Press ENTER. If there is no instance of that OID, the return code will specify “MIB_NO_INSTANCE”, otherwise “DATA TYPE:” appears.

4.Enter the data type for that OID. Possible choices are integer, string, null, OID, IP address, counter, gauge, timeticks, and opaque.

5.Press ENTER. “DATA” appears.

6.Enter the value to correspond to the OID. If accepted, “<SET> OPERATION CODE: XXXX <OK>” appears, otherwise an error message appears.

Viewing Multiple OIDs

View several OIDs at one time to scan a MIB for specific information. “WALK” scrolls through OIDs numerically sequential to the initial OID request. “STEP” scrolls the MIB Walk, one OID at a time. Cycling allows the user to specify how many GETNEXT commands to cycle through.

Walking Through OIDs

Use the following steps to “Walk” through OIDs:

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 begins 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.

Stepping Through OIDs

Use the following steps to “Step” through OIDs (the user can step through only after a GETNEXT):

1.Highlight STEP, using the arrow keys, then press ENTER. “Specify OID” appears.

2.Enter the OID (only the suffix is necessary) and press ENTER. The Tools screen begins to scroll one OID at a time, through all of the sublayers of the MIB available for that OID.
