Variables in MIB
This dialog box contains a list of SNMP variables known to Network Manager. The Variables in MIB list is a hierarchy, like the directory and file lists in any Open File dialog box. Double-click an entry surrounded by [brackets] to enter it. The first entry, [..], goes up one level of the tree. You can edit items with no brackets.

MIB Path
The full MIB variable name.

Variable Name
The name of the selected variable. If this is an end-node (not in brackets), you can perform Get, GetNext, and Set operations on it. You can also type the variable name directly into the Variable Name text box.

For the Get and Set operations, you must specify an instance number after the variable name. For example, if you select sysLocation, the Variable Name box contains "sysLocation". You must click Next or change this to "sysLocation.0" to perform a Get or Set operation.

Variable Value
Variable Value displays the results of a Get or GetNext operation. Edit the Variable Value to enter the value required for a Set operation. The format of Variable Value depends on the MIB variable type, as described below. You must enter the value in the proper format. The list below the Variable Value text box displays any aliases that are defined for an INTEGER type variable. You can move a new alias value to the Variable Value text box by pulling down the list and selecting an entry.

Variable Type
When you select a variable, and when a Get, GetNext or Set operation is performed, one of the Variable Type options is automatically selected.The variable type defines the data entry and display format for the value:

Number
INTEGER, COUNTER, or TimeTicks. Data is a number. However, if aliases are defined in the MIB, an ASCII word is displayed. For example, the value for ifOperStatus is displayed as "up" or "down".

String
OCTET PRIM TYPE with printable data (DisplayString). Data is formatted as text characters with no quote marks. Example: This is a printable string.

HexArr
OCTET PRIM TYPE. Data is formatted as a list of two digit hexadecimal numbers, representing one byte each, and separated by a single space(for example, 22 3E 44 A1 10).

IP Addr
IP ADDRESS PRIM TYPE. Internet dot notation (for example, 128.9.118.0).

ObjID
OBJECT IDENTIFIER. Data is formatted in MIB dot format, optionally with a leading text identifier (for example, sysObjectID.0 or 1.3.6.1.2.1.1.2.0).

Variable Description
A text box displays a description of the selected variable from the MIB source file.

Next button
After selecting an end-node variable name (one with no square brackets around it), use the Next button to perform an SNMP GetNext operation, which gets the value of the next variable in the MIB supported by the node.

The Get and GetNext operations use the Get Community name defined using the Edit Node command. The result of the Get and GetNext operations is a variable name and variable value. The name will be displayed in the Variable Name text box, and the value will be displayed in the Value text box. The Variables In MIB list will be updated so that it displays the tree level containing the returned variable name.

If the node rejects the request, a message will be displayed. If no response is received, Network Manager will retry the request the number of times specified by the Poll Retries command (Config menu). If no response is received a message will be displayed.

Get button
After selecting an end-node variable name (one with no square brackets around it), use the Get button to perform an SNMP Get operation, which gets the value of a specified variable.

You must specify a variable instance identifier to use the Get operation. This can be done in one of two ways. Use the Next command repeatedly until the appropriate variable and instance number is displayed in the Variable Name text box. You can also manually edit the variable name (for example, change ifInOctets to ifInOctets.0 to specify an instance).

The Get operation uses the Get Community name. The Variable Name, Value and Variables In MIB boxes are updated as with the GetNext operation.

Set button
After selecting an end-node variable name (one with no square brackets around it), use the Set button to perform an SNMP Set operation, which changes the value of a variable.

You must specify a variable instance identifier to use the Get operation. Use the Next command repeatedly until the appropriate variable and instance number is displayed in the Variable Name text box. You can also manually edit the Variable Name (for example, change sysLocation to sysLocation.0 to specify the instance). In either case, you should perform a Get operation to see the current value before changing it.

The Set operation uses the Set Community name. The Variable Name, Value and Variables In MIB boxes will be updated as with the Get operation.

Repeat button
Use the repeat button to display multiple table entries, starting at the currently selected entry. You can use this function in concert with the Export button (described below) to export multiple table entries to a file or printer. The Repeat Options dialog box prompts for repeat options.

Click Repeat to specify a repeat until the end of the MIB, or forever. If you repeat forever, the first MIB variable is retrieved after the last MIB variable.

Use the Operation list to specify the repeat operation. The Get operation will repeatedly retrieve the currently displayed entry. The Next operation will retrieve consecutive entries in the table. You can also select the Set operation, but be careful because failing set operations create a large number of log error messages.

Use the Delay list to select the number of seconds to wait before retrieving the next table entry. Set the Show Descriptions check box to update the variable description for each operation.

Use the Start button to start the repeat command. While the command is in progress, all buttons are disabled except for the Stop button.

Stop button
Use the Stop button to cancel the current SNMP operation. This button can be used to stop a command when a node is not responding, or to stop a repeat command.

Top button
Goes to the top of the MIB tree.

Up button
Goes up one level of the MIB tree. You can also double-click the [..] entry.

Export button

Use the Export button to export any retrieved variables to a file. A dialog box prompts for the export file name. The saved entries will be in the following format:
