Map number simply tells you where you're at on the list of the local SNMP Agent's OID maps. Click "next" and "prev" to scroll through the list. To advance directly to a specific map, enter the desired number in the "Showing" box, then click Update.

This page enables SNMP Get/Set to objects indicated on the above map list. The available local OID's are assigned automatically. You may select which local objects are mapped to these OID's.

Internal data is multiplied by the scale factor when read by your remote SNMP manager (client). Data written by your SNMP client is divided by the scale factor before being stored internally. If the object referenced is an integer value, then scale factor will most often be x1 (no scaling). However, if the object is a floating point value, then the scale factor becomes more important. This is significant because INTEGER is the one universally recognized data type in SNMP. While floating point representations do exist, they are not universally accepted. Therefore, the oldest and best known recommendation for sending real numbers via SNMP is to scale them and send them as integer.

For each local objet to be accessed by the remote SNMP Client, enter the local object number and scale factor. The local data and object name will be shown for reference. The data returned to the remote SNMP client will be the indicated local value multiplied by the scale factor, then truncated to integer. Enter an object number, then click Update to add the mapping to the list.

Objects are not immediately available when entered in the list above. When you have finished making changes, click the Reload SNMP button to clear and reload the MIB. The MIB is also automatically reloaded every time you restart this device.

You can auto-fill the MIB by providing a count, starting index, and starting object, and then click Auto-Fill. This is a shortcut for assigning many MIB variables at once.

Check Confirm and click Clear to clear the content of this entire MIB branch.

To remove a variable from the MIB, enter the map number at the bottom of the screen and click Remove. The remaining variables will be moved up the list. To insert a new variable into the MIB, enter the position at which you wish to insert, and click Insert Before. To simply add a variable at the end of the list, click Next and enter the new variable.
