Rule 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 registers indicated on the above map list. The available local OID's are assigned automatically. You may select which local registers are mapped to these OID's. The only data type supported via the internal SNMP Agent is signed integer, therefore you must use scaling to provide real data as integers. This is an inherent limitation of SNMP which does not have any universally accepted method of transmitting floating point data.

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. Unsigned integers may be used to represent scaled floating point data provided no negative numbers are anticipated. The actual encoding of unsigned 64-bit integer in this implementation of SNMP is COUNTER64.

For each local register to be accessed by the remote SNMP Client, enter the local register number and scale factor. The local data and register 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 a register number, then click Update to add the mapping to the list.

Registers 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 local register, 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.
