- The MIB browser applet allows you to load and browse multiple MIB modules and view data
- on an SNMP agent. You can also view real-time graphs, and tables, of SNMP data.
-
- Version 1.1 includes a number of enhancements, including an SNMP walk capability,
- configurable options for the line graph, table display, etc. You can use HTML
- applet parameters, to determine which MIBs are loaded at startup. Applet parameters
- also support setting default host and community string parameters, as well as the
- SNMP port of the agent to be used. Please see the supplied HTML files for details.
-
- If you need to load additional MIBs, choose "Load MIB" and specify the MIB module file
- to load a MIB. Once a MIB is parsed, you will see the root node for the MIB tree in
- the SUB-NODES list box. Double click on a MIB node to move down the MIB tree.
-
- At any point in the MIB tree, you may select "Get" to get all the objects under that
- node. Of course, the hostname for the agent and a valid community string has to be
- entered as well. On some platforms, a patch is required to use IP addresses. Once
- you select a leaf node (the SUB-NODES list will be empty), you can select "Getnext" to
- get the first instance of that object from your SNMP agent. You can also specify the
- instance yourself, by adding it at the end of the Object ID, e.g. adding .0 for
- scalar variables.
-
- Once a variable has been selected, choose graph to view a real-time graph of the data.
- You can modify some of the graph parameters, e.g. the polling interval, on the graph.
- To change the polling interval, simply change the value and hit enter.
-
- You can choose "Get" at any point in a MIB module, and an SNMP walk will begin. Hit
- "Stop" when you want to stop the walk. If an SNMP table selected, a formatted table
- will be displayed based on data obtained from the SNMP agent. The "Clear" button
- clears the Results area, which is needed when it stops working after a lot of output
- data is written to it.
-
- If you are loading the MIB browser and SNMP classes from a web server it's likely that
- SNMP operations will not work and a java application program supplied with this
- Package needs to be run on your web server host. The demo from our server will not
- allow SNMP comunication, since we're not running this program on our host.
-
- Once the browser has been loaded from the network, MIB loading and browsing should
- work in any case with MIB modules in applet directory. rfc1213-MIB, rfc1271-RMON and
- rfc1155-SMI (an empty module) are available in the applet directory for loading and
- testing. Just specify the file name in the dialog. Some of these may also be needed
- when you have imports in your other MIB modules.
-
- If you've copied all files to your local file system, set your CLASSPATH as specified
- in the tutorial in a shell window (or DOS window), and start appletviewer or your
- browser from that same shell window.

- setting up your environment so you can get the complete functionality of this applet.
