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.
