sapwalk2 performs mibwalks from a specified starting oid and produces output in the format 
that can be directly utilized by our Simulator SimpleAgentPro.  It can capture in SNMP v1, 
v2c and v3.  

With the "-xv vlanstartoid" argument it will use community string indexing (csi) to capture 
vlan specific objects for all configured vlans on the device, starting from the oid specified
with this argument.  Here you should specify the dot1dBridge branch: 1.3.6.1.2.1.17

SimpleAgentPro "plays back" simulations with changing values for counter, gauge, and timetick 
objects.  You can specify a rate computation argument that will instruct sapwalk2 to capture 
multiple samples from objects of type counter with a specified interval and calculate an 
appropriate rate of change.  Applying this argument for an entire mibwalk will usually result 
in an unacceptably long time to complete a capture.  Instead, if you want to use this feature 
then break the walk up into sections, apply the rate computation argument only where desired, 
and concatenate the resulting walk files into a single file for upload.  

The usage for the command is as follows:
