When I run my code below, this is what I get in the response.getResponse()
string:
<snip>
REPORT[reqestID=1745013846, errorStatus=0, errorIndex=0,
VBS[1.3.6.1.6.3.15.1.1.3.0 = 23]]
</snip>
Note that the number 23 is incremented and requested changes with each
subsequent execution of the code
So my problem is this: I don't get an error back in the response, yet I don't
see anything happening on my switch either (it should be turning off port
Gi0/8))
I would be most grateful to whomever can take a look at my code and tell me
what I'm doing wrong! :)
Regards,
James
