Hi All,
Thanks for your replies. Different ideas coming in. Let me check it out
in my lab and get back.
This query came in from a study partner who is focusing on L2 switching.
We were looking at options to block all dynamic negotiation features
like VTP, DTP, etc.
The solution to block DTP is straight forward (switchport nonegotiate)
but we couldn't figure out a way to stop VTP traffic. Thanks to you all
we are looking at several options to work on.
Since the MAC addresses used for the various protocols (VTP, UDLD, CDP,
STP, etc) doesn't figure on UNIVERCD, I think it would be unreasonable
for it to be questioned in the lab. But I doubt if there is a simpler
alternative.
Regards,
Pankaj K

Hi Pankaj
Would you be able to let us know where you came across this question?
Was
it from a particular vendor's workbook?
It's a good question, one that I haven't seen posted before. I'd be
interested in knowing what else this vendor has to present as a
head-scratcher.
Thanks, Sean
