MVPHi ,
are you sure 161/UDP was detected on the IP address of a virtual server? The BIG-IP will not answer on port 161/UPD as long as there is not a listener defined.
What I think is more likely, is that it was detected on a self IP address. Take a look at K17333, this will explain why a self IP address might be listening on 161/UDP.
