[Mohamed Sayed]

Hi all,

I have cisco PI2.2 and discovered all the network and i notified that there are some clients' IPs (Servers or PCs or Laptops or ....) not detected.

please advice what may be the issue ?

If you go to Monitor;switches you can see the client count will be 0 after a successful sync, that don't seem right.
