I have come across a strange issue with NV2 security.
If I have an AP and clients that are running NV2 without security enabled and I go into any of the clients from the AP side of the network to enable security, when I enable the security checkbox in the clients NV2 tab the client will disconnect as normal but after that I lose TCP connectivity with the AP and everything that is plugged into the same switch as the AP. Almost like when the NV2 security is enabled and the client drops from the AP it is creating some sort of broadcast storm or Bridge loop. The only way to regain connectivity with anything on that part of the network/switch is to power cycle the switch.
Once I reboot the switch I have connectivity back again and if I go back into the AP and enable NV2 security that same client will connect with no issues. I can then disable security on the AP to go back and swap the rest of the clients to NV2 security and the same thing will happen every time I enable NV2 security on another client. It has been 100% repeatable on the AP and clients I have been working on tonight.
This only happens with NV2 enabled with no security and then enabling security on a client. If I switch the AP to Nstreme or 802.11 and then enable the NV2 security on the client the client will drop as normal and reassociate with the AP. I then go in and swap the AP back to NV2 with security enabled and everything works fine.
