Hi,
i already deleted from vc but then i get second thought and i want them back. Yesterday i realized where problem is. I changed the switch vlan 1 to tagged and vlan20 to untagged. Before that i change iap vc uplink vlan to 20 and vc vlan to 20. after that iap's stopped working. Now returned switch vlan setting and now it's working. but now i cant see them because my management network is vlan20. i'm not understood why is not work on vlan20?
