Ask HN: on iOS VPN – how to switch from Cisco AnyConnect to native iOS app?

I was using Cisco AnyConnect VPN on Android and now now I'm switching to iOS.

Cisco AnyConnect doesn't seem to work on iOS 9.0+. But there is a native iOS app in General Settings for that.

Thing is: Cisco AnyConnect required only URL, username and password. And I go these 3. Native iOS VPN app additionally requires type, description, server, remoteID, localID... Are these any standard settings, or do I need to go to VPN admin?
