Hi,
Currently, one of my customer is using the following configuration. It looks a little strange for me, 
can anyone help to introduce why they use the protocol ikev1 not ssl vpn cllient ? Any benifit compare with SSL VPN client?
************************************************************
group-policy GroupPolicy1 attributes
 wins-server none
 dns-server value 1.1.1.1 2.2.2.2
 vpn-tunnel-protocol ikev1        <------Here
 split-tunnel-policy tunnelall
 split-tunnel-network-list value AnyConnect
 default-domain value aaa.local
 webvpn
  anyconnect modules value dart,nam
************************************************************
Thanks a lot.
