Hi, ASA 9.8 run dhcp server on the internal sub-interface, the client PC very difficult to get the IP address.
the configuration is like below:
interface G0/1.10 -- nameif Staff-wifi
interface G0/1.20 -- nameif guest-wifi
then the interface G0/1 ---->(trunk (vlan 10,20)) --> the core switch G1/0/1 (trunk (vlan 10.20)).
the core switch port G1/0/48 is connected to wireless controller and configured as trunk port (vlan 10,20,100) Vlan 100 is management vlan of wireless controller.
DHCP is set to (Global) on wireless controller WLAN interfaces (guest-wifi,staff-wifi), and DHCP server IP is ASA interface G0/1.10 G0/1.20 IP respectively.
Anyone pls advise why dhcp not stable. Thanks.
