ASA (v9.8) DHCP server not stable

Herman2018 — Fri, 28 Aug 2020 14:53:02 GMT

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.
