I can't get ip from dhcp when I'm flexconnect

CCC3 — Fri, 21 Jun 2024 10:45:23 GMT

I tried to get dhcp using flexconnect but failed.

If you remove the ap and connect the pc directly to that port, the dhcp will be received well

However, if you connect the ap and the radiating ssid, you can't receive it.

Switch port is set to trunk and native vlan is also set.

Should I set up central dhcp in Flexconnect group?

And is the result different depending on what you put in the wlan interface and the svi you created to test separately from the management?
I don't know the difference between the two.

Please give me some advice

wlc is 5520.

- Have a checkup of the 5520 controller's configuration using : WirelessAnalyzer input (procedure) for AireOs controllers
and feed the output from that into : Wireless Config Analyzer

- Use latest software available for the 5520 : https://software.cisco.com/download/home/286284738/type/280926587/release/8.10.196.0

Did yo map vlan to WLAN on your FlexConnect group config (Assume AireOS WLC). Also your AP mode should be "FlexConnect" and "FlexConnect Local Switching" enabled on your WLAN.

Hi Friend
when you connect the PC directly to which VLAN the PC is connect ?
I think the PC is connect to native VLAN same VLAN of AP
the issue is in SW config mostly
do
show vlan brief
see if the VLAN used for SSID is add to SW VLAN db or not
