Re: Internal DHCP error in EWC ISR 1131

Hi All,

I have a problem when implementing internal DHCP on EWC using the ISR 1131 sdwan router. I configured the internal DHCP correctly but DHCP is not running. When I debug and display errors like this

as additional info, the IP Management of the WLC and AP is different from the dhcp pool that I created, the WLC and AP use Vlan 100 while the dhcp pool uses vlan 103, both gateways are configured on the sdwan router.
Does the EWC version not support internal dhcp?

- At first glance it looks like the DHCP pool (or setup) is not correctly defined ; can you post related
statements from the running configuration ?

Internal DHCP server for EWC is not supported.

https://www.cisco.com/c/en/us/td/docs/wireless/controller/ewc/17-3/config-guide/ewc_cg_17_3/dhcp_for_wlans.html

But, I have the impression that you created the DHCP scope on the router 4331? Or did I understood incorrectly?

how 4431 come into play?
