Setting Static IP for EWC built in AP on catalyst 9120

Good day all,

I am having trouble setting a static IP for the on board access point with the EWC software using the web UI. The software version of ewc is 17.6.4.

Initially i set a dhcp pool in ewc and the access point picked up an address. I then set the web UI to expert/advance mode and tried to configure a static IP for the AP doing the following: AP > General > IP Config > Enabled Static IP Option. Then I entered the desired ip, netmask etc and clicked save. however when the ewc rediscovers the internal AP it is not using the ip i set but saying the static IP is one from the dhcp pool that I have created and is not using the static ip that i set.

Does anyone know how to resolve this. I configured the ewc using the day 0 method of connecting to the broadcasted ssid containing the last few digits of the mac address for the ap and then using a web browser to run through the initial configuration like ewc static ip, user and so forth. wondering if i did something incorrect during the initial setup but cannot find any other documentation to show otherwise.

Thank you

- Initially , I can only say that 17.6.x is rather old , can you use a more recent version ?

@connor-smith

you may use CLI for this.

ap name Cisco_AP static-ip ip-address static_ap_address netmask static_ip_netmask gateway static_ip_gateway

The issue you described my fall into this note

"If you configure an access point to use a static IP address that is not on the same subnet on which the access point’s previous DHCP address was, the access point falls back to a DHCP address after the access point reboots. If the access point falls back to a DHCP address, enter the show ap config general Cisco_AP CLI command to show that the access point is using a fallback IP address. However, the GUI shows both the static IP address and the DHCP address, but it does not identify the DHCP address as a fallback address."

In simple' try config other SW/R to be dhcp server of AP not EWC.

exclude some addresses from the DHCP scope and then assign an IP from the excluded range, or use the switch to do the DHCP.

Like @Haydn Andrews says you probably forgot to exclude the static IP from the DHCP pool?
