Cisco AP stby 9115

I would like to operate 2 products of cisco ap 9115.
You set the virtual controller IP for the two APs to XXX.XXX.XXX.232.
IP was set to 233 and 234 respectively as an Access Point.
If you boot after setting it up like this, one AP will boot to stand by mode. I checked that there are two access points in the WEBUI.
What settings do I need to run two APs simultaneously as a single virtual controller?

Both run as AP and one runs the EWC. If both APs are in the same subnet, they will pick up an IP by DHCP and register itself to the EWC. In the GUI you can set the IP statically under Configuration -> Wireless -> Access-Points.

This is exactly what is done by default. All additional APs run CAPWAP mode to connect to the EWC.

What settings do I need to run two APs simultaneously as a single virtual controller?

as i understand this scenario, One of the AP act as master and another one act as Slave to become active ?

check EWC high availability :

hello 

https://www.cisco.com/c/en/us/td/docs/wireless/controller/ewc/17-7/config-guide/ewc_cg_17_7/m_ewc_high_availability.html

I've read this document and there's something I don't understand very well.
This document describes priorities for active and standby APs.
My question is, can't there be two active APs? When one AP operates, does one AP have to be a standby AP?
I want to give 172.19.96.232 IP to a virtual controller and use it as Access Points IP 172.19.96.233, 234, but only 234 works.
I've read the docs but I haven't found a way to activate 2 APs.
Or should the mode of the AP be different to set up only one virtual controller and use two different IPs?
 
 

I think you get confused with APs and EWC.

You can have many APs; they serve the clients. All are controlled by one Embedded Wireless Controller (EWC). There is only one, and it runs on the designated AP that you defined. But if this AP fails, the role of EWC will move to the standby AP, which is also defined by your configuration. The IP of the EWC will move with the role. There is no standby IP.

If so, I understand that if you operate 2 ap, you should operate 1 as ewc and 1 as ap.
I set up the ewc, but how do I set up the ap?

I created an EWC and made the IP connecting to the WEBUI 172.19.96.232
Access Point IP gave 172.19.96.233.
Here I want to add 1 AP to give 172.19.96.234.
Can I know the Mode or how to set it up in 172.19.96.234?
Documents for reference are also good.

Both run as AP and one runs the EWC. If both APs are in the same subnet, they will pick up an IP by DHCP and register itself to the EWC. In the GUI you can set the IP statically under Configuration -> Wireless -> Access-Points.

I ran two at the same time.
IP is set to 172.19.96.232 and access point IP is statically given by me 233 and 234 respectively. 1 AP starts with stby -.
Is there any setting I need to do before running two APs?

I was looking for another document.
When operating two APs, can I operate one as EWC-Mode and the other as CAWAP?

This is exactly what is done by default. All additional APs run CAPWAP mode to connect to the EWC.
