Cisco 9120AXI-EWC-E deployment not working

as00001111 — Mon, 05 Jul 2021 19:14:17 GMT

Hi all!

I bought a C9210AXI-EWC for a small location.

I configured an ip address on Gigabit Ethernet 0.

My switchport is configured as a trunk and native vlan.

I'm not able to ping the EWC.

cdp neighbor detail on the switch is showing the ap, but no management ip address.

AP is flashing green and red in turn.

Can you tell me what's happening?

Thank you!

Make sure that the EWC gig0 is defined with vlan 0 and the you have switchport trunk native vlan AP management are un-tagged and that is how it has been for a very long time.

How can I define gig0 with vlan 0?

Just don't define an vlan setting on gig0. You will see under configuration > interface > wireless

Here are some links I used when testing and converting ap's to eWLC:

Hi,

problem is that I cannot ping the controller, that means I cannot access it via https.

I don't have any ip connectivity.

Yes that is why I mentioned to make sure you have the management vlan as untagged and that the switchport is also not tagging the vlan. If the port is trunked, make sure the native vlan is the network the ap will be in, or else you can use an access port, but don’t define a vlan for gig0. The links I posted helped me when I first tested out the 91x0 ewc’s because I too ran into that issue. I did everything from the cli because when I tried the UI to do the initial setup, it wasn’t working. If you have other 9120’s with ewc softwyout of the box, then try different AP’s. You only need one to be the controller and the others will join that one that you get working. Post your config that you have for your ap and the switchport.

Hi Scott,

as I mentioned in my first post, my switchport is configured with native vlan. For testing, I created an access port, but that didnÄt help either.

I talked to our cisco partner and they told me that the version on the AP (16.2.2) is not the correct version.

For ewc I need version 17.1.1

We tried everything and can't get it working.

Is it possible to do a software upgrade via usb port of the access point?

since I don't have any ip connectivity, I can't use tftp.

Re: Cisco 9120AXI-EWC-E deployment not working

as00001111 — Fri, 03 Jul 2020 14:15:50 GMT

When I plug in a USB stick in the USB port of the access point, the usb sticks LED doesn't run.

Do I need to activate the usb port?

Factory reset the ap and try to follow this guide to upload the image you want.

as00001111 — Fri, 03 Jul 2020 14:54:14 GMT

I did a full factory reset and did the basic configuration again.

Again, I don't have any ip connectivity.

Without ip connectivity, I cannot upgrade the software.

In my opinion, the ap is faulty.

The USB slot is not working either, only Cisco knows why insert a usb slot which isn't working.

Re: Cisco 9120AXI-EWC-E deployment not working

Scott Fella — Fri, 03 Jul 2020 15:56:01 GMT

The USB slot isn’t functional yet. Have you tried with other AP’s or is that the only ap you have? Open a TAC case and have them walk you through the setup or opens a Tac case and have them RMA the ap.

Do you by chance have another controller on same VLAN that management VLAN is on ? If so try changing you management VLAN to another VLAN and see it comes up. I had the same issue and after reading the install guide it states the EWC will not come up if another WLC is on the same VLAN . I had a 9800 WLC on the same VLAN I unplugged it and the EWC starting working after I did a reload.

I got three C9120AXI. One of them was ordered as ewc. that's the device I'm talking about.

The other two ap's got normal ap image and are configured with capwap ip.

I tried converting the ewc into capwap mode with

AP1#ap-type capwap

but that doesn't work either.

Hi,

I don't have any other wlc.

Convert one of your 9120 from capwap to ewc and test:

EWC to Capwap:

https://www.cisco.com/c/dam/en/us/products/collateral/wireless/catalyst-9800-series-wireless-controllers/presentation-c97-743422.pdf

I’m assuming that you configured the device since you have the controller prompt, why not share your config so we can review it?

Re: Cisco 9120AXI-EWC-E deployment not working

as00001111 — Sat, 04 Jul 2020 16:44:43 GMT

I configured the device via console.

I attached sh version and sh run.

When I try to convert the ewc to capwap:

EWC#wireless ewc-ap ap ap-type ap01 capwap
% Error: no ap_name exists

I will try to lab this up today or tomorrow… its a holiday here so we shall see if I get to it. One thing you need to know is that, the EWC controller will have an IP address for the ap itself and then an IP address for the controller. I use Mac address reservations for all my ap’s.
I added a screen shot of my EWC that I have running at home for an example.

Thank you for your efforts.

But in my opinion there is a hardware or software failure.

I should do a RMA.
