Access Points Joining 3850 next generation switches

Rob Johnson — Sun, 04 Jul 2021 07:44:47 GMT

It's my understanding that APs can join 3850s if and only if the APs are directly connected to ports on the 3850 next generation device.

Can someone point me to where this is explained?

Well you need to make sure the 3850 is also a MC and has license.

Scott, Can you point me to where it's documented that the APs need to be connected directly to one of the ports off that switch?

Here is configuring mobility controller

Scott,

I'm not sure why you included the link (Mobility Configuration Guide, Cisco IOS XE Release 3SE (Catalyst 3850 Switches))

Is this perhaps a way for Access Points that are not directly connected to the 3850 to join the Wirless Lan Controller portion of the switch?

Re: Access Points Joining 3850 next generation switches

Scott Fella — Sun, 01 Sep 2013 19:04:54 GMT

No... If you are using the 3850 as the controller, it doesn't matter if the APs are connected to it or another 3850, you need ap license and you also have to define the 3850 as the MC.

If Switch 1 is setup as a MC and switch 2 is setup as MA, you're saying APs connected to Switch 2 can join the MC of Switch 1?

Re: Access Points Joining 3850 next generation switches

Scott Fella — Sun, 01 Sep 2013 20:14:00 GMT

You need on MC... After that, all APs that connect to a 3850, will terminate to that switch. The MC is like the WLC function, its the brains.

Rob Johnson — Sun, 01 Sep 2013 20:25:15 GMT

so if i have a 3850 mobility controller then access points connected to a 3850 mobility agent switch can in fact join that mc?

Thank you Scott for your responses above.

I now have a better understanding how this works.

No problem. Hope I was able to she'd some light.

Access Points Joining 3850 next generation switches

CB90021204 — Thu, 05 Sep 2013 04:52:39 GMT

Can you non-directly connect APs to a 3850. For example if you had a multiple offices within one branch site and your 3850 MC was in the server rack and had 2960s in the other offices. Could you connect your APs to the 2960 switch and have them joined to the 3850 MC?

I've read that APs need to be directly connected to the 3850 however it supports flexconnect?

Would appreciate if anyone could shed some light.

Thanks,

CB90021204 - APs indirectly connected to a 3850 (connected to a downstream switch) will not join the 3850

Q. Does the Cisco Catalyst 3850 support indirectly connected access points?

A. No. The Cisco Catalyst 3850 switch will always terminate the CAPWAP tunnel locally. Pass-through mode or indirectly connected access point is not supported at this time.

The 3850 and 5760 controllers do not support Flexconnect at this time. Only Airespace controllers support Flexconnect/HREAP today.

Just to add, FlexConnect isn't part of converged access as the AP's terminate directly to the 3850's so there is no need for FlexConnect.

If the backup switch is outside the mobility group to which the access point is connected (the primary switch), you must provide the IP address of the primary, secondary, or tertiary switch, respectively. In each command, the controller_name and controller_ip_address must belong to the same primary, secondary, or tertiary switch. Otherwise, the access point cannot join the backup switch.

is there any update now to this problem? I see that this post is 2 years old. is there any development after this? i have aironet 2600 CAPs scattered all over a building that am planning to connect to LAN BASE 3850 PoE switches and i have 3850 IP base as core switch to which the 3850 LAN base switches will be connected [back bone connection]. Will it b possible to make MC work in this scenario now? The AP licenses are installed on the core switch with the IP base feature.

In your case if all AP

Rasika Nayanajith — Sat, 09 May 2015 18:49:35 GMT

In your case if all AP connect to a 3850 (MA), then they can register to it using licence available on 3850 as MC.
