AP HREAP VS WLAN HREAP

I currently have a WLAN (lets call it WIFI1) that is configured for HREAP local switching. All of my APs are running in HREAP mode as well. Is there any way to run one of these access point in local mode that users can still connect to WIFI1? I tested this and it looks like you need both the WLAN and AP running in the same mode in order for clients to connect. Is this true?

AP HREAP VS WLAN HREAP

Hello Jason,

If I understand it correctly, you would like to have some of your APs in local mode so that the client traffic is tunneled back to the WLC. You can certainly accomplish this by using local AP mode.

The H-REAP local switching flag on the WLAN advanced configuration ONLY applies to APs in H-REAP mode. In other words, if you have APs in local mode, they will still service that WLAN, but traffic will be tunneled to the WLC and will use the defined controller interface that is bound to the WLAN.

Pat hit the nail on the head. I would just like to add..

Keep in mind when you tunnel the traffic back. If you have remote sites connected via VPNs your clients in local mode will get a "central" IP address. Which in some cases may break local printing etc ...

AP HREAP VS WLAN HREAP

Thanks for the quick updates. I was able to get this to work. I had the DHCP server misconfigured on the interface so that was causing some issues. One other question. I will be broadcasting multiple WLANs from these APs. One of the WLANs I would like to continue to keep in HREAP mode. But I have a guest WLAN that I want to switch to local mode so all traffic traverses back to the controller for the Guest WLAN. Can you have one WLAN in HREAP mode and another WLAN in local mode on the same AP? And if yes, do you change the mode within the WLAN settings?

AP HREAP VS WLAN HREAP

Yes, you can.

You don't need to change the mode, just don't tell the "Guest" that it is HREAP Local Switching.  By default the AP will backhaul this traffic to the WLC.

AP HREAP VS WLAN HREAP

Hello,

I just have a little question to be sure: if you set up the APs in Hreap mode, and not the Wlan, the trafic will be tunneled back to the WLC ?

Thanks to you,

Re: AP HREAP VS WLAN HREAP

No.. It will drop traffic off on the ap management vlan.

Thanks,

Re: AP HREAP VS WLAN HREAP

Scott I think you are mistaken there or misread the question.

If the AP is setup as an HREAP AP but no WLANs are set for HREAP support then all the traffic comes back to the WLC. Traffic is only left at the AP if you enabled HREAP support on the WLAN and specify a VLAN tag.

Re: AP HREAP VS WLAN HREAP

If the AP is in H-REAP and local switching is enabled on the WLAN, then the traffic is placed locally. If the AP is in H-REAP and local switching is disabled on the WLAN, then traffic is tunneled back. So when an AP is in H-REAP mode, you either specify the SSID to vlan mapping or else if not, traffic is placed on the AP management vlan. I guess I still might not get what was asked:)

Re: AP HREAP VS WLAN HREAP

I tought you need to enable local switching on the the Wlan to drop trafic at management port ?

In fact, I have two SSID, i would like one to be tunneled back to WLC and not the second one.

Thanks,


EDIT: our emails crossed each other

thanks to you

Re: AP HREAP VS WLAN HREAP

Well then make sure the WLAN you want tunnels back does not have local switching enabled.

Have you looked at this guide?

Re: AP HREAP VS WLAN HREAP

Ok thanks, just a little problem with a customer who claimed that a wlan with HREAP disabled didn't send back trafic to WLC...

He was so sure of himselft, i started to doubt

So we're agree.

Thanks a lots,

Re: AP HREAP VS WLAN HREAP

Just double check the config... Just in case they made any changes.

Thanks,
