8510 WLC Flexconnect AP Association Issues

Seeing a host of issues on a large multi-site flexconnect network. It could be a number of things, such as the APs having issues with the L3 routing over WAN DSL, or WLC issues including bugs in the 7.5 code or potentially AP management issues (what is the per interface AP management limit on these new WLCs?)

There are a number of small remote sites that run 2602 APs in flexconnect mode back to the main DC with an 8510 controller (v7.5.102.0). DTLS is disabled.

Prime registers many alarms for AP association/deassociation, and when searching for a site of APs on the WLC and re-searching, I never get the same number with a few APs ghosting in and out due to this issue.

Investigation on the APs themselves shows random de-assoc and assoc events lasting 15secs to 5mins or many more minutes. No obvious pattern.

The problem it's causing is clients on the WiFi end are cut off and their authentication session is left open on the central server not allowing reconnection.

I'm still trying to figure out if this is a bug, WLC set up issue in regards to AP registration, L3 AP operation or asymmetrical routing issue, or a combination of all of the above --so I thought I'd post it on here to see if anyone had any ideas while I continue trawling through configuration and logs...

Example AP log output:

Re: 8510 WLC Flexconnect AP Association Issues

There are a few thing I always check:

? Are there any logs on the switch or errors on the port the FlexConnect AP's are connected to

? Is the WAN latency less than 150msec

? I take a look at the up times and the ap join time vary as this can tell you a lot.

? there is a WAN latency feature available on the AP in the advanced tab.

Re: 8510 WLC Flexconnect AP Association Issues

Thanks for the reply Scott.

I haven't checked the switches yet, but they aren't Cisco so the CLI feature set is somewhat restricted. I will do this though as I need to confirm PoE as well, although the majority of APs don't have an uptime issue, only join issue which for this bad site is as little as 16s sometimes, but often achieves 5mins and some over an hour.

The WAN latency is probably an issue. I haven't done mass assessments yet, but I ran some quick ping tests from the local authentication proxy and saw 28/50/412ms and 28/159/1296ms for 1000 ping response. I was aware of the link latency check and I will be enabling shortly on the WLCs to various APs to see how the CAPWAP is seeing things.

Will post more info soon.

Here is a snippet of a report I ran on Prime:

Re: 8510 WLC Flexconnect AP Association Issues

The latency is what's the issue. Have you tried to enable link latency on these AP's. If you click on the FlexConnect AP and in the advanced tab, enable link latency and see if that helps. Your RRT times are very high and I don't know if you will ever get it working. Your only other option is to put a WLC at each site that has high RRT times. The WLC 2504 is pretty cheap and supports up to 75 AP's.

Here are the WAN requirements for FlexConnect

Re: 8510 WLC Flexconnect AP Association Issues

Yes, I enabled link latency when I posted earlier. I'm not convinced it's running right though as while I did see 2 of the 21 APs at this site with realistic results (eg: 10/1/1200) it seems they are mostly <1ms now which I am not sure is possible. Does the counter reset when they re-associate?

So we discovered the client auth issue. There were some remote sites with the same client DHCP scope (they are local scopes NAT'd and not routed over the WAN). The WLC was seeing multiple client devices with the same IP and inducing client exclusion via IP Theft, which booted off random clients at different sites. I disabled that to ensure client authentication can continue in those instances.

So now I guess the question is, other than local gateway connectivity / DHCP loss, is there anything that would affect user traffic? ie: frequent Flex state changes? These APs are configured for local switching, and they flip to standalone mode and continue to serve clients OK because the authentication in this case is managed by a local proxy and its sends auth traffic over the Internet, rather than through the WLC, so even new clients can connect when the CAPWAP tunnel is down. Testing I've done in the lab doesn't appear to affect anything, cell phone continues to browse and download fine, so appears to be more of a management headache than service affecting?...

8510 WLC Flexconnect AP Association Issues

Frequent joins can cause issue as a typical failure wouldn't cause flapping as much as a slow WAN.  You would have to baseline this with sites that don't have such a high latency as these other sites you have.  Again, Cisco recommends something like less than 300ms, anything past that, they will not support and will tell that's the reason.

8510 WLC Flexconnect AP Association Issues

Clients should still work fine as long as nothing happens when the AP joins and disconnects.  I have seen AP's reboot when they have lost connectivity to the WLC and they were in FlexConnect.  So it can be a nightmare especially with low latency WAN.
