Access Interface is going up and down within 3 seconds

I have 3 AP330, running latest firmware.

What could be the reason my Aerohives are going down and up within 3 seconds for quite some time?

First I thought it could be because of a bad ethernet cable, but I rechecked all cables and patch panels and everything seems ok. Could it because of interference? In our area channel 36 and 44 are quite crowded already!

The interfaces that are coming up and down are 2.4 GHz radio sub-interfaces rather than the Ethernet interface (Eth0 and/or MGT0) so the issue shouldn't be caused by a bad Ethernet cable.

How have you completed your 2.4 GHz channel configuration?

We are seeing the same issue. The interfaces are going up and down across multiple APs. We've completed our configurations and rolling out 8 additional units. We don't remember seeing this when we just had 4 units on one floor. We are running AP121 and HiveOS 6.1r2.1359 .

Try the following commands:


no int wifi0 ssid [SSID assigned to the wifi0 interface]
int wifi0 mode access
int wifi0 ssid [SSID assigned to the wifi1 interface]
no int wifi1 ssid [SSID assigned to the wifi1 interface]
int wifi1 mode access
int wifi1 ssid [SSID assigned to the wifi1 interface]


If you have more than one SSID assigned to a wifi interface you have to remove all the SSIDs from the interface before trying to change the interface mode to access. You will also need to add each of the SSIDs to the wifi interface after chaning the interface mode to access.

Sorry, noob here... I did a Show Interface on 2 of the access points and the wifix.x are all showing as Access. I don't believe we are trying to convert them to access.

We spoke with support and they had us turn off Track IP Groups for Backhaul under Additional Settings under 2 - Configure Interfaces & User Access. We also removed the Access Console. That seemed to resolve most of the problems. We also had a few issues with 2 adjacent APs on the same 2.4ghz network.

I ran into this problem as well yesterday with a client running HMOL 6.1r3 and HiveOS 6.1r2, and I thought there was a DoS attack or power issue to all the APs. In fact at two points in the day there were two mass de-authentication events. The event logs have very similar events to yours, Rob. Lots of SSID unbinding and access interfaces bouncing.

I made the changes to IP tracking and Access Console and that has resolved the issue so far.

hello,
I've got the same problem, and our customers are confused about many reconnections to wlan networks.
I set up a new AP121 in my office with the same Network Policy and get the same Problems.
Massive bouncing of the wifi interfaces and service disruptions (clients de- and reauthentication, Packetloss while Pinging).

Software version is newest 6.4r1.
There are no Track IP Groups selected for the network policy, which i could turn off.
Other accesspoints and network policies and ssid are affected to.
All customers and APs are in the same vHM and Hive.

Any idea to solve this problem?
Thanks a lot!
Robert





UPDATE: I've shutted wifi1 on one AP, and no more events. But this could not be the solution, because we need both wifi (na and ng).

Update 2: I've tried the workaround with the 16 customers AP121, but it doesen't it completely. The events counters are less now, but still exists. I guess before shutting down the na wifi, na and ng interference each other inside the AP. Now the ng wifi interference with other AP ng wifi interface.

It looks like this happens only to the AP121. But we only have two AP230, so this not so sure.

Hi Robert, did you figure it out with 230' ?

I am experiencing this behavior on both 2.4 and 5 GHZ radios with IP tracking off on all APs,  We are running 6.6r1.  Has anyone resolved this issue by doing something other than turning IP tracking off?
