Hi!
I have a problem getting 2 1832is to talk to each other... They are both K9C controller capable mobility express App with the same software version 8.3.x. One is set up as a controller and has a fixed IP for the controller part and DHCP for the AP part. second one is joined to the same network and subnet. DNS CAPWAP discovery is used with a DNS record pointing to the controller fixed IP. I can see in the console of the connecting AP that it sends out a CAPWAP request and get an answer from the controller IP. it then starts DTLS setup. this is most of the times followed by a DTLS Teardown and a new discovery is initiated. But occasionally the process continues and I get CAPWAP Status: Join. I can see that it connects to the controller but before the process is done and root should occur I get BAD TLV Received followed by a packet was received that caused the connection to close and everything starts over again...
I have tried different cables and switch ports, no change... the only thing I can think of is that the switches are L2 but not L3 capable and also non managed. I told the customer that they need to get a managed L3 switch since they want to enable the guest network, but I didn't have one to test with.
Does anyone have an idea or have seen this before?
