Hi Everybody,
We haved changed of Service Provider in a branch. This little branch has a Cisco AP 2800 in Flexconnect mode, after migration, the AP doesn't connect anymore. The AP is reacheble from ping, trace, SSH, however, DTLS tunnel go to TEARDOWN. As I said, the device is reacheble and it can join to controller for a couple minutes. The flow connection is following:
Cisco AP<->SWITCH L2<->ROUTER(L3 & CPE)<->*MPLS Service Provider*<->FIREWALL PALO ALTO<-> SDWAN DC CENTER<->SDWAN ANOTHER BRANCH<->SWITCH CORE<->WLC
the same behavior occur last week in another branch, after rollback, the Cisco APs could connect inmediately. At this moment there are 40 access point joined successfully int he WLC
We had replaced the AP, opened a Cisco SR, run a lot of debugs, the result is the same. Service Provider just ran a couple of pings on different packeck size to test MTU, they argue that the issue isn´t their responsability.
I am going to attach some debugs and images. I hope someone has a better idea.
the mac of AP at debug moment was dc:8c:37:8b:be:c0
Awaiting your kind support.
