AIR-AP3802I-E-K9 Mobility Express Issues

Hello,

 

i bought 6 new "AIR-AP3802I-E-K9" APs and trying to setup a mobility express solution.

My first Access Point is already up and running as a primary controller.

Its not possible for me to join a second AP to this mobility express solution. All acess points are connected to the same switch, there is only one default VLAN 1. Switchports are configured as trunk ports. They all running the same software version : 8.8.120.0

All have: AP Image type : MOBILITY EXPRESS IMAGE
AP Configuration : MOBILITY EXPRESS CAPABLE

There is a DNS record which points to IP DNS query for CISCO-CAPWAP-CONTROLLER which is getting resolved by the secondary access point. Both Access Points can ping/reach each other.

 

Here is a log on a secondary access point:

Re: AIR-AP3802I-E-K9 Mobility Express Issues

Hi

 As per logs, the WLC does not responded to the client capwap request. Can you ping the Access Point from the WLC CLI?  This can be a connectivity problem. 

 

-If I helped you somehow, please, rate it as useful.-

Re: AIR-AP3802I-E-K9 Mobility Express Issues

yes,

 

 i can ping in both directions. from controller to ap and from ap to controller.

 

i downgraded both access points to 8.5.135.0 and removed the dns capwap record for autodiscovery.

i also tried to enter the controller with "capwap ap primary base"

 

here a log:

Use Access and not Trunk ports on the Switch, or configure a trunk native VLAN on all ports.
Also make sure that the Primary has correct NTP servers configured and that the time is synced correctly.

Re: AIR-AP3802I-E-K9 Mobility Express Issues

Hello guys,

 

finally solved this problem.

I looked into my switch running config and saw "wireless management interface vlan1" entry. Set this to "no wireless management interface vlan1" and all my APs could immediately join mobility express.
