Michael,

Is the port the AP is plugged into an access port, and accessing the VLAN the management interface is in?

Hi Michael,


are the APs and the WLC in the same regularoty domains?

What kind of code does the AP provide?

If you have ordered an AIR-AP1020-R-K9 the R in the number shows up the country code.

If the country code of the WLC and the attached APs differ they will not be attached.


Best regards,


Frank

Hi Michael,


the management port is only reacheable for the APs with the LWAPP. ICMP is not allowed.

The Management interface and the APs are in the same LAN Segment (VLAN) and subnet?

Is between the APs and WLC any Firewall, ACL or proxy?


Can you provide us with some more information:

- The output from "Management -> Logs -> Message Log"

- And maybe some more information like the VLAN Assingment, why you have choosen the Layer 2 Option.


Have a look here for the Layer 2 deployment:

The management interface will respong to ICMP requests. It is also the only supported means for direct connection to the controller for administration, ie http/https, ssh/telnet and SNMP.


If you could post a text copy of the config, less all the AP information, this will help us to be able to figure out why you can't reach it.

Dear Frank,


the management port and the ap?s are in the same subnet, no firewall, now access controll list, no proxy.

Must i have a distribution port?

Does the controller only communicate with the ap over the distribution port?

Becaus i cann?t ping the management port, will that be the reaseon.


Kind regards


Michael
