Management VLAN issue at Cisco AP

Yesterday, I met strange issue for configuring Cisco AP.

My client requested like this.



Untagged VLAN is 1

Two Tagged VLAN 100,200.

VLAN 100 be management and VLAN 200 be Service.



After configuration, I tried to connect Web management tool.

but anything response from AP. even ICMP dosen't works.



then, I found Cisco support community's related discussion.

about 2 years ago, same problem issued by one person.

At that time, he also tried to configure tagged VLAN as management VLAN.

but failed like me. no one could solve the problem. and still now.



Finally, I told this issue to my client. and setup VLAN 1 as management.



This problem gave little disappointing for me about Cisco AP.
