I have a 5508 controller at our headquarters and am installing some 3502 AP's at a remote branch. Unfortunatly, the remote branch has a different Vlan setup for some reason and the vlan that is used for the WLC (90) is designated for telephony at this branch. Can I put the AP's on a different VLAN (10) without having any issues? I will still use DHCP option 43 to point them back to the controller. Below are the configs for the WLC interfaces and what I am proposing for the AP interfaces:
WLC Config
interface GigabitEthernet1/1/38
description WLC01
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 90
switchport trunk allowed vlan 1,10,50,90,91,390,410-413,610-613,800,810,811
switchport mode trunk
channel-group 5 mode on
!
interface GigabitEthernet1/1/39
description WLC01
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 90
switchport trunk allowed vlan 1,10,50,90,91,390,410-413,610-613,800,810,811
switchport mode trunk
channel-group 5 mode on
!
interface Port-channel5
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan 90
switchport trunk allowed vlan 1,10,50,90,91,390,410-413,610-613,800,810,811
switchport mode trunk
AP Interface Config
interface GigabitEthernet1/0/1
description *** Access Point AP001 ***
switchport access vlan 10
switchport mode access
spanning-tree portfast
Will this work?

Yes it will.. just make sure that is we are using any Firewall or something in the middle allow CAPWAP ports!!

Surendra,
I know with the HREAP, if the site goes down they can still operate, but is there any benefit to having the AP answer to the Main Controller in local mode? I thinking I could save some money by having the AP answer to the Main Campus controller as this new site will only need one or two APs.

Hi Pat,
When deciding to do LOCAL mode or CENTRAL SWITCH mode you need to consider a few items:
1) NAT -- If there is a NAT between both locations almost all customers would rather LOCAL mode. Reason being is the ability to access local resources without nat issues. Remember, central model has all traffic and IP addressing coming from the main office.
2) Internet / Main office connection - If the remote office is on a MPLS for exmaple. Using local switching is reartly used becuase if you lose the conenction with the main office you have bigger issues then having wireless access.
These are the 2 questions my customers always look at ...
I hope this helps...
