My 5508 WLC which runs version 126.96.36.199 is configured as a DHCP server for the AP management and here's my problem:
Client can not get the address,I am in location at 1F of AP, obtain an IP address and associated to this AP, but I got to address is the address section 2F instead of 1F address above. In this WLC the AP, power and channel have not been optimized, the adjacent channels are AP 1, the power display is 1.
Last night I test, disconnect reconnect several times, I was able to get to the same network to a different IP address.My AP is 1602I. LoaderVersion 15.2<2> JAX . This is why ?
Little confused about the actual problem..:-( Are you saying the none of the clients are not getting the ip address from WLC DHCP scope at all or are you saying clients are getting ip address from a difference scope (that is 2F clients getting ip from 1F DHCP scope?
Are the AP's also configured with pick up DHCP ip range?
Start getting not address, then get to the address, and in the WLC client properties I get to see the IP address, but display the associated interface is 2F, address segment is 2F, but the associated AP is on 1F. This is very strange.
I'm not sure if i understood your problem correctly :-(
With 1F and 2F are you referring to first and second floors? What modes are these AP's operating (local/flex-connect)
Also it is not necessary that wireless clients should get ip address from the same range on ip address which is configured with AP. Wireless clients ip address is defined by which interface your SSID is mapped to.
Not sure if my inputs will really help you as im still not able to figure out the problem which you are facing :-)
My AP's operating is local mode, 1F is the fist floor,2F is the second floor, I am trying to achieve is to connect to the 1F of the AP, acquired IP address is mapped to the corresponding 1F SSID and DHCP scope, but it is connected to the 1F of the AP, the assigned address is 2F, while the client properties to display is associated to the interface in 2F, AP is 1F of AP, so this is very strange.
Ok...Looks like i'm getting there in terms of understanding your problem now.
Which model of WLC are you using? Do you have Interface Grouping enabled on the WLC?Also the client connecting to same SSID on both floors?
I'm just wondering how you are able to get mapped to two different interfaces when connecting to same SSId :-)
My WLC model is AIR-CT5508-K9, I did not create the interface group, I have only AP-group, in the AP-group and the associated SSID interface, AP added to the AP-group.
The issue must be of mac-filtering and the mac-address of the clients may be filtered. If MAC filtering was in place, then inadvertent connections would not be able to obtain an IP address. In this case, I’m not using MAC filtering for security (unless you are counting DHCP scope depletion as a type of DoS attack). Rather, it is being used to ensure that legitimate users can get an IP address.
For more information please refer to the link-
Mac filtering doesn't make any sense as an issue.
Can you post the config of the AP group and a show interface summary?
