Local VLAN ACL for connected 1242AG LAPs (LWAPP, DHCP Entries)

Unanswered Question
Nov 5th, 2008

Hello all,

I am having a slight problem when installing new APs onto my LAN infrastructure onto dedicated Wireless VLANs on my access/distribution switches.

I have the following for the newly install LAP to talk to DHCP and the WLCs:

AP --- local LAN ---- rest of network ----- dhcp servers and wlcs

Sometimes the APs do not register to the WLC (or it looks more like, to the DHCP servers) and when I take the ACL off, it all works.

Can anyone help me with this please? Does anyone have an example ACL?

Kind regards,


I have this problem too.

When the destination of a packet is a wireless client, it goes to the controller and then passes through the Lightweight Access Point Protocol (LWAPP) tunnel to the AP and off to the client. One thing that can be done to help mitigate this message is to only allow the VLANs that are used on the controller onto the trunk that goes to the controller with the switchport vlan allow command on the switch.
