Multiple SSIDS on an Aironet 1130ag DHCP issue.

Last Modified: 2008-01-09
We have multiple Cisco Aironet 1130ag access point that we want to run without a controller.
We have two SSIDS that need to be broadcast via these APs.  The problem is that if a client connects to either SSID, they authenticate with our Radius server properly.  But do not recieve an IP address via DHCP.

The switch and ports the APs are connected to have VLAN access for both SSIDS. If I configure only one SSID, clients still do not receive an address via DHCP.  If i configure both SSIDS, and change the Native VLAN to either VLAN of the SSID, they will receive an address via DHCP.  Ive tried adding the appropriate IP Helper addresses to point to the DHCP server with no success.

Any thoughts or suggestions?
Watch Question

Question : where do you set the ip helpder address ? it should be at the Layer3 routing between the vlan point (switch or router).


I figure the issue out.  The devices the APs are connected to are nortel switches, in order to get the APs static address to register we had to set the port as untagged.  Once communication became established to the AP, we had to set the port back to tagged.  This allowed clients to properly aquire an IP Address via DHCP.

I'm not sure WHY the nortel switches had to be flipped for a split second to work.  But at least its resolved.
