This question was asked severel times but in my opinion never answered correctly.
Windows Server 2003 DHCP with IP 10.10.10.32 / 25
Relay Agent: Cisco Wireless Controller 5508 with IP 10.20.20.186 / 27
The 5508 unicasts the DHCP request from a wireless client to the DHCP server an adds option 82 to the DHCP packet. The value of option 82 is the MAC address of the access point and the SSID.
I snifferd the request and can see the option 82 in the request and the IP of the 5508 as relay agent.
I configured two scopes: 10.100.0.0/24 for VoIP-Cilents and 10.200.0.0/24 for Notbook-Clients
I configured two WLAN-SSIDs: "VoIP" and "Notebook" (both reachable via the same Access-Point)
Clients locked into "VoIP"-WLAN should get an IP 10.100.0.xxx
Clients locked into "Notebook"-WLAN should get an IP 10.200.0.xxx
Can Windows 2003 Server read the option 82 field to allocate an address from the right scope to the client based on the value (SSID) of the option 82 field?
