In order to configure multiple SSIDs in a Cisco Aironet 1250 Series Access Point, we will follow the following scenario,
The Scenario is based on following hardware and software versions.
Cisco Aironet 1250 Series Access Point runs with an IOS Version 12.4(10b) JDA3.
Cisco Catalyst 3560 Switch runs with an IOS version 12.2(44) SE1.
Cisco Catalyst 6500 Series Switch runs with an IOS version 12.2(18) SXF14.
The Cisco Aironet 1250 Series Access Point has three VLANs, – VLAN 100, VLAN 101 and VLAN 102. VLAN 100 will be the native VLAN, VLAN 101 for the ITKE admin department and VLAN 102 for the guest users. The Wireless users who belong to ITKE admin department must connect to the Cisco Aironet 1250 Series Access Point and should be able to connect the ITKE admin department users on the wired network which is VLAN 101.
The wireless guest users should be able to connect to the Internet Gateway or web server which is on the wired segment of VLAN 102.
A Cisco Catalyst 3560 Switch is connected to the Cisco Aironet 1250 Series Access Point at the access layer and the Cisco Catalyst 3560 Switch is also connected to the Cisco Catalyst 6500 Switch at the Core/Distribution layer). All VLANs are created in the Cisco Catalyst 6500 Switch which is beyond the scope of this document. (If any one feels he or she needs the sample configuration for the VLANs in the Cisco Catalyst 6500 switch it can be provided in the comments section of this blog entry).
A windows 2003 Server is used as a DHCP server which provides the IP address for both the VLANs VLAN 101 and VLAN 102. A DHCP scope has to be configured for both VLANS in the windows 2003 Server which is also beyond the scope of this document. But I am just adding the snap shot from the DHCP Server.
The following IP Address Scheme is applied for the VLANs
VLAN 100– 10.0.0.0 /23 (NATIVE VLAN)
VLAN 101 – 10.2.0.0/23
VLAN 102– 10.4.0.0/23
Following are the IP address used for the devices in this document.
· The Cisco Aironet 1250 Series Access Point Bridge-Group Virtual Interface (BVI) IP Address (VLAN 100) 10.0.0.99.
· Windows 2003 DHCP Server with an IP address 10.0.1.100 with VLAN scopes configured
· Web Server with an IP Address 10.4.0.100.
· Wireless Clients (SSID ITKE) gets connected to VLAN 101 gets an IP address from the Windows 2003 DHCP Server from the subnet 10.2.0.0.
· Wireless Clients (SSID Guest) gets connected to VLAN 102 gets an IP Address from the Windows 2003 DHCP Server from the subnet 10.4.0.0.
In my next post I will post the configuration steps required to carry out the above motioned task. Until then do leave your comments for any future improvements or suggestions.
