a. Cấu hình interface wlan-controller 1/0:
Đây cổng nối giữa bộ WLC controller và Router 2811. Đáng lẽ là tách rời thành riêng, tuy nhiên ở đây mình sử dụng module WLC.
c2811#configure terminal
Enter configuration commands, one per line. End with CNTL/Z. c2811(config)#
c2811(config)#interface wlan−controller 1/0 c2811(config−if)#ip address 192.168.99.254 255.255.255.0 c2811(config−if)#no shut
c2811(config−if)#end
c2811#
Để truy cập vào module WLC, sử dụng câu lệnh:
c2811#service−module wlan−controller 1/0 session
Trying 192.168.99.254, 2066 ... Open

1. Create two dynamic interfaces named vl15 in VLAN 15 and vl16 in VLAN 16.
(Cisco Controller) >config interface create vlan5 5
(Cisco Controller) >config interface create vlan6 6
2. Assign the IP address, netmask, and default gateway for these VLAN interfaces.
(Cisco Controller) >config interface address vl5
192.168.5.254 255.255.255.0 192.168.5.1
(Cisco Controller) >config interface address vl6
192.168.6.254 255.255.255.0 192.168.6.1
Note: The default gateway for the dynamic interfaces must be the sub−interface IP address on the router for the corresponding VLAN.
3. Create two WLANs 5 and 6 with corresponding SSIDs wlan5 and wlan6.
(Cisco Controller) >config wlan create 5 wlan5
(Cisco Controller) >config wlan create 6 wlan6
4. Bind these WLANs with the corresponding VLAN interfaces you created (on the wired side).
(Cisco Controller) >config wlan interface 5 vl5
(Cisco Controller) >config wlan interface 6 vl6
5. Configure the dynamic interfaces you created with a DHCP server IP address to forward the client DHCP requests to.
Since the DHCP server is configured on the router, it should point to the corresponding sub− interface IP addresses of the router. If you have an external DHCP server, then it should point to that IP address.
(Cisco Controller) >config interface dhcp vl5 192.168.5.1
(Cisco Controller) >config interface dhcp vl6 192.168.6.1
6. By default, the authentication method is dot1X and it is enabled. In order to work with open authentication, disable it with this command for both WLANs:
(Cisco Controller) >config wlan security 802.1X disable 5
(Cisco Controller) >config wlan security 802.1X disable 6
7. Default, 2 WLAN wlan5 and wlan 6 is disabl, not active. In order to work, eable it with this command for both WLANs
(Cisco Controller) >config wlan 5 enable
(Cisco Controller) >config wlan 6 enable
