ip dhcp pool test-pool
network 192.168.21.0 255.255.255.0
dns-server 8.8.8.8

For instance, if you had 2 controllers with 192.168.20.10 and 192.168.20.11:

string = F1 + (2*4) + C0A8140A + C0A8140B = F108C0A8140AC0A8140B

ip dhcp excluded-address 192.168.21.1 192.168.21.100

How to Configure TKIP on Cisco 5520 WLC

TKIP has been deprecated since the 2012 802.11 Standard and should no longer considered a secure encryption type. However, if you must use TKIP to support legacy devices in your environment, here is how to enable it on a Cisco 5520 WLC.

Cisco has disabled the ability to enable TKIP from the GUI.  It must now be done from the command line.
