Note When you configure TKIP-only cipher encryption (not TKIP + WEP 128 or TKIP + WEP 40) on any
radio interface or VLAN, every SSID on that radio or VLAN must be set to use WPA or CCKM key
management. If you configure TKIP on a radio or VLAN but you do not configure key management on
the SSIDs, client authentication fails on the SSIDs.
