The access point is configured with AES+TKIP WPA-PSK encryption. The universal client will display
the following system message when there is a mismatch in the encryption types during association
between the AP and the universal client:
%DOT11-4-CANT_ASSOC: Interface Dot11Radio0/1/0, cannot associate: WPAIE invalid multicast
suite exp=0x0050F204 act=0x0050F202
In this example, the universal client would have the multicast suite of 0x0050F204 (for TKIP) but instead
received the multicast suite of 0x0050F202 (for AES+ TKIP). Here are the different scenarios:
• If the universal client is configured for AES WPAv2 (encryption mode ciphers aes-ccm), the access
point must be configured for AES WPAv2. The universal client will associate with AES encryption.
• If the universal client is configured for TKIP (encryption mode ciphers tkip) The access point must
be configured for either 1. TKIP WPA or 2. TKIP+AES. The universal client will associate with
TKIP encryption.
• If the universal client is configured for AES+TKIP (encryption mode ciphers tkip aes) The access
point must be configured for TKIP+AES. The universal client will associate with AES encryption.
• If the access point is configured for AES WPAv2 WPAv2 (encryption mode ciphers aes-ccm), and
the universal client is configured with TKIP+AES (encryption mode ciphers aes-ccm tkip), you will
get a system message stating the multicast suite was not found.
