Cipher Suites and WEP
Configuring Cipher Suites
8
Cisco 3200 Series Wireless MIC Software Configuration Guide
bridge(config-if)# encryption vlan 1 mode ciphers ckip-cmic wep128
This example sets up a cipher suite for VLAN 1 that enables AES as the encryption mode:
bridge# configure terminal
bridge(config)# configure interface dot11radio 0
bridge(config-if)# encryption vlan 1 mode ciphers aes-ccm
bridge(config-if)# end
Matching Cipher Suites with WPA
If you configure your bridges to use WPA or CCKM authenticated key management, you must select a
cipher suite compatible with the authenticated key management type.
Table 3
lists the cipher suites
that are compatible with WPA and CCKM.
Note
When you configure TKIP-only cipher encryption (not TKIP + WEP128 or TKIP + WEP40) into SSID
configuration, the SSID must be set to use WPA or CCKM key management. If you configure TKIP but
you do not configure key management on the SSID, the authentication fails on this SSID.
For a complete description of WPA and CCKM and instructions for configuring authenticated key
management, see the
“Authentication Types”
document.
