Chapter 25 | Wireless Security Commands

◆ WPA2 defines a transitional mode of operation for networks moving from WPA
security to WPA2. WPA2 Mixed Mode allows both WPA and WPA2 clients to
associate to a common VAP interface. When the encryption cipher suite is set to
TKIP, the unicast encryption cipher (TKIP or AES-CCMP) is negotiated for each
client. The access point advertises it’s supported encryption ciphers in beacon
frames and probe responses. WPA and WPA2 clients select the cipher they
support and return the choice in the association request to the access point.
For mixed-mode operation, the cipher used for broadcast frames is always TKIP.
WEP encryption is not allowed.
Example
AP(if-wireless 0: VAP[0])# auth wpa-psk

Command Usage
◆ Selecting a security method using the auth command, automatically enables
data encryption (WEP, TKIP, or AES-CCMP) for the VAP. Only use this command
when using WEP encryption with an Open System.
◆ Encryption is implemented in this device to prevent unauthorized access to
your wireless network. For more secure data transmissions, enable encryption
by selecting a security method using the auth command, or by using the
encryption command when using WEP encryption only.
◆ The encryption settings must be the same on each client in your wireless
network.
◆ Note that encryption protects data transmitted between wireless nodes, but
does not protect any transmissions over your wired network or over the
Internet.
