Configuring WPA2-CCMP (802.11i)
WPA2 is a newer 802.11i standard that provides even stronger wireless security than Wi-Fi
Protected Access (WPA). CCMP is the security standard used by the Advanced Encryption Standard
(AES). CCMP computes a Message Integrity Check (MIC) using the proven Cipher Block Chaining
(CBC) technique. Changing just one bit in a message produces a totally different result.
WPA2/CCMP is based on the concept of a Robust Security Network (RSN), which defines a
hierarchy of keys with a limited lifetime. The keys the administrator provides are used to derive
other keys. Messages are encrypted using a 256-bit secret key and a 256-bit block of data. The
end result is an encryption scheme as secure as any the Brocade Mobility 7131N-FGR Access
Point provides.
To configure WPA2-CCMP on the Brocade Mobility 7131N-FGR Access Point:
1. Select Network Configuration -> Wireless -> Security from the Brocade Mobility 7131N-FGR
Access Point menu tree.
If security policies supporting WPA2-CCMP exist, they appear within the Security Configuration
screen. These existing policies can be used as is, or their properties edited by clicking the Edit
button. To configure a new security policy supporting WPA2-CCMP, continue to step 2.
2. Click the Create button to configure a new policy supporting WPA2-CCMP.
The New Security Policy screen displays with no authentication or encryption options selected.
3. Select the WPA2/CCMP (802.11i) checkbox.
The WPA2/CCMP Settings field displays within the New Security Policy screen.
4. Ensure the Name of the security policy entered suits the intended configuration or function of
the policy.
