5. Configure the Key Settings as needed to set a 256-bit key.
Default (hexadecimal) 256-bit keys for WP2A/CCMP include:
1011121314151617
18191A1B1C1D1E1F
2021222324252627
28292A2B2C2D2E2F
6. Configure the Fast Roaming (802.1x only) field as required to enable additional
roaming and key caching options. This feature is applicable only when using
802.1x EAP authentication with WPA2/CCMP.
NOTE
PMK key caching is enabled internally by default when 802.1x EAP
authentication is enabled.
7. Click the Apply button to save the security policy and return to the AP-71XX
Quick Setup screen.
At this point, you can either restrict specific client access to the access point
(using the ACL) or test the access point for client interoperability.
Defining an IPSec VPN tunnel
A secure IPSec VPN tunnel must be established between the Brocade Mobility
7131N-FGR Access Point and the external server providing the access point’s
external NTP, syslog or Radius resources. Ensure the IP address of the external
NTP, syslog or Raidus resource is known, as it must be supplied to the access point
for the access point to properly access and communicate with the external
resource.
256-bit Key Enter 16 hexadecimal characters into each of the four fields.
Pre-Authentication Selecting this option enables an associated client to carry out an
802.1x authentication with another access point before it roams
to it. The access point caches the keying information of the client
until it roams to the other access point. This enables the roaming
client to start sending and receiving data sooner by not having to
do 802.1x authentication after it roams. This feature is only
supported when 802.1x EAP authentication is enabled.
