Wireless Security Commands

AES-CCMP (Advanced Encryption Standard Counter-Mode/CBCMAC
Protocol): WPA2 is backward compatible with WPA, including the same
802.1X and PSK modes of operation and support for TKIP encryption. The
main enhancement is its use of AES Counter-Mode encryption with Cipher
Block Chaining Message Authentication Code (CBC-MAC) for message
integrity. The AES Counter-Mode/CBCMAC Protocol (AES-CCMP)
provides extremely robust data confidentiality using a 128-bit key. The
AES-CCMP encryption cipher is specified as a standard requirement for
WPA2. However, the computational intensive operations of AES-CCMP
requires hardware support on client devices. Therefore to implement WPA2
in the network, wireless clients must be upgraded to WPA2-compliant
hardware.
Example
mic_mode
This command specifies how to calculate the Message Integrity Check (MIC).
Syntax
mic_mode <hardware | software>
hardware - Uses hardware to calculate the MIC.
software - Uses software to calculate the MIC.
Default Setting
software
Command Mode
Interface Configuration (Wireless)
Command Usage
The Michael Integrity Check (MIC) is part of the Temporal Key Integrity
Protocol (TKIP) encryption used in Wi-Fi Protected Access (WPA) security.
The MIC calculation is performed in the access point for each transmitted
packet and this can impact throughput and performance. The access point
supports a choice of hardware or software for MIC calculation. The
performance of the access point can be improved by selecting the best
method for the specific deployment.
Using the “hardware” option provides best performance when the number
of supported clients is less than 27.
Using the “software” option provides the best performance for a large
number of clients on one radio interface. Throughput may be reduced when
both 802.11a and 802.11g interfaces are supporting a high number of
clients simultaneously.
