Security and authentication
11.3 WLAN
Note
iPCF, iPCF-HT, iPCF-MC mode enabledt
If you want encryption with AES in iPCF, iPCF-HT or iPCF-MC mode, only keys with a 128 bit
key length are supported.
Requirement
You are in the Interface Configuration mode of the WLAN interface.
The command prompt is as follows:
cli (config-wlan-context-x)#
Syntax
Call up the command with the following parameters:
wlan security cipher { auto | wep | aes | tkip }
The parameters have the following meaning:
Parameter
auto
wep
aes
tkip
Note
The encryption method "TKIP" is not available with the transmission standards "802.11n" and
"802.11n only".
Result
The encryption method is configured.
Further notes
You display the settings with the show wlan security command.

Description
TKIP or AES is used depending on the capability of the other station.
WEP (Wired Equivalent Privacy)
A symmetrical stream encryption method with only 40- or 104-bit long keys based
on the RC4 algorithm (Ron's Code 4).
AES (Advanced Encryption Standard):
Strong symmetrical block encryption method based on the Rijndael algorithm that
further improves the functions of TKIP.
TKIP (Temporal Key Integrity Protocol): A symmetrical encryption method with the
RC4 algorithm (Ron's
Code 4). In contrast to the weak WEP encryption, TKIP uses changing keys de‐
rived from a main key.
