10.2.5.2
vap security cipher (access point)
Description
With this command, you configure the encryption method for the WPA authentication.
Note
This command is available only in access point mode.
Note
iPCF or iPCF-MC mode enabled
If you want encryption with AES in iPCF or iPCF-MC mode, only keys with a 128 bit key
length are supported.
Requirement
You are in the Interface Configuration mode of the VAP interface.
The command prompt is as follows:
cli (config-if-vapX-0-Y)#
Syntax
Call up the command with the following parameters:
vap security cipher { auto | aes | tkip }
The parameters have the following meaning:
Parameter
Description
auto
TKIP or AES is used depending on the capability of the other station.
aes
AES (Advanced Encryption Standard):
Strong symmetrical block encryption
method based on the Rijndael algorithm that further improves the functions of
TKIP.
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
derived from a main key.
Note
The encryption methods "WEP" and "TKIP" are 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 <vapX 0/Y>
command.
