encryption
This command defines whether WEP or AES encryption is used to provide privacy
for wireless communications. Use the
no form to disable encryption.
Syntax
encryption { wep < key-length > | wdsaes < alphanumeric | hex >}
no encryption
• wep - The keyword that enables WEP encryption.
- key-length - Size of encryption key. (Options: 64, 128, or 152 bits)
• wdsaes - The keyword that enables 128-bit AES encryption.
- alphanumeric - Specifies an encryption key entered as an alphanumeric
string.
- hex - Specifies an encryption key entered as hexadecimal digits.
Default Setting
disabled

Command Usage
• Wired Equivalent Privacy (WEP) and Advanced Encryption Standard (AES)
are implemented in this device to prevent unauthorized access to your
network. For more secure data transmissions, enable WEP or AES
encryption with this command, and set at least one key with the
key
command.
• AES has been designated by the National Institute of Standards and
Technology as the successor to the Data Encryption Standard (DES)
encryption algorithm, and will be used by the U.S. government for
encrypting all sensitive, nonclassified information. Because of its strength,
and resistance to attack, AES is also being incorporated as part of the
802.11 standard.
• The WEP settings must be the same on all bridges in your wireless network.
• The WEP encryption length specified in the
encryption command and the
key command must match.
• The AES keys must match for each wireless bridge link pair.
• The AES key type value entered using the
key command must be the same
as the type specified in the encryption command.
• Note that encryption protects data transmitted between wireless nodes, but
does not protect any transmissions over your wired network or over the
Internet.
