Chapter 5 - Command Line Interface
- For 128-bit keys, use 13 alphanumeric characters or 26 hexadecimal digits.
- For 152-bit keys, use 16 alphanumeric characters or 32 hexadecimal digits.
Default Setting
None
Command Mode
Interface Configuration (Wireless)
Command Usage
• To enable Wired Equivalent Privacy (WEP), use the auth shared-key command to select the
“shared key” authentication type, use the key command to configure at least one key, and use
the transmit-key command to assign a key to one of the VAP interfaces.
• If WEP option is enabled, all wireless clients must be configured with the same shared keys to
communicate with the AP.
• The encryption index, length and type configured in the AP must match those configured in the
clients.

5.20.4 transmit-key
This command sets the index of the key to be used for encrypting data frames for
broadcast or multicast traffic transmitted from the VAP to wireless clients.
Syntax

index - Key index. (Range: 1-4)

Command Usage
• If you use WEP key encryption option, the AP uses the transmit key to encrypt multicast and
broadcast data signals that it sends to client devices. Other keys can be used for decryption of
data from clients.
• When using IEEE 802.1X, the AP uses a dynamic key to encrypt unicast and broadcast
messages to 802.1X-enabled clients. However, because the AP sends the keys during the
802.1X authentication process, these keys do not have to appear in the client’s key list.
• In a mixed-mode environment with clients using static and dynamic keys, select transmit key
index 2, 3, or 4. The AP uses transmit key index 1 for the generation of dynamic keys.
