encryption key
Use the encryption key configuration interface command to define a WEP key used for data encryption
on the wireless LAN or on a specific virtual LAN (VLAN). Use the no form of the command to remove
a specific encryption key.
Note You need to configure static WEP keys only if your access point supports client devices that use static
WEP. If all the client devices that associate to the access point use key management (WPA, CCKM, or
802.1x authentication) you do not need to configure static WEP keys.
Note Encryption VLAN is not supported on bridges.

Syntax Description
Defaults This command has no defaults.
Command Modes Configuration interface
vlan vlan-id Specifies the VLAN number (1 to 4095)
key 1-4 Specifies the number of the key (1 to 4) that is being configured. (A total of four
encryption keys can be configured for each VLAN.)
Note If you configure static WEP with MIC or CMIC, the access point and
associated client devices must use the same WEP key as the transmit key,
and the key must be in the same key slot on the access point and the
clients. See
Table 2-9 for a list of WEP key restrictions based on your
security configuration.
size 40bit Specifies a 40-bit encryption key
size 128bit Specifies a 128-bit encryption key
encryption-key Specifies the value of the encryption key:
• A 40-bit encryption key requires 10 (hexadecimal) digits.
• A 128-bit encryption key requires 26 (hexadecimal) digits.
transmit-key Specifies the key for encrypting transmit data from the access point. Key slot 1 is
the default key slot.
