WEP keys can be stored locally on the A032 or fetched from a RADIUS server. Local keys are entered by the administrator and stored on the device. They are configured by setting the wep_key parameter to set. Unlike many other parameters, wep_key takes two values: the key number and its value. To erase a key, the value n can be used. As mandated by the specification, four keys can be entered; one must be set active by using the wepkeyactive parameter:
CMD:set wep_key 1 BF8D2E9D0D6F669F4A36DA254FA651AC
Configuration will be set at next restart CMD:set wep_key 2 n
Configuration will be set at next restart CMD:set wep_key_active 1
The A032 provides two WEP-related settings to help control associations. One is the WEP mode. Normally, the WEP mode is set to wep, which means that stations can use either a shared WEP key or a key from RADIUS to authenticate the station to the access point. The mode can also be set to open, for no authentication, personal, to require a key from RADIUS, or wifi, for compatibility with equipment that attempts open authentication but transmits using a shared key for encryption.
CMD:set wep_mode wep
Additionally, the administrator can specify a required key length so only longer keys are permitted. The wepkeyrange parameter takes two arguments, the minimum and maximum key lengths, specified in secret key bits. To allow all users to connect, allow anything from a 40-bit key up to a 128-bit secret key:
CMD:set wep_key_range 40 128
Configuration will be set at next restart
Alternatively, the key range can be set to normal to allow only 40-secret-bit keys or high to allow only 128-secret-bit keys:
CMD:set wep key range high
Configuration will be set at next restartAs noted in Chapter 5 , Nokia quotes all WEP
key lengths as the length of the secret key. Nokia's 128-bit keys have 128 secret bits and are not compatible with most other vendors' implementations.
