Configuring Wireless LANs to Capture
a Specify the length of the key by selecting the appropriate option.
Keys can be either None, 40-bit, or 128-bit. Use the None option
if no encryption is used on the network.
Depending on the length of the key specified, some or all of the
adjacent fields become active, enabling you to specify the keys in
use.
b Specify the exact, case-sensitive value for each key in the
adjoining spaces provided.
NOTE: The four encryption keys in use on a WEP-encrypted network
are all typically the same length — either 40-bit or 128-bit.
NOTE: Key entries appear as asterisks to preserve their security.
