Configuring Encryption Modes
Because the access point’s WEP key 1 is selected as the transmit key, WEP key 1 on the other device
must have the same contents. WEP key 4 on the other device is set, but because it is not selected as the
transmit key, WEP key 4 on the access point does not need to be set at all.
Note If you enable MIC but you use static WEP (you do not enable any type of EAP authentication),
both the access point and any devices with which it communicates must use the same WEP key
for transmitting data. For example, if the MIC-enabled access point uses the key in slot 1 as the
transmit key, a client device associated to the access point must use the same key in its slot 1,
and the key in the client’s slot 1 must be selected as the transmit key.
Enabling Cipher Suites
Beginning in privileged EXEC mode, follow these steps to enable a cipher suite:
