Cipher Suites and WEP
Configuring Cipher Suites

Cisco 3200 Series Wireless MIC Software Configuration Guide
Because the root device’s WEP key 1 is selected as the transmit key, WEP key 1 on the non-root bridge
must have the same contents. WEP key 4 on the non-root bridge is set, but because it is not selected as
the transmit key, WEP key 4 on the root device 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 root device and any non-root bridges with which it communicates must use the same
WEP key for transmitting data. For example, if the MIC-enabled root device uses the key in slot
1 as the transmit key, a non-root bridge associated to the root device must use the same key in
its slot 1, and the key in the non-root bridge’s slot 1 must be selected as the transmit key.
Enabling Cipher Suite
Enabling Cipher Suite with 12.4(3)JK or Later Releases
Cisco 3201WMIC with 12.4(3)JK or later releases moves cipher settings from dot11 interface to each
SSID configuration. Cisco 3202 WMIC and 3205 WMIC supports this feature change starting 12.4(3)JL
release.
To configure cipher suite encryption, follow these steps,
beginning in privileged EXEC mode:
