TKIP Relay log message

[r-reed]

I'm getting a lot of these messages in my logs on an 1121G AP. We are doing 802.1x with WPA. Can someone tell me what this means?

Nov 17 18:52:47.967: *** TKIP Replay[ucast q 4]: TA=000c.f14c.9a6f, RSC=0x4A113,

TSC=0x4A112

TSC=0x634BA

Thanks

The message points to a device that is attempting to use an older WEP key in the rotation. When the AP detects this it notifies that the client is not up to speed in the key rotation.

Usually this is due to client issues, bug in AP code or potentially a hacker trying to gain access to the network.
