Is the Dynamic EAP Session Key 128 or 40 bits?

I know that the static Broadcast/Multicast keys can be setup to 128 bits. Anybody know about the Dynamic Session Key?

Thanks,

The Dynamic EAP Session Key can be 128 or 40 bits. The client and AP get configured for the key size.

Using the latest ACU, driver, and firmware, I DO NOT see place to configure 40-bit or 128-bit DYNAMIC SESSION KEY.

The ONLY configurable is the STATIC key for broadcast and multicast. This is configure in AP ONLY.

Thus I think the Dynamic Session Key is 128-bit. If it were configurable, it would be in the ACS RADIUS since it is the RADIUS that hand it out the Session Key.
