I've just purchased this model including the security plus license. The running ASA version is 8.0(2). The ASDM correctly shows the Security Plus license, as well as the new 100 VLan Max.
I am unable to turn the ethernet0/0 or 0/1 ports to 1000. The option is not available within the ASDM and when I try to set the speed using the line interface, I get the error "Invalid Input Detected".
Thanks for any help!
