    Hello HP-UX folks,

            I have two machines here running HP-UX 11.00. They are connected
    to a Cisco 5500 series switch and on the switch we are seeing high
    numbers of FCS & Alignment errors on the ports that they are connected
    to. On the servers themselves, (via lanadmin) I am seeing very low
    numbers for these types of errors (completely different story on the
    servers)

    I have verified that the servers are both forced to 100FullDuplex in the
    lan device configurations and they are also forced to 100FD on the
    switch. The cables for both of these servers have been tested and no
    errors were detected. When I attempt an FTP transfer between the two
    servers I am only receiving 2MB/sec rather than the expected 10+MB/sec
    on a 100full-duplex network with very little load.

    Has anyone ever seen this before? Does anybody have any suggestions for
    things to look for to help track this down? Where can I get more
    information? Any next steps appreciated.

    Thanks
