I'm seeing a problem with random error disabled ports occurring during workstation start ups.
The problem is not confined to any one brand or model of NIC card, any one switch or switch port module, and the cabling system with patch cord attached has been tested and certified good.
The ports and workstations are all configured for autonegotiate and the problem never happens in the same place twice.
How can I troubleshoot this ?
Can the NICs be sending spurious electrical signals to the port when the workstation first powers on and that causes the disabled port condition ?
Any insights into this issue would be very greatly appreciated.
