Claim of US Patent No. 9,323,627

1. A method comprising:
identifying a network connection between a first physical port operating in a first communication mode and a second physical
port operating in a second communication mode;

monitoring at least one count that identifies the number of block-sized transmission errors encountered by the first physical
port;

determining, based at least in part on the count that identifies the number of block-sized transmission errors encountered
by the first physical port, that the second physical port has experienced a fault condition;

in response to determining that the second physical port has experienced the fault condition, deactivating the network connection
to avoid dropping network traffic directed to the network connection.
