I have a 10G DAC cable, connecting 10G 82599 NIC ports in two FreeBSD machines back-to-back. When I bring down the interface in one machine, the interface link in the peer machine is NOT going down.
Network topology:
FreeBSD machine(M1) FreeBSD machine(M2)
10G NIC port <-------------10G DAC cable --------------------------> 10G NIC port
Register settings :
bit IXGBE_ESDP_SDP3 of register IXGBE_ESDP is set to disable tx laser, when tried to bring down the interface.
Any clues why interface on the peer is not brought down?
