Notes about the output above:
The ports’ states are:
• Port 1 - InfiniBand, is in PORT_INIT
state
• Port 2 - Ethernet is in PORT_ACTIVE
state
The port state can also be obtained by running the
following commands:
# cat /sys/class/infiniband/mlx4_0/ports/
1/state 2: INIT
# cat /sys/class/infiniband/mlx4_0/ports/
2/state 4: ACTIVE
#
The link_layer parameter shows that:
• Port 1 is InfiniBand
• Port 2 is Ethernet
Nevertheless, Port 2 appears in the list of
the HCA's ports.
The link_layer of the two ports can also be obtained
by running the following commands:
# cat /sys/class/infiniband/mlx4_0/ports/
1/link_layer InfiniBand
# cat /sys/class/infiniband/mlx4_0/ports/
2/link_layer Ethernet
