where lid is the LID of the node in the fabric, and port is the port of the node.
For example:
# ibportstate 15 23 reset
Initial PortInfo:
# Port info: Lid 15 port 23
LinkState:.......................Down
PhysLinkState:...................Disabled
LinkWidthSupported:..............1X or 4X
LinkWidthEnabled:................1X or 4X
LinkWidthActive:.................4X
LinkSpeedSupported:..............2.5 Gbps or 5.0 Gbps or 10.0 Gbps
LinkSpeedEnabled:................2.5 Gbps or 5.0 Gbps or 10.0 Gbps
LinkSpeedActive:.................2.5 Gbps
After PortInfo set:
# Port info: Lid 15 port 23
LinkState:.......................Down
PhysLinkState:...................Disabled
After PortInfo set:
# Port info: Lid 15 port 23
LinkState:.......................Down
PhysLinkState:...................PortConfigurationTraining

15.2.4 Set Port Speed
You can manually set the speed of a single port to help determine symbol error
generation. The ibportstate command can set the speed to 2.5, 5.0, or 10.0 GB/sec.
On the command-line interface (CLI), run the following command:
# ibportstate lid port speed <value>
where lid is the LID of the node in the fabric, port is the port of the node, and
<value> is the speed you want to set.
Note:
Adding speed values enables either speed. For example, speed 7 is 2.5, 5.0,
and 10.0 GB/sec.
For example:
# ibportstate 15 23 speed 1
Initial PortInfo:
# Port info: Lid 15 port 23
LinkSpeedEnabled:................2.5 Gbps or 5.0 Gbps or 10.0 Gbps
After PortInfo set:
# Port info: Lid 15 port 23
LinkSpeedEnabled:................2.5 Gbps
# ibportstate 15 23 speed 7
Initial PortInfo:
# Port info: Lid 15 port 23
LinkSpeedEnabled:................2.5 Gbps
After PortInfo set:
# Port info: Lid 15 port 23
LinkSpeedEnabled:................2.5 Gbps or 5.0 Gbps or 10.0 Gbps
