9.10 ibportstate
Enables querying the logical (link) and physical port states of an InfiniBand port. It also allows
adjusting the link speed that is enabled on any InfiniBand port.
If the queried port is a switch port, then ibportstate can be used to
• disable, enable or reset the port
• validate the port’s link width and speed against the peer port
