# smpquery portinfo lid port
where:
lid is the LID of the node.
port is the port of the node.
For example, to see detailed information about port 8 on the switch with LID 24, type:
# smpquery portinfo 24 8 # Port info: Lid 24 port 8 Mkey:............................0x0000000000000000 GidPrefix:.......................0x0000000000000000 Lid:.............................0x0000 SMLid:...........................0x0000 CapMask:.........................0x0 DiagCode:........................0x0000 MkeyLeasePeriod:.................0 LocalPort:.......................8 LinkWidthEnabled:................1X or 4X LinkWidthSupported:..............1X or 4X LinkWidthActive:.................4X LinkSpeedSupported:..............2.5 Gbps or 5.0 Gbps or 10.0 Gbps LinkState:.......................Active PhysLinkState:...................LinkUp LinkDownDefState:................Polling ProtectBits:.....................0 LMC:.............................0 . . .
