In case of multiple channel adapters (CAs) or multiple ports without a CA/port being specified, a
port is chosen by the utility according to the following criteria:
1. The first ACTIVE port that is found.
2. If not found, the first port that is UP (physical link state is LinkUp).
Examples
1. Query the status of Port 1 of CA mlx4_0 (using ibstatus) and use its output (the LID – 3 in
this case) to obtain additional link information using ibportstate.
-G/--Guid Use GUID address argument. In most cases, it is the Port GUID. Example:
‘0x08f1040023’
-s/--sm_port Use <smlid> as the target lid for SM/SA queries
-C/--Ca Use the specified channel adapter or router
-P/--Port Use the specified port
-u/--usage Usage message
-t/--timeout Override the default timeout for the solicited MADs [msec]
<dest dr_path | lid | guid> Destination’s directed path, LID, or GUID.
<portnum> Destination’s port number
<op> [<value>] Define the allowed port operations: enable, disable, reset, speed, and
query
