[ofa-general] Re: [PATCH v2] infiniband-diags/scripts: Add 'ibcheckspeed' and 'ibcheckportspeed' to scripts

[Ira Weiny]

Also, iblinkinfo will report links which it finds capable of either faster or wider operation.  iblinkinfo checks both ends of the link as Hal mentions.  It reports this with output like.

Switch 0x0005ad0000092106 Cisco Switch SFS7000D:
...
           7    8[  ] ==( 4X 2.5 Gbps Active/  LinkUp)==>       8   12[  ] "MT47396 Infiniscale-III Mellanox Technologies" ( Could be 5.0 Gbps)
...

Also the portstatus console command in OpenSM will report links which are running at "reduced speed or width".  Although this does not check the remote port.

OpenSM $ help portstatus
portstatus [ca|switch|router]
summarize port status
   [ca|switch|router] -- limit the results to the node type specified
OpenSM $ portstatus
"ALL" port status:
   115 port(s) scanned on 9 nodes in 26 us
   85 down
   30 active
   32 at 4X
   22 at 2.5 Gbps
   8 at 5.0 Gbps
   2 at 10.0 Gbps

Possible issues:
   2 disabled

      0x0005ad0000092106 8 (Cisco Switch SFS7000D)
