Table 26 lists the ibdiagnet output files that are placed under /var/tmp/ibdiagnet2.
--ber_test : Provides a BER test for each port. Calculate
BER for each port and check no BER value
has exceeds the BER threshold.
(default threshold="10^-12").
--ber_use_data : Indicates that BER test will use the received
data for calculation.
--ber_thresh <value> : Specifies the threshold value for the BER
test. The reciprocal number of the BER should
be provided. Example: for 10^-12 than value
need to be 1000000000000 or 0xe8d4a51000
(10^12).If threshold given is 0 than all
BER values for all ports will be reported.
--extended_speeds <dev-type> : Collect and test port extended speeds counters.
dev-type: (sw | all).
--pm_per_lane : List all counters per lane (when available).
--ls <2.5|5|10|14|25|FDR10> : Specifies the expected link speed.
--lw <1x|4x|8x|12x> : Specifies the expected link width.
-w|--write_topo_file <file name>: Write out a topology file for the discovered
topology.
-t|--topo_file <file> : Specifies the topology file name.
--out_ibnl_dir <directory> : The topology file custom system definitions
(ibnl) directory.
--screen_num_errs <num> : Specifies the threshold for printing errors
to screen.
(default=5).
--smp_window <num> : Max smp MADs on wire. (default=8).
--gmp_window <num> : Max gmp MADs on wire. (default=128).
--max_hops <max-hops> : Specifies the maximum hops for the discovery
process.
(default=64).
-V|--version : Prints the version of the tool.
-h|--help : Prints help information (without plugins
help if exists).
-H|--deep_help : Prints deep help information (including plugins
help).
