HP StorageWorks 8B - FC Entry Switch Reference Manual page 255

Operands This command has the following operands:
nmegs
gbic_mode
lb_mode
spd_mode
Note:
Fabric OS Reference
Specify the number of million frames per port to execute this test. If omitted, the
default value is 0xfffffffe. This operand is optional.
Specify 1 to activate GBICmode, where only ports containing GBICs are tested.
Specify 0 to deactivate GBICmode. This operand is optional.
If this operand is not specified, the test will run with the GBICmode set for the
switch. You can set GBICmode as an operand or by using the setgbicmode
command.
Specify the loopback mode. The default value is 0. Valid values are:
0 - cable mode, tests M->N connections only
1 - for singleportalso mode, tests M->N and M->M connections
2 - for external loopback mode
5 - for internal loopback mode
Specify the speed of the connection to test. This operand is optional. Valid values
are 0 through 6 where:
0 - Auto negotiate
This will result in 1G for HP Brocade 2400 and 2800 switches. This option
initiates a negotiation cycle that will exercise more of the software and SFP
operation than specifying mode 1 or 2. If this mode fails and the fixed modes
pass, then it is likely that the automatic speed selection and filtering circuitry in
the SFP is bad.
1 - 1GB
Force speed to 1G with no negotiation.
2 - 2GB
Force speed to 2G with no speed negotiation. This option is valid only for
switches that support 2G connections.
3 - odd ports 1g, even ports 1G
4 - odd ports 2g, even ports 1G
This option is valid only for switches that support 2G connections. This test
mode requires lb_mode 1 and M->M loopback plugs, or lb_mode 0 and cable
connections with even to even and odd to odd connected cables.
When run with lb_mode1 and M->M plugs, it will test the speed translation
circuitry in the ASIC (fifo underrun avoidance).
5 - even ports 1G, odd ports Auto negotiate
6 - even ports 2G, odd ports Auto negotiate
This option is valid only for switches that support 2G connections. For useful
results this test must be run with lb_mode 0 and cables connected from even to
odd ports.
If you wish to specify a single operand, the others may become required, because operands
are identified by position. For example, if you want to specify a gbic_mode value, you must
also specify an nmegs value as well.
