portLoopbackTest
2
--slot number Specify the slot number on which the diagnostic will operate. The ports
specified will be relative to this slot number. The default is set to 0 and
designed to operate on fixed-port-count products.
-nframes count Specify the number of frames to send. The test will progress until the
specified number of frames has been transmitted on each port. The default
value is 10.
-lb_mode mode Specify the loopback mode for the test. By default, this test uses internal
loopback. Valid values are as follows:
1 Port Loopback (loopback plugs)
2 External (SERDES) loopback
5 Internal (parallel) loopback
-spd_mode mode Specify the speed mode for the test. This parameter is used only with Bloom
and Condor ASIC-based products, where it controls the speed at which each
port is operated. For 1 Gbit/sec-only products, it is ignored. The exact
operation of speed modes 5 through 8 depends upon the loopback mode
selected. When speed modes 5 through 8 are used with cables, they must be
connected even to odd or the test will fail.
0 Runs test at 1 Gbit/sec, 2 Gbit/sec, and 4 Gbit/sec.
1 Runs test at 1 Gbit/sec.
2 Runs test at 2 Gbit/sec (Bloom default).
4 Runs test at 4 Gbit/sec (Condor default).
For lb_mode set to 0 or 1, the following speed modes are available to test the speed negotiation:
3 Set all even ports' speed for autonegotiate; set all odd ports' speed for
1 Gbit/sec.
4 Set all even ports' speed for autonegotiate; set all odd ports' speed for
2 Gbit/sec.
5 Set all odd ports' speed for autonegotiate; set all even ports' speed for
1 Gbit/sec.
6 Set all odd ports' speed for autonegotiate; set all even ports' speed for
2 Gbit/sec.
For lb_mode set to 2 or 3, the following speed modes are available to test FIFO underrun.
3,5 Set all even ports' speed for 2 Gbit/sec; set all odd ports' speed for 1
Gbit/sec.
4,6 Set all even ports' speed for 1 Gbit/sec; set all odd ports' speed for 2
Gbit/sec.
-ports itemlist Specify a list of blade ports to test. By default, all of the blade ports in the
specified slot (--slot) are used. See itemList for more information.
Examples To run a functional test of a connection:
switch:admin> portloopbacktest -ports 1/10-1/20 -nframes 1 -lb_mode 1
