Telnet Commands
-lb_mode mode Specify the loopback mode for source and
destination standard meanings. The default
mode is 5. The valid modes are:
•0 cable loopback
•1 plug loopback
•2 external loopback (SERDES)
•5 internal loopback (ASIC)
-fr_type type Specify the frame types to send. The default
type is 1. The valid types are:
•0 single frame
•1 spinFab frames
•2 spinFab 1 K frames
-extonly
enable
Specify 1 to enable external-test-only mode.
The default value is 0. This command
normally sends bursts of frames from each
port under test to every other port in the list.
In extonly mode backPort will send only one
burst of frames to each port from each
miniswitch-to-miniswitch link. This tests all of
the external connections with only K * N
frames instead of the N^^2 frames required in
the all to all mode.
This mode is intended to be used in
ESS/burn-in testing to optimize test time. This
command tests only the external connections
between each miniswitch and txdpath is used
to test the internal bloom-to-bloom paths. In
this mode, the test does not check all of the VC
allocation, so it should not be used for
software regression test.
Valid values are:
•0 Send frames from all ports to all
other ports.
•1 Send only one burst of frames to
each link.
