spinFab
Test for Cascaded switch ISL links.
Synopsis
spinFab [ nMillionFrames [, ePortBeg [, ePortEnd [, setFail]]]]
Availability
admin
Description
Used to verify the intended functional operation of the ISL links between switches at the maximum
speed of 2Gbps by setting up the routing hardware such that test frames received by each E_port
retransmitted on the same E_port. Several frames are then sent to the neighbor port attached to each
active E_port specified. Since the default action for such frames (which never occur for normal
traffic) is to route them back to the sender, the frames that are sent in this manner will circulate until
the test stops them.
The frames are continuously transmitted and received in all ports in parallel. The port LEDs flicker
green rapidly while the test is running. While the frames are circulating the RX frame count and
port CRC and encoder error statistics will be monitored and errors will be generated if a port stops
or a low level error occurs. Every one million frames the circulating frames will be captured to
verify that they are still circulating and that they are still in-order. In this manner the entire path to
the remote switch may be verified.
The switch will remain in normal operation while this test is running, however some performance
degradation will occur due to the ISL links being saturated with test frames. Because of this you
should use caution when running this test on live fabrics, consider only testing one ISL link at a
time, and do not run the tests for extended periods of time.
This test is best combined with the online crossPorttest for ISL link failure isolation. If this test
fails, replace the cable with a loop-back plug and run crossport test to verify the local switch and
GBIC. If these pass then the fault lies in the cable or remote switch/GBIC.
The frames are continuously transmitted and received in all ports in parallel. The port LEDs flicker
green rapidly while the test is running.
When this command detects failure(s), the test may report one or more of the following error
messages:
1.
DIAG-INIT
2.
DIAG-PORTDIED
3.
DIAG-XMIT
4.
DIAG-PORTSTOPPED
5.
DIAG-ERRSTATS
6.
DIAG-ERRSTAT
Operands
This command has the following operands:
nMillionFrames
The number of million frames per port to execute this test. If omitted, the default
value used is 100. This operand is optional.
ePortBeg
First port to test, if omitted 0 will be used. This operand is optional.
