The frames are continuously transmitted and received to 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 are
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.
Note: When trunk groups are present, then entire trunk group must be included in the
range of ports to test or false failures may occur. If multiple ISL links are present
between two switches that support trunking then it is likely that trunk groups are present
and all ports between the two switches should be tested at the same time.
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 loopback plug and run
crossporttest to verify the local switch and SFP. If these tests pass then the
fault lies in the cable or remote switch/SFP.
The frames are continuously transmitted and received in all ports in parallel. The
port LEDs flicker green rapidly while the test is running.
