Using the SpinFab and portTest commands 10 Using the SpinFab and portTest commands The spinFab command is an online diagnostics command to verify the ISL links between switches at the maximum speed. It is done by setting up the routing functionality in the hardware such that the test frames received by E_Port are retransmitted on the same E_Port. Several frames are then sent to the port attached to each active E_Port specified. These frames are special frames which never occur during normal traffic and the default action for such frames is to route them back to the sender. These frames are circulated between switches until the test stops them. CAUTION During the spinFab testing, the switch remains in normal operation. However, some performance degradation occurs due to the ISL links being saturated with the test frames. This test should be run with caution on a live fabric. Table 18 lists the supported ports for the specified version of Fabric OS when using the spinFab command.

Using the SpinFab and portTest commands
The
spinFab
command is an online diagnostics command to verify the ISL links between switches
at the maximum speed. It is done by setting up the routing functionality in the hardware such that
the test frames received by E_Port are retransmitted on the same E_Port. Several frames are then
sent to the port attached to each active E_Port specified. These frames are special frames which
never occur during normal traffic and the default action for such frames is to route them back to
the sender. These frames are circulated between switches until the test stops them.
CAUTION
During the spinFab testing, the switch remains in normal operation. However, some performance
degradation occurs due to the ISL links being saturated with the test frames. This test should be
run with caution on a live fabric.
