crossPortTest
The
crossPortTest
command which is used to check the communication
between different interface module ports on the same Switch. The Switch’s
G_Port and FL_Port ASICs, CPU, the interface cards and their GBIC modules
are tested.
The command can be run on a Switch that is online or offline. If the Switch is
online, only the ports that are cross connected are tested. If the Switch is
offline this test must have all ports on the Switch interconnected. See Figure
B-43.
Any port combinations may be cross connected as long as you connect
G_Ports to G_Ports and FL_Ports to FL_Ports.
This test passes data between two ports on the Switch. This test verifies the
data integrity by using the CPU to compare the data sent to the data received.
All optical paths, including GBICs and cables are exercised in this test.
