Description
Use this command to verify the TXA, TXD, and CMI data paths between the
ASICs. This is done by configuring all of the ports for internal loopback and
sending a frame from each quadrant to all other port on the switch. The frame
starts from the CPU and is transmitted by the first port which also receives the
frame and deposits it in central memory. The second port then reads the frame
from central memory using its own TXA and TXD path. The frame is then looped
back one more time and is sent back to the CPU where it is compared with the
transmitted data.
Only one frame is transmitted and received at a time. An external cable is not
required to run this test. The port sending frames displays a flickering green LED
while the test is running. The test method is as follows:
1. Set all ports present for parallel loopback. Then for each pair of source
quadrants and destination ports
2. Set up source port to route frames to destination port and destination port to
route frames to CPU.
3. Transmit frame F via source port.
4. Pick up the frame from destination port.
5. Check if any of the 8 statistic error counters are non-zero:
ENC_in, CRC_err, TruncFrm, FrmTooLong, BadEOF, Enc_out,
BadOrdSet, DiscC3.
