Backplane Health Check Diagnostic Results—Example 1.
Example 1 shows the report from one MSM, MSM-A in a BlackDiamond 6808 switch. If two MSMs are
in the chassis, both MSM-A and MSM-B are reported.

where:
Total Tx
Lists the total number of health check packets transmitted by the CPU to an I/O module.
The statistics for any I/O module will always be zero, because I/O modules do not generate
health check packets (the switch sends health check packets from the MSM to the I/O
modules only, not in the reverse direction).

Total Rx
Lists the total number of health check packets received on an I/O module and counted by
the CPU. Again, this counter will always read zero for any I/O module.

Total miss
Lists the total number of missed health check packets for any I/O module. On the MSM, the
number reflected is shown under the backplane port number corresponding to a given I/O
module.

Error Pkt
Lists the total number of corrupted health check packets counted by the CPU on a given
backplane port.

Diag fail
Lists the total number of diagnostic packets that failed from the I/O module to the CPU.
Last fail time
Lists the date and time of the previous corrupted or missed health check packet.
