Example
Display the crossbar error counters for switch ASIC 2 in slot 7. The Node Alarm field of the display
shows the errors have resulted in a critical alarm. A large number of errors have occurred in the slot 12
link. Many of the errors are parity or CRC related, but the one error that is most serious is loss of sync.
With a loss if sync between the service module and the switching fabric, many other, comparatively less
significant errors are possible.
Note at the bottom of the display a message about multipliers for large numbers of errors. Because the
display can accommodate a finite number of errors without being distorted, a K (for 1000) and M (for
1000000) multiplier may be necessary, as this example shows.
