Chapter9 Troubleshooting Commands dspxbaralm
Example
Display the severity of crossbar alarms. On the card in slot 7, crossbars 1 and 2 show errors. In such a case as two crossbars showing majo r er r ors , a ca rd in a slot rather than a switch A S I C may b e a t fa ult. Therefore, you could execute dspcds to see if service module has an alarm or dspxbarerrcnt for switch ASICs 1 and 2 to see if each ASIC is showing si mil ar da ta for the same ca rd s lot. You could also execute dspcdalm on the PXM45.

Slot Plane Severity
---- ----- --------
7 0 None
7 1 Major
7 2 Major
8 0 None
8 1 None
8 2 None
Subsequent execution of dspxbarerrcnt shows the slot number (or link) and types of errors.
Note the large number of errors in slot 12. 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.
