When the switch reports xbar alarms, you can use the troubleshooting commands in Table 11-1 to collect
more information.
Table 11-1 Crossbar Alarm Troubleshooting Commands
Command Purpose
dspxbar <slot> <plane>
Displays the following general information about the
configuration of a switch plane (or switching fabric or crossbar):
• Number of the slot where the crossbar ASIC resides (7 or 8
for a MGX 8850 (PXM1E) node, 9, 10, 25, or 26 for a
MGX 8950 node).
• Selected switch plane or ASIC number. The range is 0 to 3.
If you do not specify a plane with this command, the default
value of 0 is used.
• Revision number of the ASIC.
• Status of the ASIC.The status is either failed or OK. If the
status is failed, the other ASICs must carry the switching
load, and the throughput of the switch falls below the
maximum. In this case, Cisco Systems recommends you
replace the card. The cell grant mode is always “Multicast
Preferred.”
• The “Resent Sframe Tic” is the rising edge of the clock.
“Sframe” refers to a switch frame.
