more information.
Table 9-4 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
Cisco MGX 8850 node, 9, 10, 25, or 26 for a Cisco 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.
dspxbaralm Shows whether a crossbar alarm is minor, major, or critical. The display
shows status on both the active and standby PXM45.
