Troubleshooting the BPX Switch
Troubleshooting the BPX Switch
This section describes basic troubleshooting steps to be taken for some of the more obvious node failures
(see Table 28-1). This is not an exhaustive set of procedures, and does not take into account any of the
diagnostic or network tools available to troubleshoot the BPX switch. For information on commands and
usage, refer to the
Cisco WAN Switching Command Reference
.
Caution
Do not perform any disruptive tests or repairs to the BPX switch on your own. Before proceeding
with troubleshooting, call Cisco Customer Service so they can provide you with assistance in
locating the fault and provide repair information.
General Troubleshooting Procedures
The BPX switch runs self-tests continuously to ensure proper function. When the node finds an error
condition that affects its operation, it downs the card or trunk affected. It then selects a standby card or
alternate trunk if one is available.
The FAIL indicators on the cards indicate that the system has found these cards defective in some mode,
and now considers them as failed cards. Use Table 28-1
to find the cause and obtain the information on
replacing the failed component.
Caution
Never remove the active BCC until the standby BCC has entered the Standby mode. Using the
dspcd
command is the only reliable way to determine that the standby BCC has finished updating and has
entered the Standby mode.
Caution
When using Table 28-1
for troubleshooting, call Cisco Customer Service before performing any
disruptive testing or attempting to repair the BPX switch. This ensures that you have isolated the
correct problem area. It also enables Cisco Customer Service to provide assistance in performing the
necessary procedures.
Warning
Contact Cisco Customer Service before attempting to replace fuses on backplane.
