Diagnostics and Troubleshooting
The show diagnostics backplane-utilization Command Available
The show diagnostics backplane-utilization command is not supported on Alpine or Summit
switches. Though the command is available, there are no backplane utilization diagnostics available for
Alpine or Summit switches (PD2-130597218).
Spurious Message When system-down is Configured
If you configure the system health check alarm level for system-down and a fault is detected, the switch
is turned off but continuously logs the message Card in slot N is off line. You can ignore this message
(PD2-129386201).
The use configuration Command
When the switch is in minimum mode, the use configuration command has no effect on the backup
MSM (PD2-129133801).
Output of the show diagnostics Command
The output of the show diagnostics command for the CPU system might display negative numbers,
and the totals might not add up properly (PD2-128460401).
Configure Auto-Recovery to online or Alarm-Level to traps
If you configure the system health check auto-recovery to offline, save the configuration, and
configure the alarm-level to
log, a health check brings the module or switch offline regardless of how
many errors the health check detects. To avoid this, either configure auto-recovery to
online, or
configure alarm-level to
traps (PD2-124368101).
Error Count Not Accurate
If the switch is flooded with heavy traffic for more than 10 minutes, the CPU System field in the show
diagnostics
output is not accurate. The display reports up to 20 more errors (PD2-122738701).
Configuring Diagnostics Mode Off
If you configure diagnostics mode OFF, and then execute the unconfigure switch all command,
when the switch returns to active state the diagnostics mode is still set to OFF. The default diagnostics
mode should be
fastpost. To verify which diagnostics mode is set for the switch, use the show switch
command (1-97NL1).
Disable Remote Syslog Before Enabling IPARP Debug-Tracing
With remote syslog enabled, if you configure the IPARP debug-trace to level 2 or higher, the switch
hangs and is rebooted by the watchdog timer. To avoid this, disable the remote syslog prior to
configuring the debug-trace (PD2-110983505).
