What to do next
Collect the output of the show tech ncs1k detail command if any the following conditions occur:
• Equipment fail alarm is raised.
• Stateful mode is disabled for an unknown reason.
Monitoring Headless Statistics
In the headless mode, the data path and statistics are maintained for at least 72 hours. These statistics are
automatically cleared during the next reload or CPU-OIR operation.
Use this procedure to display the statistics collected during the last headless operation.
show controllers controllertype R/S/I/P headless-stats
Displays the statistics collected during the last headless operation. The collected statistics are preserved for a slice until
the hardware module configuration is removed or changed on that slice.
Example:
The following example displays the statistics collected for the Ethernet controller during the last headless operation.
