Auto Save on Crash or Rollover
Exception information for MASTER or standby units is stored in the flash:/TRACE_LOG_DIR directory. This
directory contains files that save trace information when there has been a task crash or timeout.
• On a MASTER unit, you can reach the TRACE_LOG_DIR files by FTP or by using the show file
command from the flash://TRACE_LOG_DIR directory.
• On a Standby unit, you can reach the TRACE_LOG_DIR files only by using the show file command
from the flash://TRACE_LOG_DIR directory.
NOTE: Non-management member units do not support this functionality.

Using the Show Hardware Commands
The show hardware command tree consists of commands used with the Aggregator switch.
These commands display information from a hardware sub-component and from hardware-based feature
tables.
NOTE
: Use the show hardware commands only under the guidance of the Dell Technical Assistance
Center.
• View internal interface status of the stack-unit CPU port which connects to the external management
interface.
EXEC Privilege mode
show hardware stack-unit {0-5} cpu management statistics
• View driver-level statistics for the data-plane port on the CPU for the specified stack-unit.
EXEC Privilege mode
show hardware stack-unit {0-5} cpu data-plane statistics
This view provides insight into the packet types entering the CPU to see whether CPU-bound traffic is
internal (IPC traffic) or network control traffic, which the CPU must process.
• View the modular packet buffers details per stack unit and the mode of allocation.
EXEC Privilege mode
show hardware stack-unit {0-5} buffer total-buffer
• View the modular packet buffers details per unit and the mode of allocation.
EXEC Privilege mode
show hardware stack-unit {0-5} buffer unit {0-1} total-buffer
