Usage
Information
One trace log message is generated for each command. No password information is saved to this file. A
command-history trace log is saved to a file after failover. Dell EMC Networking TAC analyzes this file to
help identify the root cause of it.
The timestamps display format of the show command-history output changes based on the
service timestamps log datetime configuration. The time format can be in uptime, local time or
UTC time.
If timestamp is disabled (no service timestamps log), the command history time format is shown
with timestamp defaults (service timestamps log datetime localtime) as in Example 4.
Example Example 1: Default configuration service timestamps log datetime or service
timestamps log datetime localtime
