Enabling and Disabling Sequence Numbers in Log Messages

Because there is a chance that more than one log message can have the same time stamp, you can display
messages with sequence numbers so that you can unambiguously see a single message. By default,
sequence numbers in log messages are not displayed.
Beginning in privileged EXEC mode, follow these steps to enable sequence numbers in log messages.
This procedure is optional.
Command
Step 1 configure terminal
Step 2
service sequence-numbers
Step 3 end
Step 4 show running-config
Step 5
copy running-config startup-config
To disable sequence numbers, use the no service sequence-numbers global configuration command.
