Configuring System Message Logging
Enabling and Disabling Sequence Numbers in Log Messages
Because there is a chance that more than one log message can have the same timestamp, you can display
messages with sequence numbers so that you can unambiguously refer to 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:
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.
This example shows part of a logging display with sequence numbers enabled:
000019: %SYS-5-CONFIG_I: Configured from console by vty2 (10.34.195.36)

You can limit messages displayed to the selected device by specifying the severity level of the message,
which are described in
