Enabling And Disabling Sequence Numbers In Log Messages; Defining The Message Severity Level - Cisco WS-C3550-12G Software Configuration Manual

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)

Defining the Message Severity Level

You can limit messages displayed to the selected device by specifying the severity level of the message,
which are described in
Beginning in privileged EXEC mode, follow these steps to define the message severity level:
Command
Step 1
configure terminal
Step 2
logging console level
Step 3 logging monitor level
Step 4
logging trap level
Step 5
