Cisco Systems 3560 Manual De Usuario

This example shows part of a logging display with the service timestamps log uptime global 
configuration command enabled:

00:00:46: %LINK-3-UPDOWN: Interface Port-channel1, changed state to up 

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.

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

procedure is optional.
