Using Switch Logging

Switch Logging Overview

OmniSwitch AOS Release 6 Network Configuration Guide

page 46-5

Switch logging uses a formatted string mechanism to process log requests from switch applications. When 
a log request is received, switch logging compares the severity level included with the request to the sever-
ity level stored for the application ID. If there is a match, a log message is generated using the format 
specified by the log request and placed in the switch log queue. Switch logging then returns control back 
to the calling application.

You can specify the path to where the log file will be printed in the switch’s flash file system. You can 
also send the log file to other output devices, such as the console or remote IP address. In this case, the log 
records generated are copied to all configured output devices.

Switch logging information can be displayed and configured through CLI commands, WebView, and 
SNMP. The information generated by switch logging can be helpful in resolving configuration or 
authentication issues, as well as general errors.

Notes. Although switch logging provides complementary functionality to switch debugging facilities, the 
switch logging commands are not intended for use with low-level hardware and software debugging 
functions.

 command can be used to capture and save all switch logging configuration 

settings in a text file that can be viewed, edited, and used as a configuration file. See the “Working with 
Configuration Files” chapter of the OmniSwitch AOS Release 6 Switch Management Guide.
