Overview

The Dell Networking OS tracks changes in the system using event and error messages.
By default, Dell Networking OS logs these messages on:
 
  • the internal buffer
  • console and terminal lines
  • any configured syslog servers



Enable Logging

 
Log messages in the internal buffer:
 
All error messages, except those beginning with %BOOTUP (Message), are log in the  internal buffer.
For example, %BOOTUP:RPM0:CP %PORTPIPE-INIT-SUCCESS: Portpipe 0 enabled

                             
               
To send system messages to a specified syslog server, use the following command.


 
Command Parameters
console# configure Enter configuration mode.
console(conf)# logging 192.168.1.1
 		 Set IP address or hostname identifying the external syslog server to send log output.  (Optional) UDP and TCP port designation


You can configure up to eight syslog servers.
 
 

Disable Logging

Command Parameters
console# configure Enter configuration mode.
console(conf)# no logging on Disable all logging except to the console.
console(conf)# no logging buffer Disable logging to the logging buffer.
console(conf)# no logging monitor Disable logging to terminal lines.
console(conf)# no logging console Disable console logging.
 
 



Change Logging Settings

You can change the default settings of the system logging by changing the severity level and the storage location.
 
The default is to log all messages up to debug level, that is, all system messages. By changing the severity level in the logging commands, you control the number of system messages logged.

 

 

NOTE: In order to properly log debug output to syslog server you must enable a trap with the debugging severity=7 level. Even if it is set to buffered it is still not sent to the syslog server unless a trap is enabled properly.
