What Factors Should Be Considered When Configuring Logging? 
Dell recommends that network administrators deploy a syslog server in their 
network and configure all switches to log messages to the syslog server. Switch 
administrators should also consider enabling persistent logging on the switch.
Default Log Settings
System logging is enabled, and messages are sent to the console (severity 
level: warning and above), and RAM log (severity level: informational and 
above). Switch auditing, CLI command logging, Web logging, and SNMP 
logging are disabled. By default, no messages are sent to the log file that is 
stored in flash, and no remote log servers are defined. 
Email alerting is disabled, and no recipient email address is configured. 
Additionally, no mail server is defined. If you add a mail server, by default, no 
authentication or security protocols are configured, and the switch uses TCP 
port 25 for SMTP.
After you enable email alerting and configure the mail server and recipient 
email address, log messages with a severity level of emergency and alert are 
sent immediately with each log message in a separate mail. The email subject 
is “Urgent Log Messages.” Log messages with a severity level of critical, error, 
and warning are sent periodically in a single email. The email subject is “Non 
Urgent Log Messages.” Messages with a severity level of notice and below are 
not sent in an email.
