Syslog logging

Configure logging

Given a syslog server listening on default port 514/udp, let's configure our Cisco to send messages over the syslog protocol:

Switch(config)#logging 192.168.1.2
Switch(config)#logging trap 6
Switch(config)#end

Notice that logging levels (logging trap) are defined as follows:

• 0: Emergency
• 1: Alert
• 2: Critical
• 3: Error
• 4: Warning
• 5: Notice
• 6: Informational
• 7: Debug
