Chapter 32 Logs Screens Syslog Logs There are two types of syslog: event logs and traffic logs. The device generates an event log when a system event occurs, for example, when a user logs in or the device is under attack. The device generates a traffic log when a "session" is terminated. A traffic log summarizes the session's type, when it started and stopped the amount of traffic that was sent and received and so on. An external log analyzer can reconstruct and analyze the traffic flowing through the device after collecting the traffic logs. Table 196 Syslog Logs LOG MESSAGE DESCRIPTION Event Log: Mon dd hr:mm:ss hostname src="" dst="" msg="" note="" devID="" cat="" This message is sent by the system ("RAS" displays as the system name if you haven't configured one) when the router generates a syslog.

The "devID" is the MAC address of the router's LAN port. The "cat" is the same as the category in the router's logs.
