System Log
The router can log significant system events (SYSLOG). The SYSLOG can be maintained locally on the router and can also be sent to a remote SYSLOG server.
To activate:
The router must be configured to enable the output of SYSLOG messages via the syslog enable command.
The Management Controller Card (MCC) always has SYSLOG enabled.
An IP address (loopback or remote) must be supplied.
The SYSLOG can also be captured by a remote SYSLOG server running the UNIX daemon syslogd or an equivalent program. It is necessary to know the IP address where the syslogd resides and the UDP port number the syslogd is using.
The advantage of using a remote SYSLOG server is that ALL events will be maintained upon restart of the router. The local SYSLOG is cleared upon restart.
Events are classified by severity level and the system administrator can specify the minimum severity to be logged.
