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.
