Logging Messages to a UNIX Syslog Server

To log messages to a syslog server host, use the logging host global configuration command. The full
syntax of this command follows:
The logging host command identifies a syslog server host that is to receive logging messages. The
ip-address argument is the IP address of the host. By issuing this command more than once, you build a
list of syslog servers that receive logging messages.
The no logging host command deletes the syslog server with the specified address from the list of
syslogs.

Limiting Messages to a Syslog Server

To limit the number of messages sent to syslog servers, use the logging trap router configuration
command. The full syntax of this command follows:
The logging trap command limits the logging messages sent to syslog servers to logging messages with
a level up to and including the specified level argument.
To send logging messages to a syslog server, specify its host address with the logging host command.
The default trap level is informational.
The no logging trap command returns the trap level to the default.
The current software generates the following categories of syslog messages:
