Setting SYSLOG Parameters
The CLI can use SYSLOG messages to communicate the following types of messages to a
SYSLOG server:
• Fatal – Provide information about events that caused the SSR 2000 to crash and reset.
• Error – Provide information about errors.
• Warning – Provide warnings against invalid configuration information and other
conditions that are not necessarily errors. This is the default.
• Informational – Provide informational messages such as status messages. The
SYSLOG messages that the SSR 2000 displays while booting the software and reading
the startup configuration file are examples of Informational messages.
The SSR 2000 writes the SYSLOG messages to a SYSLOG daemon on UDP port 514. You
can set the CLI to send all or only some of the message types. By default, the CLI sends
warning, error, and fatal messages but not informational messages to the specified
SYSLOG server.
Use the following procedure to specify the SYSLOG server and the types of messages you
want the CLI to log on the server.
