Chapter 32 Configuring System Message Logging
Configuring System Message Logging
You can access logged system messages by using the switch command-line interface (CLI) or by saving
them to a properly configured syslog server. The switch software saves syslog messages in an internal
buffer.
You can remotely monitor system messages by viewing the logs on a syslog server or by accessing the
switch through Telnet or through the console port.
