Chapter 25 Configuring System Message Logging Configuring System Message Logging Command Step 3 logging host Step 4 logging file flash:filename [max-file-size [min-file-size]] [severity-level-number | type] Step 5 end Step 6 terminal monitor Step 7 show running-config Step 8 copy running-config startup-config Purpose Log messages to a UNIX syslog server host. For host, specify the name or IP address of the host to be used as the syslog server. To build a list of syslog servers that receive logging messages, enter this command more than once. For complete syslog server configuration steps, see the "Configuring UNIX Syslog Servers" section on page 25-10. Store log messages in a file in Flash memory. • For filename, enter the log message filename. • (Optional) For max-file-size, specify the maximum logging file size. The range is 4096 to 2147483647. The default is 4096 bytes. • (Optional) For min-file-size, specify the minimum logging file size. The range is 1024 to 2147483647. The default is 2048 bytes. • (Optional) For severity-level-number | type, specify either the logging severity level or the logging type. The severity range is 0 to 7. For a list of logging type keywords, see Table 25-3 on page 25-9. By default, the log file receives debugging messages and numerically lower levels. Return to privileged EXEC mode. Log messages to a nonconsole terminal during the current session. Terminal parameter-setting commands are set locally and do not remain in effect after the session has ended. You must perform this step for each session to see the debugging messages. Verify your entries. (Optional) Save your entries in the configuration file. The logging buffered global configuration command copies logging messages to an internal buffer. The buffer is circular, so newer messages overwrite older messages after the buffer is full. To display the messages that are logged in the buffer, use the show logging privileged EXEC command. The first message displayed is the oldest message in the buffer. To clear the contents of the buffer, use the clear logging privileged EXEC command. Use the logging event power-inline-status interface configuration command to enable and to disable logging of Power over Ethernet (PoE) events on specific PoE-capable ports. Logging on these ports is enabled by default. To disable logging to the console, use the no logging console global configuration command. To disable logging to a file, use the no logging file [severity-level-number | type] global configuration command. Synchronizing Log Messages You can synchronize unsolicited messages and debug privileged EXEC command output with solicited device output and prompts for a specific console port line or virtual terminal line. You can identify the types of messages to be output asynchronously based on the level of severity. You can also configure the maximum number of buffers for storing asynchronous messages for the terminal after which messages are dropped. 78-16156-01 Catalyst 3560 Switch Software Configuration Guide 25-5
