Configuring System Message Logging Chapter 23 Configuring System Message Logging Synchronizing Log Messages You can configure the system to 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 determine the maximum number of buffers for storing asynchronous messages for the terminal after which messages are dropped. When synchronous logging of unsolicited messages and debug command output is enabled, unsolicited device output is displayed on the console or printed after solicited device output is displayed or printed. Unsolicited messages and debug command output is displayed on the console after the prompt for user input is returned. Therefore, unsolicited messages and debug command output are not interspersed with solicited device output and prompts. After the unsolicited messages are displayed, the console again displays the user prompt. Beginning in privileged EXEC mode, follow these steps to configure synchronous logging: Step 1 Step 2 Step 3 Step 4 Command configure terminal line [console | vty] line-number [ending-line-number] logging synchronous [level severity-level | all] [limit number-of-buffers] end Purpose Enter global configuration mode. Specify the line to be configured for synchronous logging of messages. • Use the console keyword for configurations that occur through the switch console port. • Use the line vty line-number command to specify which vty lines are to have synchronous logging enabled. You use a vty connection for configurations that occur through a Telnet session. The range of line numbers is from 0 to 15. You can change the setting of all 16 vty lines at once by entering: line vty 0 15 Or you can change the setting of the single vty line being used for your current connection. For example, to change the setting for vty line 2, enter: line vty 2 When you enter this command, the mode changes to line configuration. Enable synchronous logging of messages. • (Optional) For level severity-level, specify the message severity level. Messages with a severity level equal to or higher than this value are printed asynchronously. Low numbers mean greater severity and high numbers mean lesser severity. The default is 2. • (Optional) Specifying level all means that all messages are printed asynchronously regardless of the severity level. • (Optional) For limit number-of-buffers, specify the number of buffers to be queued for the terminal after which new messages are dropped. The default is 20. Return to privileged EXEC mode. 23-6 Catalyst 2950 Desktop Switch Software Configuration Guide 78-14982-01
