        We have previously introduced How To Turn Off Prompt Messages On Huawei Switches.
        This document explains how to enable or disable automatic log popups on the console port of Cisco switches.
        Cisco switch logs are categorized into 8 severity levels, as listed below:

        The console port outputs logs of all severity levels by default.
        While these logs provide real-time device status and help with fault detection, scrolling messages often interrupt command input during configuration or inspection.
        Enable / Disable Console Logging
        You can control console log prompts through the following commands in global configuration mode:
        • To disable console logging:
            no logging console
        • To enable console logging:
            logging console
        By default, console logging applies to all severity levels.
        To display only logs of a specific severity or higher, use:
            logging console [severity_level]
        Note: These commands only affect log output to the console line, not other logging destinations.
        Related Configuration Notes
        • Before using console logging, ensure system logging is enabled:
            logging on
        • To check the current logging status (including console log settings), run in user EXEC mode:
            show logging
        • Even if console logging is disabled, logs remain buffered and can still be viewed using show logging.
        • To clear the internal log buffer:
            clear logging
