Failure vty login messages appearing repeatedly

    Hi,

    I tried to access the router via the console port via putty and wanted to view the running configurations but these messages about MSR3012 LOGIN/5/LOGIN_FAILED: VTY failed to login from 77.235.140.51 appeared on the putty screen 3 times and another message about MSR3012 LOGIN/5/LOGIN_FAILED: VTY failed to login from 189.80.93.238 appears more than 20 times on the screen. How do I stop the displaying of these messages? It seems like there are brute-force attacks on the router.  It makes my intention to view the running configurations and other implementations difficult. 

    Appreciate any solutions. 

     

    Thank You.

    Hi @Novis1 !

    'undo terminal monitor' is the command that will stop displaying log messages in the console session. Execute it from the user-view (that view with <> signs around the hostname)

    Hi @Ivan_B 

    Thanks, I will try that command out when I get back to the office.
