getty repeating too quickly on port /dev/ttyu1 in messages

  • 1.  getty repeating too quickly on port /dev/ttyu1 in messages

    Posted 07-27-2021 08:45
    Good morning.
    I upgrade a 3400 from 20.1R1-S1  to 20.4 20.4R2-S1.6  this morning and I seen a lot of tty error logs after the reboot(136 lines in 50 minutes) .
    This could have been a fluke but   in case its not and is a odd artifact   as root do a kill -HUP 1 and that seemed to have addressed the issue.

    Jul 27 07:25:58 switch getty[17550]: %AUTH-3: login_tty /dev/ttyu1: Inappropriate ioctl for device
    Jul 27 07:25:58 switch init: %AUTH-1: getty repeating too quickly on port /dev/ttyu1, sleeping 30 secs

    at the shell as root
    switch:RE:0% kill -HUP 1

    I do have my auxiliary  com port
     auxiliary {
    port-type mini-usb;
