Hello @jnliujie,

Thanks! It looks like a bug, could you create a bug report on the https://phabricator.vyos.net/
I can propose some improvements, like checking is /dev/serial/ exists
https://github.com/vyos/vyos-1x/blob/current/interface-definitions/service_console-server.xml.in#L16
And change to

<script>if [ -d "/dev/serial" ]; then ls -1 /dev/serial/by-bus; fi</script>

Ok, Let me just check. Thank you…
