NAME
       netplan-try - try a configuration, optionally rolling it back

SYNOPSIS
       netplan [--debug] try -h | --help

       netplan [--debug] try [--config-file CONFIG_FILE] [--timeout TIMEOUT]

DESCRIPTION
       netplan  try takes a netplan(5) configuration, applies it, and automatically rolls it back
       if the user does not confirm the configuration within a time limit.

       A configuration can be confirmed or rejected interactively or by sending  the  SIGUSR1  or
       SIGINT signals.

       This  may be especially useful on remote systems, to prevent an administrator being perma-
       nently locked out of systems in the case of a network configuration error.

OPTIONS
       -h, --help
              Print basic help.

       --debug
              Print debugging output during the process.

       --config-file CONFIG_FILE
              In addition to the usual configuration, apply CONFIG_FILE.  It must be a YAML  file
              in the netplan(5) format.

       --timeout TIMEOUT
              Wait  for  TIMEOUT  seconds  before reverting.  Defaults to 120 seconds.  Note that
              some network configurations (such as STP) may take over a minute to settle.

KNOWN ISSUES
       netplan try uses similar procedures to netplan apply, so some of the  same  caveats  apply
       around virtual devices.

       There  are  also  some  known bugs: if netplan try times out or is cancelled, make sure to
       verify if the network configuration has in fact been reverted.

       As with netplan apply, a reboot should fix any issues.  However, be sure  to  verify  that
       the config on disk is in the state you expect before rebooting!
