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 permanently 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  net‐
              plan(5) format.

       --timeout TIMEOUT
              Wait  for TIMEOUT seconds before reverting.  Defaults to 120 seconds.  Note that some network con‐
              figurations (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 net‐
       work configuration has in fact been reverted.

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