<H2>NAME</H2>
<P>
netplan-try - try a configuration, optionally rolling it back
<A NAME="lbAC">&nbsp;</A>
<H2>SYNOPSIS</H2>
<P>
netplan [-debug] try -h | -help
<P>
netplan [-debug] try [-config-file
CONFIG_FILE] [-timeout TIMEOUT]
<A NAME="lbAD">&nbsp;</A>
<H2>DESCRIPTION</H2>
<P>
netplan try takes a <A HREF="/cgi-bin/man/man2html?5+netplan">netplan</A>(5) configuration,
applies it, and automatically rolls it back if the user does not confirm
the configuration within a time limit.
<P>
A configuration can be confirmed or rejected interactively or by sending
the SIGUSR1 or SIGINT signals.
<P>
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.

<H2>OPTIONS</H2>
<DL COMPACT>
<DT id="1"><B>-h, -help</B>
<DD>
Print basic help.
<DT id="2"><B>-debug</B>
<DD>
Print debugging output during the process.
<DT id="3"><B>-config-file </B>CONFIG_FILE
<DD>
In addition to the usual configuration, apply CONFIG_FILE.
It must be a YAML file in the <A HREF="/cgi-bin/man/man2html?5+netplan">netplan</A>(5) format.
<DT id="4"><B>-timeout </B>TIMEOUT
<DD>
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.
</DL>
<A NAME="lbAF">&nbsp;</A>
<H2>KNOWN ISSUES</H2>
<P>
netplan try uses similar procedures to netplan
apply, so some of the same caveats apply around virtual devices.
<P>
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.
<P>
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!
