[cursixx]

When creating or removing LAGG interfaces I receive the following errors.

Do you get that when you open the page or when you try to save the new entry or make some other change?

Can you share the contents of the <laggs>...</laggs> section of your config.xml file?

[cursixx]

@jimp Opening the LAGG edit page works but when saving it returns the php error above but seems to create the LAGG. I also tried to edit it and that also returns the php error but changes the config. When I try to delete a LAGG interface it returns the php error but the LAGG interface is not deleted.

Here is the lagg config

<laggs>
	<lagg>
		<members>ixl4,ixl6</members>
		<descr></descr>
		<laggif>lagg0</laggif>
		<proto>lacp</proto>
		<lacptimeout>slow</lacptimeout>
		<lagghash>l2,l3,l4</lagghash>
	</lagg>
	<lagg>
		<members>ixl3,ixl5</members>
		<descr></descr>
		<laggif>lagg1</laggif>
		<proto>lacp</proto>
		<lacptimeout>slow</lacptimeout>
		<lagghash>l2,l3,l4</lagghash>
	</lagg>
</laggs>

OK, it wasn't the <lagg> section of the config that was the problem, but the <vlans> list being empty.

I put in a fix: https://github.com/pfsense/pfsense/commit/960388e0dbd4ab2c4ac96c8709dcdcb27460b1bc
