This only applies if they're using the Spanning Tree Protocol option
(otherwise there's no reason I'm aware of that making a switch change
would cause the problem to disappear, unfortunately).

set spantree portfast M/P enable

where M is the module and P is the port.

The switch will display a significant caution statement when the command
is issued, but it should only apply if you're attaching a switch or some
device that talks to the network like it's a switch (I think we have some
hosts like that, 802.1q aware load balancers).
