Does modifying port parameters ((MTU, Auto-Negotiation, Duplex, Speed) is disruptive?

Does modifying port parameters (MTU, Auto-Negotiation, Duplex, Speed) is disruptive? If so why? The ports are part of an interface group. One port is up and the other port part of the ifgrp is down.

I always evauate all lifs on any port/ifgrp/vlan i'm messing with,  just move them back when you're finished.  

There's a blip for sure when you mess with MTU,  can't recall off the top of my head on the others.  But when in double,  just move the lif(s) off.

Thank you so much. In this case, we are not going to change the MTU. But will ensure that no lifs are hosted during this change.

You can still proably do it non-disruptivly.    Just move your lifs around.
