MPLS MTU command

I need to change the MTU on a router 7507 interface (VIP4-80 card with PA-2FE) using the "mpls mtu 1508", but it is on a production network, so I need to know:

Does this command cause the router to reset the FE ports? or the VIP card? or everything is transparent to the router?

Please let me know because I have to do it ASAP.

Regards

Re: MPLS MTU command

"mpls mtu" or "tag-switching mtu" will not reset the VIP or the Interface (based on personal experience on 75xx series running 12.0 (23) Service Provider IOS) . You don't have to be concerned with resets. Obviously it has the potential to impact your MPLS traffic but increasing it can only help your cause. It certainly won't make thing worse. Good luck.
