[c-nsp] How can I increase Ethernet MTU?

I have a network of about twenty C3560X switches switching IP-only traffic.

Soon we will be enabling MPLS on some routers connected to this
network, so the switches will have to handle frames with the MTU
larger than the default 1500 bytes.

How do I configure the switches to pass frames with MTU=1600, if
possible, without disrupting the service? 

I will be grateful for a link to some good howto.
