Will the 5660 route Jumbo Frames

[brian_ctl]

The physical interface supports Jumbo Frames:

config-giga-eth 0/2)#mtu

<60-9242>              - MTU (bytes)

But it looks like the IP interface does not:

config-giga-eth 0/2.1)#ip mtu

<68-1500>              - MTU (bytes)

I was advised by Adtran that all of their products including the 5660 with only do 1500 MTU on layer 3 / IP.  Any Jumbo Frame support is restricted to switching / L2 only.
