I’ve seen optical transport gear be non-transparent in a few situations when 
using OTU2 vs OTU2e, but they turned out to be a bug.  If a L2 platform is
being used to front-end a router, you could be seeing slow protocols like
CDP/LLDP/LACP being consumed by that switch.  If you configure LLDP does it
pass end-to-end?
