Hi all,
 
I need to transparently (especially LACP frames) transport a gigabit ethernet link with at least 1500 MTU over either IP or Ethernet. Jumbo frames are enabled on the L2 transport backbone. While I need "full" (some encap overhead will be acceptable) GigE wire speed, encryption is unnecessary.
 
Can anyone suggest a product -ideally some low-maintenance, high-reliability, perhaps ASIC-based hardware- that can do this?
