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.
Since you don't need encryption, aren't these more or less the same requirements as to transport dot1q tags within an existing vlan, that is, q-in-q? The foundry/brocade approach would be to override the frame tag on the entry and exit ports and declare those ports as access-ports (untagged to transport-vlan XYZ), thus transporting anything that comes in there via vlan XYZ to the destination. Or is LACP more low-level and can't be tricked to be relayed by playing with frame types?
