MACSec across WAN/MAN

[Mark Williams]

Hi.

Has anyone had any experience with configuring MACSec between two routers/switches that are the end points of a WAN/MAN circuit?

We plan on using two 3750-X as the routers on a circuit that is 1Gb/s EoSDH.

The thing I am worried about is that the carrier will not be able to transport the frames.

So.. is there anything I need to consider when using MACSec on WAN/MAN circuits?

Especially for EoSDH and L2 MPLS VPNs type links.

Did you ever find a solution to this issue? We are also trying to implement MACSEC over SDH and though the carrier says we shouldn't have any issues we cannot get it to function. 

Thanks-
