Exchange 2013 DAG, two nodes, a dedicated GBE network interface on each server for replication traffic, connected to a GBE switch, using a dedicated VLAN.

Is there any benefit to Exchange replication traffic in enabling Ethernet Jumbo Frames both on the server NICs and on the switch?

Is there any potential problem?

I'm not aware of any risks, but I'm not sure you'll see a lot of benefit, unless you know some quirks about your environment that you're not describing. My current client has a ~6500-mailbox organization, and a 3-node DAG, with the third node across a metro WAN link, I think 50 Mbit. Replication worked just fine. And that's under Ex2010 / Server 2K8 R2 - DAG is a tech that keeps getting better.

Unless you've done some benchmarking that shows you need the increased throughput from jumbo frames, I would simply, from a maintenance/manageability standpoint, keep it normal.
