This document describes the extension of an existing feature allowing DMF to use intra-fabric L2GRE tunnels.These tunnels enable forwarding unmodified production network packets over intermediate L3 networks used by DMF, which can now forward packets with Arista Networks Timestamp headers across L2GRE tunnels defined on EOS switches.

Timestamping DMF-8.5.0 L2GRE Tunnel

Previously, Tap Aggregation and Mirror to GRE timestamping only supported timestamping packets in International

Tap Aggregation Timestamping 4.22.0F

Timestamping is an important tool for network engineering and performance analysis. The timestamp can be applied to a packet as either an inserted header or replacing the source MAC address of the original packet. Timestamps are recorded on ingress and applied on egress.
