Description Gurpreet Singh 2023-04-18 02:09:52 UTC

Description of problem:
 

With an increasing number of network functions implemented as VNFs and acting as a transit point for the bulk of the network traffic, support for remote port mirroring to third-party analyzers for troubleshooting, billing, and other management activities are paramount. 

 

Port Mirroring support from a source on an OVN compute node to a destination that may or may not be an OVN compute node
Traffic from the source is replicated and mirrored traffic is GRE encapsulated for mirroring the destination
Port Mirroring Use Cases

(1) Remote Port Mirroring using GRE tunnel (Core OVN support BZ - https://bugzilla.redhat.com/show_bug.cgi?id=2097289)
(2) Remote port mirroring using ERSPAN

Refer to https://issues.redhat.com/browse/OSP-21638 for more details.
