Out-of-band Traffic Mirroring

Out-of-band traffic mirroring topology

• Mirrored traffic is captured on the ingress or egress leaf switch and carried on a separate set of links to a separate add-on mirror switch.
• One port is reserved on each fabric leaf and border leaf switch, and connected to the mirror switch through separate OOB cabling.
• EFA configures basic mirroring sessions and actions on fabric switches.
• Advanced configuration on the mirror switch is handled separately, not by EFA.
• Connectivity between the TAP (traffic access point) sink (a class or function designed to receive incoming events from another object or function.) and the mirror switch can be configured and customized separately through OOB mechanisms.
• Perform demultiplexing on sessions involving traffic access (TAP) points, using filtering on packet header fields in the sink application
• 100Gbps links are required between the mirror switch and each fabric switch.
• The mirror switch may be an 8720 or a specialized packet broker with advanced functions.
