Question

A network engineer must capture traffic from server-facing interfaces on a Nexus 9000 leaf switch and deliver it to a packet analyzer located in a different data center pod across a routed Layer 3 boundary. The analyzer cannot be relocated, and no Layer 2 adjacency exists between the leaf and the analyzer subnet. Which monitoring method should the engineer implement to meet this requirement?

Accepted Answer

Configure an ERSPAN session that encapsulates the mirrored traffic in GRE and routes it to the remote analyzer's IP address

Answer

Configure a local SPAN session with the source interfaces and the destination pointing to a local physical port

Answer

Enable NetFlow export on the server-facing interfaces and send flow records to the analyzer via UDP

Answer

Configure an RSPAN session using a dedicated RSPAN VLAN trunked toward the remote pod
