About ERSPAN

ERSPAN transports mirrored traffic over an IP network, which provides remote monitoring of multiple
switches across your network. The traffic is encapsulated at the source router and is transferred across the
network. The packet is decapsulated at the destination router and then sent to the destination interface.

ERSPAN Types

Cisco Nexus 9300 Series switches support ERSPAN Type II, and Cisco Nexus 9500 Series switches support
only ERSPAN.
