ERSPAN on Nexus 5x00<br />

The Nexus 5x00 series switches have the capability to configure traditional SPAN sessions,<br />

referred to as local SPAN sessions, for Ethernet traffic in addition to ERSPAN. ERSPAN<br />

differs from traditional SPAN in that ERSPAN enables the monitored traffic to be<br />

encapsulated in a GRE packet <strong>and</strong> routed acr<strong>os</strong>s an IP network. With ERSPAN, network<br />

administrators can centralize network analysis tools <strong>and</strong> route the monitored traffic.<br />

ERSPAN builds on the concepts of source ports <strong>and</strong> destination ports. Source ports, as their<br />

name implies, are the source of the traffic to be sent via ERSPAN to the destination ports.<br />

Source ports have the following requirements:<br />

• Can be any port type including Ethernet, virtual Ethernet, port channel, VLAN, or<br />

VSAN.
