Information About ERSPAN
The Cisco NX-OS system supports the Encapsulated Remote Switching Port Analyzer (ERSPAN) feature on
both source and destination ports. ERSPAN transports mirrored traffic over an IP 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 consists of an ERSPAN source session, routable ERSPAN generic routing encapsulation
(GRE)-encapsulated traffic, and an ERSPAN destination session. You can separately configure ERSPAN
source sessions and destination sessions on different switches.
ERSPAN Source Sessions
An ERSPAN source session is defined by the following:
•
A session ID.
•
A list of source ports, source VLANs, or source VSANs to be monitored by the session.
