This feature is in contrast to Remote SPAN (RSPAN), which this list also defines. Remote SPAN (RSPAN)-Some source ports are not located on the same switch as the destination port. RSPAN is an advanced feature that requires a special VLAN to carry the traffic that is monitored by SPAN between switches. RSPAN is not supported on all switches. Check the respective release notes or configuration guide to see if you can use RSPAN on the switch that you deploy. Port-based SPAN (PSPAN)-The user specifies one or several source ports on the switch and one destination port. VLAN-based SPAN (VSPAN)-On a particular switch, the user can choose to monitor all the ports that belong to a particular VLAN in a single command. Local SPAN Overview A local SPAN session is an association of source ports and source VLANs with one or more destinations. You configure a local SPAN session on a single switch. Local SPAN does not have separate source and destination sessions. Local SPAN sessions do not copy locally sourced RSPAN VLAN traffic from source trunk ports that carry RSPAN VLANs. Local SPAN sessions do not copy locally sourced RSPAN GRE-encapsulated traffic from source ports. Each local SPAN session can have either ports or VLANs as sources, but not both. You can analyze network traffic passing through ports or VLANs by using SPAN or RSPAN to send a copy of the traffic to another port on the switch or on another switch that has been connected to a network analyzer or other monitoring or security device. SPAN copies (or mirrors) traffic received or sent (or both) on source ports or source VLANs to a destination port for analysis. SPAN does not affect the switching of network traffic on the source ports or VLANs. You must dedicate the destination port for SPAN use. Except for traffic that is required for the SPAN or RSPAN session, destination ports do not receive or forward traffic. Only traffic that enters or leaves source ports or traffic that enters or leaves source VLANs can be monitored by using SPAN; traffic routed to a source VLAN cannot be monitored. For example, if incoming traffic is being monitored, traffic that gets routed from another VLAN to the source VLAN cannot be monitored; however, traffic th ... https://www.youtube.com/watch?v=9uFZ8arTYGE

Learn Pica8 white box switching - OpenFlow, OpenDaylight, BGP and more: http://academy.gns3.com/courses/pica8-white-box-switching-fundamentals This course explains and demonstrates white box switching technology using Pica8's operating system and physical white box switches. Modules included: Overview of Pica8 architecture Configure BGP on Pica8 switches Configure OpenFlow without a controller (add flows manually to Open vSwitch) Integrate Pica8 switches with multiple controllers: OpenDaylight Floodlight HP VAN Learn how to configure Pica8 PicOS in both Layer2/Layer3 mode and OpenFlow mode: PicOS is the Pica8 network operating system software used on white box switches. PicOS eliminates vendor lock-in by delivering open, hardware-agnostic networking. Built on Linux, PicOS incorporates a full Layer-2 and Layer-3 feature set with support for OpenFlow, OVSDB, and other key SDN protocols. PicOS enables customers to deliver differentiated network applications and services on white box switches. PicOS features vASIC®, a hardware abstraction technology that simplifies the process of supporting new hardware platforms, and it’s built on an unmodified Debian Linux kernel, making it easy for users to develop and integrate network applications. Learn how to configure Open vSwitch on Pica8 switches: Open vSwitch (OVS) is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It’s designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, SPAN, RSPAN, CLI, LACP and 802.1ag). Available on all Pica8® and supported white box switches, PicOS™ supports OpenFlow 1.4 through OVS 2.3 integration. OVS runs as a process within PicOS™, providing the OpenFlow and OVSDB interfaces for external programmability by controllers or orchestration platforms. ... https://www.youtube.com/watch?v=2bOX1jlpV8k
