Similarly one may ask, what is Span and Rspan?
The main difference between SPAN and RSPAN are the relationships between placement of the SPAN Source ports, and the SPAN Destination port to which your network monitoring device (IDS, IPS, Wireshark Laptop, etc) is connected. Whereas RSPAN allows you to decouple the SPAN Destination from the SPAN Source ports
Also, why is span necessary on today's switches? SPAN enables port mirroring or copying of traffic from a physical port on a switch to another port on that same switch to non-intrusively feed traffic to out-of-band security tools such as probes, intrusion detection systems, network recorders and network analyzers.
Moreover, what is a SPAN port?
SPAN [Switch Port Analyzer] Port Mirroring also known as SPAN (Switched Port Analyzer), sends a copy of all network packets seen on one port (or an entire VLAN) to another port, where the packets can be analyzed.
What is remote SPAN VLAN?
Remote SPAN RSPAN supports source ports, source VLANs, and destination ports on different switches (or different switch stacks), enabling remote monitoring of multiple switches across your network. Each RSPAN source switch must have either ports or VLANs as RSPAN sources.
