Is Rspan proprietary?
SPAN (Switched Port Analyzer) is a Cisco Proprietary feature which allows to send a copy of traffic passing through ports to another port on the switch.As demand on deep packet inspection and analysis grew , so did the development on SPAN and Cisco cam up with RSPAN and ERSPAN.
What is the difference between Span and Rspan?
When you use a destination interface on the same switch as your switch we call it SPAN, when the destination is a remote interface on another switch we call it RSPAN (Remote SPAN). When using RSPAN you need to use a VLAN for your RSPAN traffic so that traffic can travel from the source switch to the destination switch.
What is Cisco SPAN port?
The Switched Port Analyzer (SPAN) feature, sometimes called port mirroring or port monitoring, allows you to take a copy of network traffic as it passes through a network switch. You use it to send a copy of network packets seen on one switch port (or an entire VLAN) to another switch port.
How do you set up a Rspan?
Configuring RSPAN
- On the source device, enter the configure terminal command to access global configuration mode.
- Enter the rspan-vlan command, specifying a VLAN ID, to define an RSPAN VLAN on the source device.
- Enter the tagged ethernet command, specifying an interface, to add a member port.
What is IP SLA in networking?

What is a Erspan?
ERSPAN is an acronym that stands for encapsulated remote switched port analyzer. ERSPAN mirrors traffic on one or more “source” ports and delivers the mirrored traffic to one or more “destination” ports on another switch.
What is SPAN port?
