In other word, you can monitor another switch’s port or VLANrather than yours with RSPAN. This type of SPAN ( Switch Port Analyzer) is the SPAN in which source and destination ports are in different switches. Remote Switch Port Analyzer (RSPAN) is another SPANtype that is used to mirror source ports/vlans traffic to destination ports. Source Port and Destination VLAN Config (on source switch).SPAN is the problem that confuses many network administrators. With port mirroring enabled, the switch sends a copy of all network packets seen on one port (or an entire VLAN) to another port, where the packet can be analyzed. Right before TAP aggregation coming to our sight, SPAN (Switched Port Analyzer), also known as Port Mirroring, serves as the method of monitoring network traffic.

TAP aggregator thus provides total traffic visibility into network and facilitates optimal performance and security. It can be placed between any network devices, for example, between a 10Gb Ethernet switch and a router, or a Gigabit PoE switch and a client. TAP aggregation connects many network ports to one monitoring port (M:1), so that network traffic from multiple segments can be sent to a single network traffic analyzer. TAP aggregation copies data that flows from ports A to B and B to A and merge them together into one monitoring port, then it will send all the traffic out to the attached tool or monitoring device. TAP aggregation, or TAP aggregator, is an external, plug-and-play device installed directly to the network where it copies data continuously 24/7 without compromising network integrity. So we will focus on explaining TAP aggregation functions and benefits. Amidst the various types of network TAPs, the demand for TAP aggregation is flourishing and still on the rise. Network TAPs are niche products designing to keep your network running smoothly and secure. And implementing a network TAP is proven one of the best methods to get data from your network and into your monitoring & security tools – simply by creating permanent, in-line monitoring ports. Getting 100% traffic visibility of network is fundamental to business success.
