  Introduction:   Switch port Analyzer (SPAN) is an efficient, high performance traffic monitoring system. It duplicated network traffic to one or more monitor interfaces as it transverse the switch. SPAN is used for troubleshooting connectivity issues and calculating network utilization and performance, among many others. There are three types of SPANs supported on Cisco products, which are illustrated in below diagram.   Types of SPAN:         Local SPAN:  Mirrors traffic from one or more interface on the switch to one or more interfaces on the same switch.     Remote SPAN (RSPAN):  An extension of SPAN called remote SPAN or RSPAN. RSPAN allows you to monitor traffic from source ports distributed over multiple switches, which means that you can centralize your network capture devices. RSPAN works by mirroring the traffic from the source ports of an RSPAN session onto a VLAN that is dedicated for the RSPAN session. This VLAN is the...
