CONFIGURING REMOTE PORT MIRRORING
Use the Mirroring & RSPAN Configuration page to mirror traffic from remote
switches for analysis at a destination port on the local switch. This feature,
also called Remote Switched Port Analyzer (RSPAN), carries traffic
generated on the specified source ports over a user-specified VLAN
dedicated to that RSPAN session in all participating switches. Monitored
traffic from one or more sources is copied onto the RSPAN VLAN through
IEEE 802.1Q trunk or hybrid ports that carry it to any RSPAN destination
port monitoring the RSPAN VLAN as shown in the figure below.
