The character 'R' is short for 'Remote' which means that the mirror source ports and the destination port are not within the same Switch. So a remote mirror session consists of at least two switches. To achieve the remote mirroring function, the mirrored traffic are tagged with a reserved VLAN which is called RSPAN VLAN, The RSPAN VLAN is reserved in such a way that traffic tagged with RSPAN tagged will be mirrored toward the associated destination port. The following figure illustrates the remote mirroring via RSPAN VLAN. DGS-6600 Configuration Guide 590
