RSPAN Settings

This window controls the RSPAN function. The purpose of the RSPAN function is to mirror packets to a remote
switch. A packet travels from the switch where the monitored packet is received, passing through the intermediate
switch, and then to the switch where the sniffer is attached. The first switch is also named the source switch.
To make the RSPAN function work, the RSPAN VLAN source setting must be configured on the source switch. For
the intermediate and the last switch, the RSPAN VLAN redirect setting must be configured.
NOTE: RSPAN VLAN mirroring will only work when RSPAN is enabled (when one RSPAN VLAN has
been configured with a source port). The RSPAN redirect function will work when RSPAN is
enabled and at least one RSPAN VLAN has been configured with redirect ports.
