through which mirrored traffic is passed on to
the RSPAN VLAN, the traffic type to monitor (Rx, Tx or Both) on the
source port(s), and the intermediate (or uplink) ports.
2. Set up all intermediate switches on the RSPAN configuration page,
specifying the switch type (Intermediate), the RSPAN VLAN, and the
intermediate ports.
3. Set up the destination switch on the Mirroring & RSPAN
configuration page by specifying switch type (Destination), the
RSPAN VLAN, intermediate ports, and the destination port(s) where
the mirrored traffic will be received.
