Configuring RSPAN Configuration prerequisites
■ The source switch, intermediate switch, and the destination switch have been
determined.
■ The source port, the reflector port, the destination port, and the remote-probe
VLAN have been determined.
■ Required configurations are performed to ensure Layer 2 connectivity between
the source and destination switches over the remote-probe VLAN.
■ The direction of the packets to be monitored has been determined.
■ The remote-probe VLAN is enabled.
