The fast-switched packet count represents the number of packets that were switched in hardware on the
corresponding route.
The partially switched packet counter represents the number of times that a fast-switched packet was
also copied to the CPU for software processing or for forwarding to one or more non-platform switched
interfaces (such as a PimTunnel interface).
The slow-switched packet count represents the number of packets that were switched completely in
software on the corresponding route.

(1.2.3.4, 225.6.7.8, Vlan3) 00:01:50
The full (S,G) flow and the ingress interface on which incoming packets are dropped is shown. The
timestamp indicates the age of the entry.
