5.8.6.4.2 Displaying the Multicast Forwarding Cache
The switch maintains a cache of multicast routing entries used to calculate the delivery tree in multicast
routing protocols. The Multicast Forwarding Cache includes the subnetwork that contains the multicast
source and the nearest upstream neighbor for each known multicast group address.
Parameter Description
Group Address An IP multicast group address with subscribers directly attached or downstream
from this switch.
Source Address The IP subnetwork at the root of the multicast delivery tree. This subnetwork
contains a known multicast source.
Mask Subnet mask that is used for the source address. This mask identifies the host
address bits used for routing to specific subnets.
Upstream Neighbor The IP address of the network device immediately upstream for this group.
Protocol The multicast routing protocol associated with this entry.
Up Time The time elapsed since this entry was created.
