Description
Information about IP multicast sources:
Entries preceded by angle brackets (>) are
subnetworks that contain sources.
Entries without angle brackets are the IP addresses of
source devices.
IP multicast group address of packets coming from the
source and subnetwork to the left.
Time since the cache entry was originally recorded. Time is
noted in hours (h), minutes (m), and seconds (s).
Value that indicates the remaining life for the cache entry.
Time is recorded in minutes (m) and seconds (s). The
system assigns a life of approximately 7 minutes to each
entry. When the age if the entry decreases to zero, the
entry either disappears or is refreshed.
Time remaining before the system sends a prune message
to an upstream router. Time is shown in minutes (m) and
seconds (s). When traffic is actively flowing, a dash (-)
indicates that no prune message has been sent upstream.
