Field Description
(abcd:ef50 0:100): The lowest 32 bits of source and group. It is displayed in XXXX:XXXX hex format. Here
XXXX is a 16-bit hex number.
cnt The number of packets processed in software.
OIF Output interfaces.
age The mcache age in seconds. The mcache is reset to 0 if traffic continues to arrive, otherwise
it is aged out when it reaches the time defined by
ipv6 multicast mcache-age .
uptime The up time of this mcache in seconds.
vidx The vidx is shared among mcaches using the same output interfaces. The vidx specifies the
output port list, which shows the index. Valid range is from 4096 to 8191.
ref-cnt The number of mcaches using this vidx.
To display information about the software resources used, enter the following command.
