FieldDescription

(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.
