IPv6 Multicast Traffic Reduction

(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.

The following table describes the output from the show ipv6 multicast resource command.

Field	Displays

alloc	The allocated number of units.

in-use	The number of units which are currently used.

avail	The number of available units.

get-fail	The number of resource failures

	NOTE
	It is important to pay close attention to this field.


limit	The upper limit of this expandable field. The MLD group limit is configured using the system-
	max mld-snoop-group-addrcommand. The snoop mcache entry limit is configured using the
	system-max mld-snoop-mcache command.
