Displaying IGMP snooping information
This output shows the number of OIF due to PIM out of the total OIF. The join or prune messages
are source-specific. In this case, if the mcache is in (* G), the display function will also print the
traffic source information.
Displaying software resource usage for VLANs
To display information about the software resources used, enter the show ip multicast resource
command.
Syntax: show ip multicast resource
The following table describes the output from the show ip multicast resource command.
Field Description
alloc The allocated number of units.
in-use The number of units which are currently being used.
avail The number of available units.
get-fail This displays the number of resource failures.
NOTE: It is important to pay attention to this field.
limit The upper limit of this expandable field. The limit of multicast group is configured by the
system-max igmp-max-group-addr command. The limit of snoop mcache entry is
configured by the system-max multicast-snoop-mcache command.
get-mem The number of memory allocation. This number should continue to increase.
size The size of a unit (in bytes).
init The initial allocated amount of memory. More memory can be allocated if resources run out.
Available vidx The output interface (OIF) port mask used by mcache. The entire device has a maximum of
4096 vidx. Different mcaches with the same OIF share the same vidx. If vidx is not available,
the stream cannot be hardware-switched.
