Displaying IGMP snooping information
22
Syntax: show ip multicast mcache
The following table describes the output of the show ip multicast mcache command.
Displaying PIM sparse snooping information
PIM sparse mode snooping allows a device to listen for join or prune messages exchanged between
PIM routers, which helps reduce unwanted traffic. To display PIM snooping information, enter the
following command.
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 following command.
Field Description
(source group) Source and group addresses of this data stream. (* group) means match group only; (source
group) means match both.
cnt The number of packets processed in software. Packets are switched in hardware, which
increases this number slowly.
OIF The output interfaces. If entire vlan is displayed, this indicates that static groups apply to
the entire VLAN.
age The mcache age. The mcache will be reset to 0 if traffic continues to arrive, otherwise the
mcache will be aged out when it reaches the time defined by the ip multicast mcache-age
command.
uptime The up time of this mcache in minutes.
vidx Vidx specifies output port list index. Range is from 4096 to 8191
ref-cnt The vidx is shared among mcaches having the same output interfaces. Ref-cnt indicates the
number of mcaches using this vidx.
