IGMP snooping show commands
Displaying software resource usage for VLANs
To display information about the software resources used, enter the following command.
Syntax: show ip multicast resource
The following table describes the output from the show ip multicast resource command.
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 seconds.
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.
Table 0.7:
This field... Displays...
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 may 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.
