MLD snooping configuration
Displaying software resource usage for VLANs
To display information about the software resources used, enter the show ipv6 mld-snooping
resource command.
Syntax: show ipv6 mld-snooping resource
The following table describes the output from the show ipv6 mld-snooping resource command.
uptime The up time of this mcache in minutes.
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.
Field Description
alloc The allocated number of units.
in-use The number of units which are currently used.
avail The number of available units.
get-fail Displays 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-max-group-addr command. The snoop mcache entry limit is configured using the
system-max mld-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.
NOTE: This number can be increased. More memory can be allocated if necessary.
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.
