Last listener query count
- Number of group-specific queries sent before the
router assumes there are no local listeners of a group. The default number is
the value of the robustness variable.
•
By default, the robustness variable is set to 2. You might want to increase this
value if you expect a subnet to be loosely.
Last Listener Query
Interval (1-25)
The maximum amount of time between group-specific query messages, including those
sent in response to done-group messages. You might lower this interval to reduce the
amount of time it takes a router to detect the loss of the last listener of a group. This
interval is calculated as follows: (last listener query interval * robustness variable).
Data Driven Group
Expiry Time (1-65535)
Here the user can enter the data driven group expiry time value.
Querier State
This allows the switch to be specified as an MLD Querier (sends MLD query packets) or
a Non-Querier (does not send MLD query packets). Set to enable or disable.
Fast Done
Here the user can enable or disable the fast done feature.
State
Used to enable or disable MLD snooping for the specified VLAN. This field is
Disabled
by default.
Report Suppression
Here the user can enable or disable the report suppression features. This feature
prevents duplicate reports from being sent to the multicast devices. If you disable MLD
report suppression, all MLD reports are forwarded to the multicast routers.
Data Driven Learning
State
Enable or disable data driven learning of MLD snooping groups.
Data Driven Learning
Aged Out
Enable or disable the age out function for data driven entries.
Version
Specifies the version of MLD packet that will be sent by this port. If a MLD packet
received by the interface has a version higher than the specified version, this packet will
be forwarded from the router ports or VLAN flooding.
