Configuring IP Multicast 667
The MLD Routing Interface Summary page contains the following fields:
•
Interface
— Select the VLAN for which data is to be displayed.
Interface Parameters section:
•
Global Admin Mode
— Displays whether MLD has been globally enabled or disabled.
•
Interface Mode
— Displays whether the administrative status of MLD on the selected interface is
enabled or disabled.
•
Operational Mode
— Displays the operational state of MLD on the selected interface, regardless of
the administrative setting.
•
Version
— Displays the version of MLD configured on the selected interface.
•
Query Interval
— Displays the interval in seconds at which MLD host-query packets are transmitted
on the selected interface.
•
Query Max Response Time
— Displays the maximum query response time in milliseconds (ms)
advertised in MLDv2 queries from the selected interface.
•
Robustness
— Displays the robustness parameter for the selected interface. This value allows tuning
for the expected packet loss on a subnet. If a subnet is expected to be lossy, increase the robustness
variable. MLD is robust to (robustness variable - 1) packet losses.
•
Startup Query Interval
— Displays the interval in seconds at which startup queries are sent on the
selected interface.
•
Startup Query Count
— Displays the number of queries to be sent upon startup.
•
Last Member Query Interval
— Displays the maximum response time, in milliseconds, inserted into
group-specific queries sent in response to leave group messages. This value is also the amount of time
between group-specific query messages. This value may be tuned to modify the leave latency of the
network. This value may be tuned to modify the leave latency of the network. A reduced value results
in reduced time to detect the loss of the last member of a group.
NOTE: This value is not used for MLD version 1.
•
Last Member Query Count
— The number of queries to be sent on receiving a leave group report.
Interface Statistics section:
•
Querier Status
— Displays whether the selected router interface is currently the MLD querier. If
another interface on the network has a lower source IP address, it becomes the querier.
•
Querier
— The address of the MLD querier on the IP subnet to which the selected interface is
attached.
•
Querier Up Time
— The time in hours:minutes:seconds since the MLD interface querier was last
changed.
•
Querier Expiry Time
— The time in hours:minutes:seconds remaining before the other querier
present timer expires. If the local system is the querier, this will be zero.
