Figure 3 - 38 MLD Snooping Settings – Edit window
The following parameters may be viewed or modified:
Parameter Description
VLAN ID
This is the VLAN ID that, along with the VLAN Name, identifies the VLAN for which
to modify the MLD Snooping Settings.
VLAN Name
This is the VLAN Name that, along with the VLAN ID, identifies the VLAN for which
to modify the MLD Snooping Settings.
Query Interval
The Query Interval field is used to set the time (in seconds) between transmitting
MLD queries. Entries between 1 and 65535 seconds are allowed. Default = 125.
Max Response Time
This determines the maximum amount of time in seconds allowed to wait for a
response for MLD port listeners. The Max Response Time field allows an entry
between 1 and 25 (seconds). Default = 10.
Robustness Variable
Provides fine-tuning to allow for expected packet loss on a subnet. The user may
choose a value between 1 and 255 with a default setting of 2. If the packet loss rate
in a subnet is expected to be high, the user may wish to increase this interval.
Last Listener Query Interval
The maximum amount of time to be set between group-specific query messages.
This interval may be reduced to lower the amount of time it takes a router to detect
the loss of a last listener group. The user may set this interval between 1 and 25
seconds with a default setting of 1 second.
Version (1-2)
Configure the MLD version of the query packet which will be sent by the router.
Node Timeout
Specifies the link node timeout, in seconds. After this timer expires, this node will no
longer be considered as listening node. Default setting is 260 seconds.
