CHAPTER 4
WEB OPERATION & CONFIGURATION
to ensure that multicast traffic is passed to all appropriate interfaces within the switch.
Fast Leave:
Enable fast leave function if the checkbox is ticked. When a leave packet is received, the switch
immediately removes it from a multicast service without sending a MLD group-specific (GS) query to that interface.
Throttling:
This field limits the maximum number of multicast groups that a port can join at the same time. When the
maximum number is reached on a port, any new MLD join reports will be dropped. By default, unlimited is selected.
Other allowed options are 1 – 10.
4.3.11.2.2 VLAN Configuration
This page is used to configure MLD Snooping for an interface.
VLAN ID:
Specify VLAN ID for MLD snooping.
Snooping Enabled:
Select the checkbox to enable snooping feature on an interface basis. When enabled, the switch
will monitor network traffic on the specified interface to determine which hosts want to receive multicast services.
Querier Election:
Enable to join querier election in the VLAN. When enabled, the switch can serve as the MLDv2
querier in the bidding process with other competing multicast routers or switches. Once it becomes querier, it will be
responsible for asking hosts periodically if they want to receive multicast traffic. When disabled, it will act as an IGMP
non-querier.
Compatibility:
This configures how hosts and routers take actions within a network depending on MLD version
selected. Available options are “MLD-Auto”, “Forced MLDv1”and “Forced MLDv2”. By default, MLD-Auto is used.
PRI:
Select the priority of interface. This field indicates the MLD control frame priority level generated by the system
which is used to prioritize different classes of traffic. The allowed range is 0 (best effort) to 7 (highest). By default,
interface priority value is set to 0.
RV:
The robustness variable (RV) allows tuning for the expected packet loss on a subnet. If a subnet is susceptible to
packet loss, this value can be increased. The RV value must not be zero and should not be one. The value should be 2
or greater. By default, it is set to 2. The allowed range is 1 -255.
QI (sec):
The Query Interval is the interval between IGMP General Query messages sent by the Querier. The default
Querier Interval is 125 seconds. The allowed interval range is 1 – 255 seconds.
QRI:
The Query Response Interval is the maximum amount of time that the IGMP router waits to receive a response to
a General Query message. The QRI applies when the switch is acting as the querier and is used to inform other devices
of the maximum time this system waits for a response to general queries. By default, RQI is set to 10 seconds. The
allowed range is 10 – 31744 tenths of a second.
LLQI:
The Last Listener Query Interval sets the interval that waits for a response to a group-specific or group-and-
source specific query message.
