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
~
31744 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 0
~
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.
URI:
The Unsolicited Report Interval is the amount of time that the upstream interface should transmit unsolicited
IGMP reports when report suppression/proxy reporting is enabled. By default, URI is set to 1 second. The allowed
range for URI is 0
~
31744 seconds.

3.11.2.3 Port Filtering Profile
The Port Filtering Configuration page is to filter specific multicast traffic on a per port basis. Before you select a
filtering profile for filtering purposes, you must set up profiles in IPMC Profile page.
Port:
List the number of each port.
Filtering Profile:
Select the configured multicast groups that are denied on a port. When a certain multicast group is
selected on a port, MLD join reports received on a port are dropped.
