Configuring Broadband Settings
When information is broadcast on a network, information packets are delivered to all segments on
the LAN. This degrades network performance. IP multicasting is a method of forwarding information
to a group of interested receivers.
Internet Group Management Protocol (IGMP) is used to manage IP Multicast sessions. IGMP
provides a means to automatically control and limit the flow of multicast traffic throughout your
network with the use of special multicast queriers and hosts.
Steps
1.
Navigate to
Settings
>
Broadband
>
Multicast
. The
Multicast
page appears.
2.
Select the
IGMP Proxy
check box to enable the
feature. When IGMP Proxy is enabled, the
gateway issues IGMP host messages on behalf of the hosts discovered through standard
IGMP interfaces. In other words, the gateway acts as a proxy for its hosts.
3.
Select the
IGMP Snooping
check box to enable the feature. When IGMP Snooping is
enabled, the gateway analyzes all IGMP packets and selectively forwards multicast traffic
only to those ports where particular IP Multicast streams are accepted.
4.
Select the
IGMP Query Response Interval
check box to enable the feature. When IGMP
Query Response Interval is enabled, you control the number of IGMP messages allowed on
the subnet during the specified duration.
5.

IGMP Robustness
Time interval that the gateway waits for a report in response to a group-
specific query.
IGMP Query Interval
Time interval at which the gateway sends membership queries when it is the
querier.
IGMP Query Response Interval
Time interval that the gateway waits for a report in response to a general
query.
IGMP Group Membership Interval
Timeout period for group membership. If no report is received for these
groups before the timeout expires, the group membership is removed.
IGMP Startup Query Interval
Amount of time in seconds between successive General Query messages
sent by a querier during startup.
IGMP Startup Query Count
Number of general query messages sent at startup.
IGMP Last Member Query Interval
Time interval that the gateway waits for a report in response to a group-
specific query.
IGMP Last Member Query Count
Number of Group-Specific Query messages sent before the gateway assumes
that there are no members of the host group being queried on this interface.
IGMP Maximum Host Groups
Maximum number of host group members.
IGMP Maximum Sources
Maximum number of source-specific join and leave messages.
IGMP Query Count

memory allocation failure, IP address allocation failure, and so on.
IGMP Host Group Exceeded
Number of times host groups have exceeded in the message.
IGMP Sources Exceeded
Number of times source addresses have exceeded in the message.
IGMP Other Querier
Timeout period for group membership. If no report is received for these
groups before the timeout expires, the group membership is removed.

Resolving Domain Name
Objective
To manually add a domain name for resolving the IP address of the networked devices.
This task allows you to name network devices (such as printers or Web servers), so that they can
be easily accessed by other users on the network.
Note
Confirm that the domain name is not in use.
