Software User Manual 12/10/09 D-Link Unified Access System CONFIGURING IGMP SNOOPING QUERIERS IGMP snooping requires that one central switch or router periodically query all end-devices on the network to announce their multicast memberships. This central device is the 'IGMP querier'. The IGMP query responses, known as IGMP reports, keep the switch updated with the current multicast group membership on a port-by-port basis. If the switch does not receive updated membership information in a timely fashion, it will stop forwarding multicast to the port where the end device is located. These pages enable you to configure and display information on IGMP snooping queriers on the network and, separately, on VLANs. IGMP SNOOPING QUERIER CONFIGURATION Use this page to enable or disable the IGMP Snooping Querier feature, specify the IP address of the router to perform the querying, and configure related parameters. Users must have Read/Write access privileges to change the data on this page. To access this page, click LAN > L2 Features > IGMP Snooping Querier > Querier Configuration in the navigation tree. Figure 144: IGMP Snooping Querier Configuration Table 127: IGMP Snooping Querier Configuration Fields Field Snooping Querier Admin Mode Snooping Querier Address IGMP Version Query Interval Querier Expiry Interval Description Select the administrative mode for IGMP Snooping for the switch from the pulldown menu. The default is Disable. Specify the Snooping Querier Address to be used as source IP address in periodic IGMP queries. This address is used when no address is configured on the VLAN on which query is being sent. Specify the IGMP protocol version used in periodic IGMP queries. Specify the time interval in seconds between periodic queries sent by the snooping querier. The Query Interval must be a value in the range of 1 and 1800 seconds. The default value is 60 seconds. Specify the time interval in seconds after which the last querier information is removed. The Querier Expiry Interval must be a value in the range of 60 and 300. The default value is 60 seconds.

IGMP snooping requires that one central switch or router periodically query all end-devices on the network to announce their
multicast memberships. This central device is the 'IGMP querier'. The IGMP query responses, known as IGMP reports, keep
the switch updated with the current multicast group membership on a port-by-port basis. If the switch does not receive
updated membership information in a timely fashion, it will stop forwarding multicast to the port where the end device is
located.
These pages enable you to configure and display information on IGMP snooping queriers on the network and, separately,
on VLANs.

Field
Description
Snooping Querier Admin
Mode
Select the administrative mode for IGMP Snooping for the switch from the pulldown
menu. The default is
Disable
.
Snooping Querier Address
Specify the Snooping Querier Address to be used as source IP address in periodic
IGMP queries. This address is used when no address is configured on the VLAN on
which query is being sent.
IGMP Version
Specify the IGMP protocol version used in periodic IGMP queries.
Query Interval
Specify the time interval in seconds between periodic queries sent by the snooping
querier. The Query Interval must be a value in the range of 1 and 1800 seconds. The
default value is 60 seconds.
Querier Expiry Interval
Specify the time interval in seconds after which the last querier information is removed.
The Querier Expiry Interval must be a value in the range of 60 and 300. The default
value is 60 seconds.
