To view and configure IGMP Snoop Querier Configuration details:
1. Select Network > IGMP Snooping from the main menu tree.
2. Select the IGMP Snoop Querier Config tab
The IGMP Snoop Querier Config tab displays the following information:
Max Response Time Specifies the maximum allowed time before sending a responding report. When no
reports are received from a portal, that portal information is removed from the
Snooping Table. The switch will only forward Multicast Packets to portals that are
present in the Snooping Table. For IGMP reports from wired ports, the switch
forwards these reports to the Multicast Router Ports.
Version Sets the IGMP version compatibility. Select from IGMP v1, v2, or v3.
IP Address This address is applied as the source address in the IGMP Query packet. This value
is used as the default VLAN Querier IP address.
Present Timeout This is the time duration after which the switch's IGMP Querier is activated. A
Querier is used to accommodate any query loss due to a Multicast Router being
down or not accessible. It is also used to accommodate any local network query
loss. The Querier generates IGMP queries on receipt of which the interested hosts
reply with an IGMP report. On receipt of an IGMP report, the Snooping Table on the
switch is updated with the host's portal information. Any IGMP packet from the
Multicast Server is then forwarded to the particular portal.
Interval This is the common interval in seconds between two IGMP Queries generated by
the IGMP Querier. This is valid for all VLANs.
VLAN Index The index of the selected VLAN.
Enable The enable state of IGMP Snoop Querier on this VLAN.
Version The IGMP version in use.
Present Timeout The time duration in seconds after which the switch's querier takes over the role of
IGMP querier for this VLAN.
