Configuring IGMP Snooping and MVR
How to Configure IGMP Snooping and MVR
Disabling IGMP Report Suppression
Before You Begin
IGMP report suppression is supported only when the multicast query has IGMPv1 and IGMPv2 reports. This feature is not
supported when the query includes IGMPv3 reports.
Configuring MVR
Configuring MVR Global Parameters
You do not need to set the optional MVR parameters if you choose to use the default settings. If you do want to change
the default parameters (except for the MVR VLAN), you must first enable MVR.

(Optional) Sets the length of time until the IGMP querier expires. The
range is 60 to 300 seconds.
7. ip igmp snooping querier version version (Optional) Selects the IGMP version number that the querier feature
uses. Select 1 or 2.

3. mvr group ip-address [count] Configures an IP multicast address on the switch or use the count parameter
to configure a contiguous series of MVR group addresses (the range for count
is 1 to 256; the default is 1). Any multicast data sent to this address is sent to
all source ports on the switch and all receiver ports that have elected to
receive data on that multicast address. Each multicast address would
correspond to one television channel.
4. mvr querytime value (Optional) Defines the maximum time to wait for IGMP report memberships
on a receiver port before removing the port from multicast group
membership. The value is in units of tenths of a second. The range is 1 to 100,
and the default is 5 tenths or one-half second.
