6.4 Static Multicast Group Template
Use the static multicast filter to allow incoming frames based on multicast MAC address(es)
that you specify. This feature can be used in conjunction with IGMP snooping to allow
multicast MAC address(es) that are not learned by IGMP snooping. Use the static multicast
filter to pass routing protocols, such as RIP and OSPF.
A static multicast group template allows you to configure multicast filters efficiently. The
template can then be uploaded to one or more devices thus removing the need to configure the
static multicast filter settings for each device.
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1
recipient) or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets
to just a group of hosts on the network.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish
membership in a multicast group - it is not used to carry user data. Refer to RFC 1112 and RFC
2236 for information on IGMP versions 1 and 2 respectively.
You can set the switch to forward multicast data to specific port(s). This is essential for
sending multicast traffic to hosts that cannot report their membership with IGMP.

New/Add Click New/Add to create a new IGMP filter template.
Delete Click Delete to remove the selected IGMP filter template.
Modify Click Modify to change the settings of the selected IGMP filter template.
Start Address Enter the starting multicast IP address for a range of multicast IP addresses to
which you want this IGMP filter profile to allow access.
End Address Enter the ending multicast IP address for a range of IP addresses to which you
want this IGMP filter profile to allow access.
If you want to add a single multicast IP address, enter it in both the Start IP and
End IP fields.
Index This is the number of the IGMP filter profile. Double-click a profile’s index number
to edit the profile.
Start Address This field displays the starting multicast IP address for a range of multicast IP
addresses to which you want this IGMP filter profile to allow access.
End Address This field displays the ending multicast IP address for a range of IP addresses to
