Configuring IGMP interface static members

Configure IGMP interface static members to add members to a snoop group.

About this task

You can create a static entry to forward multicast data streams to a particular set of ports within the VLAN. After you create the entry, multicast data streams always forward to the multicast router within the VLAN, in addition to the ports in this static entry.

Important

Important

IGMP snoop can optimize only local multicast data flow. IGMP snoop does not manage the forwarding state of the multicast tree. You cannot configure a port as a static receiver in an IGMP snoop-enabled VLAN that does not contain at least one dynamic receiver port and forward multicast data.

You can configure IGMP on a VRF instance the same way you configure the Global Router except that you must first launch the appropriate VRF context.

Procedure

  1. In the navigation pane, expand the following folders: Configuration > IP.
  2. Click IGMP.
  3. Click the Static tab.
  4. Click Insert.
  5. Type the appropriate information.
  6. Click Insert.

Static field descriptions

Use the data in the following table to use the Static tab.

Name

Description

IfIndex

Shows the interface where the IGMP entry is enabled.

GrpAddr

Indicates the start of the IP multicast address range of the multicast stream.

Within the indicated valid range (224.0.0.0 to 239.255.255.255), the following are invalid addresses: 244.0.0.x and the corresponding 31 multicast addresses that map to the IP MAC addresses. If you try to select them, you receive an invalid message.

ToGrpAddr

Indicates the end of the IP multicast address range of the multicast stream. If an address is not entered, the IP address in the GrpAddr field is the single address.

MemberPorts

Specifies the ports to which you want to redirect the multicast stream for this multicast group. The ports must be member ports of the VLAN.

NotAllowedToJoin

Specifies the ports that do not receive the multicast stream for this multicast group.
