IGMP Proxy

This section describes Internet Group Management Protocol (IGMP) Proxy configuration.

Note:

This web page is visible in WEBUI, but is not supported for this release.

IGMP Proxy enables the system to issue IGMP host messages on behalf of the discovered hosts. IGMP proxy provides queue interface and socket interface options to receive and transmit the IGMP control packets and multicast data packets.

IGMP proxy device performs router portion of IGMP on the downstream interfaces and host portion of IGMP on the upstream interfaces. IGMP proxy device consolidates the reports received in the downstream interfaces, and sends a summarized report on to the upstream interface.

To access IGMP Proxy screens, go to Multicast > IGMP Proxy.

IGMP Proxy Configuration

By default, the tab Basic Settings displays the IGMP Proxy Configuration screen.

Figure 1. IGMP Proxy Configuration

Screen Objective	This screen allows the user to configure the IGMP Status.
Navigation	Multicast > IGMP Proxy > Basic Settings
Fields	Proxy Status—enables/ Disables IGMP Proxy in the Switch. The default option is Disabled. The list contains: Enabled—starts IGMP proxy module. Disabled—stops IGMP proxy module. Note: IGMP proxy can be enabled only when the multicast routing protocol PIM is disabled.
Buttons	Apply—modifies attributes and saves the changes. Reset—resets to default value for respective fields and discards all user input.

IGMP Upstream Interface Configuration

Figure 2. IGMP Upstream Interface Configuration

Screen Objective	This screen allows the user to configure the IGMP Proxy Upstream Interfaces.
Navigation	Multicast > IGMP Proxy > Upstream Interface
Fields	Interface—specifies the Layer 3 VLAN Interface, which is defined as an upstream interface. Interface Index—specifies the index value of the Layer 3 VLAN Interface, which is defined as an upstream interface. This is a read-only field. This value ranges from 1 to 65535. Configured Version—specifies the configured version of the IGMP Proxy device on the upstream interface. The options are Version 1, Version 2, and Version 3. Default is Version 3. Version Purge Interval—specifies the interval (in seconds) after which the upstream interface IGMP operating version will be changed to configured IGMP version. This value ranges from 60 to 600 seconds. Operating Version—indicates the operating version of the IGMP Proxy device on the upstream interface. This is a read-only field. The options are Version 1, Version 2, and Version 3.
Buttons	Add—adds and saves new configuration. Reset—resets to default value for respective fields and discards all user input. Apply—modifies attributes and saves the changes. Delete—deletes the selected entry.

IGMP Proxy MRoute Configuration

Figure 3. IGMP Proxy MRoute Configuration

Screen Objective	This screen allows the user to view the multicast routing information for the registered group members. MRoute stands for multicast static route.
Navigation	Multicast > IGMP Proxy > MRoute Information
Fields	Source—indicates the Unicast Source IP address of the data source that sends multicast datagrams for the registered multicast groups. Group—indicates the IP multicast group address for which multicast registrations are received. Upstream Interface Index—indicates the index value of the upstream interface on which IP multicast datagrams are received for the registered group address.

IGMP Proxy Next Hop Configuration

Figure 4. IGMP Proxy Next Hop Configuration

Screen Objective	This screen allows the user to view the list of outgoing interfaces for the multicast forwarding entries.
Navigation	Multicast > IGMP Proxy > Next Hop Information
Fields	Source—indicates the Unicast Source IP address of the data source that sends multicast datagrams for the registered multicast groups. Group Adress—indicates the IP multicast group address for which multicast registrations are received. Next Hop Upstream Interface Index—indicates the index value of the interface on which multicast registrations for the group are received. Next Hop Stateindicates the state of the outgoing interface on which the multicast registrations have been received. The options are: Forwarding—denotes that the entry is created. Prune— prune messages are used to prevent future messages from propagating to routers without group membership information (RFC 3973).
