Description

This command enables IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. or IGMP snoopingIGMP snooping prevents multicast flooding on Layer 2 network by treating multicast traffic as broadcast traffic. Without IGMP snooping, all streams could be flooded to all ports on that VLAN. When multicast flooding occurs, end-hosts that happen to be in the same VLAN would receive all the streams only to be discarded without snooping. on this interface, or configures a VLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. interface for uninterrupted streaming of multicast traffic.

Parameter

Description

proxy

Enable IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. proxy for this interface.

gigabitethernet <slot/module/port>

Enable IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. proxy on the specified GigabitEthernet (IEEEInstitute of Electrical and Electronics Engineers. 802.3) interface.

port-channel <id>

Enable IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. proxy on the specified port channel.

snooping

Enable IGMP snoopingIGMP snooping prevents multicast flooding on Layer 2 network by treating multicast traffic as broadcast traffic. Without IGMP snooping, all streams could be flooded to all ports on that VLAN. When multicast flooding occurs, end-hosts that happen to be in the same VLAN would receive all the streams only to be discarded without snooping..

The IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. protocol enables an router to discover the presence of multicast listeners on directly-attached links. Enable IGMP snoopingIGMP snooping prevents multicast flooding on Layer 2 network by treating multicast traffic as broadcast traffic. Without IGMP snooping, all streams could be flooded to all ports on that VLAN. When multicast flooding occurs, end-hosts that happen to be in the same VLAN would receive all the streams only to be discarded without snooping. to limit the sending of multicast frames to only those nodes that need to receive them.

Usage Guidelines

The newer IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. proxy feature and the older IGMP snoopingIGMP snooping prevents multicast flooding on Layer 2 network by treating multicast traffic as broadcast traffic. Without IGMP snooping, all streams could be flooded to all ports on that VLAN. When multicast flooding occurs, end-hosts that happen to be in the same VLAN would receive all the streams only to be discarded without snooping. feature cannot be enabled at the same time, as both features add membership information to multicast group table. For most multicast deployments, you should enable the IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. Proxy feature on all VLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. interfaces to manage all the multicast membership requirements on the managed device. If IGMP snoopingIGMP snooping prevents multicast flooding on Layer 2 network by treating multicast traffic as broadcast traffic. Without IGMP snooping, all streams could be flooded to all ports on that VLAN. When multicast flooding occurs, end-hosts that happen to be in the same VLAN would receive all the streams only to be discarded without snooping. is configured on some of the interfaces, there is a greater chance that multicast information transfers may be interrupted.

This release of ArubaOS supports version 1 of the MLDMulticast Listener Discovery. A component of the IPv6 suite. It is used by IPv6 routers for discovering multicast listeners on a directly attached link. protocol (MLDv1). MLDv1, defined in RFCRequest For Comments. RFC is a commonly used format for the Internet standards documentss. 2710, is derived from version 2 of the IPv4 IGMPv2. You can use the command interface vlan <vlan> ipv6 mld to enable the MLDMulticast Listener Discovery. A component of the IPv6 suite. It is used by IPv6 routers for discovering multicast listeners on a directly attached link. protocol and allow an IPv6 router to discover the presence of multicast listeners on directly-attached links. Use the CLICommand-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. command interface vlan <vlan> ipv6 mld snooping for the Pv6 router to send multicast frames to only those nodes that need to receive them.
