The value range is 1 to 100, and the default value is 50. The smaller the ratio is, the smaller the broadcast traffic is allowed to pass. bandwidth: Broadcast suppression bandwidth in Mbps on the port. The value ranges from 1 to the maximum value of port bandwidth. Use the broadcast-suppression command to set the broadcast suppression ratio or broadcast suppression bandwidth. Use the undo broadcast-suppression command to restore the default setting. The default broadcast suppression ratio is 50%. You can use the broadcast-suppression command repeatedly. The effective broadcast suppression ratio is the one last updated. 1-1

10 Command Manual Common Multicast Configuration Chapter 1 Common Multicast Configuration Caution: You cannot enable both broadcast suppression and multicast suppression simultaneously on the same card. Namely, once you have enabled broadcast suppression on some ports of a card, you cannot enable multicast suppression on the other ports of the card, and vice versa. If multicast suppression is enabled, broadcast packets are also suppressed at the same time, while broadcast suppression does not work on multicast suppression.

Namely, once you have enabled broadcast suppression on some ports of a card, you cannot enable multicast suppression on the other ports of the card, and vice versa. Although the commands are based on ports, the mutual exclusion between these two commands is based on cards. If multicast suppression is enabled, broadcast packets are also suppressed at the same time, while broadcast suppression does not work on multicast packets.

Use the igmp-snooping disable command to disable IGMP Snooping. By default, the switch disables IGMP Snooping. 1-5

29 Command Manual IGMP Snooping Configuration Chapter 1 IGMP Snooping Configuration Caution: When configuring IGMP Snooping, first enable global IGMP Snooping in system view, and then enable IGMP Snooping in VLAN view. Otherwise the IGMP Snooping function will not take effect. If the VLAN VPN is enabled on a port, the IGMP Snooping feature cannot be enabled on the VLAN for the port or the IGMP feature cannot be enabled on the corresponding VLAN interface. If IGMP Snooping feature is enabled in a VLAN, or IGMP is enabled on the VLAN interface, you cannot add the member port on which VLAN VPN is enabled into the VLAN. Isolate-user-VLAN supports the IGMP-Snooping function. After IGMP-Snooping is enabled under isolate-user-vlan, all secondary VLANs are IGMP-Snooping enabled. In a secondary VLAN, IGMP packets will be directly converted and processed in isolate-user-vlan, namely all the multicast services are implemented within isolate-user-vlan. Ports in secondary VLANs cannot be used as source addresses of multicast. If the undo igmp-snooping command is executed in system view, all IGMP Snooping configurations previously made are removed. # Enable IGMP Snooping in system view. System : return to User with Ctrl+Z.

Use the igmp-snooping 10ge-non-flooding enable slot command to suppress the ports on the specified interface board from flooding unknown multicast packets at Layer 2. Use the undo igmp-snooping 10ge-non-flooding enable slot command to remove the configuration. By default, a port floods unknown multicast traffic at Layer 2. Note: Currently, this command is not supported. # Suppress the interface board at Slot 5 from flooding unknown multicast traffic at Layer 2. System : return to User with Ctrl+Z.

The vlan-id argument ranges from 1 to

31 Command Manual IGMP Snooping Configuration Chapter 1 IGMP Snooping Configuration Use the igmp-snooping fast-leave command to enable IGMP Snooping fast leave. Use the undo igmp-snooping fast-leave command to disable IGMP Snooping fast leave. You can optionally specify multiple VLANs in the igmp-snooping fast-leave command, through which you can enable IGMP Snooping fast leave in the corresponding VLANs. If you do not specify any VLAN, IGMP Snooping fast leave is enabled in all VLANs. Note: Fast leaves that are configured in system view and Ethernet port view operate separately. Fast leave works on all ports of the specified VLANs if you configure it in system view. However, it only works on the current port (e.g., a port operates as a trunk of multiple VLANs) in the specified VLANs if you configure it in Ethernet port view. Caution: Fast leave configured for a port takes effect only when the VLAN it belongs to is IGMP Snooping-enabled. Fast leave does not work if the corresponding specified VLANs do not exist, the port does not belongs to any of the specified VLANs, or the VLANs do not have IGMP Snooping enabled. A newly configured IGMP Snooping clears all existing fast leave configurations. The igmp-snooping fast-leave command is useless if you do not enable IGMP Snooping globally. (You can enable IGMP Snooping globally by executing the igmp-snooping enable command in system view.) When you configure IGMP Snooping fast leave on aggregation ports, the configuration takes effect only on primary aggregation ports. If you add an IGMP V1 host of the same multicast group to the port, the switch does not remove the port when the port receives an IGMP Leave packet of the multicast group even you enable IGMP Snooping fast leave for the port. Fast leave is disabled by default. Related commands: igmp-snooping. 1-8

Use the igmp-snooping group-policy command to configure the filtering rule of multicast groups on a specified VLAN so as to control the access to IP multicast groups. You can configure only one ACL rule for each VLAN, and the new configured rule will replace the old one. Use the undo igmp-snooping group-policy command to remove the configuration. By default, no filtering rule is set in a VLAN. In this case, a host can join any multicast group. If an ACL is configured in a VLAN to filter multicast groups, hosts can join only those multicast groups that are permitted to join. # Create ACL2001 and configure the rule for basic ACL, using the source IP address as the destination multicast address. 1-9

Use the undo igmp-snooping host-aging-time command to restore the default value. This command is used to set the aging time of the multicast group member so that the refresh frequency can be controlled. When the group members change frequently, the aging time should be comparatively short, and vice versa. Related commands: igmp-snooping. # Set the aging time to 300 seconds.

Use the undo igmp-snooping nonflooding-enable command to restore the default. Note that if IGMP Snooping is not enabled on the VLAN (nor Layer 3 multicast), unknown multicast packets are flooded within their respective VLANs no matter whether this function is enabled or not. To suppress flooding of unknown multicast data packets within their respective VLANs, you need to enable IGMP Snooping in the VLANs and enable igmp-snooping nonflooding-enable globally. By default, unknown multicast data packets are flooded within their respective VLANs. 1-12
