vlan vlan-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN by its ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to 4094. If this option is not specified, this command takes effect for all VLANs. Usage guidelines This command is effective for the multicast groups that a port joins dynamically.
You can configure different ACL rules on a port in different VLANs. However, for a given VLAN, a newly configured ACL rule overrides the existing one. This command is effective for the multicast groups that a port dynamically joins. If you configure the port as a static member port for a multicast group, this command is not effective for the multicast group.The configuration made in proper interface view is only effective on the current port and takes preference over the global configuration.
Examples # Enable IGMP snooping for VLAN 2 and set the aging timer for the dynamic member ports in the VLAN to 300 seconds.

Views VLAN view Predefined user roles network-admin mdc-admin Parameters interval: Sets an aging timer (in seconds) for the dynamic router ports in a VLAN, in the range of 1 to 1000. Usage guidelines You must enable IGMP snooping for a VLAN before you execute this command for the VLAN. The configuration made in VLAN view is only effective on the current VLAN and takes preference over the global configuration.

Parameters interval: Sets the IGMP last-member query interval (in seconds), in the range of 1 to 5. Usage guidelines The IGMP last-member query interval determines the interval for sending IGMP group-specific queries and the maximum response time for IGMP group-specific queries. The global configuration is effective on all VLANs, but it has a lower priority than the configuration made in a specific VLAN. Examples # Set the IGMP last-member query interval to 3 seconds.
Related commands igmp-snooping max-response-time overflow-replace (IGMP-snooping view) Use overflow-replace to enable the multicast group replacement function globally.

You can specify multiple ports or port ranges by providing the argument in the form of interface-list = { interface-type interface-number [ to interface-type interface-number ] }. Usage guidelines The global configuration is effective for all specified ports, and it has the same priority as the configuration on the current port.
Usage guidelines Before you configure this command, enable IGMP snooping for the specified VLANs. Examples # Enable IGMP snooping for VLAN 2 through VLAN 10, and specify IGMPv3 snooping to run in these VLANs.

When you configure an RPF neighbor on a Layer 3 interface, which is a Layer 3 Ethernet interface, Loopback interface, or VLAN interface, you must specify the IP address of the neighbor rather than the type and number of the Layer 3 interface. The configured static multicast route might not take effect due to one of the following reasons: • The outgoing interface iteration fails.

If you configure the port as a static member port for an IPv6 multicast group, this command is not effective on the IPv6 multicast group. The configuration made in proper interface view is only effective on the current port and takes preference over the global configuration. Examples # Enable the IPv6 multicast group replacement function on Ten-GigabitEthernet 1/0/1 in VLAN 2.

• state-refresh-interval (IPv6 PIM view) • state-refresh-rate-limit (IPv6 PIM view) state-refresh-interval (IPv6 PIM view) Use state-refresh-interval to set the interval for sending state refresh messages. Use undo state-refresh-interval to restore the default. Syntax state-refresh-interval interval undo state-refresh-interval Default The state refresh interval is 60 seconds.
Views IPv6 PIM view Predefined user roles network-admin mdc-admin Parameters time: Specifies a time that the device waits before receiving a new refresh message, in the range of 1 to 65535 seconds. Examples # On the public network, configure the device to wait 45 seconds before it receives a new state refresh message.
preferred: Gives priority to the static RP if the static RP and the dynamic RP exist at the same time in the network. The dynamic RP takes effect only if no static RP exists in the network. If this keyword is not specified, the dynamic RP has priority, and the static RP takes effect only if no dynamic RP exists in the network or when the dynamic RP fails. Usage guidelines You do not need to enable IPv6 PIM on an interface that acts as a static RP.
Parameters interval: Sets the global interval for sending hello messages, in the range of 0 to 18000 seconds. If the value for this argument is 0, no hello messages are sent. Usage guidelines You can set the interval for sending hello messages in IPv6 PIM view or interface view. The configurations made in IPv6 PIM view are effective on all interfaces, and the configurations made in interface view are effective on only the current interface.
