The l2-multicast static-group dot1q command configures a dot1q sub-interface as a static multicast group member interface.
The undo l2-multicast static-group dot1q command cancels the configuration.
By default, a dynamic member interface is used.
| Parameter | Description | Value |
|---|---|---|
| source-address source-address | Specifies a multicast source address. |
The value can be a Class A, Class B, or Class C address, in dotted decimal notation. |
| group-address group-address | Specifies a multicast group address. |
The value ranges from 224.0.1.0 to 239.255.255.255, in dotted decimal notation. |
| vid vid | Specifies a VLAN ID for a Dot1q termination sub-interface. |
The value is an integer ranging from 1 to 4094. |
| vsi vsi-name | Specifies a VSI. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
Usage Scenario
If hosts connected to an interface need to regularly receive data for a multicast group or a source-specific multicast group, the l2-multicast static-group dot1q command can be used to configure the interface as a static member interface.
Static member interfaces can be configured on different positions on a network to enable users to receive data for specific multicast groups or source-specific multicast groups regularly.Prerequisites
IGMP snooping has been configured globally and in a VSI.
Configuration Impact
A static member interface does not respond to IGMP Query messages. After the undo l2-multicast static-group command is run on a static member interface, the interface does not initiate an IGMP Leave message.
If the l2-multicast static-group command is run more than once, all configurations take effect.Precautions
If the number of (S, G) entries relevant to a group has reached the maximum value (128), no static entry will be created after the l2-multicast static-group command is run. This means that no entry relevant to a static multicast group will be generated even after the reset igmp-snooping group all command is run in the system view to refresh entries.
