DWS-3160 Series Gigabit Ethernet Unified Switch CLI Reference Guide 45-15 config mld_snooping data_driven_learning Description This command is used to enable or disable the data-driven learning of an MLD snooping group. When data-driven learning is enabled for the VLAN, when the Switch receives the IP multicast traffic, on this VLAN, an MLD snooping group will be created. That is, the learning of an entry is not activated by MLD membership registration, but activated by the traffic. For an ordinary MLD snooping entry, the MLD protocol will take care the aging out of the entry. For a data-driven entry, the entry can be specified not to be aged out or to be aged out by the aged timer. When the data driven learning is enabled, and the data driven table is not full, the multicast filtering mode for all ports is ignored. That is, the multicast packets will be forwarded to router ports. If the data driven learning table is full, the multicast packets will be forwarded according to the multicast filtering mode. NOTE: If a data-driven group is created and MLD member ports are learned later, the entry will become an ordinary MLD snooping entry. That is, the aging out mechanism will follow the ordinary MLD snooping entry. Format config mld_snooping data_driven_learning [all | vlan_name | vlanid ] {state [enable | disable] | aged_out [enable | disable] | expiry_time }(1) Parameters vlan_name - Specifies the VLAN name to be configured. - Enter the VLAN name here. vlanid - Specifies the VLAN ID to be configured. - Enter the VLAN ID list here. all - Specifies that all VLANs are to be configured. state - (Optional) Specifies to enable or disable the data driven learning of MLD snooping groups. By default, the state is enabled. enable - Enter enable to enable the data driven learning state. disable - Enter disable to disable the data driven learning state. aged_out - (Optional) Enable or disable the aging out of entries. By default, the state is disabled. enable - Enter enable to enable the aged out option. disable - Enter disable to disable the aged out option. expiry_time - (Optional) Specifies the data driven group lifetime, in seconds. This parameter is valid only when aged_out is enabled. - Enter the expiry time value here. This value must be between 1 and 65535 seconds. Restrictions Only Administrators, Operators and Power-Users can issue this command. Example To enable the data driven learning of an MLD snooping group on the default VLAN: 460
