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 that 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 <vlan_name> | vlanid
<vlanid_list>] {state [enable | disable] | aged_out [enable | disable] | expiry_time <sec 1-
65535>}(1)
Parameters
all - Specify that all VLANs are to be configured.
vlan_name - Specify the VLAN name to be configured.
<vlan_name> - Enter the VLAN name here.
vlanid - Specify the VLAN ID to be configured.
<vlanid_list> - Enter the VLAN ID list here.
state - (Optional) Specify 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) Specify the data driven group lifetime, in seconds. This parameter is
valid only when aged_out is enabled.
<sec 1-65535> - Enter the expiry time value here. This value must be between 1 and 65535
seconds.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
Example
To enable the data driven learning of an MLD snooping group on the default VLAN:
DES-3200-28/ME:admin#config mld_snooping data_driven_learning vlan default
state enable
Command: config mld_snooping data_driven_learning vlan default state enable
Success.
