When 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 IGMP member ports
are learned later, the entry will become an ordinary IGMP snooping
entry. That is, the aging out mechanism will follow the ordinary IGMP
snooping entry.
Syntax config igmp_snooping data_driven_learning [all | vlan_name
<string 32> | vlanid <vidlist>] {state [enable | disable]
expiry_time <sec 130-153025> aged_out [enable | disable]}
Description The config igmp_snooping data_driven_learning command is
used to enable or disable the data driven learning of an IGMP
snooping group.
Parameters all – Specifies all VLANs to be configured.
vlan_name <string 32>
− The name of the VLAN for which IGMP
snooping is to be configured. Up to 32 characters can be used.
vlanid <vidlist>
−
Specifies the VLAN ID to be configured.
state [enable | disable] – Specifies to enable or disable the data
driven learning of an IGMP snooping group. The defaule is enabled.
expiry_time <sec 130-153025>
−
Specifies the data driven group
lifetime in seconds. This parameter is valid only when aged_out if
enable . This value must be between 130 and 153025 seconds.
age_out [enable | disable] – Specifies to enable or disable the aging
out of the entry.By default, the state is enabled.
Restrictions Only administrator or operator-level users can issue this command.
Example usage:
To enable the data driven learning of an IGMP snooping group on the defaultVLAN:
DGS-1210-28MP/ME:5# config igmp_snooping data_driven_learning vlan_name
default
Command: config igmp_snooping data_driven_learning vlan_name default
Success.
DGS-1210-28MP/ME:5#
config igmp_snooping data_driven_learning
Purpose To configure the maximum number of groups that can be learned by
data driven.
When the table is full, the system will stop the learning of the new
dada-driven groups. Traffic for the new groups will be dropped.

Description The config igmp_snooping data_driven_learning command is
used to configure the maximum number of groups that can be
learned by data driven.
Parameters max_learned_entry <integer 1-1024> – Specifies the maximum
