Igmp Last-Member-Query-Interval - H3C S7500E Series Command Manual

Command Manual – Multicast
H3C S7500E Series Ethernet Switches
version-number: IGMP version, in the range of 1 to 3. By default, the system supports
IGMPv1, IGMPv2 and IGMPv3 concurrently.
Description
Use the igmp group-policy command to configure a multicast group filter on the
current interface.
Use the undo igmp group-policy command to remove the configured multicast group
filter.
Be default, no multicast group filter is configured, namely a host can join any multicast
group.
Note:
When you use an advanced ACL as a filter, the source address in the ACL rule is the
multicast source address specified in IGMPv3 reports, rather than the source address
in the IP packets.
The igmp group-policy command cannot be used in VLAN interface view. To
configure a multicast group filter on a specific Layer 2 port or ports, use the
igmp-snooping group-policy command or the group-policy command.
The igmp-snooping group-policy and group-policy commands are effective for
both IGMP Snooping–enabled VLANs and VLANs with IGMP enabled on the
corresponding VLAN interfaces.
Related commands: igmp-snooping group-policy, group-policy. Refer to
