H3C S7500E Series Ethernet Switches Chapter 1 IGMP Snooping Configuration Commands
1-13
z This command works on IGMP Snooping–enabled VLANs and VLANs with IGMP
enabled on the corresponding VLAN interfaces.
z If you do not specify any VLAN in Ethernet interface view, the command will take
effect on the port no matter which VLAN the port belongs to; if you specify a VLAN
or multiple VLANs, the command will take effect on the port only if the port belongs
to the specified VLAN(s).
z If you do not specify any VLAN in port group view, the command will take effect on
all the ports in this group no matter which VLANs these port belong to; if you
specify a VLAN or multiple VLANs, the command will take effect on those ports in
this group that belong to the specified VLAN(s).
z If the specified ACL does not exist or the ACL rule is null, all multicast groups will
be filtered out.
z You can configure different ACL rules for a port in different VLANs; for a given
VLAN, a newly configured ACL rule will override the existing one.
