Use the undo igmp-snooping group-policy command to remove a multicast group filter on the 

current port(s).  

By default, no multicast group filter is configured on an interface, namely a host can join any valid 

multicast group. 

Note that:  

z 

If you do not specify any VLAN when using this command in Ethernet interface view or Layer 2 

aggregate interface view, the command will take effect for all VLANs the interface belongs to; if you 

specify a VLAN or multiple VLANs, the command will take effect only if the interface belongs to the 

specified VLAN(s).  

z 

If you do not specify any VLAN when using this command in port group view, the command will 

take effect on all the ports in this group; if you specify a VLAN or multiple VLANs, the command will 

take effect only 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.

2: System level 

interval: Dynamic member port aging time, in seconds. The effective range is 200 to 1,000.  

Use the igmp-snooping host-aging-time command to configure the aging time of dynamic member 

ports in the current VLAN.  

Use the undo igmp-snooping host-aging-time command to restore the default setting.  

By default, the aging time of dynamic member ports is 260 seconds.  

This command takes effect only if IGMP Snooping is enabled in the VLAN.
