z 

After the maximum number of multicast groups is reached, the interface will not join any new 

multicast group.  

z 

If you configure the maximum number of multicast groups allowed on the interface to 1, a new 

group registered on the interface supersedes the existing one automatically.  

z 

If the number of existing multicast groups is larger than the configured limit on the number of joined 

multicast groups on the interface, the system will remove the oldest entries automatically until the 

number of multicast groups on the interface comes down to the configured limit.  

 

# Configure to allow a maximum of 100 multicast groups to be joined on VLAN-interface 10.

acl-number: Basic ACL number, defining a multicast group range. The value ranges from 2,000 to 

2,999.  

1: Configures the interface to accept only IGMPv1 report messages.  

2: Configures the interface to accept only IGMPv2 report messages (default).  

port interface-list: Configures a multicast group filter on the specified port or ports. With the interface-list 

argument, you can define one or more individual ports (in the form of interface-type interface-number) 

and/or one or more port ranges (in the form of interface-type  interface-number1  to  interface-type 

interface-number2, where interface-number2 must be greater than interface-number1). The total 

number of individual ports plus port ranges cannot exceed 10. For port types and port numbers, refer to 

the parameter description in the “Port Basic Configuration” part in this manual. 

 

In LoopBack interface view, this command does not support the port interface-list option.
