  Note: 
z  this function takes effect on condition that the client supports IGMP V2.  
z  After configuring this command, when there are multiple users at one port, the 
of one user may cause the loss of multicast service of other users in this 
leaving 
group. 
 
2.2.6  Setting the maximum number of multicast groups permited on a port 
Perform the following configuration in Ethernet port view.

B r of multicast groups permited on a port is 1000. 
2.2.7  Configuring IGMP Snooping Filter 
, by 
configuring some multicast filtering ACLs for users on the different switch ports, so that 
m sets.  
In practice, when ordering a multicast program set, the user originates an IGMP report 
 it drops the IGMP report packet and 
y default, the maximum numbe
IGMP snooping filter function can limit the programs that users can order
different users can order different progra
packet. Upon receiving the packet, the switch first compares it against the multicast 
ACLs configured on the inbound port. If allowed, the switch then adds the port to the 
forward port list of the multicast group; otherwise,
no data flow then will be sent to this port. Thus the switch can control users’ multicast 
program ordering.  
Perform the following configuration in Ethernet port view.
