ZTE 5250 switch forwards multicast stream on all ports, even with IGMP snooping enabled?

5250 series switch is designed as pure access level switch. This means on switch`s access ports are connects user devices and on uplink port – aggregation switch.

Multicast sources are connected on multicast router which is behind aggregation switch.

By default on 5250 series switches forwards multicast stream on all ports. To turn off this forwarding on port you must turn on multicast filter, command:

set port <portlist> multicast-filter {enable | disable}. 

zte(cfg)#set port 1,5-7,11 multicast-filter enable

This means that customer ports who uses IGMP snooping and needs multicast traffic must have enabled this filter. Other port which for example leads to next access switch must have disabled multicast filter.
