entry or all multicast MAC address entries on the current port.
Each multicast MAC address entry contains the multicast address, forwarding port, and VLAN ID
information.

multicast-source-deny

Syntax
multicast-source-deny [ interface interface-list ]
undo multicast-source-deny [ interface interface-list ]
View
System view, Ethernet port view
Parameters
interface interface-list: Enables the multicast source port suppression feature 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.
Description
Use the multicast-source-deny command to enable the multicast source port suppression feature.
Use the undo multicast-source-deny command to restore the default setting.
By default, the multicast source port suppression feature is disabled on all the ports.
With the multicast source port suppression feature enabled on a port, the port drops all multicast data
packets while it permits multicast protocol packets to pass. This feature is useful for rejecting multicast
traffic from unauthorized multicast source servers connected to the switch.
