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.
In system view, if no port or port list is specified, the multicast source port suppression feature is
enabled on all the ports of the switch; if one or more ports or port lists are specified, the multicast
source port suppression feature is enabled on the specified ports.
In Ethernet port view, you can use the command to enable the multicast source port suppression
feature on the current port only.
