33
Parameters
vlan vlan-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN by its
ID or a range of VLANs in the form of start-vlan-id to end-vlan-id. The VLAN ID is in the range of 1 to
4094.
Usage guidelines
If you do not specify any VLAN when using this command, the command takes effect on all VLANs to
which the interface belongs.
If you specify one or more VLANs, the command takes effect on the specified VLANs to which the
interface belongs.
Examples
# Disable GigabitEthernet 2/1/1 from becoming a dynamic router port in VLAN 2.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] igmp-snooping router-port-deny vlan 2
igmp-snooping source-deny
Use igmp-snooping source-deny to enable multicast source port filtering on a port to filter out all the
received multicast data packets. This allows the port to connect to only multicast receivers rather than to
multicast sources.
Use undo igmp-snooping source-deny to disable multicast source port filtering on the current port.
Syntax
igmp-snooping source-deny
undo igmp-snooping source-deny
Default
Multicast source port filtering is disabled, and the port can connect to both multicast sources and
multicast receivers.
Views
Layer 2 Ethernet interface view
Predefined user roles
network-admin
Usage guidelines
The command is supported on the following hardware:
MSR routers installed with the Layer 2 switching module HMIM 24GSW, HMIM 24GSW-POE, or HMIM
8GSW.
This configuration is only effective on the current port, and it has the same configuration priority as the
global configuration.
Examples
# Enable source port filtering for multicast data on GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] igmp-snooping source-deny
