config igmp check_subscriber_source_network
Purpose
Used to configure the flag that determines whether or not to check the subscriber source IP
when an IGMP report or leave message is received.
Syntax
config igmp check_subscriber_source_network [ ipif <ipif_name 12> | all ] [ enable |
disable ]
Description
When check_subscriber_source_network is enabled on an interface, any IGMP report or
leave message received by the interface will be checked to determine whether its source IP
is in the same network as the interface. If the check is disabled, the IGMP report or leave
message with any source IP will be processed by IGMP protocol.
Parameters
ipif_name
- Specifies the IP interface to be configured.
all
- All IP interfaces will be configured.
enable
- Enable the check state. The default state is enabled.
disable
- Disable the check state.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To enable igmp check_subscriber_source_network state on interface “System”:
DGS-3627:admin# config igmp check_subscriber_source_network ipif System enable
Command: config igmp check_subscriber_source_network ipif System enable
Success.
DGS-3627:admin#
show igmp check_subscriber_source_network
Purpose
Used to display the status of the IGMP report/leave message source IP check.
Syntax
show igmp check_subscriber_source_network { ipif <ipif_name 12>}
Description
Display the IGMP check_subscriber_source_network status for a single interface or all
interfaces.
Parameters
ipif_name
- Specified the IP interface to be displayed.
If no parameter specified, the system will display all interfaces.
Restrictions
None.

IP DIRECTED BROADCAST COMMANDS
The IP Directed Broadcast commands in the Command Line Interface (CLI) are listed (along with the appropriate
parameters) in the following table.
Command
Parameters
config ipif
<ipif_name 12> [{ipaddress <network_address> | vlan <vlan_name 32> | state
[enable | disable] | proxy_arp [enable | disable] {local [enable | disable]}} | bootp |
dhcp | ipv6 ipv6address <ipv6networkaddr> | ip_mtu <value 512-1712> |
dhcpv6_client [enable | disable] | ip_directed_broadcast [enable | disable]]
Each command is listed, in detail, in the following sections.
config ipif
Purpose
This command is used to configure the IP directed-broadcast state of the interface.
Syntax
config ipif <ipif_name 12> [{ipaddress <network_address> | vlan <vlan_name 32> |
state [enable | disable] | proxy_arp [enable | disable] {local [enable | disable]}} | bootp |
dhcp | ipv6 ipv6address <ipv6networkaddr> | ip_mtu <value 512-1712> | dhcpv6_client
[enable | disable] | ip_directed_broadcast [enable | disable]]
Description
This command will enabled or disabled the IP directed-broadcast state of a specified
interface.
An IP directed broadcast is an IP packet whose destination address is a valid broadcast
address of some IP subnet, but which originates from a node that is not a part of that
destination subnet.
The Switch that is not directly connected to its destination subnet and forwards an IP directed
broadcast in the same way that it would forward unicast IP packets to a host on that subnet.
When a directed broadcast packet reaches a router that is directly connected to its
destination subnet, and that packet is "exploded" as a broadcast on the destination subnet. It
only works on layer 3 Switch.
Parameters
The only highlighted parameter for this chapter is:
ip_directed_broadcast
- See below:
enable
- Enabled the IP directed-broadcast state of the interface.
disable
- Disabled the IP directed-broadcast state of the interface.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To set the IP Directed Broadcast state of System interface to enable:
DGS-3627:admin# config ipif System ip_directed_broadcast enable
Command: config ipif System ip_directed_broadcast enable
Success.
DGS-3627:admin#
To display the IP Directed Broadcast settings of System interface:
