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#
