Ensure that the subnet on which you want broadcast packets using IP direct broadcast
is not directly connected to the Internet.
Configure a routed VLAN interface (RVI) for the subnet that will be enabled for IP direct
broadcast. See "Configuring Routed VLAN Interfaces (CLI Procedure)" on page 1601 or
"Configuring VLANs for EX Series Switches (J-Web Procedure)" on page 1597.
NOTE: We recommend that you do not enable IP directed broadcast on
subnets that have a direct connection to the Internet because of increased
exposure to denial-of-service (DoS) attacks.
To enable IP directed broadcast for a specified subnet:
Add the target subnet's logical interfaces to the VLAN:
1.
[edit interfaces]
user@switch# set ge-0/0/0.0 family ethernet-switching vlan members v1
user@switch# set ge-0/0/1.0 family ethernet-switching vlan members v1
Configure the Layer 3 interface on the VLAN that is the target of the IP directed
2.
broadcast packets:
[edit interfaces]
user@switch# set vlan.1 family inet address 10.1.2.1/24
Associate a Layer 3 interface with the VLAN:
3.
[edit vlans]
user@switch# set v1 l3-interface vlan.1
Enable the Layer 3 interface for the VLAN to receive IP directed broadcasts:
4.
[edit interfaces]
user@switch# set vlan.1 family inet targeted-broadcast

To trace the operations of individual router or switch interfaces, include the
statement at the

[edit interfaces interface-name]
traceoptions {
flag flag;
}
You can specify the following interface tracing flags:
—Trace all interface operations.
all
event —Trace all interface events.
