Enabling All-Subnet Broadcasting on an Interface
An all-subnet broadcast (ASB) datagram has a destination address equal to the
broadcast address for an entire network (all subnets). For example, if a network
interface serves the subnet 128.10.2.1 with a subnet mask of 255.255.255.0, the IP
router considers any datagram with a destination address of 128.10.255.255 or
128.10.0.0 to be an ASB datagram.
By default, IP does not flood ASB datagrams. You can use the BCC or Site
Manager to turn this feature on and off as required.
Using the BCC
To enable or disable all-subnet broadcasting, navigate to an IP interface prompt
(for example,
stack; eth 2/2; ip/2.2.2.2/255.255.0.0
) and enter:
all-subnet-broadcast
<state>
state
is one of the following:
enabled
disabled
(default)
For example, the following command causes IP to flood ASB datagrams out
interface 2.2.2.2:
ip/2.2.2.2#
all-subnet-broadcast enabled
ip/2.2.2.2#
4. Click on the interface that you want to edit. Site Manager displays the parameter
values for that interface in the IP Interface
List window.
5. Set the
Redirect
parameter. Click on
Help
or see the parameter description on page
A-11
.
6. Click on
Apply
, and then click on
Done
. You return to the Configuration Manager
window.
