Irected Broadcast Forwarding Disabled - Cal Amp Dataradio HiPR-900 User Manual

Directed broadcast forwarding
Directed broadcast forwarding
In the example in Figure 55, directed broadcast forwarding is enabled on the Master unit and dis-
abled on the Remote (1) unit. If Sender sends a packet to destination address 172.30.1.255, the pack-
et would be discarded by Remote (1), it would not reach Remote Host (1), Remote Host (2), and
Remote Host (3).
If the user wants the Master unit to do the discarding of the directed broadcast packets, then the di-
rected broadcast forwarding must be disabled on the Master unit itself.
LIMITED BROADCAST
The "Limited Broadcast" radio buttons let the user select whether the unit must forward or not limited
broadcast packets. Upon reception of a limited broadcast packet, the unit takes the following actions:
•
Keeps a copy for itself (passes to internal applications, if any).
•
If limited broadcast packets can be forwarded: Sends a copy of the packet from all interfaces except
from the one that received the packet.( i.e. if the packet was received by Ethernet Interface, it will be
sent out by RF Interface and vice versa)
•
If limited broadcast packets cannot be forwarded: Silently discards the packet.
