Multicast
Multicast
Disabled (Default), Enabled – Controls forwarding of
Multicast packets (based on the “Multicast Address
List”)
Multicast can be used when “one-to-many” communi-
cation is required.
Mobile unit address
This multicast address represents the "All Mobile"
group. When a Base station receives
an IP packet on its Ethernet interface and the destina-
tion IP address matches this multicast address,
the IP packet is forwarded over the RF interface to all
the Mobile units. The Mobile units will pass
this packet to their internal applications.
Multicast Address List
Add / Delete Address
The multicast address list is used to enter multicast
addresses for the various "Mobile Hosts" groups.
When a Base station receives an IP packet on its
Ethernet interface and the destination IP address
matches one of these address, the IP packet is for-
warded over the RF interface to all the Mobile units.
If multicast forwarding is enabled on the Mobile units,
the IP packet will be forwarded to the Mobile's Ethernet
interface, Mobile Hosts will then be able to receive the
packet.
The Mobile units have some additional filtering capa-
bilities.
To add an address to the Multicast List:
Select the “Add” option button and type in the dialog
box the new address to be added to the read-only
“Address List”. Note that only valid multicast ad-
dresses will be accepted and displayed.
To delete an address from the Multicast List: Select the
“Delete” option button and type in the dialog box the
address to be deleted from the “Address List”.
Address List
Read-only listing. Window expands downward as
needed to show all addresses in the list.
When an IP packet is received on the Ethernet side of
the unit and the destination IP address matches one of
the multicast IP addresses in this list, it is forwarded
over the RF interface.
Remote units will send it over their Ethernet interface.
