period of time. The IP ARP table relates each (wired or wireless)
station's IP address to its physical MAC Address so the base station
knows how to address Ethernet messages bound for a particular IP
Address. If you disable (uncheck) ARP cache aging, the base station will
not remove entries from this table, and it may fill up over time. The base
station can hold up to 10,000 entries in the ARP table.
Enable Multicast Pruning-- Select this checkbox if you want to enable
multicast pruning.
IP multicast is a bandwidth-conserving technology that reduces traffic by
simultaneously delivering a single stream of information to potentially
thousands of corporate recipients and homes.
Without multicast pruning, multicast traffic is treated in the same manner
as broadcast traffic. That is, it is forwarded to all ports. However, with
multicast pruning, you choose to permit only the packets that are a part
of multicast group in your network. Multicast pruning generates no
additional network traffic, allowing you to significantly reduce multicast
traffic passing through your switch.
Add Direct IP Routes
Clicking the Add/Direct button displays the Add Direct IP Route screen,
which allows you to add new direct IP routes.
When the Secure Data Mode station has two or more IP subnets directly
attached to its different interfaces, it can route IP packets between those
subnets using a direct route. This screen is used to specify the direct
routes for each of the interfaces on the Secure Data Mode Bridge/Router.
A direct route consists of an IP address, which specifies the basic IP
address to route, a Subnet Mask which defines the basic class of IP
addresses that will be routed, and an interface number which specifies
where the IP subnet is attached. When IP packets addressed to a system
arrives at the Secure Data Mode station, the Secure Data Mode station
will send it directly to the target machine on the interface specified.
