Dual TCP/IP Configuration Examples

Use a virtual private network (VPN) to insulate host-to-library traffic from other

interference, such as irrelevant broadcasts.
Network Broadcast Issues on a Shared Network
Broadcasts sent to all network nodes may be directed to the library. The library cannot
efficiently process requests while it is receiving these irrelevant broadcasts. As a result,
the host may determine the connection to the library is lost.
Heavy network traffic can also overwhelm the Ethernet controller on the HBC/HBCR
card. As a result, the controller continuously resets.
ARP Floods on a Shared Network
The SL3000's processor can be overwhelmed by floods of address resolution protocol
(ARP) broadcasts. You should connect the library behind a switch or router.

ACSLS Dual TCP/IP and Shared Subnets Example
In this example, the ACSLS server and the library share two separate subnets. The
SL3000 uses a one-to-one relationship with the network interfaces on the ACSLS
server. The network interface card on subnet 192.168.0/23 connects to port 2B and the
network interface card on subnet 192.168.1/23 connects to port 2A.

Routing

Force a relationship by using the UNIX route commands. For more information, see
the ACSLS Administrator's Guide and SL3000 Installation Manual.

In this example, the ACSLS server contains two network interfaces that reside on two
separate subnets. Both interfaces pass through a public network and into two different
