● Using the data interface, the ETERNUS CS800 needs to connect to a backup host that
is on the 10.50.50.x subnet. Because this host is not on the same subnet as the data
interface, the ETERNUS CS800 cannot communicate with the host unless you specify
routing information in the Routing Details section.
In this example, you would specify 10.50.50.0 for destination network, 255.255.255.0
for the destination netmask, and 10.20.20.1 as the destination gateway.
I
The gateway specified in the IP Address Table section is for incoming traffic to the
interface. The gateway specified in the Routing Details section is for outgoing traffic
from the interface.

Example 2: Segments on the Same Subnet and Target on a Different Subnet
In the example below (see Figure 184), the ETERNUS CS800 has two segmented inter-
faces, one for data and management traffic, and one for replication traffic:
● The source ETERNUS CS800 management/data IP address and the source
ETERNUS CS800 replication IP address are on the same subnet (192.168.10.x). The
target ETERNUS CS800 IP address is on a different subnet (192.168.20.x)
