IP Addresses
Note: The eight host network connections on the DSN-3200 may be LAG'd
(Link Aggregate Group) together to form higher speed links. This capability
is also known as trunking.
The default configuration of these ports is shown above. Host Network
Connections 0 through 3 all share IP address 192.168.2.1. Host Network
Ports 4 through 7 share IP address 192.168.3.1. In our example we will
only attach to the first group.
