
At boot time, the numbering of the network devices of the card is completed. This
numbering is arbitrary and differs from system to system. Use
ethx
,
ethy
and
ethz
as
placeholders in the above example set up.

No network device is connected to
ethy
. The pseudo device
ethy
is only to access the
CPLD. Avoid finding a link at this device and configuring an IP-address used to access.

It is not required to define IP address for the network devices
ethx
and
ethz
. The DSPs
use a MAC-based protocol and not an IP-based protocol. However, you can identify the
MAC address of the network device and configure the IP address for these devices.

The default VLAN ID of the DSP ports at MSW is
999
. It indicates that the switch adds the
VLAN tag with ID
999
for every untagged packet received at a port.

When the DSP requests an IP address from the DHCP server, the server selects an arbitrary
IP-address from the range
192.168.100.[10-21]
. There is no fixed relation between
IP-address and DSP number. Additionally, there is no need to prefer this particular subnet
192.168.100.0.
, you can select any subnet.

If a second card is installed in the system, the subnet for that card is
192.168.101.0.
The system that octSetup uses is
192.168.[100 + card#].0
. You can select any
system or subnet.

MSW and VSW are identical from functional point of view. They route the two
links of a DSP to the host.

CPLD is used for board management and control and has no access to the DSPs.
When you develop an application running on the DSPs, either define your own VLAN for
your application packets or remove or disable
VLAN 999
after the DSPs has loaded its
firmware image. You can select any other ID except zero to develop the application after the
DSPs have loaded their firmware images.
