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 provided 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.
The configuration files for the DHCP server are in the /opt/bladeservices/etc
directory. The DHCP configuration file name is pdevn-dhcpd.conf.
The switch VSW is used for internal data/packet exchange between the DSPs.
Place the DSP firmware images in the root directory of the TFTP server (or a subdirectory
of TFTP server). The default is /var/lib/tftpboot directory.
OctSetup creates pcie1820/pdevn directories in the TFTP root directory. Where ‘n’ is
the PCI-bus number of the card. Therefore, find a pdevn directory for every card in the
host. For information on how to find PCI-bus number, see section
Be aware that 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.
