Installing a QNX network
4 - 18 • • • Senstar 100 Installation guide
Previously, a problem existed with Dlink 530TX cards in that
older versions were detected by the nettrap query, but newer
ones were not.
The following driver contains the correct arguments for one of the newer cards:
Creating or editing the netmap file
The format for the
netmap
is:
Every computer on the QNX network must have an entry in the
netmap
file,
and the
netmap
file must exist on every computer. The following is an
example of the contents of a
netmap
file on a two-CU system:
1 1 0080c8 1d205a
2 1 0080c8 2b8dd9
The first line shows that node 1 is on network 1 and the MAC address of node
1’s Ethernet card is
0080c8 1d205a
. Every Ethernet card has a unique MAC
address, which is provided with the manufacturer’s documentation or labeled
on the card. Alternatively, you can determine the MAC address by entering the
following command on the prompt line:
# netinfo -l
You can also obtain the MAC address by starting the driver with the -
v
option.
For example, with the above noted card, enter the following command:
# Net.ether1000 -p300 -l1 -v &
This command will display various card settings, including the Ethernet card
MAC address.
Net.via
-x0x1106
-y0x3106
-I0 -l1 &
