User Guide Quick Start Guide
1. Assign an IP address on the 192.168.1.x subnet to the interface for function 0 (in the previous example, it is enp1s0f0).
Example:
sudo ifconfig enp1s0f0 192.168.1.20 up
# OR
sudo ip addr add 192.168.1.20/24 dev enp1s0f0
2. Check the new IP address with either an
ifconfig
or
ip addr show
command. The PS225 (the ARM host on the
PS225) can now be pinged.
Example:
$ ping 192.168.1.10
PING 192.168.1.10 (192.168.1.10) 56(84) bytes of data.
64 bytes from 192.168.1.10: icmp_seq=1 ttl=64 time=0.131 ms
64 bytes from 192.168.1.10: icmp_seq=2 ttl=64 time=0.046 ms
...
Figure 6 shows the connectivity of the first interface on the x86 host and the first interface on the ARM side. 192.168.1.20 is
assigned to enp1s0f0 (on the x86 host) and 192.168.1.10 to enP8p1s0f0np0 on the ARM host on the PS225. These two
interfaces are connected through Nitro (red arrow).
NOTE:
As shown in Figure 6 , each interface can send packets out on the 25GbE port (blue arrow for the x86 enp1s0f0
host interface and green arrow for the ARM enP8p1s0f0np0 interface).
