You may do such test:
I have tested this dpdk example. It works. Only this example gets failed.
ip neigh show
ans> ip neigh show
ANS IP neigh table
ip link show
veth0: port 0 state DOWN mtu 1500
link/ether 00:1b:21:c0:51:b8
IPV4 checksum offload enable
UDP checksum offload enable
TCP checksum offload enable
TCP TSO offload enable
Max allowed number of segments: 255
RX packets:0 errors:0 dropped:0
TX packets:0 errors:0 dropped:0
Something wrong with your nic.
The port is down.
In my network card, port as a different name other than veth0
. But i have set hugepages and bind network card in dpdk module.
I have fixed Port down issue. But still it does not bind an IP for that.
Checking link status ...............done
Port 0 Link Up - speed 1000 Mbps - full-duplex
USER8: main loop on lcore 1
USER8: -- lcoreid=1 portid=0 rxqueueid=0
IP assigning
ans> ip addr show

inet addr: 10.0.0.2/24
ans> ip add del 10.0.0.2/24 dev veth0
Bad arguments
ans> ip addr del 10.0.0.2/24 dev veth0
Del IP address successfully
ans> ip addr del 192.168.20.10/24 dev veth0
Del IP address failed, error code 17
ans> ip addr add 192.168.20.10/24 dev veth0
Add IP address successfully

ans> ip addr show
veth0: mtu 1500
link/ether 08:00:27:0c:45:ab
inet addr: 192.168.20.10/24
But I still can not ping to it even inside the VM.
ans is userspace tcp/ip stack, you can't ping to it from linux kernel inside the VM, you shall ping to it from another vm.
Yes, VM to VM ping was working fine. Thanks for the support.
Good morning Sachith, I have been facing what I think is a similiar issue to yours. I know the issue is closed, but maybe you can provide me some help. I have 2 interfaces, one is NATted and the other one is for dpdk binding purposes. Within my Ubuntu 16.04 I have isntalled dpdk and dpdk-ans, and run it with: ./ans -c 0x4 -n 1 --base-virtaddr=0x2aaa2aa0000 -- -p 0x1 --config="(0,0,2)" --enable-kni --enable-ipsync
I cannot ping 10.0.0.2 from other VM. Do you know what can be happening or would it be bigger issue to you to explain me how to get connection from one VM with DPDK-ANS to another VM? Thank you very much in advance
You may try the command "./ans -c 0x4 -n 1 --base-virtaddr=0x2aaa2aa0000 -- -p 0x1 --config="(0,0,2)""
Good evening. Thank you for your answer. Without ipsync I am also unable to ping the dpdk-ans stack. This is my configuration: VM1(DPDK-ANS): Interface NAT: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:0c:29:8c:c9:bf brd ff:ff:ff:ff:ff:ff inet 192.168.153.148/24 brd 192.168.153.255 scope global dynamic ens33 valid_lft 1564sec preferred_lft 1564sec inet6 fe80::b286:4947:3db5:fdfe/64 scope link valid_lft forever preferred_lft forever
DPDK-ANS conf: ans> ip addr show
veth0: mtu 1500 link/ether 00:0c:29:8c:c9:c9 inet addr: 10.0.0.2/24 ans> ip route show
ANS IP routing table 10.0.0.0/24 via dev veth0 src 10.0.0.2 10.10.0.0/24 via 10.0.0.5 dev veth0
From another VM in the same network (i can ping the NAT interface), i cannot ping 10.0.0.2. Could you please make me a short explanation about how to do it? I cannot find anything on the userguide.
Thank you very much in advance.
Thanks for your talks! It is helpful!
I have
dpdk-ans
running in my VirtualBox - Centos-7 environment.I can run everything without error
I ran ->
./build/ans -c 0x2 -n 1 -- -p 0x1 --config="(0,0,1)"
Opened another one and ran
./build/anscli
insidedpdk-ans/ans
But I can not ping to
10.0.0.2
from VM or my host PC. I have changed the IP but no luck.I would like to join
dpdk-ans
Slack community. Please let me know how to join.
