im using the NetFPGA v 3.0.and im having issues while running the openflow_switch.bit. The switch and controller do communicate with each other but when i connect 2 hosts PC’s with my NetFPGA openflow switch, the hosts are unreachable. No traffic detected on wireshark on the nf2c0 and nf2c1 interfaces of the netFPGA.Is this problem due to the netFPGA package version? Will the openflow_switch.bit run on the v.2.2.0 verison?Im stuck on this for quiet a while. Waiting for your reply.Thanks,Mustafa
if u type ifconfig, do all the 4 interfaces (nf2c0, nf2c1, nf2c2 n nf2c3) get shown?
Yes. All interfaces are up. Selftest is also successful.
so basically u r not able to perform the regression tests isnt it?
yea. I ran regression test but it was stuck at one test. and was taking too long. the reason was we where using a 100 Mbps NIC for it but the required one was a 1Gbps. So we skipped it and moved on.
I cant up the interfaces…Karen
hi karen.. did u try these commands?ifconfig nf2c0 upifconfig nf2c1 upifconfig nf2c2 upifconfig nf2c3 upif the interfaces are still not getting detected then there is a problem with your netfpga base installation..
hello Pharic,I have one maybe strange question, that isn’t fully corelated with things on your blog.I have put NetFPGA “up”, and connected two cables to two nf ports. On the other side of the cables are PC-s. The trafic goes betwenn pc-s, through netfpga and that all function well, but I’m unable to see trafic on wireshark? There is standing 0 by the nf2c0 and nf2c3 ports. Netfpga is part of the open flow network, and I have defined netfpga as a hub. On other hand, when i define netfpga as a router, i can see traffic on wireshark. Is that wireshark unability to detect traffic linked with defined functions of netfpga? My explanation is that, when I define she as a hub, she functions as a “separate device”, that have not need to comunicate with rest of the “cube”, and there for is no trafic deteced on wireshark?Tnx for reading this, and I’ll apriciate your help.
Pharic, can you share how you got the traffic to go betwenn pc-s, through netfpga?
hi…can u please tell me is there any driver for netfpga card?
hi.. as far asi know there are no specific drivers that are available.. the netfpga package itself is a driver (AFAIK)..
Thank u……. how to get the packets for netfpga?
Hi…..Pharic….can u tell me the meaning for the following command line?yum -y –enablerepo=jpackage-generic-nonfree install java-1.6.0-sun-compat.i586.we didn’t get the result as u spacified. please guide me.
its a command to install java runtime environment…
Hi! I don't have much experience with NETFPGA so excuse me if my question is stupid. I have read few tutotials about NETFPGA installation, and now I am confused because I don't know is this step required or I can bypass it and instead install base package, Java GUI, RPM Forge and others. (?)
hi.. i think this step has to be done only if u need old package of netfpga.. if u r using a project that needs the latest package i believe u cud just skip this step..
I am trying to form network using NetFPGA. There I should use NetFPGA as router, switch , packet generator ... You wrote in some of your posts that is necessery to use base package version 2.1 (not the newest) to implement ipv4 reference router. Can I use just that package and bypass this step?
And another question... I can't find any documentation about Ethernet switch implementation on netfpga.org site. Did you work something similar?
for the first question, yes you could do that..for the second, i was working on PTP-enabled routers.. i checked the netfpga site and yes they do not have a guide for ethernet switch.. mayb you could try googling but i guess its pretty difficult to find help..
Ok. Thank you!
I have a problem when I try to install matlab program on Linux system (centros 6), could you help me to sort out this problem,
sure.. did u chk this post i have written abt installing matlab on linux?http://pharic.blogspot.com/2013/08/installing-matlab-on-linux.html
