Dynamips Server on way to begin CCIE training

These past two days have been a pain in my ass with these Quad NICS. I have had some moments were I have raged on networking equipment or machines but I have never been so frustrated. Long story short with older quad NICS some will show up as one MAC address for four NICS. So of course Fedora(Dynamips OS) Freaks out on its ifconfig and gives it 4 interfaces with the same MAC for example…

eth8-eth7 Link encap:Ethernet HWaddr 00:03:BA:6D:76:AA
eth6-eth7 Link encap:Ethernet HWaddr 00:03:BA:6D:76:AA
eth5-eth7 Link encap:Ethernet HWaddr 00:03:BA:6D:76:AA
eth7 Link encap:Ethernet HWaddr 00:03:BA:6D:76:AA

after days of dropping the drive, manually adding mac addresses, not loading the driver in the Kernel I just about decided to just purchase another few. I was extremely lucky I found out a place that has 4 of them needed. They happened to have the Sun 501-4366. I found that the Sun quad NICs with a Intel chipset work great, I am even running a 64 bit OS Fedora Core 14 without any issues. So these other NICs I purchase I put the first one in and it worked…. I really did not want to test the other 3 I was just happy it worked.

So I have everything plugged in from each one of my nics according to the following topology from INE.

Here is what it looks like in my new place.

Here is my cost sheet.

    Why wouldn’t you recommend the Sun 501-4366?

    Is “[T]hese past two days have been a pain in my ass with these Quad NICS” in reference to the Sun 501-4366? If so, how did purchasing more Sun 501-4366s resolve the MAC issue?

    Last, do you know if the Sun 501-4366 will work on any Windows systems?

    Thanks a bunch–in the process of researching my own CCIE lab.

      If you read about the problems I faced in the entire paragraph it will tell you. These will only work on Unix/Linux OS’s. They have 4 interfaces which should give you 4 unique mac addresses but, the OS does not see that it sees 4 identical mac addresses and makes really weird interfaces. Some cards do that, some do not depending on if they do or do not have the Intel chipset.

        I just bought 4 of these cards (with one original manual) and one of those cards have all MAC addresses same, so I just changed them using ethtool/ip command and it works. Manual says it could work in switched mode, I suspect that’s the issue. But it’s working correctly.

    I’m trying to build a similar lab infrastructure.
    Please, could you specify which 3550 you are using? SMI/EMI? 48/24? I cannot see it clearly in the photo.

    What OS are you using? I had a Ubuntu 10.10 box with the Sun cards in them, and everytime I connected a quad card, the system came to a screeching halt and would lock up…

    I see you are running over 2G of ram….are you having any issues with the connections?

    • danielhertzberg  On February 1, 2012 at 6:09 am

      Fedora 14, nope Im not sure why I would have any issues its a AMD phenom II X4 with 16gb of ram.

      • Chuck Brantley  On February 1, 2012 at 8:34 am

        Not saying you should have issues, but there are articles online saying these cards don’t work with more than 2G of ram. I was trying to figure out if I was having kernel issues or hitting the memory issue. I will try to load Fedora on my box and see if I can get them to work. Did you have a problem with interface numbering or them changing upon reboot?


      • danielhertzberg  On February 1, 2012 at 8:45 am

        Nopes, in RHEL distros (fedora,Centos) I never had a problem… I really only run Fedora for the most part. It should create a file within /etc/sys-interfaces/ and keep the eth0-12 interfaces like they are. If you run into any issues feel free to ask.
