Thanks to Quanta, the company no one has ever heard of, but which company makes all of Facebook’s servers and switches, for 6 or 7 grand, you can now get a 48 port Ethernet switch with 48 10GB ports, 8 of which are fiber. That’s nuts.
A friend dropped by last night with two Quanta T3040-LY3 and wanted to get them configured. I fired up the Byrd Super Lab, and with some cat6 cables I had laying around, I created an eight port MLAG connection between the two Quanta switches. Then I set up port channels for many of the 48 ports and then used LACP on the Linux side to create redundant paths for my test network.
You should know there isn’t presently a lot of Google search results outside of retail establishments for Quanta hardware. So hopefully this post will be a good starting point for many people. I think you’ll find that the Quanta CLI is very similar to Cisco IOS. That said, there are some annoying differences. There is no enable mode, even though the manual refers to it and lets you set in and enable password. Also some commands cannot be undone by putting the word “no” in front of them like you can with Cisco. As well, it seems impossible to disable router rip or router IPv6. Hopefully someone from quanta can weigh in here and let us know what’s up.
Yes, I said MLAG. Some people call it MCLAG, but basically you contect two switch together with dedicated ports. Since they’re not Cisco switches, there’s no magical stacking cable included with these Quanta Servers.
