So, I ended my last blog post with a wish hopefully someday I can get a real switch running Cumulus to play with  Well, as it turns out, that post was somewhat popular, and caught the attention of some folks at Cumulus Networks who kindly RTd my tweet publicizing the post thanks A day later, I was informed that Id been placed on the list for one of their demo switches that was making the rounds. And about a month later, I received an equipment travel case with a Delta Networks 6. Of course, it was quite similar to many other OEM sourced switches Ive seen from the likes of Dell, Super. Micro, et al on the front, 4. RJ 4. 5 Gig Ethernet ports, 4 SFP ports shared with RJ 4. Search the worlds information, including webpages, images, videos and more. Google has many special features to help you find exactly what youre looking for. RJ 4. 5 serial port and management Ethernet port in the rear, bays for two power supplies only one inserted into the unit, two rear exhaust fans, and two uplink modules again, only one came with the unit, a 2 x 1. Gb SFP module. But enough about the hardware the real meat lays inside I took it out of the road case, put it in my lab rack, and cabled it up to the assortment of switches I have there the DNI whitebox switch is on the shelf at the bottom I fired it up, and as it booted, I could already see that it was Linux At the end of the boot messages, I was greeted by a simple login prompt cumulus login I typed in root and then entered the default Cumulus Linux password, and there I was at a bash prompt. I tried a few commands I use to orient myself to a new Linux environment, and all worked just as youd expect them to on a Linux system rootcumulus uname a. Linux cumulus 3. 2. SMP Mon Nov 1. 8 1.

So I made up a lab plan, and then over the next few days, I tested out different scenarios involving grouping ports into VLANs in Linux, attaching ports to software bridges, which I named br vlanlt, implementing a trunk link to a Cisco switch involving using a interface, in this case swp. VLAN2 and VLAN3 traffic, which are named swp. LACP LAG in Linux, a bond between the CL switch, and a PC running Debian Linux which was the testbed for my prior blogpost. I also devoted a interface on the CL switch to my server running GNS3, which has a Cisco router lab, and I set up a OSPF area between the virtual Cisco routers in GNS3, and the CL switch using the open source routing suite known as Quagga which Cumulus ships with their OS. I then tied in a few laptops to test connectivity, and the end result looked like this As we can see, there are three VLANs VLAN1 green 1. VLAN2 blue 1. VLAN3 yellow 1. The bridges on the CL switch each had an IP applied to them in Linux, bridges can be addressed like interfaces the equivalent of a SVI in Cisco speak, which were 1. VLAN1, 1. 0. 1. 2. VLAN2, and 1. 0. 1. VLAN3, and were all advertised in OSPF. The routers in GNS3 had remote networks 2. OSPF. So the resulting configuration file for the switch ports which in Debian Linux, which Cumulus is based off of, lives in etcnetworkinterfaces was thus rootcumulus cat etcnetworkinterfaces. This file describes the network interfaces available on your system. For more information, see interfaces5. The loopback network interface. The management network interface. Link to Cisco SW1 3.

And from the Cisco router side The sharp eyed might notice that there is a default route static entry in the Quagga routing table to next hop to 1. R1 Cisco router in GNS3 that is not making it into the FIB and hence the Linux routing table. This is because the management ethernet port on the CL switch eth. DHCP, and this is overriding the static route I entered in Quagga. I had the pleasure of having support from Cumulus Networks for the term of my demo, and so I opened a ticket on this, and worked with an awesome guy named Barnaby, who is their main customer support tech. As it turns out, the management port can not interoperate with the fabric ports which is expected, and a good thing, but Linux doesnt know that, and is throwing the management port default route into the single Linux routing table which also is consumed by Quagga, showing up as a Kernel route there, which trumps the equivalent static route. For now, this is a drawback of the current implementation, but they do have VRF Lite on their roadmap, which should be available in a forthcoming release later this year, I was told. Everything else I labbed worked as expected, without problem. The best part of all for me is that Cumulus Linux is basically straight Debian Linux, with all the UNIX y goodness I have come to know and love. Due to the fact that the switches they support are based on Broadcom chipsets, and those chipset APIs are covered under NDA as well as the fact that basically to this point, Linux hasnt been envisioned by its creators as a switch OS, there are some closed source bits in the OS mainly, as I understand it, the switchd daemon that presents the fabric ports to the kernel as regular ethernet ports actually, tap devices are used, and thats why they are named swplt instead of  ethlt swp makes more sense in this case than the usual tap designator and that ties the Linux kernel networking structures down to the Broadcom chipset ASICs that do the actual packet forwarding.
