    Mellanox SX6036 DHCP Relay Problems

    I have a couple VLANs and I wanted to set an upstream DHCP relay on them so I could point it to a DHCP server I'm hosting, but the switch is giving me an error if I try to enable it at all. This is said throughout when I just try to enable it or point it to a helper address at all, I can go...

    Mellanox SX6036 L3 VLAN woes

    I'm having issues routing from the switch to the router/ISP. I have 2 VLANs created to separate the Workstations and the Servers, and while Inter-VLAN routing is working, getting out of the switch and to the router is not working. I cannot create a routerport on this switch as it says the device...

    Mellanox ConnectX-3 Pro EN (MCX314A-BCCT)

    Not sure if these Pro versions are still a thing but pricing is going wild. If you take more than 10x seller accepts 15US$ :oops: Hope they are genuine. If I'm not mistaken, these can do 56Gbps on IB. Mellanox ConnectX-3 Pro EN Netzwerkkarte (MCX314A-BCCT) 7290107197144 | eBay

    Both ports on Mellanox ConnectX-3 FDR/EN have the same PCI function ID | HP 649282-B21

    Hi, I recently started to use the HP Mellanox QSFP+ cards (both 649282-B21 and 764285-B21) but I'm facing the issue that both ports on the NIC have the exact same PCI address (even the same function id). I wanted to use them for a VPP router but this does not work as DPDK can't handle this edge...

    Does a Mellanox SN2010 SFP28 port support 1GbE?

    Hello All, We are configuring our Mellanox SN2010 switches and need to configure one of the SFP28 ports for 1GbE to connect to the Internet circuit in our cabinet. I don't see on the Mellanox datasheet explicit support for 1GbE connection - only 10/25GbE. We purchased several of these...

    Hello, after long efforts, I upgraded my MELLANOX CONNECTX-2 MNPA19-XTR cards to firmware version 2.10.720. However, interestingly, iperf3 shows 6.55Gbits speed when copying files from my NAS Server (OpenMediaVAult 6.3 Debian 11) to my Windows 11 Client. However, when copying files from my...

    What would cause a command to be added/removed from a Mellanox switch config?

    I have an MSB7800 running 3.10.2102 code and it seems like the following config line at the end is being added and removed randomly. Does anyone know why this would happen? I have confirmation from the team no one is doing it manually and I am trying to get the configs into git for archive...

    Good morning, We've had an SSD on our sb7800 infiniband switch fail, have installed a new drive with a cloned image from one of our other identical switches. So far everything looks ok in the management interface, aside the Host ID. Though we do get 1003, 1006 errors when trying to modify...

    EXPIRED Mellanox MCP1600-E002 QSFP28 IB EDR (100Gb/s) 2M DAC used - $12 OBO Looks like it was discounted to $12 few days ago. Which is an attractive price for EDR DAC. From quick research MCP1600-Exxx should support 56G Ethernet and FDR 56Gbit/s IB both. Ordered 4 for myself.

    Mellanox ConnectX-3 Wake on LAN

    Hi, I'm using ConnectX-3's to implement 40Gbit networking throughout my home, and one of the important nodes is the HTPC. As you might imagine I think that it would be swell given the lack of HDMI-CEC on Nvidia to be able to boot up the PC without getting off the couch. The first step for that...

I have need for the even smaller profile single slot QSFP+ cards like the above, which I see on EBay, and I'd like to...

    Juniper LX4 optics & Mellanox CX3/SX6036 compatibility

    Quick question: Has anyone had any success with 40G LX4 transceivers in Mellanox CX3 cards and SX6036 switches (specifically Juniper QSFP+ 40G LX4 LC transceivers)? I'm about to run optics throughout the house, and MTP/MPO cables are so much more expensive than LC/LC cables for multiple runs...
