I got a great deal on a used 7050 that I am trying get working with my setup. I have followed the initial setup guide to get the management interface working. I have two servers both with ESXI 6.5, a Connect X3 and uplinked to a vswitch on each server and both nics connected to the switch (port 2 and 3). Both VMs are CentOS and both configured on the same subnet 192.168.1.2/24 and 1.3/24. I am trying to get just basic switching working, no vlans etc... just getting the servers to talk to each other. I cannot ping either of them, although I know both nics work fine because I can direct connect the a QSFP cable to each server and get them talking.

Show interface status shows connectivity (port 2 and 3).

Port Name Status Vlan Duplex Speed Type Flags
Et1/1 connected routed full 10G 10GBASE-CR
Et2/1 connected routed full 40G 40GBASE-CR4
Et3/1 connected routed full 40G 40GBASE-CR4

A show running config shows the following

I am sure I am doing something stupid so go easy on me. This is my first time using an enterprise grade switch, my others are all UBNT.

I'm in the process of ordering the same switch so I dont have "hands on" experience with them yet but believe that you need to configure the ports as trunk links. Even though you're not tagging vlans your traffic will pass through the trunks native vlan 1. The ports are currently configured as routed interfaces.

BTW I noticed you changed the environment fan-speed override to 40. How are the noise levels now compared to the out of box fan speed?

I have a bit to learn, that was the issue.

Yeah, I think it sounds fine. I had an LB6M and that was a screamer compared to this thing at 40. At 100% it is probably comparable to the 6m. I could probably go lower then 40%, the temps seem fine. Compared to out the box it is probably 1/2 as quiet or so. It takes some of the whine out of the fans.

Good to hear. Once you can start benchmarking hopefully the temps stay within a comfortable range. I'm hoping this switch works out. Only thing worse than a screaming switch is a screaming wife! Lol.

great deal. pretty much the latest firmware. where do you get the switch or that software from?
