I bet that it'll be related to 4/x interfaces.
I'm not sure how they tie to VLANs, but I think that they do...

Hi all. I'm wondering if I could get some assistance. I admittedly have no idea what I'm doing, but I'm having fun doing it.
I picked up an LB4M a year ago and have been using it as an unmanaged switch. Over the holidays this year, I had a few weeks off so decided to try my hand at 10Gbe. I picked up some PCIe cards, transceivers, and some fiber cable. I connected the card, plugged the transceivers in, and finally the fiber. I then looked at the uplink status lights on the switch. Unlit. I reset the switch to default settings. Nothing.
Am I missing something? I've made sure that I matched my fiber to to the transceivers (MM).

- Cards: Dell Y40PH (Broadcom 57810S). One in Tower NAS, one in R720
- SPF+: Dell Y3KJN SR 850 NM.
- Cable: LC/LC Multimode OM3 50/125
- I've enabled bnx2x on both Debian hosts (Proxmox). Interfaces enp65s0f0 & enp65s0f1 show up on both machines. I created Linux Bridge interfaces within Proxmox using these and assigned them, one by one, to a Windows VM for testing. Neither worked.
- Tower NAS: 192.168.3.1 255.255.255.0
- R720: 192.168.3.2 255.255.255.0
Has anyone have the management interface (on a VLAN, not on the service port) half-disappear? I can see the switch with ping and nmap, and 23/80 show filtered. ARP tables on PC and adjacent switch also show it in the right place - but neither a web browser nor telnet will connect. Just when I wanted to throw another VLAN on it too.
My config is not a standard one, but maybe you can extrapolate what you need:
network protocol none
network parms 10.16.10.14 255.255.255.0 10.16.10.1
vlan database
vlan 666,1601,1610
vlan name 1610 "Network Management"
network mgmt_vlan 1610
ip ssh server enable
ip ssh protocol 2
no ip telnet server enable
configure
no ip domain lookup
ip domain name "network.com"
username "admin" password <long_hash_string> level 15 encrypted
aaa authentication login "RADIUS" radius local
aaa session-id unique
radius server host auth "10.16.10.250" name "RADIUS1"
radius server key auth "10.16.10.250" encrypted <long_hash_string>

Funny man. No that's the point - it's been a static config for 2 years or so, at least, and now I can't get to it to manage it at all. Suppose I'll have to scare up the USB to serial adapter or something, though it's been years since I needed it …
I couldn't figure out how to run the switch in an unmanaged way. I know very little about networking and I want to run this switch unmanaged style but I can't figure out how to get it working at all
Just set the login password to what you want. Take note of it somewhere. All the ports are VLAN 1 by default which is the automatic default of most if not all switches and leave the rest be. It will work without doing anything else to it.
I tried that but I could not get my switch to grab an IP when in dhcp mode (which i presume you need for internet access for ports of the switch correct?). For some reason both of the lights on the ethernet ports when I try to plug into the switch flash orange always. I have tried the router firmware with web interface and the switch firmware with web interface (the less buggy one, like 1.2.7... or something).
The console is the most stable and safest way to make changes to the switch, at least to my understanding.
If you're unable to determine the IP of the switch then it may be set to DHCP on the management port.
The management port is another switch port dedicated to only switch management. Try plugging the management port directly into one of the other 48 ports and see if it pulls a address.
If not you may need to grab a serial console cable and use the console port to make changes.
If you're able to access the web interface but not the console then chances are either SSH, Telnet or both services have been disabled. Make sure one, the other or both are enabled. I prefer SSH as it is more secure than telnet. The web address will be the same address as the console address
Applications like Putty will allow you to access the console of the switch either via Telnet, SSH or serial.
Hopefully that all makes sense.

So did you get it to work in an unmanaged way?
If not, run these 2 commands:
show port all
show vlan port all
