Network card can not be added

hardware
#1

If I want to add multiple network adapters (DHCP - Ethernet), the UCS always hangs on the second adapter. Example: Quad-port network card first port can be added immediately and without problems, second port UCS hangs with the message “Setting up IPvX network devices”.

Already tried several external (different) cards, the cards and NICs were all correctly detected and displayed during installation. When configuring the second NIC of a quadport card, however, it unfortunately never goes further.

Where can I find the UCS logs for the network settings I would have made?

Hi,

we prefer English language here, so I will reply in English. A short translation first of your issue:

Before checking if this is an issue of UCS I would try to configure the interfaces first manually.
Check the naming for your interfaces by

root@backup:/proc/net# networkctl 
WARNING: systemd-networkd is not running, output will be incomplete.

IDX LINK             TYPE               OPERATIONAL SETUP     
  1 lo               loopback           n/a         unmanaged 
  2 ens192           ether              n/a         unmanaged 
  3 docker0          ether              n/a         unmanaged 

3 links listed.

Now you can configure your additional interfaces manually ie with ifconfig:
ifconfig ens193 192.168.192.42 netmask 255.255.255.0 up

Once it is up you should be able to ping any host in this network which indicates the network card itself is running fine.

Once confirmed it is running fine you might configure your additional interfaces through ucs-variables as follows:

ucr set interfaces/eth1/address: 192.168.9.10
ucr set interfaces/eth1/broadcast: 192.168.9.255 
ucr set interfaces/eth1/ipv6/acceptRA: false
ucr set interfaces/eth1/netmask: 255.255.255.0
ucr set interfaces/eth1/network: 192.168.9.0
ucr set interfaces/eth1/start: true
ucr set interfaces/eth1/type: static

Check documentation if you prefer to set one of the interfaces to use a DHCP-assigned address.

I will reply soon, after trying with cmd configuration of the nics.

#4

Webinterface is stuck sometimes, any way to reset it? Tried service apache2 restart, but it did not work. Do I have to use any specific UCS-command for cmd to do this?

Hi,

both are two completely different things which are confusing for anyone reading here later. So I’d prefer to create a new thread for these issues.

To do it on command line you should better use PuTTy to connect to your server instead of using the console directly (BTW: virtual machine [which hypervisor?] or physical?)

Its a X11DPI-NT Supermicro Board physical Hardware. I will keep this updated If I have any news about the network cards.

#7

Hardware: Supermicro X11DPI-NT
CPU: Intel Xeon Silver 4110
RAM: ATP DDR4 2666 MHz ECC REG
Network Card (PCIe): Intel X710/X557-AT 10GBASE-T (Intel X710 T4)

The follow happens If I add OR delete network devices:

  • univention-mana (process) goes 100% CPU
  • webinterface is stuck
  • network cards are configured correctly (console via server direct access)

I end up in rebooting the server because I dont know how to fix webinterface via cli.

Edit1: It also happens on a Intel I350 T4. I guess it has nothing to do with specific card(s).
