The document is *PRE PRODUCTION*.

h2. Server configuration
8
9
* All servers are supposed to have eth0 and eth1
10
** Both cards are fiber
11
** Both cards will be bonded
12
* The ROM/BIOS of servers should be configured for netbooting
13
14
h2. Switch configuration
15
16
* Switches are MLAG bonded over two switches
17
* Servers are thus redundantly connected to two switches
18
* To support netbooting easily, we setup a "native vlan"
19
** Aka which vlan to use if there is untagged traffic

Sample configuration from place6 (2021-02-07):

23
<pre>
24
interface Port-Channel1
25
   switchport trunk native vlan 10
26
   switchport mode trunk
27
   port-channel lacp fallback static
28
   port-channel lacp fallback timeout 20
29
   mlag 1

</pre>

h2. IP configuration
33
34
* As many PXE roms still don't properly support IPv6, we use IPv4 netbooting
35
** This might be changed in the future, when we can replace all ROMs with ipxe
