====== SDN Hardware ======

Im Labor stehen 2 SDN Switche zur Benutzung bereit:

=== EdgeCore AS4610-54T ===
  * 48 Port - 1 Gbit/s 
  * 4 Port SFP+ - 10 Gbit/s
  * 2 Port QSFP+ (20 Gbit/s - Stacking Ports) 

=== Delta AG5648V1 ===
  * 48 Port SFP28 10 - 25 Gbit/s
  * 6 Port QSFP28 - 100 Gbit/s 

==== BISDN Installation/Upgrade ====

  * Anleitung: https://docs.bisdn.de/getting_started/install_bisdn_linux.html
  * BISDN-Images: http://repo.bisdn.de/pub/onie/

=== Installation via USB: ===
mit Console-Port verbinden, reboot Switch, U-boot abbrechen durch Tastendruck
<code bash>
run onie-rescue
blkid # Info über angeschlossene Speichermedien
mkdir /tmpInstaller
mount -t vfat /dev/sdb1 /tempInstaller
onie-nos-install /tempInstaller/onie-bisdn-accton-as4610-v4.6.1.bin 
</code>

=== Installation via Netz: ===
<code bash>
run onie-rescue
onie-nos-install http://repo.bisdn.de/pub/onie/agema-ag5648/onie-bisdn-agema-ag5648-v4.6.1.bin
</code>

==== BISDN Konfiguration ====
Auf den Switches ist Baseboxd installiert.

<code bash>
#start cu: terminates via ~.
#Console-Port: 115.000 Baud
sudo cu -l /dev/tty.usbserial-FTF8T2BZ -s 115200
</code>

   login: basebox
   password: b-isdn

Optische Ports bieten keine oder nur eingeschränkte Auto-Negotiation.
Disable auto-negotiation und Portspeed auf 10Gbit/s:
<code bash>
sudo client_drivshell port xe0 AN=off sp=10000 #port 49-50 (xe0-xe3)
sudo client_drivshell port 50 Enable=false
sudo client_drivshell port 50 Enable=true
</code>
Use the following command to print the current port configuration:
<code bash>
sudo client_drivshell ports
</code>

Use the parameter ''ps'' to list all ports or ''ps <port number>'' to list one specific port.
<code bash>
sudo client_drivshell ps 1
</code>

**IP Interface Konfiguration:**

<code bash>
ip link show
sudo ip link set port48 up
sudo ip address add 10.0.0.1 dev port48
ethtool port48
</code>

**SDD - Write Cache disable:**
I created a ''hdparm.service'' file in ''/etc/systemd/system/multi-user.target.wants'' with the following settings:
<code>
[Unit]
Description=hdparm write cache disable

[Service]
Type=oneshot
ExecStart=/sbin/hdparm -W0 /dev/sda

[Install]
WantedBy=multi-user.target
</code>
==== Management Interface konfigurieren:  ====
In ''/etc/systemd/network'' eine Datei anlegen ''70-enp.network'':
<code bash>
[Match]
# You can also use wildcards. Maybe you want enable dhcp on an all eth* NICs
Name=enp*
[Network]
#DHCP=v4
# static IP
Address=172.16.1.8/24
Gateway=172.16.1.1
DNS=141.45.2.100 141.45.3.100
</code>
