SDN Hardware

Im Labor stehen 2 SDN Switche zur Benutzung bereit:

• 48 Port - 1 Gbit/s
• 4 Port SFP+ - 10 Gbit/s
• 2 Port QSFP+ (20 Gbit/s - Stacking Ports)

• 48 Port SFP28 10 - 25 Gbit/s
• 6 Port QSFP28 - 100 Gbit/s

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

mit Console-Port verbinden, reboot Switch, U-boot abbrechen durch Tastendruck

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 

run onie-rescue
onie-nos-install http://repo.bisdn.de/pub/onie/agema-ag5648/onie-bisdn-agema-ag5648-v4.6.1.bin

Auf den Switches ist Baseboxd installiert.

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

Optische Ports bieten keine oder nur eingeschränkte Auto-Negotiation. Disable auto-negotiation und Portspeed auf 10Gbit/s:

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

Use the following command to print the current port configuration:

sudo client_drivshell ports

Use the parameter ps to list all ports or ps <port number> to list one specific port.

sudo client_drivshell ps 1

IP Interface Konfiguration:

ip link show
sudo ip link set port48 up
sudo ip address add 10.0.0.1 dev port48
ethtool port48

SDD - Write Cache disable: I created a hdparm.service file in /etc/systemd/system/multi-user.target.wants with the following settings:

[Unit]
Description=hdparm write cache disable

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

[Install]
WantedBy=multi-user.target

In /etc/systemd/network eine Datei anlegen 70-enp.network:

[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
