SFP/QSFP Compatibility Matrix

Setup

• 2 Laptops configured with an IP in an chosen Subnet.
• 2 Switches connected using the same SFP on both sides.
• One Laptop connected to the first switch, and the other one connected to the other switch.
• Connect to serial switch console, log in with cumulus/CumulusLinux!

Edgecore

Additionally needed steps for Edgecore (Rolled back using sudo mv /etc/network/interfaces.bak /etc/network/interfaces and sudo ifreload --all):

• cp /etc/network/interfaces /etc/network/interfaces.bak
• sudo nano etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).


source /etc/network/interfaces.d/*.intf

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

auto vlan
iface vlan
     bridge-vlan-aware yes
     bridge-ports glob swp1-54
     bridge-stp on

• sudo ifreload --all

Quanta

• The default speed of the SFP ports is 10000
• For 1G modules, you have to set it to 1000
• Use the following commands:
  • net add interface swp49 link speed 1000
  • net commit
• These commands will edit the /etc/network/interfaces file and apply the config.
