No interfaces showing in AWS Ubuntu 20.04

[Marc Walker]

Hello everyone,

Is there a newer version of how to install the flexiwan router in AWS? I cant seem to get the FlexiUI to see my network devices.

I am following the manual process - https://docs.flexiwan.com/guides/manual.html

In vmware this works fine, just not in AWS?

network:
    ethernets:
        eth0:
            dhcp4: true
            dhcp4-overrides:
                route-metric: 100
            dhcp6: false
            match:
                macaddress: 06:d3:e8:3c:c9:76
            set-name: eth0
        eth1:
            dhcp4: true
            dhcp4-overrides:
                route-metric: 200
            dhcp6: false
            match:
                macaddress: 06:93:ea:24:8e:f0
            set-name: eth1
    version: 2

Hi,

Which instance type are you using?
Some EC2 instances do not support DPDK which is a requirement by flexiEdge.
Best practice to use enhanced networking -  Elastic Network Adapter (ENA).

Can you provide the output of the command ec2metadata

Hi Sassy,

Thank you for your response.

Instance type is t2.medium with an Ubuntu 20.04 image that says it supports ENA.

Output below as requested:

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking-ena.html

Network  interface driver

the following command to verify that the ena module is being used on a particular interface, substituting the interface name that you want to check. If you are using a single interface (default), it this is eth0. If the operating system supports predictable network names, this could be a name like ens5.

In the following example, the ena module is not loaded, because the listed driver is vif.

[ec2-user ~]$ ethtool -i eth0
driver: vif
version:
firmware-version:
bus-info: vif-0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

In this example, the ena module is loaded and at the minimum recommended version. This instance has enhanced networking properly configured.

[ec2-user ~]$ ethtool -i eth0
driver: ena
version: 1.5.0g
firmware-version:
expansion-rom-version:
bus-info: 0000:00:05.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: no

Hi Sassy,

I think its the VM instance type as you originally suggested:

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html#current-gen-instances

I have it working on an m5.large, so will play around with the smaller ones and see if I can get a 2core, 4gb RAM version working.

Many thanks for your help! :)
