Appendix B: Known limitations

The SR-SIM has the following limitations (this is not an exhaustive list):

  • The SR-SIM is designed to replicate control and management plane operations, and port throughput is limited to 1000 pps/port as a result. However, overall throughput is dependent on the resources allocated.
  • The control-plane performance is restricted.
  • The filesystem on the SR-SIM is case-sensitive.
  • In-Service software upgrade (ISSU) is not supported.

Appendix C: Example Kubernetes configuration using k3s on Ubuntu 24.04

Prerequisites

Ensure all host interfaces are configured with an MTU of 9000 before installation.

Install k3s

Replace <my_secret_token> in the following command with a private key specific to your installation.

curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="server" sh -s - --agent-token <my_secret_token> --write-kubeconfig-mode "0666"

The --write-kubeconfig-mode "0666" flag is optional, allowing non-root users to issue kubectl deployment commands.

Ensuring the cni0 interface is set to an increased MTU

Issue the following command.

ifconfig cni0

The output should look similar to this.

cni0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 8950
        inet 10.42.0.1  netmask 255.255.255.0  broadcast 10.42.0.255
        inet6 fe80::181f:44ff:fe3f:484d  prefixlen 64  scopeid 0x20<link>
        ether 1a:1f:44:3f:48:4d  txqueuelen 1000  (Ethernet)
        RX packets 89118  bytes 687051420 (687.0 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 104066  bytes 697894863 (697.8 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Ensuring the flannel.1 interface is set to an increased MTU

Issue the following command.

ifconfig flannel.1

The output should look similar to this.

flannel.1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 8950
        inet 10.42.0.0  netmask 255.255.255.255  broadcast 0.0.0.0
        inet6 fe80::7415:7cff:fe68:a94e  prefixlen 64  scopeid 0x20<link>
        ether 76:15:7c:68:a9:4e  txqueuelen 0  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 7 overruns 0  carrier 0  collisions 0

If the MTU on the flannel.1 interface is still set to a lower MTU, you can edit the /etc/systemd/system/k3s.service file to ensure the system is started based on the cni0 interface (which has a larger MTU) replacing this line:

ExecStart=/usr/local/bin/k3s \
    server \
        '--agent-token' \
        '<my_secret_token>' \
        '--write-kubeconfig-mode' \
        '0666' \

With this:

ExecStart=/usr/local/bin/k3s \
    server \
        '--agent-token' \
        '<my_secret_token>' \
        '--write-kubeconfig-mode' \
        '0666' \
        '--flannel-iface' \
        'cni0' \

Now restart the k3s daemon.

sudo systemctl daemon-reload
sudo systemctl restart k3s

Ensuring transmit checksum offloading is disabled for the cni0 interface

Issue the following command.

sudo ethtool -K cni0 tx-checksum-ip-generic off

Create aliases for kuebctl

Create the following aliases in your shell. If you are using bash, add the following lines to the ~/.bash_aliases file.

alias kubectl="k3s kubectl"
alias k="kubectl"

Then reread the file by issuing the following command.

source ~/.bash_aliases

kubectl apply -k .

Install the Multus CNI

Install the Multus CNI, which provides the ability to add multiple interfaces to a container.

Create the following file in a different directory from the container-registry directory.

multus-k3s.yml

apiVersion: helm.cattle.io/v1
kind: HelmChart
metadata:
  name: multus
  namespace: kube-system
spec:
  repo: https://rke2-charts.rancher.io
  chart: rke2-multus
  targetNamespace: kube-system
  valuesContent: |-
    config:
      fullnameOverride: multus
      cni_conf:
        confDir: /var/lib/rancher/k3s/agent/etc/cni/net.d
        binDir: /var/lib/rancher/k3s/data/cni/
        kubeconfig: /var/lib/rancher/k3s/agent/etc/cni/net.d/multus.d/multus.kubeconfig

Deploy this manifest to the Kubernetes cluster using the following command.

kubectl apply -f multus-k3s.yml

If it deploys correctly, you should see output similar to the following when the kubectl get all -n kube-system --show-labels -l app=rke2-multus command is issued.
