pods

Pod Configuration

CalicoVPP exposes three types of interaces

• tuntap - regular linux netdevs
• memif - performance oriented packet interaces
• vcl - performance oriented host stack (TCP, UDP, TLS in VPP)

Configuration

The pod interface sizing can be confiugred with annotations in the pod manifest.

apiVersion: v1
kind: Pod
metadata:
  name: samplepod
  annotations:
    cni.projectcalico.org/vppInterfacesSpec: |-
    {
      "eth0": {
          "rx": 1,
          "tx": 1,
          "rxqsz": 1024,
          "txqsz": 1024,
          "rxMode": "polling",
          "isl3": true
      }
    }

• tx and rx set the number of queues the interface receives in VPP
• rxqsz and txqsz set the number of buffers the interface receives in VPP
• rxMode sets the way VPP reads from this interface (polling adaptive or interrupt)
• isL3 sets the interface mode L3 for tun (default) or L2 for tap
