## Additional parameters:
##
## To set the number of binary API trace records in the circular buffer, configure nitems
##
## nitems <nnn>
##
## To save the api message table decode tables, configure a filename. Results in /tmp/<filename>
## Very handy for understanding api message changes between versions, identifying missing
## plugins, and so forth.

## In the VPP there is one main thread and optionally the user can create worker(s)
## The main thread and worker thread(s) can be pinned to CPU core(s) manually or automatically
## Manual pinning of thread(s) to CPU core(s)
## Set logical CPU core where main thread runs, if main core is not set
## VPP will use core 1 if available
# main-core 1
## Set logical CPU core(s) where worker threads are running
# corelist-workers 2-3,18-19
## Automatic pinning of thread(s) to CPU core(s)
## Sets number of CPU core(s) to be skipped (1 ... N-1)
## Skipped CPU core(s) are not used for pinning main thread and working thread(s).
## The main thread is automatically pinned to the first available CPU core and worker(s)
## are pinned to next free CPU core(s) after core assigned to main thread
# skip-cores 4
## Specify a number of workers to be created
## Workers are pinned to N consecutive CPU cores while skipping "skip-cores" CPU core(s)
## and main thread's CPU core
# workers 2
## Set scheduling policy and priority of main and worker threads
## Scheduling policy options are: other (SCHED_OTHER), batch (SCHED_BATCH)
## idle (SCHED_IDLE), fifo (SCHED_FIFO), rr (SCHED_RR)
# scheduler-policy fifo
## Scheduling priority is used only for "real-time policies (fifo and rr),
## and has to be in the range of priorities supported for a particular policy
# scheduler-priority 50

## Default is 1
# num-rx-queues 3
## Number of transmit queues, Default is equal
## to number of worker threads or 1 if no workers treads
# num-tx-queues 3
## Number of descriptors in transmit and receive rings

## Default is 1024 for both rx and tx
# num-rx-desc 512

## VLAN strip offload mode for interface
## Default is off

## Whitelist specific interface by specifying PCI address
# dev 0000:02:00.0
## Blacklist specific device type by specifying PCI vendor:device
## Whitelist entries take precedence
# blacklist 8086:10fb
## Set interface name
# dev 0000:02:00.1 {

## addition specify custom parameters for this interface

# vdev eth_bond1,mode=1,slave=0000:02:00.1,slave=0000:03:00.1
## Change UIO driver used by VPP, Options are: igb_uio, vfio-pci,
## uio_pci_generic or auto (default)
# uio-driver vfio-pci
## Disable multi-segment buffers, improves performance but
## disables Jumbo MTU support
# no-multi-seg
## Increase number of buffers allocated, needed only in scenarios with
## large number of interfaces and worker threads. Value is per CPU socket.
## Default is 16384
# num-mbufs 128000
## Change hugepages allocation per-socket, needed only if there is need for
## larger number of mbufs. Default is 256M on each detected CPU socket
# socket-mem 2048,2048
## Disables UDP / TCP TX checksum offload. Typically needed for use
## faster vector PMDs (together with no-multi-seg)
# no-tx-checksum-offload

# plugins {
## Adjusting the plugin path depending on where the VPP plugins are
