Acceleration

In this command tree, all hardware acceleration options will be handled. At the moment only Intel® QAT is supported

Intel® QAT

show system acceleration qat

use this command to check if there is an Intel® QAT supported Processor in your system.

vyos@vyos:~$ show system acceleration qat
01:00.0 Co-processor [0b40]: Intel Corporation Atom Processor C3000 Series QuickAssist Technology [8086:19e2] (rev 11)

if there is non device the command will show `No QAT device found`

set system acceleration qat

if there is a supported device, enable Intel® QAT

show system acceleration qat status

Check if the Intel® QAT device is up and ready to do the job.

vyos@vyos:~$ show system acceleration qat status
Checking status of all devices.
There is 1 QAT acceleration device(s) in the system:
qat_dev0 - type: c3xxx,  inst_id: 0,  node_id: 0,  bsf: 0000:01:00.0,  #accel: 3 #engines: 6 state: up

Operation Mode

show system acceleration qat device <device> config

Show the full config uploaded to the QAT device.

show system acceleration qat device <device> flows

Get an overview over the encryption counters.

show system acceleration qat interrupts

Show binded qat device interrupts to certain core.

Example

Let’s build a simple VPN between 2 Intel® QAT ready devices.

Side A:

set interfaces vti vti1 address '192.168.1.2/24'
set vpn ipsec esp-group MyESPGroup proposal 1 encryption 'aes256'
set vpn ipsec esp-group MyESPGroup proposal 1 hash 'sha256'
set vpn ipsec ike-group MyIKEGroup proposal 1 dh-group '14'
set vpn ipsec ike-group MyIKEGroup proposal 1 encryption 'aes256'
set vpn ipsec ike-group MyIKEGroup proposal 1 hash 'sha256'
set vpn ipsec interface 'eth0'
set vpn ipsec site-to-site peer 10.10.10.1 authentication mode 'pre-shared-secret'
set vpn ipsec site-to-site peer 10.10.10.1 authentication pre-shared-secret 'Qwerty123'
set vpn ipsec site-to-site peer 10.10.10.1 connection-type 'initiate'
set vpn ipsec site-to-site peer 10.10.10.1 default-esp-group 'MyESPGroup'
set vpn ipsec site-to-site peer 10.10.10.1 ike-group 'MyIKEGroup'
set vpn ipsec site-to-site peer 10.10.10.1 local-address '10.10.10.2'
set vpn ipsec site-to-site peer 10.10.10.1 vti bind 'vti1'

Side B:

set interfaces vti vti1 address '192.168.1.1/24'
set vpn ipsec esp-group MyESPGroup proposal 1 encryption 'aes256'
set vpn ipsec esp-group MyESPGroup proposal 1 hash 'sha256'
set vpn ipsec ike-group MyIKEGroup proposal 1 dh-group '14'
set vpn ipsec ike-group MyIKEGroup proposal 1 encryption 'aes256'
set vpn ipsec ike-group MyIKEGroup proposal 1 hash 'sha256'
set vpn ipsec interface 'eth0'
set vpn ipsec site-to-site peer 10.10.10.2 authentication mode 'pre-shared-secret'
set vpn ipsec site-to-site peer 10.10.10.2 authentication pre-shared-secret 'Qwerty123'
set vpn ipsec site-to-site peer 10.10.10.2 connection-type 'initiate'
set vpn ipsec site-to-site peer 10.10.10.2 default-esp-group 'MyESPGroup'
set vpn ipsec site-to-site peer 10.10.10.2 ike-group 'MyIKEGroup'
set vpn ipsec site-to-site peer 10.10.10.2 local-address '10.10.10.1'
set vpn ipsec site-to-site peer 10.10.10.2 vti bind 'vti1'

a bandwidth test over the VPN got these results:

with set system acceleration qat on both systems the bandwidth increases.
