## Server Hardware
* Dell PowerEdge R240 1U * 2
* Laptop * 1
## Hardware Info
```bash
$lshw -class network -businfo //check PCI
```
## VPP
```bash
$vppctl
set int state ($device_name) up
set int ip address ($device_name) ($ip)/($mask)
set interface ip table <interface> <table-id>
show int
show int address
show hard-ware interface
```
* SetUp sample code
```python=
from framework import VppTestCase
class PGinterface(VppTestCase):
def setUpClass(cls):
super(PGinterface, cls).setUpClass()
def tearDownClass(cls):
super(PGinterface, cls).tearDownClass()
def setUp(self):
super(PGinterface, self).setUp()
if __name__ == '__main__':
test = PGinterface()
test.setUpClass()
test.setUp()
```
* Create PGinterface sample code
```python=
class PGinterface(VppTestCase):
...
def setUp(self):
super(PGinterface, self).setUp()
# create 4 pg interfaces
self.create_pg_interfaces(range(2))
# setup interfaces
# assign them different tables
table_id = 0
self.tables = []
for i in self.pg_interfaces:
i.admin_up()
if table_id != 0:
tbl = VppIpTable(self, table_id)
tbl.add_vpp_config()
self.tables.append(tbl)
tbl = VppIpTable(self, table_id, is_ip6=1)
tbl.add_vpp_config()
self.tables.append(tbl)
i.set_table_ip4(table_id)
i.set_table_ip6(table_id)
i.config_ip4()
i.config_ip6()
table_id += 1
```
* sample
```cpp
```
VPP沒提供的功能就要用DPDK寫出plugins
## DPDK
```bash
$cd /home/$(whoami)/dpdk-($version_dir)/($dpdk-build)
$modprobe uio
$insmod kmod/igb_uio.ko
$cat /proc/meminfo | grep Huge
```
## iperf3
```bash
$iperf3 -s //server
$iperf3 -c ($ip) //client (default TCP)
```
## tmux
```bash
# 新增
$ tmux
# OR
$ tmux new -s <your_session_name>
# session 列表
$ tmux ls
# 重新連線 session
$ tmux a -t 0
# OR
$ tmux a -t <session_name>
# 刪除 session
$ tmux kill-session -t 0
# OR
$ tmux kill-session -t <session_name>
# OR
$ tmux kill-session -a # 全部
# 刪除 tmux server
$ tmux kill-server
# 重新命名 session
$ tmux rename-session -t 0 <new_session_name>
# 快捷鍵/視窗管理
# C-b ? Help
# C-b c 新增視窗
# C-b， 視窗命名
# C-b w 視窗列表
# C-b f 尋找視窗
# C-b & 刪除視窗
# C-b % 垂直分割區塊
# C-b “ 水平分割區塊
# C-b <方向鍵>
# C-b p 上一個視窗
# C-b n 下一個視窗
# C-b <number> 依照編號直接切換（編號顯示於狀態列）
# C-b d 離開 session
# C-b x 關閉 Pane
# C-d 關閉 Pane
# C-b z 讓一個 Pane 變成全螢幕，在輸入一次則回到剛剛的尺寸
```
## Experiment
```bash
$iperf3 -s //server
$iperf3 -u -c 192.168.2.200 -l 64 -b 0M -t 300 //client
VPP Forwarding 22.5 MB/s Lost 51 % (UDP)
```
```bash
$iperf3 -s //server
$iperf3 -c 192.168.2.200 //client
VPP Forwarding 81.25 MB/s (TCP)
```
