Sweetcomb
========================
## Introduction
Sweetcomb is a management agent that runs on the same host as a VPP instance,
and exposes yang models via NETCONF or RESTCONF or gRPC to allow the management of that VPP instance from out-of-box.
For more information on VPP and its features please visit the
[Sweetcomb website](https://wiki.fd.io/view/Sweetcomb)
## Changes
Details of the changes leading up to this version of Sweetcomb can be found under
@ref release notes.
## Directory layout
| Directory name | Description |
| ---------------------- | ------------------------------------------- |
| build-root | Build output directory |
| @ref src/plugins | Sweetcomb bundled plugins directory |
| @ref src/scvpp | Sweetcomb to VPP communication |
## Getting started
Make sure you have added FD.io repository using https://packagecloud.io/fdio/release/
installation script.
You should have a sight on the release package, the package name may be different depending on the distribution.
(ex: vpp-plugins.deb for VPP 19.01 and vpp-plugin-core.deb and vpp-plugin-dpdk.deb in 19.04)
Firstly, please follow below steps to install dependencies and build code:
```
cd $/sweetcomb/
make install-dep
make install-dep-extra
make install-vpp
make build-scvpp
make build-plugins
```
Next, install YANG models in sysrepo:
```
make install-models
```
Then, please start each daemon one by one:
```
start vpp (for example on Ubuntu: systemctl start vpp)
sysrepod
sysrepo-plugind
netopeer2-server
netopeer2-cli
```
Now you can utilize Sweetcomb.
## Manual Test
For example, if you want to configure ipv4 address on HW interface TenGigabitEthernet5/0/0,
You can follow below steps to verify if Sweetcomb is working well.
Firstly, set interface up:
`vppctl set interface state TenGigabitEthernet5/0/0 up`
Then, starting netopeer2-cli on any host:
netopeer2-cli
```
> connect --host <ip address running Sweetcomb> --login <user>
> edit-config --target running --config
```
```
<interfaces xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces">
<interface>
<name>TenGigabitEthernet5/0/0</name>
<description>eth0</description>
<type xmlns:ianaift="urn:ietf:params:xml:ns:yang:iana-if-type">ianaift:ethernetCsmacd</type>
<ipv4 xmlns="urn:ietf:params:xml:ns:yang:ietf-ip">
<enabled>true</enabled>
<mtu>1514</mtu>
<address>
<ip>192.168.50.72</ip>
<prefix-length>24</prefix-length>
</address>
</ipv4>
<enabled>true</enabled>
</interface>
</interfaces>
```
Finally, check the configuration result.
`vppctl show interface address`
If you configure above successfully, you will get ip address set up on interface TenGigabitEthernet5/0/0.
