4. Configure supervisor to monitor macsecmgrd
5. Set macsec in the features list
6. Add config variable `INCLUDE_MACSEC`
7. Add macsec.service
**- How to verify it**
Change the `/etc/sonic/config_db.json` as follow
```
{
"PORT": {
"Ethernet0": {
...
"macsec": "test"
}
}
...
"MACSEC_PROFILE": {
"test": {
"priority": 64,
"cipher_suite": "GCM-AES-128",
"primary_cak": "0123456789ABCDEF0123456789ABCDEF",
"primary_ckn": "6162636465666768696A6B6C6D6E6F707172737475767778797A303132333435",
"policy": "security"
}
}
}
```
To execute `sudo config reload -y`, We should find the following new items were inserted in app_db of redis
```
