This example assumes you have exported the access token to the variable $TOKEN.

Retrieve the system-config template.
The template of a configuration element is a data structure containing all required sub-elements and supported attributes with their default values, along with any specified optional sub-elements.
```
curl -X GET -o response.xml \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://${SBCIP}/rest/v1.1/configuration/elementTypes/template?elementType=system-config"
```
The response is saved to the file response.xml.
Copy the content between the opening and closing <configElement> tags to a new file called system-config.xml.
If you are on a Linux system with xmllint installed, you may optionally format the XML before writing it to the file system.
```
sed -n '/<configElement>/,/<\/configElement>/p' response.xml | xmllint --format - > system-config.xml
```

Open the file and set the value of the hostname attribute to its desired value.

For example, if the hostname is example-sbc:

<?xml version="1.0"?>
<configElement>
  <elementType>system-config</elementType>
  <attribute>
    <name>hostname</name>
    <value>example-sbc</value>
  </attribute>
  ...
</configElement>

Acquire the configuration lock.

curl -X POST \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://${SBCIP}/rest/v1.1/configuration/lock"

Add the system-config configuration element.

curl -X POST \
    -d@system-config.xml \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://${SBCIP}/rest/v1.1/configuration/configElements"

If done editing the configuration, save, verify, and activate the configuration.

Release the configuration lock.

curl -X POST \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://${SBCIP}/rest/v1.1/configuration/unlock"
