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

Retrieve the network-interface 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=network-interface"
```
The response is saved to the file response.xml.
Copy the content between the opening and closing <configElement> tags to two files called network-interface-s0p0.xml and network-interface-s0p1.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 - > network-interface-s0p0.xml
```
```
sed -n '/<configElement>/,/<\/configElement>/p' response.xml | xmllint --format - > network-interface-s0p1.xml
```

Retreive the configuration element metadata to discover the range of values for each attribute.

curl -X GET -o metadata.xml \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://${SBCIP}/rest/v1.1/configuration/elementTypes/metadata?elementType=network-interface"

Open both XML files and set the attributes to their desired values.

In HA environments, provide values for at least the following parameters.

Table - Parameters

Parameter	Description
`name`	Enter the name of the previously configured physical interface. For example, `s0p0` or `s0p1`.
`ip-address`	Set the IP address of this network interface.
`pri-utility-addr`	(HA environment) Enter the utility IP address for the primary HA peer.
`sec-utility-addr`	(HA environment) Enter the utility IP address for the secondary HA peer.
`netmask`	Set the netmask of this network interface.
`gateway`	Set the gateway that this network interface uses to communicate with the next hop.

Note:

For additional parameters, see the ACLI Configuration Guide.

The following example shows the full contents of the network-interface-s0p0.xml file.

<?xml version="1.0"?>
<configElement>
  <elementType>network-interface</elementType>
  <attribute>
    <name>name</name>
    <value>s0p0</value>

  </attribute>
  <attribute>
    <name>gateway</name>
    <value>192.168.1.1</value>
  </attribute>
</configElement>

Note:

Missing parameters assume the default values shown in the template.

Acquire the configuration lock.

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

Add both network-interface configurations to the SBC.

curl -X POST \
    -d@network-interface-s0p0.xml \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://${SBCIP}/rest/v1.1/configuration/configElements"

curl -X POST \
    -d@network-interface-s0p1.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"
