Complete these tasks to modify the boot parameters of the Session Border Controller (SBC).

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

Retrieve the current boot parameters.

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

The response is saved to the file response.xml.

Copy the content between the opening and closing <bootparams> tags to a new file called request.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 '/<bootparams>/,/<\/bootparams>/p' response.xml | xmllint --format - > request.xml
```

Open the file and change the text of the <value> elements to their desired values.

The request.xml file only needs to include the <bootparam> elements that you want to change.

To change only the IP address, netmask, and target name, write the following to the request.xml file:

<?xml version="1.0"?>
<bootparams>
  <bootparam>
    <name>IP Address</name>
    <value>10.0.0.2</value>
  </bootparam>
  <bootparam>
    <name>Netmask</name>
    <value>255.255.255.0</value>
  </bootparam>
  <bootparam>
    <name>Target Name</name>
    <value>PRIMARY</value>
  </bootparam>
</bootparams>

Acquire the configuration lock.

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

Update the boot parameters.

curl -X PUT -d@request.xml \
    --header "Accept: application/xml" \
    --header "Authorization: Bearer $TOKEN" \
    "https://${SBCIP}/rest/v1.1/configuration/bootparams"

Release the configuration lock.

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

Confirm the change was made with a GET request.

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

Reboot the machine.

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

The SBC reboots with the configured boot parameters.
