Radius server customization

In Config → Networking → Radius we will find a field available for setting additional attributes.

Some attributes are configured by default, such as Framed-IP, Framed-Route and Auth-Type.

Variables

We can use a lot of variables from within Splynx

Tariff

Most of these values can be changed on the configuration of Tariff plans within Splynx

FUP rule

These values are empty if no FUP rule is applied

Variable	Value
{{ rule_name }}	Name of FUP rule applied 'EMPTY' if CAP rule applied
{{ rule.percent }}	Speed decrease percent

Additional attributes

There are also 4 arrays of additional fields:

1. {{ customer_attributes }} - additional attributes of the customer.
2. {{ service_attributes }} - additional attributes of the internet service.
3. {{ tariff_attributes }} - additional attributes of the internet plan.
4. {{ card_attributes }} - additional attributes of the prepaid voucher.

These values can be utilized in the following format:

{{ array_name.field_name }}

Additional fields have configuration fields available for the name and title of the additional within Splynx. We use the name field and not the title field.

For example, we can create an additional field for a customer called 'my_field'. The format of the values for doing this would be as follows:

{{ customer_attributes.my_field }}

Variables usage

We use Twig engine within Splynx. Therefore, all it's capabilities are available for your use.

• Basic mathematical operations (+ - * /) Example: Mikrotik-Rate-Limit = {{ tx_rate_limit / 1000 }} Result: Mikrotik-Rate-Limit = 10 (assume that tx_rate_limit=10000)

• Attributes combination Example: Mikrotik-Rate-Limit = {{ rx_rate_limit }}/{{ tx_rate_limit }} {{ rx_burst_rate }}/{{ tx_burst_rate }} {{ rx_burst_threshold }}/{{ tx_burst_threshold }} {{ burst_time }}/{{ burst_time }} {{ mikrotik_priority }} {{ rx_rate_min }}/{{ tx_rate_min }} Result: Mikrotik-Rate-Limit = 5000/90000 20000/360000 1400/25200 93/93 8 6350/114300

• Twig filters* Example: Mikrotik-Address-List = {{ tariff.title | upper }} Result: Mikrotik-Address-List = TARIFF (assume that tariff.title = 'tariff') * in addition to default Twig filters one more filter can be used - dec2hex (dec2hex(4))

• Conditions Example: {% if service_attributes.adrlist is not empty %} Mikrotik-Address-List = {{ service_attributes.adrlist }} {% endif %}

  Result: Radius attribute Mikrotik-Address-List will be sent to the router, only if the internet service's additional attribute with the name adrlist is not empty.

Examples

Example 1

We can assign IPv6 prefixes to PPP customers using the RADIUS attribute Framed-IPv6-Prefix:

The route will be created for the IPv6 prefix, to the customer's CPE:

Surely, this example is quite simple and not of much use, because then Splynx will setup the same IPv6 prefix to all customers.

Example 2

We can reconfigure the previous example a bit to get the IPv6 prefix from the additional field

Firstly, we have to add the additional field to the Internet services within Splynx, called 'IPv6 prefix':

Then we can define the IPv6 prefix in the customer's services:

Thereafter, we can assign the value of the additional field to the RADIUS attributes:

It's possible even to check if the parameter exists - send it in Radius reply. If field in Splynx is empty, don't send it in Radius reply:

It is possible to check that the parameter exists by sending it in the radius reply. If the field is empty within Splynx, it will not be send in the radius reply

Example 3

Address-List depends on Tariff plan settings

Let's add an additional field to the internet plan named wan:

Navigate to Config/Networking/Radius

Load the Nas Type: Mikrotik

Add the following in the text box for Rate-Limit attributes:

Mikrotik-Address-List = {{ tariff_attributes.wan }}

It is good practice to add the same value to the FUP CoA Rate-Limit attributes, FUP CoA Restore attributes, CoA Restore attributes fields.

Result should be:

After reconnecting, the customer should be added to address-list wan1, or wan2 depending on the plan settings.

Example 4

Custom IP address.

This example illustrates how to assign any IP address to a customer's device. You do not have to add IPv4 networks to Splynx in this scenario.

1. Create the additional field for internet services. In this example we've named it ip.

   

2. Open Radius configuration (Config/Networking/Radius/Load) and add this line to Rate-Limit attributes:

   Framed-IP-Address = {{ service_attributes.ip }}

   Where "ip" is the name of additional field, that we have added in the first step.

3. Save the changes and Restart Radius to apply changes.

   

4. Set the IP address for the internet service of the ccustomer.

5. Connect a device. Server:

Client:

In this case, the custom IP address overrides the IP address that is chosen in Splynx. If the custom IP address is not entered, the IP address will be set to 0.0.0.0 ! If you only want to override IP addresses when a custom IP address is entered (is not empty), add the following lines to the Rate-Limit attributes:

{% if service_attributes.ip is not empty %}
Framed-IP-Address = {{ service_attributes.ip }}
{% endif %}
