Configuring the AF Network Element

To configure the application function (AF) network element:

From the Network section of the navigation pane, select Network Elements.
The content tree displays a list of network element groups; the initial group is ALL.
From the content tree, select the AF network element you want to configure.
The Network Element Administration page opens in the work area.
On the Network Element Administration page, select the AF tab and then click Modify.
The Modify Network Element page opens.
Configure the Diameter features:
1. IP Domain ID — Specifies the IPv4 domain identity. This value uniquely identifies the network element if the same IPv4 address is assigned in multiple networks.
  Enter a string of 0-100 characters, using only letters, digits, periods (.) or hyphens (-). If left empty, IP domain mapping is disabled for this network element.
2. Diameter Realm— Specifies the network element's domain of responsibility (for example, example.com).
3. Diameter Identity— Specifies the fully qualified domain name (FQDN) of the network element (for example, ne.example.com).
  Note: A vendor-specified host name and realm name (such as ne.example.com) resolves to an internal DNS server for vendor network access only. For Internet (roaming) access, use the format defined in the 3GPP Technical Specification: host name, network code, country code, and domain name.
  
  A single network element can have multiple Diameter identities with each represented as a separate Diameter connection from the same appliance. Click Add to add the identity to the list. To delete one of the identities, select it form the list and click Delete.
Click Save.

The AF network element is configured.
