Configuring the SGW Network Element

To configure the serving gateway (SGW) 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 a network element.
The Network Element Administration page opens in the work area.
On the Network Element Administration page, select the SGW tab and then click Modify.
The Modify Network Element page opens.
Configure the following information:
1. IP Domain ID—This field is reserved for future use.
2. Diameter Realm—Specifies the domain of responsibility for the network element (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 SGW network element is configured.
