The DNS Query emulator is used in the GGSN Nodal , SGW Nodal and MME Node Test cases to simulate Network Host/DNS Server. It is defined in the DN Query Node sub-tab on the Network Devices Tab. Enable the node with the APN DNS Lookup checkbox.
Target ePDG DNS Query Node - Available when you select APN DNS Lookup and ePDG Node Emulation and Test Activity = Command Mode/Sequencer on the SGW Test Configuration tab. Used for APN-DNS support when simulating ePDG.
The DNS Query Node gets an IP address then sends the Create PDP Context with the IP Address provided by the DNS Query Response message.
| DNS Query Node | Enter Ethernet Configuration. Number of nodes from 1 to 1000. Tcl Parameter: DnsNodeAddr |
| Target ePDG DNS Query Node |
Enter Ethernet Configuration. Number of nodes from 1 to 1000. Tcl Parameter: TgtEpdgDnsNodeAddr |
With an Ethernet User Node, you can define:
The IP address and routing options... The IP Address will increment for each node.
The MAC Address to override the Hardware MAC address so the packets sent out of the interface will use the provisioned MAC address rather the Hardware MAC Address.
Custom port selection... and error injection with the Advanced... button.
Select default routing that were configured for the test server.
Select the Next Hop IP Address instead of using the test server's default route.
The Outbound Traffic Port to disable the normal routing function and to force packets out of the selected interface.
