When emulating PDN Gateway (PDN GW/PGW), Landslide connects to the Serving Node/SUT (MME or SGSN), using the S11 interface in a MME Nodal and PGW Nodal test cases, and S5/S8 interface in SGW Nodal test case, to send session information to the PGW as necessary (such as at MS session establishment) to emulate a flow and responds to requests from the PGW.
The PGW Control Node connects S2a/S2b/S5/S8 in AMF Node and SMF Node to the PGW (When PGW-C Emulation is enabled on AMF Node and SMF Node Emulator Configuration)
You can emulate multiple nodes with the Number of Nodes setting1.
| NOTE: During SGW Nodal testing, the PDN GW Node simulates control plane interface and supports 1000 nodes. |
In PGW Nodal and SGW Nodal test cases, you can enable the Serving Node using the dropdown list on the Test Configuration tab.
|
Use Dual Stack to return both IPv4 and IPv6 addresses when requested. Dual Stack is available for your selection only when you select PGW Node Emulation on the Test Configuration tab. Primary Node Tcl Parameter:
|
|||
|
Alternate |
Available when you select Dual Stack Support. Select Alternate Node Address. Alternate Node Tcl Parameter:
The Alternate Node Address you enter must be of IPv6 format if the Physical Interface address type you select for the node is an IPv4 address and vice versa. |
||
|
Available in SMF Node test case when PGW-C Emulation is enabled. Select to have a Single IP address for both the emulated PGW and SMF Control nodes. Primary IP Address is not available for capture. Tcl Parameter:
|
|||
|
Host |
Available in SMF Node test case when PGW-C Emulation is enabled. Enter the PGW Node host name (fqdn). Enter up to 128 characters. Alternate Node Address. Auto Increment Wizard is available. Default : PGW#(N0).Spirent.com Alternate Node Tcl Parameter:
|
In PGW Nodal test case, selecting the Dual Stack checkbox registers two addresses, an IPv4 address and an IPv6 address.
PGW/LMA node with PMIPv6/IPv6 and GTPv2 supports Dual Stack and enables Alternate Node Address for the node's IPv4 address.
PMIPv6/IPv4 does not support Dual Stack and requires PMIPv6 Source Address (Mapped IPv4 Address and IPv6 Address).
With an Ethernet node, you can define:
The IP address and routing options... The Starting IP 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.
The Outbound Traffic Port to disable the normal routing function and to force packets out of the selected interface.
Custom port selection... and error injection with the Advanced... button.
The GTP Node report tab displays the summary measurements for the gateway nodes.
