Please follow the steps down below to start NuApps-2544-RM and NuServer properly.

Starting NuServer

When starting NuApps-2544-RM, a “Connect to NuServer” window will pop up and asked how you are going to connect to NuServer.

• Local Host: Choose this option when you’re

running NuApps-2544-RM from NuStreams-2000i IPC module or a PC that’s connected to NuStreams-2000i/600i via an RJ45 cable.

• Remote: Choose this option when you’re

running NuApps-2544-RM from other PC located on the network. Choose the IP address which is assigned from NuStreams-2000i/600i from the scroll-down menu, or choose demo to enter NuApps-2544-RM’s Demo Mode.

Starting NuServer

If an error message window pops up and says “Detecting NuServer System Fail”, please close NuApps-2544-RM and NuServer, and start again.

After starting NuApps-2544-RM, a Select Config window will pop up. You have to reserve ports on module cards before performing tests with NuApps-2544-RM. Please follow the steps down below and make the proper configurations for NuApps-2544-RM.

Port Reserving

As mentioned above, you have to reserve ports on module cards before performing tests with NuApps-2544-RM. You can do so by either Open an Existing Configuration or by Create a New Configuration.

If you have a previously saved configuration file stored in your PC, you can load it and apply all the setting you’ve made by choosing “Open an Existing Configuration” from the Select Config pop-up window.

Configuration files are saved in the format of “＊.xml”, and are named with Tester Name, DUT

Name, and the date/time when the files are created.

If the module card information contained in the configuration file you’ve loaded from your PC has more module cards than your current amount of module cards, a warning message will pop up, showing that “Available ports are not enough”.

XTRAMUS TECHNOLOGIES®

If this happens, please click the OK button, and choose Create a New Configuration from the

Select Config window instead.

Port Reserving

If the port mapping contained in the configuration file you’ve loaded from your PC does not match NuStreams-2000i/600i’s current port mapping, a Port Remapping window will pop up and guides you through port remapping process.

¾ Back: Go back to Select Config window. ¾ Port Remapping: Click the scroll-down menu to choose whether if you would like to remap ports

automatically or manually.

If you choose automatically from the Port Remapping scroll-down menu, NuApps-2544-RM will make the proper port remapping automatically.

The final result of the port remapping will be shown on the Remapping Result field. Press OK to continue.

If you choose manually from Port Remapping scroll-down menu, you will have to make the proper port remapping by yourself.

¾ Remapping Port: This field shows the port

mapping you’ve loaded from file.

¾ Candidate Port: This field shows the current

port mapping.

To make port remapping manually, please choose a port from Remapping Port (1), assign a new

port ID from Candidate Port (2), and click button to add it to the Remapping Result (3).

Protocol

¾ Port No.: This field displays each port’s Port ID. ¾ Protocol: The Protocol scroll-down menu allows you to set each port’s protocol to either Layer 2

or Layer 3-IP.

• Layer 2: Packets will be transmitted and received via layer 2 MAC addresses.

• Layer 3-IP: Packets will be transmitted and received via layer 3 IP addresses.

¾ Port MAC: These fields display the MAC addresses of all ports. ¾ Enable VLAN: VLAN (Virtual LAN) is a group of hosts with common requirements that

communicate within the same Broadcast domain regardless of the physical location. Setting the Protocol to Layer 2 and enabling VLAN allows you to make settings for the following options:

• VID: VID stands for Virtual ID, an ID number for identifying different virtual LANs on the

network. You can set the VID for each port.

• CFI: CFI stands for Canonical Format Indicator, a 1-bit field in frames for compatibilities of

Ethernet and Token Ring networks.

• VLAN Priority: VLAN Priority (IEEE P802.1p) indicates the priority level of frames transmitted

from each port. The value can be set from 0 to 7.

¾ Port IP/Gateway IP/IP Mask: These three fields can only be set when you set the Protocol to

Layer 3-IP. You can input each port’s IP Address, Gateway IP Address, and Default Mask in

these fields.

4.9.2. Test Configuration Overview

NuApps-2544-RM supports four different tests including:

Diagram Description

Throughput test determines the DUT’s maximum capable

throughput rate without dropping any packets. Latency test measures the time it takes for the DUT to forward a

packet. Packet Loss test measures the percentage of packets that are not

forwarded due to the lack of resource.

Back to Back test measures DUT’s buffer capacity by sending bursts of traffic at the maximum frame rate and measuring the longest burst size without dropping any packets.

To start performing tests with NuApps-2544.RM, please check the check box

in front of the test you would like to perform first. Unchecked tests will not be performed, and you cannot access their reports as well during or after the tests. You can access setting options for the tests you would like to perform by:

Accessing Test Setting Pages

• Click the test you would like to configure

located on System Info/ Configuration List

• Click the test you would like to configure

located on the test tab menu.

For more detailed setting options regarding to Throughput, Latency, Packet Loss and Back to Back, please refer to the sections down below.

The duration of time (in seconds) for the test. The range for the testing time is 1~5000. The number of times of the test. The range for the number of times of the test is 1~100. This function allows the DUT to create an address table according to the source address in the received frame.

• Never: DUT will never create an address table, and Learning Mode is

disabled.

• Once: DUT will create an address table only once.

• Every Trial: DUT will create an address table in every trial.

The value set here will be the number of learning packets that will be sent through the ports chosen to be learned for building address table. You can set the delay time after NuApps-2544-RM created an address table according to the source address in the received frame

Enabling this function allows two-way direction transmitting during the test.

The starting/ending size of the transmitted packet. The range of the Starting from/at field is 60~2032. The frame size will increase in arithmetic progression fashion, while the value you set here will serve as its difference. The range of the Frame Size Step is
