On single port, the RFC 2544 test can be done either on Port #2 or Port #3 at a time for PacketExpert™ 1G and the RFC 2544 test can be done either on Port #1 or Port #2 at a time for PacketExpert™ 10G and 10GX.Supports RFC 2544 on single or dual Electrical/Optical ports.Throughput, back-to-back, latency and frame loss testing supporting uni-directional and bi-directional traffic between ports.Multi-board support for all port loopback application.

Both smart loopback (auto layer detection) and selected user-defined layers loopback capabilities for incoming traffic.Multi-board support for wire-speed BERT and BERT/Loopback applications.User-defined header parameters for MAC, VLAN, MPLS, IP and UDP layers.

Support for frame lengths from 64 bytes to Jumbo frames (up to 16000 bytes).

Optional sequence number insertion allows detecting out-of-sequence packets and packet loss.

Single as well as constant rate Bit Error and FCS Error Insertion.

Supports industry standards PRBS patterns 2 9-1, 2 11-1, 2 15-1, 2 20-1, 2 23-1, 2 29-1, and 2 31-1, constant patterns like all ones, all zeroes, alt ones-zeroes and user-defined test patterns ranging between 1 to 32 bits.

#Ethernet loopback tester full

Capable of handling full wire speed BERT, in both directions, on all available ports.

Multi-board support for All Port BERT, BERT/Loopback, RFC 2544, RFC 2544 (Single Port) and All Port Loopback applications.

Testing with stacked MPLS, up to 3 levels.

Testing with stacked VLAN (Q-in-Q) – up to 3 levels.

Field upgradable technology allows tester to stay current with industry trend.

BERT testing is also supported on Layer1.

BERT, RFC 2544 Testing over Framed Ethernet (Layer2), Stacked MPLS (Layer2.5), IP and UDP.

Wire-speed BERT, RFC 2544, RFC 2544 (single Port), Loopback, and WAN Link Emulation.

User selectable Electrical and/or Optical interface for Port2 and Port3 allows mixed technology testing.

Traffic options lets technicians generate Ethernet to IP frames with user-configurable frame length, and frame size with varying traffic rates.

Control multiple hardware units from a single GUI, multiplying the number of ports available per system.

Capable of generating/receiving Ethernet to IP traffic at wire speed.

mTOP™ Probe with PacketExpert™ 1G tester - a hardware unit designed for easier portability and convenient for field testing.

HD-PacketExpert™ in mTOP™ rack enclosure - a higher density 12/24 GigE ports form factor solution.

2 of the 4 ports can be optical supporting 100/1000 Mbps line rate Full Duplex mode.

All 4 ports can be electrical supporting user-defined or auto-negotiated speed of 10/100/1000 Mbps Full Duplex mode.

USB based Quad Ports Ethernet / IP Tester.

The electrical ports support 10/100/1000 Mbps, and optical ports support 100/1000 Mbps using SFP. Two of the 4 ports in the PacketExpert™ unit support both electrical and optical interfaces per unit, enabling testing on optical fiber links as well. It can be used as a general purpose Ethernet to IP performance analysis tool for 10 Mbps, 100 Mbps and 1 Gbps Ethernet local area networks and wide area networks (WAN). It truly takes confusion out of Ethernet / IP testing at all protocol layers - from Layer1 frames to IP/UDP packets.

Further, PacketExpert™ also supports optional applications for advanced testing such as Record and Playback, ExpertSAM™, PacketBroker, Multi Stream UDP/TCP Traffic Generator and Analyzer, and ExpertTCP. RFC 2544 is applicable for Layers 2, 2.5, and 3, and Loopback is applicable for Layers 2, 3, and 4. BERT is implemented for all layers (as depicted below). Each GigE port provides independent Ethernet/VLAN/MPLS/IP/UDP testing at wire speed for applications such as BERT, RFC 2544, and Loopback.

You stand no chance to send something over one physical ethernet interface and receiving it at the same end.PacketExpert™ is a portable (USB based) Quad Port Ethernet / VLAN / MPLS / IP / UDP Tester with 4 Electrical Ethernet Ports (10/100/1000 Mbps) and 2 Optical Ports (100/1000 Mbps). Either your network is f*cked up or you use techniques like Spanning Tree to explicitely prevent your signal to be ever routed back to you.Īs you can see, the internal data routing is essential. broadcast packages) lead to serious trouble in the network.Ĭase #3: You have a complicated network setup where loops are possible. It does not make sense to do it and would in some cases (e.g. The switch will in its routing automatically never send the signal back to the source. The NIC has no interest in reading its own signal while sending it.Ĭase #2: The NIC sends the data to a switch. Nobody will talk back to the NIC about the signal. However I doubt you will ever be able to test the PHY without a second receiver.Ĭase #1: The NIC sends the data to a hub (do these still exist?).

As you may have guessed, this is not a bug but a feature (and an essential one).
