10GE and 1GE Ethernet
Number of test ports
2 x 10GE and 4 x 1GE
2 x 10GBASE-SR / LR / LRM / ER / Direct Attached Cable (DAC)* and
4 x 10/100/1000BASE-T** or 1000BASE-X (SFP-MSA) or 100BASE-FX** or 100BASE-BX ***
*The interface implements discrete PHY devices with built in EDC support that employs sophisticated signal processing techniques to recover a 10 Gbps signal that has travelled over a dispersive Copper Direct attach cable and restore a bit-error rate of 10-12 or better.
** Requires Finisar SFP transceiver FCLF-8521-3 with sgmii host interface
*** Requires Source Photonics SFP transceivers with sgmii host interface
Number of transceiver module cages
2 x SFP+ and 4 x SFP
Port statistics (counter size: 64 bits)
Link state, FCS errors, pause frames, ARP/PING, error injections, training packet
All traffic: RX and TX Mbit/s, packets/s, packets, bytes
Traffic w/o test payload: RX and TX Mbit/s, packets/s, packets, bytes
Adjustable Inter Frame Gap (IFG)
Configurable from 16 to 56 bytes, default is 20B (12B IFG + 8B preamble)
Transmit line rate adjustment
Ability to adjust the effective line rate by forcing idle gaps equivalent to -1000 ppm (increments of 10 ppm)
Supported (configurable IP and MAC address per port)
System is fully field upgradeable to product releases (FPGA images and Software)
Histogram statistics (counter size: 64 bits)
Two real-time histograms per port. Each histogram can measure one of RX/TX packet length, IFG, jitter, or latency distribution for all traffic, a specific stream, or a filter
Enable/disable of optical laser or copper link
IGMPv2 multicast join/leave
IGMPv2 continuous multicast join, with configurable repeat interval
• Initial Accuracy is 3 ppm
• Frequency drift over 1st year: +/- 3 ppm (over 15 years: +/- 15 ppm)
• Temperature Stability: +/- 20 ppm (Total Stability is +/- 35 ppm)
- L1RX2TX – RX-to-TX, transmit byte-by-byte copy of the incoming packet
- L2RX2TX – RX-to-TX, swap source and destination MAC addresses
- L3RX2TX – RX-to-TX, swap source and destination MAC addresses and IP addresses
- TXON2RX – TX-to-RX, packet is also transmitted from the port
- TXOFF2RX – TX-to-RX, port’s transmitter is idle
- Port-to-port – Inline loop mode where all traffic is looped 100% transparent at L1
Number of transmit streams per port
Each stream can generate millions of traffic flows through the use of field modifiers
Test payload insertion per stream
Wire-speed packet generation with timestamps, sequence numbers, and data integrity signature optionally inserted into each packet.
Stream statistics (counter size: 64 bits)
TX Mbit/s, packets/s, packets, bytes, FCS error, Pause
Burst size and density can be specified. Uniform and bursty bandwidth profile streams can be interleaved
16-bit header field modifiers with inc, dec, or random mode. Each modifier has configurable bit-mask, repetition, min, max, and step parameters. 2 modifiers per stream for 1G ports and 5 modifiers per stream for 10G ports.
Packet length controls
Fixed, random, butterfly, and incrementing packet length distributions. Packet length from 56 to 16384 bytes
Repeated user specified 1 to 18B pattern, a 8-bit incrementing pattern
Undersize length (56B min) and oversize length (16384 max.) packet lengths, injection of sequence, misorder, payload integrity, and FCS errors
TX packet header support and RX autodecodes
Ethernet, Ethernet II, VLAN, ARP, IPv4, IPv6, UDP, TCP, LLC, SNAP, GTP, ICMP, RTP, RTCP, STP, MPLS, PBB, or fully specified by user
Packet scheduling modes
- Normal (stream interleaved mode). Standard scheduling mode, precise rates, minor variation in packet inter-frame gap.
- Strict Uniform. New scheduling mode, with 100% uniform packet inter-frame gap, minor deviation from configured rates.
- Sequential packet scheduling (sequential stream scheduling). Streams are scheduled continuously in sequential order, with configurable number of packets per stream.
- Burst. Packets per stream are organized in bursts. Bursts from active streams form a burst group. The user specifies time from start of one burst group till start of next burst group.
