-
Interface category
10GE and 1GE Ethernet
-
Number of test ports
2 x 10GE and 4 x 1GE
-
Interface options
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-P2BTL 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)
-
ARP/PING
Supported (configurable IP and MAC address per port)
-
Field upgradeable
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
-
Tx disable
Enable/disable of optical laser or copper link
-
IGMPv2 multicast join/leave
IGMPv2 continuous multicast join, with configurable repeat interval
-
Oscillator characteristics
• 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)
-
Loopback modes
- 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
256 (wire-speed)
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
-
Bandwidth profiles
Burst size and density can be specified. Uniform and bursty bandwidth profile streams can be interleaved
-
Field modifiers
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
-
Packet payloads
Repeated user specified 1 to 18B pattern, a 8-bit incrementing pattern
-
Error generation
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.
