10/100 Mbps Ethernet, 2-port, SmartMetrics™Module
LAN-3102A
Product Overview
The LAN-3102A is a 2-port full/half duplex, Ethernet/Fast Ethernet SmartMetrics 600 or SMB-6000B chassis.The LAN-3102A is a low cost, high value module that has the same application compati­bility, automation, and feature set of the powerful SmartBits LAN-3101A module.
The LAN-3102A is a cost-effective module, perfectly suited for end-user test environments that require the portability offered by the SMB-600 chassis. GPS can be used for end-to-end latency testing of WAN's and in dis­tributed network tests. The module makes testing networks in the field more cost effective, flexible, and capable.
The LAN-3102A is designed for IEEE-compliant 10Base­T and 10Base-TX systems and supports autonegotiation, VLAN tagging, and flow control to the IEEE standards of
802.3p, 802.3Q, 802.3ac, and 802.3x.
module for the SmartBits®SMB-
Product Features and Benefits
Low Cost - satisfies start-up budgets, while providing a
high degree of functionality to test the complex net-
work configurations required to develop, test, and vali-
date Layer 2 and Layer 3 devices.
Full wire-rate traffic generation and analysis - enables
stress testing and capacity analysis.
Data integrity checking - allows verification of payload
data through the DUT.

SmartMetrics Test Functions
The SmartMetrics tests emulate live network traffic. They provide information about the relationships and timing of frames so you can evaluate the functionality and perform­ance of a device under load. They dynamically track data per stream and any change in latency. SmartMetrics tests include:
Sequence Tracking: This provides throughput and frame loss testing on a per-stream basis. This test also provides precise readings of the number of frames received in and out of sequence.
Latency over Time: The user selects a time interval such as every 10ms. For each port, the test records the number of frames received, minimum latency, and maximum latency.The test also calculates the average latency for each port.
Latency per Stream: This test records the minimum laten­cy and maximum latency, and calculates the average latency for each traffic stream.
Latency Distribution: The user selects up to 16 time inter­vals. Within each time interval and for each stream, the following are displayed: transmitting port number, stream number, and the total number of frames received.
Raw Tags: In this test, frames are stored and sent to the application without any calculations or filtering per­formed on the stream tags received. Up to 130,000 records are stored. Module transmit time, receive time, and delta (in ms) are recorded per tag.
Frame Variation: This test measures variations in how soon one packet follows another in a stream. The test measures, for example, the time interval between packets 1 and 2, then between packets 2 and 3, and so on as the packets arrive at the device under test. This test plots the number of packets that arrive within each of the 16 user­specified time intervals.
