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.

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.
