– Link status—Using the easy-to-interpret LEDs, you can
obtain a quick summary of the state of the link or the
traffic stream you are analyzing. This enables you to
quickly verify circuit integrity, and to identify the source of
a problem on the link.
– Verify end-to-end connectivity—You can ensure physical
layer integrity and verify end-to-end connectivity of a
circuit.
– Link utilization and throughput verification—You can
generate traffic at a specific bandwidth to verify the error
free throughput of a link. The HST allows you to loopback
frames at the far end to qualify the link in both directions.
– BER testing—You can verify circuit performance by trans-
mitting and analyzing BERT patterns.
– Identify problems with faulty interfaces—You can perform
basic troubleshooting of links and verify the capability of
network elements to support reliable communications by
transmitting standard frames and packets over a circuit.
– Event log. A new event log now displays the date and
time that significant events, errors, or alarms occurred
during the course of your test.
– Optional color display. If your base unit has a color
display, a green Summary results screen indicates that
key test results were acceptable (and no errors were
detected); a red screen indicates results are errored, and
a yellow screen indicates that results occurred that
require additional research. For additional details on the
color display, see the HST-3000 Base Unit User’s Guide.
– Q-in-Q support. You can configure, transmit, and analyze
Q-in-Q encapsulated traffic.
– PPPoE support. You can configure your unit to emulate a
PPPoE client and test over PPPoE links.
– IPv6 support. If you purchased the IPv6 Traffic option, you
can transmit and analyze IPv6 traffic in terminate and
monitor/through modes.
