If you select this test, you must also specify the
Length Type (Packet Length or Frame Length). This
indicates whether you want to specify the length for
each packet as a frame length or as a packet length
when you configure IP traffic.
If you are transmitting IPv4 traffic over an electrical
circuit, you must also indicate whether you are testing
in IPoE or PPPoE Data Mode.
– Layer 3 PING. Select this test to verify connectivity
with another layer 3 or IP device.
– Layer 3 Traceroute. Select this test to trace a
packet’s route as it travels through a circuit to deter-
mine where problems in the network are occurring.
The test is selected.
Discovering another JDSU test instrument
Before you begin testing, you can automatically detect other
JDSU test instruments on the circuit and determine their capa-
bilities.You can then optionally configure key parameters for
your test automatically based on a discovered instrument’s
settings. For details, see “Using J-Connect to discover
another JDSU test set” on page 21.
Initializing the link for IPoE testing
Before you connect the HST-3000 (or HST-3000s) to an
access element on a circuit, and turn the laser on (if you are
testing 1G or 100M optical Ethernet), you must first specify the
settings required to establish connectivity with another
Ethernet device on the circuit (see “Initializing the link for
Ethernet testing” on page 47
).
