Ethernet
The Ethernet measurement mode (additional purchase required)
enables you to analyze internet protocol (IP) performance through the
Ethernet. To perform and display Ethernet measurement data, use the
following tests:
Throughput Test
Displays throughput (upstream and downstream) test results. (See
“Displaying Throughput Results” on page 227 .)
Packet Loss Test
Displays packet loss (round trip) test results. (See “Displaying Packet
Loss Results” on page 228 .)
Ping Test
A ping test verifies the overall downstream/upstream communication
route and connectivity of a DSAM within the Ethernet system. The ping
test enables you to select the IP address, packet size, and time
between pings and displays ping test result data that includes; round
trip time, time-to-live (TTL), packets sent and lost, average round trip
time, and loss to sent ratio. (See
“Running Ping Results” on page 228 .)
Configuring
DSAM for
Ethernet Tests
Typically, an Ethernet test is conducted using the DHCP server on the
network to assign an IP address to DSAM. If the network is expecting
a specific fixed IP address (no DHCP assignment available), you must
configure the Ethernet network settings in the DSAM configuration.
See
“Configuring Ethernet Settings” on page 39 for detailed instruc-
tions.
IMPORTANT
Be sure to return the Obtain IP Address From setting to DHCP after
your test to avoid any conflicts on a different network.
NOTE
It may be necessary to emulate a subscriber's CPE (customer
premises equipment, such as the subscriber's PC or gaming
device). If so, connect the DSAM in place of the device and insert-
ing the MAC address of the device in the DSAM configuration. See
“Other Settings” on page 65 .
