To perform an automatic loopback
1 If you haven’t already done so, launch the Terminate or
Multi-Stream Terminate application for the circuit you are
testing (see
“Launching an application” on page 28 ), and
then select a test (see the appropriate procedure below):
– “Selecting a layer 2 test” on page 46
– “Selecting a layer 3 IP test” on page 120
– “Selecting a layer 4 TCP/UDP test” on page 165
– “Selecting a multiple streams test” on page 182
2 Initialize the Ethernet link (see “Initializing the link for
Ethernet testing” on page 47 .
3 If you are looping back layer 3 or layer 4 traffic, establish
an IPoE connection or a PPPoE session:
– If you are transmitting IPv4 traffic, see “Establishing an
IPoE connection for IPv4 traffic” on page 122 , or
“Establishing a PPPoE session” on page 128 .
– If you are transmitting IPv6 traffic, see “Establishing an
IPoE connection for IPv6 traffic” on page 124 (single
stream tests only).
4 Configure the near end HST as appropriate for your test.
See:
– “Configuring layer 2 Ethernet tests” on page 51 .
– “Configuring layer 3 IP tests” on page 136 .
– “Configuring layer 4 traffic” on page 167 .
– “Enabling streams and specifying the traffic load” on
page 183
and “Configuring traffic streams” on
page 187 .
5 Press the Home button to view the test results display.
6 If you are looping back multiple streams of TCP/UDP
traffic, on the far end HST, specify a listen port for each
enabled stream that matches the destination port in the
corresponding stream received from the near end HST.
See
“Configuring traffic streams” on page 187 .
