not in LLB or loop back mode.
About asymmetrical Expert RFC 2544 tests
The new RFC 2544 test is useful if the uplink and downlink
speeds on the circuit are different (as illustrated in Figure 13
on page 67). The test can be run end-to-end; no loopback is
required. When you configure the test, you indicate that you
are testing Upstream, Downstream, or in both directions
(Combined).
Upstream - If you are testing Upstream, the master instru-
ment configures a slave instrument to prepare it to receive
traffic, sends traffic, then queries the slave for results
concerning the upstream link.
Downstream - If you are testing Downstream, the slave
generates traffic (as configured on the master instrument),
and then transmits the traffic to the master. Results for the
downstream link are then displayed on the master tester.
