Asymmetric Test
Asymmetric test function 4 is used to check operability of communication
link that has different transmitting and receiving rates.
For asymmetric test, two ETS-1000 unit should be used: local and remote.
On the local unit the test parameters are set. The remote unit is on the
other end of asymmetric channel. Test traffic generation can be performed
in two ways:

From local unit to remote: In this case the port A(B) is set as a source
port. Port Remote is selected as a destination one.

From remote unit to local: In this case the port Remote is set as a
source port. Port A(B) is selected as a destination one.
Tests for which the function is available are listed below:

RFC 2544: throughput, frame loss, back-to-back.

BERT (L2, L3, L4).

Complex traffic.
