Asymmetric test function

is used to check operability of communication
link that has different transmitting and receiving rates.
By testing two ETS-1000 should be used: local and remote. On the local
device the test parameters are set. The remote device is on the other end of
asymmetric channel. Test traffic generation can be performed in two ways:
1. From local device to remote. In this case the port A(B) is set as a source
port. Port Remote is selected as a destination one.
2. From remote device to local. In this case the port Remote is set as a
source port. Port A(B) is selected as a destination one.
Connection scheme is shown on the fig. 5.28.
Figure 5.28. Connection scheme
Tests for which the function is available are listed below:
1. RFC 2544: throughput, frame loss, back-to-back.
2. BERT (L2, L3, L4).
3. Complex traffic.
Note: To transmit data UDP protocol is used. Number of server UDP
port is 0 × 9000.

The option is not included in the basic configuration; should be purchased additionally.
