Loopback Adjustment
At the Transport layer (L4) the incoming traffic (packets without errors)
is being retransmitted backward with source and destination IP and
MAC addresses swapping and source and destination TCP/UDP
addresses swapping.
Note: Only frames with destination MAC address and destination IP address
corresponding to MAC and IP addresses of the ETS-1000L are retransmitted.
Loopback Adjustment
Connect the ETS-1000L to the Ethernet network and select Loopback layer
by pressing L button. Additional parameters (IP address, MAC address,
etc.) are being configured using the remote management (see Remote
Management on page 15).
