Ethernet Line Loopbacks
The loopback can be applied separately for each one of the interfaces.
Ethernet loopbacks can be set in the Maintenance section of the Eth Ports page.
Figure 10-2 Ethernet Line Loopback
This section allows configuring the following parameters:
Line Loopback – checkbox to enable loopback on the port. Internal (towards the
radio side) loopback is available, with specific MAC addresses swap.
Loopback MAC Swap – Loopback is performed with MAC addresses swap
(swapping DA and SA) for the address specified only. All other MAC addresses
not looped.
Loopback Timeout – in seconds. Loopback will clear when timeout expires (up to
24 hours, 0= no timeout).
Internal Line Loopback
An Internal loop returns the received frames to the radio side, enabling you to test
Ethernet traffic across the link.
The Ethernet traffic from the Customer’s end-equipment or Ethernet analyzer is looped
at the Ethernet interface of the remote system, enabling testing of the connection
(cable/fiber), the interface between end-equipment and the local system, both local and
remote systems and the radio transmission.
10.5.3
Radio (RF) Loopback
The Ethernet traffic from a customer’s end-equipment or Ethernet analyzer is looped on
the system’s radio output, enabling testing of the connection (cable/fiber), the interface
between the system and end-equipment and the local system.
The loopback is set with MAC Address swapping for the specified MAC address on
specific modulation profile set by the user.
