4.1 Loopback Setup
The Loopback Setup screen is used to configure and initiate loopback diagnostics. Packets are
looped back at the User or Network port based on the Loop Test MAC address of the 9145E10G;
all packets not addressed to the Loop Test MAC Address are dropped. The 9145E10G can be
configured to swap origination and destination MAC addresses of the test packets and to recal-
culate the CRC of the looped packet when the MAC addresses are swapped, so the loopback
packet can successfully navigate through the network back to the test originator.
At the Diagnostics menu, select Loopback Setup (1) and press Enter. The Loopback Setup
screen (Figure 4-2.) opens. Type the number of the function to change, and press Enter. Cycle
through the available settings using the Space Bar. Once the setting has been selected, press
Enter to lock it. Continue to modify the settings as required. To return to the Diagnostics menu,
press Esc.
NOTE: Do not swap the source and destination and recalculate the CRC.
