Networking Requirements
As shown in
Ethernet network, and GE 0/0/2 is connected to users.
A local MAC swap loopback test needs to be performed on GE 0/0/2. A tester sends Ethernet
frames to Switch B. After the source and destination MAC addresses of the Ethernet frames are
swapped on GE 0/0/2, the Ethernet frames are sent back to the tester through GE 0/0/1. The
