Multi-Functional Ethernet Test Solution

Loopback Testing

Automatically loopback packets for convenient remote network testing

  Brochure

PacketExpert™ can automatically loopback packets from the destination to the source. PacketExpert™ supports layer-wise loopback as well as smart loopback.

PacketExpert™ 10GX supports loopback capability on all 1 Gbps ports and two 10 Gbps ports.

Loopback Types

  • Smart Loopback - Analyzes incoming traffic, automatically detects and swaps Source and Destination MAC and IP addresses and UDP ports before sending back the packet
  • Layer 1 - Loops back incoming packets as is
  • Ethernet - Swaps Source and Destination MAC addresses before sending back the packet
  • IP - Swaps Source and Destination MAC addresses, IP addresses before sending back the packet
  • UDP - Swaps Source and Destination MAC addresses, Destination IP addresses, and UDP ports before sending back the packet



Layer 2 -Ethernet swaps Source and Destination MAC addresses

Loopback facilitates end-to-end testing when the other end is in a remote place. In such cases, one PacketExpert™ can be put in constant loopback at the remote end, and bit error rate tests can be started / stopped anytime at the local end.
