Verifying the configuration
A POS terminal device sends a POS request packet. The Router A and Router B process the packet and
forward it to the bank FEP. The FEP receives the request packet and responds with a reply packet. The
POS terminal device receives the reply packet.
Backup FEP configuration example (nontransparent mode)
Network requirements
Router A provides POS access service for the POS terminals. FEP-A is the primary FEP and FEP-B is the
backup FEP for POS 1 and POS 2. FEP-B is the primary FEP and FEP-A is the backup FEP for POS 2 and
POS 4.
FEPs have POS access enabled and use the listening port 2000.
