POS TCP terminal and TCP application configuration example

As shown in Figure 24, a POS terminal is connected to Router A through an Ethernet interface. Router B is connected to the FEP (Server) through an Ethernet interface. The POS access service has been enabled on the FEP. The listening port number is 2000.

Configure POS access on Router A so the POS terminal can access the FEP.

1. Enable POS access service:

   # Enable the POS access server.

   <RouterA> system-view
   [RouterA] posa server enable
   

2. Configure the POS application:

   # Configure interface Ethernet 1/0.

   [RouterA] interface ethernet 1/0
   [RouterA-Ethernet1/0] ip address 10.1.1.2 255.255.255.0
   [RouterA-Ethernet1/0] quit
   

   # Configure interface Ethernet 1/1.

   [RouterA] interface ethernet 1/1
   [RouterA-Ethernet1/1] ip address 10.1.2.3 255.255.255.0
   [RouterA-Ethernet1/1] quit
   

   # Create application 1 in TCP mode and enter its view.

   [RouterA] posa app 1 type tcp
   

   # Configure a POS multi-application entry that uses POS application 1 as the default POS application.

   [RouterA-posa-app1] map default
   

   # Specify the IP address and port number as 2.2.2.1 and 2000.

   [RouterA-posa-app1] ip 2.2.2.1 port 2000
   [RouterA-posa-app1] quit
   

3. Configure the POS terminal:

   # Create POS terminal 1 in TCP access mode, and configure its listening port number as 3000.

   [RouterA] posa terminal 1 type tcp listen-port 3000
