• In temporary mode, the router terminates the TCP connection to the FEP when a POS transaction
finishes. The router establishes another TCP connection for a new transaction. The router can
establish concurrent TCP connections with the FEP.
• In permanent mode, for POS transactions in nontransparent transport mode, the router maintains
the TCP connection to the FEP when the first POS transaction finishes. The router uses the TCP
connection to transfer subsequent POS packets.
If an application template is bound to a POS terminal for transparent transport, the router creates a
dedicated TCP connection for the terminal, regardless of the TCP connection mode of the application
template. In this case, the router can establish concurrent TCP connections with the FEP.
Examples
# Create POS application template 1 in TCP mode. Specify the temporary TCP connection mode for POS
application 1.
<Sysname> system-view
[Sysname] posa app 1 type tcp
[Sysname-posa-app1] mode temporary
Connections for the application have been reset.
The output shows that the permanent TCP connection already established by the POS application
template is deleted.
