Step Command Remarks
6. (Optional.) Configure the
TCP keepalive parameters
for the POS application
template.
tcp keepalive interval time
count counts
Changes to the keepalive parameters
take effect immediately. When the TCP
connections are terminated because of
the keepalive detection mechanism, it
will not trigger the switch between the
primary and backup FEP if a backup
application template is already
specified.
7. (Optional.) Specify the TCP
connection timeout.
tcp linking-time time
By default, the timeout is 20 seconds.
The configuration takes effect only on
TCP connections initiated after the
configuration.
8. Specify a source IP address
for TCP connections.
source ip ip-address
By default, no source IP address is
specified.
Specifying a source IP address removes
all existing TCP connections that use this
template.
9. Specify a source port
number for TCP connections. source port port-number
By default, no source port is specified.
Specifying a source port number
removes all existing TCP connections that
use this template.
The specified source port must not be one
of the following:
• Listening port for a terminal template.
• Source port for any other application
template.
• Port number for any other system
process.
If you specify a source port number that is
the same as the port number for any other
system process, the source port does not
take effect.
10. (Optional.) Enable sending
of the caller number.
caller-number enable
By default, caller number sending is
disabled.
This feature is supported for application
templates in TCP mode and for POS
dial-up terminals connected to AM
interfaces. For a POS terminal connected
to an AM interface, you must enable the
modem module in TTY view to obtain the
caller number. For more information, see
layer 2—LAN Switching Command
Reference.
11. (Optional.) Configure the
TPDU address change
policy.
tpdu-change { destination |
source }
By default, the TPDU originator address
will be changed.
In nontransparent mode, modifying the
TPDU address change policy removes all
permanent TCP connections that use the
application template.
