If you configure POS functions incorrectly (for example, you specify an unavailable TCP port as the
source port for an application template), the functions will not take effect. The display posa status
command displays the POS terminal/application template state as Error after you enable the POS
access service. You can fix the problems (for example, correct the TCP source port for the application
template) and then re-enable the POS access service.
Examples
# Enable the POS access service.
<Sysname> system-view
[Sysname] posa server enable

posa statistics caller-id
Use posa statistics caller-id to add a caller number statistical item. The router counts the packets
exchanged between the POS terminal and the FEP for the caller number.
Use undo posa statistics caller-id to remove the specified caller number statistical item.
Syntax
posa statistics caller-id caller-number
undo posa statistics caller-id caller-number
Default

Parameters
caller-number: Specifies a caller number, a string of 1 to 64 characters. It can contain only numbers and
letters, such as 01012345678. A caller number is typically all numbers, but letters can also be used.
Usage guidelines
This feature applies only to POS terminals using dial-up access mode.
If you configure the same caller number multiple times, no error message is displayed.
The router supports up to 64 caller number statistical items.
Examples
# Add a statistical item for caller number 01012345678 to count the packets between the POS terminal
and the FEP.
<Sysname> system-view
[Sysname] posa statistics caller-id 01012345678
