In a multi-product
deployment environment where CDRs are received from ePDG, SaMOG (pseudo) and
P-GW (in Local Breakout scenario), the mediation server finds it difficult to
differentiate between the CDRs. Easy identification of CDRs is possible if CDRs
corresponding to each gateway service are mapped to different ports of the same
CGF server. To achieve this, CLI support is provided to configure multiple GTPP
groups with the same CGF server IP address and different port numbers. This
configuration provides the flexibility to send the ePDG, SaMOG and P-GW LBO
CDRs to the same CGF server on different ports.
For ePDG and SaMOG,
different GTPP groups should be configured in the respective call-control
profiles. For P-GW LBO, GTPP group is selected from APN configuration.
Configuration of CGF server with the same IP address but different ports was
not allowed within/across GTPP groups.
New Behavior: This
release allows configuration of CGF server with the same IP address and
different ports across the GTPP groups. With this change, whenever AAA proxy
logs are displayed, it includes both CGF IP address and port.
To support this
functionality, an optional keyword
port has been
introduced in the
statistics CLI commands. When port is specified along with IP
address in these CLI commands, then the CGF server with the specified IP
address and port is only considered. If the port is not specified, then all
GTPP servers with the specified IP address will be considered irrespective of
the configured port.
same IP address and different port is not permitted within a GTPP group. That
is, it is not allowed to configure primary and secondary servers in a GTPP
group with the same IP and different port.
