Feature Changes
Limited GTPP Group Configuration for APN
The AAA proxy allocates a lot of memory on a per GTPP group basis statically regardless of the usage. So if the
number of GTPP groups is reduced to around 3 then the issue with the AAA proxy going to warn memory state will not
be observed.
number of GTPP groups is reduced to around 3 then the issue with the AAA proxy going to warn memory state will not
be observed.
Previous Behavior: Up to a maximum of 32 GTPP groups were allowed to be configured per APN.
New Behavior: Now there is a limit of configuring only up to six GTPP groups per APN. In case customers are using
more than six GTPP groups, the AAAProxy will use more memory than is supported and will be in “warn” state of
memory.
more than six GTPP groups, the AAAProxy will use more memory than is supported and will be in “warn” state of
memory.
Customer Impact: On an analysis, it is determined that customers have not yet exceeded a maximum of six GTPP
groups in the configuration. With the reduction in the number of GTPP groups configured, there will no CDR loss due
to AAA proxy kill as CDRs are archived in AAA manager when AAA proxy goes to warn state.

CSCul88752 - Std GTPP dictionaries should support multiple data record
format version
Applicable Products: S-GW
Feature Changes
Support for Multiple Data Record Format Versions
Previous Behavior: Currently, the value of the data record format version was taken according to the GTPP dictionary
being used. Due to this, same data record format version was maintained for all 3GPP Release versions i.e. for Rel. 8,
Rel. 9 and Rel. 10.
being used. Due to this, same data record format version was maintained for all 3GPP Release versions i.e. for Rel. 8,
Rel. 9 and Rel. 10.
With default configuration, because of version mismatch the GTPP request was discarded while using Rel.10 attributes.
New Behavior: A new CLI command “
gtpp data-record-format-version
” is being introduced to configure the
data record format version for the GTPP group.
With this release, the data record format version can be configured based on the 3GPP release version.
Important:
This behavioral change is applicable only to custom24 standard and custom35 GTPP dictionaries for
S-GW.
