Feature Changes
Configuring Session Trace File Type
To address the issues caused when the sesstrc task allocates memory over the allotted limit, under a random subscriber
session trace load tests on P-GW/S-GW, support for B-type XML files is introduced in addition to the A-type files
already supported.
session trace load tests on P-GW/S-GW, support for B-type XML files is introduced in addition to the A-type files
already supported.
Previous Behavior: The file type was A-type XML file and the type could not be changed.
New Behavior: The CLI has been modified (see Command Changes section) to allow the operator to select the file
type generated by session trace. When B-type XML files are used, multiple trace recording session elements will be
encoded in a single XML file. It should be noted that different trace recording sessions may be associated with different
TCEs, according to the TCE IP address specified during activation. As expected, each Type-B XML file will contain
traceRecSession elements that pertain only to the same target TCE. There will be different XML Type-B files created
for different TCEs and they will be placed in different tce_x directories for transmission to the target TCEs.

Command Changes
session trace network-element
The new optional
file-type
keyword enables the operator to determine which type of XML file is generated by the
session trace:
configure
session trace network-element { all | enb | ggsn | hnbgw | mme | pgw | sgw } [ file-
type { a-type | b-type } ] [ collection-timer | tce-mode ]
type { a-type | b-type } ] [ collection-timer | tce-mode ]
no session trace network-element { all | enb | ggsn | hnbgw | mme | pgw | sgw }
end
Notes:
Default file-type is a-type.
To keep the syntax simple, the optional
file-type
keyword must be entered before entering either of the other
optional keywords.
To modify the session trace network-element configuration, you must first enter the
no session trace
network-element
form of the command to remove the session trace configuration.
