▀ P-GW Enhancements for 17.1
▄ Release Change Reference, StarOS Release 17
376
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.
