Command Changes
sgsn-core-nw-interface
The command
sgsn-core-nw-interface
in the Call-Control-Profile configuration is enhanced with keywords to
support S4 interface selection:
config
call-control-profile cc-profile name
sgsn-core-nw-interface {gn | s4 [epc-ue {always | eps-subscribed} non- epc-ue
{never | always | eps-subscribed}]}
{never | always | eps-subscribed}]}
exit
Notes:
When keywords or options are not selected with the selection of the S4 interface option, it implies that the SGSN
will apply S4 interface always for both EPC and Non- EPC devices. This is also synonymous to the CLI
command configured as
command configured as
sgsn-core-nw-interface s4 epc-ue always non-epc-ue always
.
To configure SGSN behavior supported in previous releases, the CLI is configured as
sgsn-core-nw-
interface s4 epc-ue always non-epc-ue eps-subscribed
. This is also the default behavior when
the CLI is not configured.
For more information on the CLI commands see the Command Line Interface Reference.
