Subscriber Session Trace Configuration
This section provides a high-level series of steps and the associated configuration examples for configuring the system
to enable the Subscriber Session Trace collection and monitoring function on network elements s in LTE/EPC networks.
Important:
This section provides the minimum instruction set to enable the Subscriber Session Trace
functionality to collect session traces on network elements on EPC networks. Commands that configure additional
function for this feature are provided in the
Command Line Interface Reference
.
These instructions assume that you have already configured the system level configuration as described in the
System
Administration Guide
and specific product Administration Guide.
To configure the system to support subscriber session trace collection and trace file transport on a system:
Step 1
Enable the subscriber session trace functionality with NE interface and TCE address at the Exec Mode level on an EPC
network element by applying the example configurations presented in the
Enabling Subscriber Session Trace on EPC
Network Element
section.
Step 2
Configure the network and trace file transportation parameters by applying the example configurations presented in the
Trace File Collection Configuration
section.
Step 3
Save your configuration to flash memory, an external memory device, and/or a network location using the Exec mode
command
save configuration
. For additional information on how to verify and save configuration files, refer to the
System Administration Guide
and the
Command Line Interface Reference
.
Step 4
Verify the configuration of Subscriber Session Trace related parameters by applying the commands provided in the
Verifying Your Configuration
section of this chapter.
Enabling Subscriber Session Trace on EPC Network Element
This section provides the configuration example to enable the subscriber session trace on a system at the Exec mode:
session trace subscriber network-element { ggsn | mme | pgw | sgw } { imei
<
imei_id
> } { imsi <
imsi_id
> } { interface { all | <
interface
> } } trace-ref
<
trace_ref_id
> collection-entity <
ip_address
>
Notes:
<
interface
> is the name of the interfaces applicable for specific NE on which subscriber session traces have
to be collected. For more information, refer to the
session trace subscriber
command in the
Command
Line Interface Reference
.
<
trace_ref_id
> is the configured Trace Id to be used for this trace collection instance. It is composed of
MCC (3 digit)+MNC (3 digit)+Trace Id (3 byte octet string).
<
ip_address
> is the IP address of Trace collection Entity in IPv4 notation.
