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:
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
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
