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 {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 session trace subscriber command in Command Line
Interface Reference.
<trace_ref_id> is the configured Trace Id to be used for this trace collection instance. It is composed of
