+
+The **`iceLocalUsernameFragment`** property of the {{domxref("RTCTransportStats")}} dictionary is a string that indicates the local username fragment ("ufrag" or "ice-ufrag") that uniquely identifies the ICE interaction session managed by this transport.
+
+## Value
+
+A string containing the username fragment that uniquely identifies the ongoing ICE session on the transport.
+The same fragment is used to identify the section for any communication with the STUN server.
+The string may be up to 256 characters long, and has no default value.
+
+This has the same values as the corresponding local {{domxref("RTCIceCandidate.usernameFragment")}} property.
+It will change if the connection is renegotiated, for example on ICE restart, or if {{domxref("RTCPeerConnection.setLocalDescription()")}} is called.
