+class ContextData:
+    """Creates UDP/IPv6 configuration entry and initialize socket API if needed.
+
+    This object can be used by 
+    :py:class:`~pysnmp.entity.rfc3413.oneliner.cmdgen.AsyncCommandGenerator` or
+    :py:class:`~pysnmp.entity.rfc3413.oneliner.ntforg.AsyncNotificationOriginator`
+    and their derevatives for forming SNMP PDU and also adding new entries to
+    Local Configuration Datastore (LCD) in order to support SNMPv1/v2c with
+    SNMPv3 interoperability.
+
+    See :RFC:`3411#section-4.1` for SNMP Context details.
+
+    Parameters
+    ----------
+    contextEngineId : str
+        Uniquely identifies an SNMP entity that may realize an instance of 
+        a MIB with a particular contextName (:RFC:`3411#section-3.3.2`).
+        More frequently than not, ContextEngineID is the same as 
+        authoritative SnmpEngineID, however if SNMP Engine serves multiple
+        SNMP Entities, their ContextEngineIDs would be distinct.
+        Default is authoritative SNMP Engine ID.
+    contextName : str
+        Used to name an instance of MIB (:RFC:`3411#section-3.3.3`).
+        Default is empty string.
+
+    Examples
+    --------
+    >>> from pysnmp.entity.rfc3413.oneliner.ctx import ContextData
+    >>> ContextData()
+    ContextData(contextEngineId=None, contextName='')
+    >>> ContextData(OctetString(hexValue='01020ABBA0'))
