class ContextData(object):
|
|
"""Creates UDP/IPv6 configuration entry and initialize socket API if needed.
|
|
|
|
This object can be used by
|
|
:py:class:`~pysnmp.hlapi.asyncore.AsyncCommandGenerator` or
|
|
:py:class:`~pysnmp.hlapi.asyncore.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
