HP COMWARE 7 PYTHON SDK¶
Introduction¶
This library was built to simplify working with HP Comware 7 switches that have a NETCONF API. Rather than to have network developers worry about the underlying NETCONF API, this library provides a means to manage HP Com7 switches through pre-built Python objects that make it extremely easy to get started programming in an HP environment.
Before getting started, it’s important to understand the high level workflow required when using this library, which again, is meant to be fairly straight forward and simple.
Step 1 - Create HPCOM7 object for each HP switch being managed¶
>>> from pyhpecw7.comware import HPCOM7
>>>
>>> args = dict(host='hp1', username='hp', password='hp123')
>>>
>>> device = HPCOM7(**args)
Step 2 - Open a Connection to the Device¶
>>> device.open()
<ncclient.manager.Manager object at 0x7fa5088f98d0>
Step 3a - GET Config Data¶
Nearly all features supported such as Vlan, which is used in an
example below, have a get_config() method.
The object is imported, it is instantiated, and the get_config() can
be called. This method usually returns a Python dictionary with several
key value pairs if the configuration resource exists and if it doesn’t
it’s an empty dictionary.
Examples are below.
Step 3b - CONFIGURE the Device¶
Maybe you don’t want to get any data, but rather want to make a configuration change.
Making a configuration change is a two-step process (for most configuration features).
Step 1 Build the configuration, which creates the appropriate configuration object and places it in a staging area, but does not push it.
Most methods of the feature class to build the configuration are
called build or remove.
Step 2 Execute, or push, the configuration object(s) to the device.
While in most cases, users may just want or need to push a single
object, it is possible to build, or stage, multiple configuration
objects and push them all at once in which case they are executed in the
order as they were built. Each time a build or remove is
executed, a list is being appended to, which is storing the staged
objects.
The final execution (config push) happens by using the execute
method of the HPCOM7 object.
Examples are below.
Getting Started¶
>>> from pyhpecw7.comware import HPCOM7
>>>
>>> args = dict(host='hp1', username='hp', password='hp123')
>>>
>>> device = HPCOM7(**args)
>>>
>>> device.open()
<ncclient.manager.Manager object at 0x7fa5088f98d0>
GET VLAN INFO¶
>>> from pyhpecw7.features.vlan import Vlan
>>>
>>> vlan = Vlan(device, '20')
>>>
>>> vlan.get_config()
{}
>>>
>>>
>>> vlan = Vlan(device, '10')
>>>
>>> vlan.get_config()
{'name': 'VLAN10_WEB', 'vlanid': '10', 'descr': 'VLAN 0010'}
>>>
VLAN 20 did not exist on the switch, but VLAN 10 did.
A VLAN object for any VLAN can also return all VLAN IDs that exist on the switch.
>>> vlan.get_vlan_list()
['1', '10']
CONFIGURE A VLAN¶
Let’s create a new VLAN object.
>>> vlan = Vlan(device, '20')
>>>
Now add VLAN 20. To do this we’ll use the build method.
>>> vlan.build()
True
When True is returned, it means that the config object that will be
pushed has successfully been staged.
The next step is to execute the change.
>>> response = device.execute()
>>>
>>> vlan.get_config()
{'name': 'VLAN 0020', 'vlanid': '20', 'descr': 'VLAN 0020'}
>>>
Setting the vlan name or description could easily be sent in as
additional key value pairs (or with a dictionary) when using build.
>>> args = dict(name='NEWV20', descr='DESCR_20')
>>>
>>> vlan.build(**args)
True
>>>
>>> rsp = device.execute()
>>>
>>> vlan.get_config()
{'name': 'NEWV20', 'vlanid': '20', 'descr': 'DESCR_20'}
>>>
To remove the VLAN, the remove method is used.
>>> vlan.remove()
True
>>>
>>> rsp = device.execute()
>>>
>>> vlan.get_config()
{}
>>>
GET INTERFACE INFO¶
>>> from pyhpecw7.features.interface import Interface
>>>
>>> interface = Interface(device, 'FortyGigE1/0/4')
>>>
>>> interface.get_config()
{'admin': 'up', 'duplex': 'auto', 'speed': 'auto', 'description': 'DESCR104', 'type': 'routed'}
>>>
DEFAULT AN INTERFACE¶
>>> interface.default()
True
>>>
>>> response = device.execute()
>>>
>>> interface.get_config()
{'admin': 'up', 'duplex': 'auto', 'speed': 'auto', 'description': 'FortyGigE1/0/4 Interface', 'type': 'switched'}
>>>
CONFIGURE AN INTERFACE¶
>>> interface.build(admin='down', description='TEST_DESCR')
True
>>>
>>> rsp = device.execute()
>>>
>>> interface.get_config()
{'admin': 'down', 'duplex': 'auto', 'speed': 'auto', 'description': 'TEST_DESCR', 'type': 'switched'}
>>>
