Pyats- topology file

[SreekaanthGanesan3775]

Hi All,

I have been reading up on pyats and would like to know how to create a topology file as a dict like {'hostname':'ip"} instead of the yaml file shown in the examples. The reason why I want to go with that method is becuase I am trying to connect to a few hundred devices to run specific show commands and store the output in a server. 

Any help is appreciated!.

Thanks in advance!

Hello @SreekaanthGanesan3775,

Here's a very simple example of a topology file from the pyats documentation:

# Example
# -------
#
#   creating a simple testbed topology from scratch

# import testbed objects
from pyats.topology import Testbed, Device, Interface, Link

# create your testbed
testbed = Testbed('manuallyCreatedTestbed',
                  alias = 'iWishThisWasYaml',
                  passwords = {
                    'tacacs': 'lab',
                    'enable': 'lab',
                  },
                  servers = {
                    'tftp': {
                        'name': 'my-tftp-server',
                        'address': '10.1.1.1',
                    },
                  })

# create your devices
device = Device('tediousProcess',
                alias = 'gimmyYaml',
                connections = {
                    'a': {
                        'protocol': 'telnet',
                        'ip': '192.168.1.1',
                        'port': 80
                    }
                })

# create your interfaces
interface_a = Interface('Ethernet1/1',
                        type = 'ethernet',
                        ipv4 = '1.1.1.1')
interface_b = Interface('Ethernet1/2',
                        type = 'ethernet',
                        ipv4 = '1.1.1.2')

# create your links
link = Link('ethernet-1')

# now let's hook up everything together
# define the relationship.
device.testbed = testbed
device.add_interface(interface_a)
device.add_interface(interface_b)
interface_a.link = link
interface_b.link = link
