Use genie parser on text files

[petritberisha]

Hello everyone,

is there a possibility to use the genie parser on output saved in text files?

The issue is that that it is not possible to install pyATS or genie on the machine where I can access the devices. What I can do is get the output of "show ip interface" save that to a text file and have genie parse that file on my machine.

I could use the NTC TextFSM parser, but wanted to know and learn if it is possible to use genie offline, so to say.

Thank you very much.

Kind regards,

Petrit

Hello,

You can use the pyats-genie-command-parse  library as follows

from pyats_genie_command_parse import GenieCommandParse


parse_obj = GenieCommandParse(nos='ios')
data = parse_obj.parse_file(show_command='show version', file_name_and_path='./show_version.txt') 
print(data)

This is a library to be able to parse NOS command output using the available Genie parsers, it seperates out needing to create a testbed.yml, and allows you to just get the output, and parse the output with Genie parsers.

Hi,

I tried using this "pyats_genie_command_parse", seems that some command works some didn't...Eg. are "show interfaces GigabitEthernet2/0/3 counters" or "show authentication sessions interface GigabitEthernet2/0/48 details" (to see NAC session in switchport).

These command always throw an exception. Did I miss something? Seems that those with an interface name have this issue...

ModuleNotFoundError: Could not find module_name for command show interfaces xxx counters for nos iosxe from genie: cli() missing 1 required positional argument: 'interface'

@petritberisha @choywy Were you able to implement genie offline?

from pyats.topology import loader

tb = loader.load("testbed.yaml")

device = tb.devices[hostname]
Hostname from your testbed.yaml file

parsed_result = device.parse(command, output=output)
Where output is the output of the command, a string
