pyIOSXR

In the spirit of pyEOS for Arista EOS devices and pyEZ for JUNOS devices, pyIOSXR is a python library to help interact with Cisco devices running IOS-XR.

Install

To install, execute:

pip install pyIOSXR

Documentation

Connect

Connect to an IOS-XR device:

>>> from pyIOSXR import IOSXR
>>> device = IOSXR(hostname='lab001', username='ejasinska', password='passwd', port=22, timeout=120)
>>> device.open()

Load and Compare Config

Load a candidate configuration from a file and show the diff that is going to be applied when committing the config:

>>> device.load_candidate_config(filename='unit/test/config.txt')
>>> device.compare_config()

Discard Candidate Config

If an already loaded configuration should be discarded without committing it, call discard_config():

>>> device.discard_config()
>>> device.compare_config()
>>>

Load, Compare and Merge Config

If you want to commit the loaded configuration and merge it with the existing configuration, call commit_config(): (comment and label is optional parameters)

>>> device.load_candidate_config(filename='unit/test/other_config.txt')
>>> device.compare_config()

>>> device.commit_config(label='my label', comment='my comment')

Merge Config with Timer based autorollback

If you want to commit the loaded configuration with a timed autorollback that needs to be confirmed use the confirmed= keyword on the commit, parameters is seconds to wait before autorollback, values from 30 to 300sec. when using confirmed= you need to do another commit_config() without parameters within the time spesified to acknowledge the commit or else it rolls back your changes. (comment and label is optional parameters)

>>> device.load_candidate_config(filename='unit/test/other_config.txt')
>>> device.commit_config(label='my label', comment='my comment', confirmed=30)
.... Code to do checks etc ....
>>> device.commit_config()

Commit Replace Config

If you would rather commit the config by replacing the existing configuration, call commit_replace_config(): (comment and label is optional parameters)

>>> device.load_candidate_config(filename='unit/test/full_config.txt')
>>> device.compare_replace_config()
>>> device.commit_replace_config(label='my label', comment='my comment')

Rollback Config

After a previous commit, rollback() will return to the configuration prior to the commit:

>>> device.rollback()

Running Show Commands

Any show command can be executed in the following fashion, with the command embedded into the call:

>>> device.show_bgp_summary()
...
>>> device.show_interfaces()
...

Running XML Commands

An arbitrary XML command can be executed with the command:

>>> device.make_rpc_call("<Get><Operational><LLDP><NodeTable></NodeTable></LLDP></Operational></Get>")
...

Close Connection

Call close() to close the connection to the device:

>>> device.close()

Debugging Connection

create a logfile of the communication between pyIOSXR and the router.

>>> from pyIOSXR import IOSXR
>>> import sys
>>> device=IOSXR(hostname="router", username="cisco", password="cisco", port=22, timeout=120, logfile=sys.stdout)

OR

>>> from pyIOSXR import IOSXR
>>> import sys
>>> file = open("logfile.log")
>>> device=IOSXR(hostname="router", username="cisco", password="cisco", port=22, timeout=120, logfile=file)

Thanks

A special thanks to David Barroso! This library is entirely based on David's pyEOS, which is a wrapper around Arista's eAPI for EOS.

Also, many thanks go out to Brady Walsh, without whom staying sane while digging through Cisco docs and XML would have been impossible.
