Genie CLI makes config changes to line console and line default on IOSXR

[pwoconnor]

Everytime Genie connects to a IOSXR device it makes configuration changes the line console and line default. Is there a way to turn that feature off?

Yes you can deactivate them

https://pubhub.devnetcloud.com/media/pyats-packages/docs/unicon/user_guide/connection.html

device.connect(init_exec_commands=[], init_config_commands=[])

These will remove all initial command send when connecting.

[pwoconnor]

Thanks jeaubin, but that is for creating pyats connections. My question is specifically about GenieCLI which works off of a yaml file with connection parameters. Now I would assume that I need what you linked, but I am not sure where they would go in the testbed yaml file.

[jeaubin]

I see;

I'll need to do some test on my side first to make sure it works as expected. I'll be back in the office on Tuesday.

[jeaubin]

We will release a new version of Unicon to allows this. The planned released is for next Tuesday.

Thanks for reporting it!

[pwoconnor]

Any news on the release for Unicon to alleviate this issue?

[karmoham]

Hi Patrick,

We released unicon version 19.4.0 so please upgrade the package and let us know if it solves your issues.

pip install --upgrade unicon

Thanks, Karim

[pwoconnor]

New update does the same thing I reported, when running genie learn, When the session is connected. The program goes straight into config mode and commits various timeout values for line console and line default.

@jeaubin to comment

[jeaubin]

Hi @pwoconnor , Sorry for the delay, I've done the enhancement, however, there has been some issue with the release. We are currently in Business trip; I'll publish it once we come back, early next week.

[pwoconnor]

Ok thanks for the update!

[pwoconnor]

Hi @jeaubin Do you still plan on releasing this week?

[jeaubin]

Hi @pwoconnor , it is now released as a beta package!

Sorry for the delay, Here how to get the latest version

pip install unicon --upgrade --pre

(--pre for beta packages)

And here how to set it up in your yaml files

devices:
  nx-osv-1:
      type: 'router'
      os: 'nxos'
      alias: 'uut'
      tacacs:
          login_prompt: "login:"
          password_prompt: "Password:"
          username: "admin"
      passwords:
          tacacs: admin
          enable: admin
          line: admin
      connections:
          defaults:
            class: 'unicon.Unicon'
          cli:
              protocol: telnet
              init_exec_commands: []
              init_config_commands: []
              ip: "1.1.1.1"
              port: 17036

[pwoconnor]

Awesome, Thanks @jeaubin !!! That has resolved my issue. I truly appreciate it!.

[theotherswan]

So at this, can we run pip install --upgrade unicon, or

we still have to use the beta package and run pip install unicon --upgrade --pre

Thank you so much pwoconnor for bring this issue up.

[jeaubin]

@theotherswan - Unicon has been released with this enhancement. You can just do

pip install --upgrade unicon

[theotherswan]

Thank you jeaubin. So with the upgrade we still need to build our testbed file as follow:

devices: nx-osv-1: type: 'router' os: 'nxos' alias: 'uut' tacacs: login_prompt: "login:" password_prompt: "Password:" username: "admin" passwords: tacacs: admin enable: admin line: admin connections: defaults: class: 'unicon.Unicon' cli: protocol: telnet init_exec_commands: [] init_config_commands: [] ip: "1.1.1.1" port: 17036

in order to prevent Genie CLI from changing the device's config, correct? Thank you.

[jeaubin]

Yes thats correct.

[theotherswan]

Hi jeaubin, I have about 500 Cisco devices. I can export them from Cisco Prime 3.3 to obtain the following CSV format inventory:

Device FQDN | IP | Device Type device_a.domain | 1.1.1.1 | Cisco Nexus 7700 10-slot device_b.domain | 2.2.2.2 | Cisco Catalyst 6509

Do you have a sample python code to convert this inventory list into a YAML testbed file below?

devices: nx-osv-1: type: 'router' os: 'nxos' alias: 'uut' tacacs: login_prompt: "login:" password_prompt: "Password:" username: "admin" passwords: tacacs: admin enable: admin line: admin connections: defaults: class: 'unicon.Unicon' cli: protocol: ssh init_exec_commands: [] init_config_commands: [] ip: "1.1.1.1" port: 22

I think I would have to convert above Device Type to something Genie CLI would understand (i.e. nxos, ios, etc.). Do you have a link to the official Device Type for all Cisco devices? Thank you so much.
