Genie parser "show inventory" error on some IOS platforms

[Johannes Luther]

Hi pyATS community,

just to let you know - or maybe I did anything wrong ... There are errors with the genie parser "show inventory" on some IOS devices.

Steps to reproduce the problem

1. Include a C6880 (Sup2T based systems) in the testbed:
   

   devices:
     myDevice:
       connections:
         ssh:
           ip: 192.0.2.1
           protocol: ssh
       os: ios
       series: Cisco Catalyst 6880-X-LE Switch
       type: distribution

2. Run genie parse:

   genie parse "show inventory" --testbed-file lab.yaml --devices myDevice

   Error:
   

   Issue with the parser show inventory
   
   
   Traceback (most recent call last):
     File "src/genie/cli/commands/parser.py", line 289, in genie.cli.commands.parser.ParserCommand.parse
     File "src/genie/conf/base/device.py", line 529, in genie.conf.base.device.Device.parse
     File "src/genie/metaparser/_metaparser.py", line 302, in genie.metaparser._metaparser.MetaParser.parse

   genie.metaparser.util.exceptions.SchemaMissingKeyError: Missing keys: [['slot']]

Other parsers with the same device work as expected. Example:

genie parse "show version" --testbed-file lab.yaml --devices myDevice
{
  "version": {
    "chassis": "C6880-X-LE",
    "chassis_sn": "XXXXXXXXXXXXXXXXXXXX",
    "curr_config_register": "0x2102",
    "hostname": "myDevice",
    "image_id": "c6880x-IPSERVICESK9-M",
    "image_type": "production image",
    "last_reload_reason": "power-on",
    "main_mem": "2997247",
    "number_of_intfs": {
      "Ten Gigabit Ethernet": "16",
      "Virtual Ethernet": "3"
    },
    "os": "IOS",
    "platform": "c6880x",
    "processor_type": " Intel(R) Core(TM) i3- CPU @ 2.00GHz ",
    "rom": "System Bootstrap, Version 15.1(02)SY01 [ Rel 1.1], RELEASE SOFTWARE",
    "rtr_type": "C6880-X-LE",
    "system_image": "bootdisk:/c6880x-ipservicesk9-mz.SPA.152-1.SY4.bin",
    "system_restarted_at": "17:47:43 MESZ Tue Aug 22 2017",
    "uptime": "2 years, 14 weeks, 14 hours, 13 minutes",
    "uptime_this_cp": "2 years, 14 weeks, 13 hours, 8 minutes",
    "version": "15.2(1)SY4",
    "version_short": "15.2"
  }
}

Im running the latest release (19.11)

pip list | grep genie
genie                        19.11

Anything I did wrong here?

Best regards

Hi Johannes,

Hmm that is not good at all. Your set up is correct though. I can see from the documentation that 'show inventory' can be parsed with iOS devices.

The error in particular looks like its complaining that "slot" is not a field it can find and therefore falls apart.

Can you provide the CLI output of "show inventory" and I can check this one out?

I've attached a screenshot of what the desired output should look like in case you wanted to see what it should show :)

Hmm - If you can Johannes, upgrade your pyATS/Genie to the latest 20.2 edition with the command "pyats version update" and try parsing 'show inventory' again.

Hi LanDownUnda :)

thanks for the reply

I upgraded pyATS and genie ... however the suggested command "pyats version update" does not work

$ pyats version update
Usage:
  pyats version [options]

Description:
  Display the installed pyATS version, including all individual components.

Version Options:
  --outdated            Check PyPI for package upgrades
  --include [ [ ...]]   Other packages to include & display

General Options:
  -h, --help            Show help
  -v, --verbose         Give more output, additive up to 3 times.
  -q, --quiet           Give less output, additive up to 3 times, corresponding to WARNING, ERROR,
                        and CRITICAL logging levels

I upgraded the packages using pip.

With the new version, the "show inventory" parser for the Cat6k works as expected.
I didn't test it again since then with the new version ... :) But good to know it works now and it was not some usage error on my side (which could have been the case, because I'm brand new to pyATS/Genie).

Anyway - thanks for letting me know!!!
