Supported Platforms and PowerCyclers

Note

pyATS Clean is designed modular to enable community-based contribution model. It is expected user communities will contribute to the pyATS clean stage/steps for support specifics of their given OS/Platform/Powercycler or to close the gap on an any features.

Refer to the Developer Guide documentation to get started in your development.

To use this table, locate the Product that corresponds with your device and fill the os and platform keys into your Testbed YAML.

For example, if the device was a Catalyst 9000, then the Testbed YAML should be as follows:

1
2
3
4
5
6
7
devices:
  catalyst-9000:
    os: iosxe
    platform: cat9k
    custom:
      abstraction:
        order: [os, platform]

Supported Power Cyclers

Power cyclers connection to devices are important to auto-recover the device by force reset/power off/on the devices when they have lost connectivity. pyATS Clean provides a feature for recovering devices in the testbed if they are in a hung state. Recovery is invoked if connecting to the device fails, or if an exception is thrown while the device is being upgraded.

As a brief overview, recovery includes the following steps:

  • Connect to Power Cycler and perform power cycle.

  • Connect to device and break the boot sequence, in order to bring the device to loader/rommon prompt.

  • Boots the devices with ‘golden_image’ provided as part of clean file.

  • Pass control back to pyATS Clean.

The following table specifies the current set of PowerCycler types supported by pyATS Clean.

  my-esxi:
    # Fill out the rest of this device as normal
    # such as connection info, credentials, etc

To use this table, locate the PowerCycler that corresponds with yours and fill the arguments into your Testbed YAML under the device peripherals key.

For example, if the PowerCycler was a dualcomm connected to PE1, then the Testbed YAML should be modified as follows:

1
2
3
4
5
6
7
8
devices:
  PE1:
    peripherals:
      power_cycler:
        - type: dualcomm
          connect_type: snmp
          host: 127.0.0.1
          outlets: [22]

You could have more than one PowerCyclers connected to your device. For example, if you have two PowerCycler with dualcomm type connected to PE1, then the Testbed Yaml looks like this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
devices:
  PE1:
    peripherals:
      power_cycler:
        - type: dualcomm
          connect_type: snmp
          host: 127.0.0.1
          outlets: [22]
        - type: dualcomm
          connect_type: snmp
          host: 127.0.0.2
          outlets: [20]
