umnet-napalm 1.2.3

A custom version of NAPALM for UMnet

umnet-napalm

This is a project that augments the NAPALM library in ways that are relevant to our interests. More specifically, new getter functions have been implemented to pull data from routers and parse it into a vender agnostic format.

The following platforms all have their own umnet-napalm drivers. Most of these inherit from other libraries.

• ASA does not inherit - the NAPALM community ASA driver uses the web API which is currently impractical for us.
• IOS inherits napalm.ios.IOSDriver
• IOSXRNetconf inherits napalm.iosxr_netconf.IOSXRNETCONFDriver
• Junos inherits napalm.junos.JunOSDriver
• NXOS inherits napalm.nxos_ssh.NXOSSSHDriver
• PANOS does not inherit - the NAPALM community PANOS driver but it doesn't support connecting via Panorama.

See the umnet_napalm Abstract Base Class definition to see what commands are supported across all platforms. For platforms that inherit from core NAPALM drivers, refer to the getter matrix. For PANOS see napalm-panos repo

Using umnet-napalm

When you install the code it comes with a cli script called umnet-napalm-get. You can use this to run a command against a particular device. Note that umnet-napalm doesn't inherently know the platform or the credentials to use. You can supply all of these on the cli as arguments, or you can set the credentials as environment variables. Here are the different environment variables you can set:

export NAPALM_PASSWORD=<redacted>
export NAPALM_USERNAME=automaton
export NAPALM_ENABLE=<redacted>

## only if you want to query ngfw devices
export PANORAMA_API_KEY=<redacted>

Note you currently can't pass a Panorama API key as a cli argument (because that's just messy) - you must set it in your environment. When querying a Panos device via Panorama you must provide --pan-host [panorama hostname] and --pan-serial [serial number of the firewall]

Here's some quick examples. You can reference umnet_napalm.models for expected output format. Output is in json:
