5.0.0

IMPORTANT

Starting with this release, NAPALM offers support for Python 3.8+ only.

Python 3.7 support has been dropped (since it is now end-of-life, see https://www.python.org/downloads/release/python-370/), while adding support for Python 3.12.

Breaking changes for Arista EOS

Beginning with this release, NAPALM only supports Arista EOS 4.23 and later. On this occasion, the eos_fn0039_config optional argument has also been removed. This optional argument was used to transform old style configuration to the new style, available beginning with EOS release 4.23.0, as per FN 0039.

3.3.0

NETCONF driver for IOS-XR

Over the last 18 months Cisco has been working on implementing a NETCONF-based driver for the IOS-XR platforms. The new driver is now available in the core NAPALM library, besides the existing driver (which uses the proprietary XML API). The minimum IOS-XR version required is 7.0. Check out https://napalm.readthedocs.io/en/latest/support/iosxr_netconf.html for more information and caveats.

Many thanks to the Cisco team, in particular to @neelimapp and @111pontes for their work, and @ktbyers for coordinating these efforts.

As this is a brand new driver, you may encounter various issues, and we will welcome your reports and pull requests to fix those!

Commit Confirmed

Beginning with this release, NAPALM natively supports commit confirmed operations. See https://napalm.readthedocs.io/en/latest/tutorials/changing_the_config.html#committing-the-configuration-with-a-required-confirmation for more usage details.

New Features

[Junos] Add get_vlans for Junos #1398
[Junos] Added Support for Logical Interfaces Counters #1382
[Junos] Use aply-groups inheritance on get-configuration RPC calls #1363
[Core] Adding cannonical mapping for 25GE, 50GE, 200GE and 400GE interfaces #1329

Bug Fixes

[EOS] Fix for BGP description not found by get_bgp_neighbors in some EOS versions #1356
[EOS] Set next hop to something valid for vxlan routes #1347
[EOS] Fix naplam.get_route_to() not working on EOS:failed to detect a valid IP address from u'' #1346
[IOS-XR] XR 7+: get_lldp_neighbors_detail query only the NodeTable #1404

Bug fixes and behaviour changes

3.1.0

Core changes

• Fix: force_no_enable enabled on ios and nx only #1240
  If you maintain a thrid-party driver using Netmiko for the underlying layer, but that doesn't make use of the enable features typically found on IOS-like devices, it is recommended to pin to this NAPALM version, so it won't break compatibility. See #1241 for more information.
• lxml text retrieval (find_txt) shouldn't fail if no text element available #1242

Driver changes

• [NX-OS] Initial version for nxos_ssh get_optics #1215
• [NX-OS] Fixed get_bgp_neighbors and asdot notation on NX-OS #1230
• [Junos] Fix "KeyError in get_environment() on Juniper MX10k3 with Junos 19.2R1.8 #1247" by making PEM naming consistent #1248
• [IOS] Fix get_optics metric #1220
• [IOS] Allow username detection on older Cisco ios versions #1121

3.0.1

Changes

Release 3.0.0 introduced support for the Arista FN 0039 command changes (#1093), by replacing the old style commands with the new style commands. This also affected the way NAPALM loads the configuration on the device (i.e., it would transform your configuration before loading). In order to prevent this, and avoid unexpected results, we introduced a new optional argument eos_fn0039_config, defaulting to False, which you can use to select whether you want NAPALM to convert the configuration command before loading. By default, NAPALM won't transform your configuration, but setting eos_fn0039_config to True it would help you transition to newer EOS versions.

Bug Fixes

• [Junos] close configuration in case configure_private is set to avoid configure session to stay forever #1199
• [IOS] get_interfaces_counters broken with Managment Interface #1201
• [IOS] get_optics does not work on VSS setup #1208
• [IOS] get_optics broken if input value is N/A #1206
• [NXOS] Fix cmd_verify and null character #1214
