🟡 Changes recommended

The EOS netmiko_error_regexp pattern as added is likely to miss configuration errors due to use of a start-of-string anchor without multiline matching.

Pull request overview

This PR adds Netmiko-based configuration support for Arista EOS devices (vEOS/cEOS) by extending device defaults, enabling netlab_config_mode: netmiko, and documenting the new configuration method and caveats.

Changes:

  • Add EOS Netmiko defaults (netmiko_device_type, netmiko_error_regexp) and advertise netmiko as a supported netlab_config_mode for EOS (with sh still available for cEOS).
  • Update EOS normalization template to apply the relevant interface knob when using netmiko as well as sh.
  • Update platform documentation and caveats to link to vEOS/cEOS-specific EOS caveats and mention Netmiko configuration mode.
