What I did

Implemented CLI for Fast-linkup feature including:

  • config feature parameters
  • enable/disable the feature per-port
  • show feature parameters
  • show interfaces feature status

How I did it

  • By adding the new command support to config and show CLI

How to verify it

  • Run Fast-linkup CLIs

Which release branch to backport (provide reason below if selected)

  • 202511

New command output (if the output of a command-line utility has changed)
