Hi Matt, Hi Ole, I think adding a cli & api call for renaming interfaces would be quite useful. I agree we shouldn't refer to interfaces by name in the API thought (sw_if_index is definitely the way to go)
Several non-api use-cases would imho benefit from this. I can see writing cli scripts without having to sed $interface_name all over the place. Also towards user friendliness, when exposing vppctl in a production environment, `show interface` can be a bit hard to understand and could benefit from context-related names. Anyway, would definitely use such a feature :) Cheers -Nathan Le mer. 5 mai 2021 à 10:18, Ole Troan <otr...@employees.org> a écrit : > Matt, > > > Source file src/vnet/interface.c has a function vnet_rename_interface(). > It only appears to be called by the lisp plugin currently.
