Hi Juergen,

Thanks for the clarity. I somewhat agree. Different lifetime shouldn't really cause any impact.

One nit,

When I pull out a configured interface, the operational state of this
interface is gone but not the config - if I put the interface back, it
should come up configured as before.

Depends. If LC itself is removed, then all the related interfaces would be removed from the running-config. And reinserting the LC may not bring their individual conf back (ignoring the notifications).

Obviously, I can also have
operational state of an interface that has not been configured yet.

Yes.

Cheers,

Hmm..Could you please clarify the above a bit more?


The classic example:

interface is gone but not the config - if I put the interface back, it
should come up configured as before. Obviously, I can also have
operational state of an interface that has not been configured yet.
