Re: [Netconf] Solicit comments on inline action capability for NETCONF

[Robert Wilton <[e-mail]>]

Hi Qin,

Having read this draft, I can understand what the draft is proposing, 
but I don't currently understand why this is useful. Specifically, I 
don't find the example that is in the draft as compelling.  If the 
desire is to set the MTU and enable the interface as one configuration 
operation, then wouldn't the client just configure both mtu and enabled 
leaves at the same time.  Why is a separate action required here to 
enable the interface?

So I'm struggling to think of actions that apply to configuration 
datastores where the same behaviour cannot just be achieved via a simple 
configuration manipulation.  One use case could be wanting to repeat the 
same configuration on many interfaces at the same time, but for this, I 
think that a configuration templating solution would be preferable 
rather than using actions, and a templating would probably just reused 
edit-config/edit-data.  So, if you have some other more concrete 
examples of actions that apply to configuration datastores, that might 
be helpful.

Another question (which I think is similar to the one that Eric has also 
asked) is whether to have transactions that mix configuration operations 
and action operations on <operational>.  E.g. perhaps enable an 
interface and reset the counters at the same time, or perform some 
config change and establish a dynamic subscription at the same time.  
But I question how robust this would end up being (I'm not generally a 
fan of distributed transactions - they never seem to be as robust as 
they claim to be).  Perhaps one for future thought and discussion.

Thanks,
Rob
