Subject: [I2rs-proto-dt] I2RS meeting

 

Hi,

 

I plan to listen in to the I2RS meeting.

It's probably too late for a conf-call before the meeting,

but I am available.

 

I think it is OK to say the YANG constraints apply to

the derived "intended config" and also apply

to the running datastore as defined in YANG.

 

That means if the max-entries is 5, then 5 can exist in

the running config, and new entries added to ephemeral

must override entries in running.  Retrieving the intended config

actually used (e.g., which config entry is disabled) is

a different issue.  The intended config can only have 5 entries

in it.  It falls out that the ephemeral datastore can only

have 5 entries in it as well.

 

Not all YANG constraints are as easy as min-elements,

and max-elements.

 

mandatory, must, when, and unique need more careful thought

 

 

Andy
