[Engine-devel] Network labeling requirements follow up questions

[Malini Rao]

[top posting] 

Based on your responses then, we need to tweak Eldan's sketch  - see attached. 

Here, you will see I have two tabs on the right - Unassigned networks and Labels. Unassigned networks will list individual networks that have not been assigned either manually or as part of a label. If a network has been assigned to a NIC as apart of a label, it will still show up on the unassigned networks list but if the user tries to assign that network to that same NIC, then the UI will not allow that and a message will pop-up stating '<Network Name> is already assigned to this NIC". Does this make sense? Or do we allow network sharing only via Bonding? I.e, if NIC 1 is assigned Label1 ( Blue, yellow, Green) and I want to assign NIC2 to Blue only, would I drag Blue from unassigned networks ( even t hoguh blue is assigned via label 1 to another NIC) or do I drag NIC 2 to NIC 1 and create a bond which presents me an option to use all 3 or select from the list of networks attached to NIC1?

Going back to my mockup, you will also see an attachment for the unassigned Labels tab where you see the labels, the networks associated with them so that you don't have to drag it to the left in order to see what networks live in that label. I have retained Eldan's Manage labels action link too.

Let me know if this makes sense.

Thanks
Malini

yes

label is just a tool to ease network provisioning on the host, you can
always use 'manual' actions to provision the networks.

Hope that clarifies, I'll be happy to answer more questions if you have any.
