Hi NETMOD WG, Scott and I think that we have finished updating these two drafts based on WGLC comments. I.e., we are finally done, we hope!
The diff for draft-ietf-netmod-sub-intf-vlan-model is pretty minor/boring, but is here: https://author-tools.ietf.org/iddiff?url1=draft-ietf-netmod-sub-intf-vlan-model-11&url2=draft-ietf-netmod-sub-intf-vlan-model-13&difftype=--html The diff for draft-ietf-netmod-intf-ext-yang is here: https://author-tools.ietf.org/iddiff?url1=draft-ietf-netmod-intf-ext-yang-14&url2=draft-ietf-netmod-intf-ext-yang-15&difftype=--html The second draft has a few more significant changes (increasing the doc size by 8 pages), that I would like to draw the WG’s attention to: (1) in-discard-overflows has moved so that it augments all interfaces, rather than being restricted to Ethernet interfaces. (2) As requested, I have defined a set of Ethernet ingress/egress histogram counters (i.e., measuring the number of packets based on their length). IEEE 802.3 effectively only really recognises frames up about 1518/1522 bytes, but often hardware supports Jumbo frames, up to around 8/9K. Hence, I’ve defined counters that match those previously defined by the RMON MIB but extended them with a few extra buckets to account for larger frames (e.g., 1519-to-2047, 2048-to-4095, 4096-to-8191, 8192-to-max. Not all hardware will support these initially, but deviations and extra vendor defined counters can be used for those cases, and hopefully, over time, newer hardware will align to support these definitions directly. (3) I’ve removed the sub-interface and ethSubInterface identities that were intended to abstract over the IANA if:types for augmented data nodes, but the solution didn’t really work helpfully as it is defined. This might still be worth trying to fix in future but would need to be done as a set of base identities that the IANA types derive from rather than the other way around. I.e., a bigger item of work beyond the scope of this draft, so if we want to progress this idea, this would be best done in an entirely separate draft. I’m fairly sure that the chairs would like these drafts to be done and handed off to the AD, so please take a look and comment back to the list if you have any issues with the approach taken on either of these changes. Kind regards, Rob
