00:12MAC Example (MAC-FD #5)@Andreas Lattoch

Discussion about VLAN-ID

  * Where is the VLAN-ID related to "learned-mac-address" configured?

    * Within the device (VLAN-FC)?

    * out side of the Device - learned VLAN-ID together with learned mac address at ingress port (incoming)?

Input for Andreas

  • switch config with and without VLAN-ID-Filtering
    • without with VLAN-ID-Filtering (MAC bridge only) 
      • VLAN-ID equals to zero is displayed (at least for one vendor)
    • in case of with VLAN-ID-Filtering (VLAN bridging domain enabled) 
      • in this case case the VLAN-ID must be configured at the device.

Proposal made for 29th of September.




@Alexander Wenk


Questions during the conversion to yang.

Remaining question: How to add a clock to the CoreModel?

  • CoreModel unpruned to YANG
    • clock reference in yang is from ltp:embedded-clock only (which must be a reference)

AI Martin: Check with ISSOMI an OTIM about usage of processing construct...

AI Martin: Check with Prathiba

Sketch by Thorsten:


looking for experts


Relation between planning and actual data from the network

  • planning identifiers <-??-> network managed object identifiers
  • detailed problem description??
  • link-id into LTP - vs - handling on controller/app level - based on inventory infos - how to address the right air-interface if only the polarization is different - which cannot be remotely configured → cabling matters.

Mediator Instance Manager

    • Working Assumption:  not decided
    • SIAE would like to decide based on efforts after analysis. 
    • UML include the "service" - but not the operational and maintenance layer
    • YAML (OpenAPI3) → UML (papyrus) → YANG →
