CUSP YANG Data model Through Im • The YANG data model through Management Interface for BNG-UP includes: BNG-UP Port, Control interface parameters, service interface parameters, ACL and Qo. S, etc. BNG-UP port Control interface parameters Data Model through Im Service interface parameters ACL (Augment ietf-netmod-acl-model) Qo. S (Augment asechoud-rtgwg-qos-model) IETF 101 Rtgwg London 3

BNG-UP Port Configuration • BNG-CP configures BNG-UP port parameters information through the management interface by Netconf protocol IETF 101 Rtgwg London 4

Configure Service Interface Parameters • Vx. LAN/Vx. LAN-GPE protocol is used for the service interface. • The Vx. LAN tunnel parameters are configured through management interface for BNG-UP. IETF 101 Rtgwg London 5

Configure Control Interface Parameters • The Open. Flow protocol parameters are configured through management interface for BNG-UP. IETF 101 Rtgwg London 6

Security Consideration and IANA Updated ØThe Security and IANA consideration section is updated based on T. Petch’s comments(Thanks, ^_^). ØRich the Security consideration based on https: //trac. ietf. org/trac/ops/wiki/yang-security-guidelines. ØAdd the IANA consideration part to register the vbng yang model. IETF 101 Rtgwg London 9

Next Steps: Ø More comments for CUSP YANG data model? Ø Continue to rich the document based on comments and implementation IETF 101 Rtgwg London 10

Thank you IETF 101 Rtgwg London 11
