Abstract: In accordance with one example embodiment, there is provided a system configured for virtual local area network (VLAN) blocking on a virtual port channel (vPC) member link to handle discrepant virtual network instance (VNI) to VLAN mappings. In other embodiments, the system can be configured for providing Virtual Switch Interface Discovery Protocol (VDP) and virtual switch enhancements to accommodate discrepant VNI to VLAN mappings. In another example embodiment, an apparatus is provided that includes a processor, and a memory coupled to the processor, where the apparatus is configured such that if a server is connected through a virtual port channel, a VDP is used to notify the server of different VNI to VLAN mappings. In another embodiment, the apparatus can extend a VDP Filter Info Field to carry a set of VLANs mapped to a VNI, keyed by leaf MAC addresses that serve as bridge identifiers.

Abstract: An example method for touchless multi-domain VLAN based orchestration in a network environment is provided and includes receiving mobility domain information for a virtual machine associated with a processor executing the method in a network environment, the mobility domain information comprising a mobility domain identifier (ID) indicating a scope within which the virtual machine can be moved between servers, generating a virtual station interface (VSI) discovery protocol (VDP) message in a type-length-value (TLV) format with the mobility domain information, and transmitting the VDP message to a leaf switch directly attached to the server, wherein the leaf switch provisions a port according to the mobility domain information.

Abstract: A method is described and in one embodiment includes receiving at a top-of-rack (“TOR”) switch a notification concerning a virtual machine (“VM”), wherein the received notification identifies a host associated with the VM; determining whether the identified host is directly connected to the TOR switch; and if the identified host is not directly connected to the TOR switch, identifying an intermediate switch to which the identified host is directly connected; and determining whether the identified intermediate switch to which the identified host is directly attached is attached to the TOR switch.
