    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 facilitating multiple mobility domains with VLAN translation in a multi-tenant network environment is provided and includes detecting attachment of a first virtual machine on a first port and a second virtual machine on a second port of a network element, the first port and the second port being configured with a first mobility domain and a second mobility domain, respectively, and the first and second virtual machines being configured on a same original VLAN, determining whether the original VLAN falls within a pre-configured VLAN range, translating the original VLAN to a first VLAN on the first port corresponding to the first mobility domain and to a second VLAN on the second port corresponding to the second mobility domain, and segregating traffic on the original VLAN into the first VLAN and the second VLAN according to the respective mobility domains for per-port VLAN significance.
