    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.

    Abstract: The present technology provides a system, method and computer-readable medium for configuration pattern recognition and inference, directed to a device with an existing configuration, through an extensible policy framework. The policy framework uses a mixture of python template logic and CLI micro-templates as a mask to infer the intent behind an existing device configuration in a bottom-up learning inference process. Unique values for device/network identifiers and addresses as well as other resources are extracted and accounted for. The consistency of devices within the fabric is checked based on the specific policies built into the extensible framework definition. Any inconsistencies found are flagged for user correction or automatically remedied by a network controller. This dynamic configuration pattern recognition ability allows a fabric to grow without being destroyed and re-created, thus new devices with existing configurations may be added and automatically configured to grow a Brownfield fabric.

    Abstract: A switch/switching fabric is configured to load balance traffic. The switch fabric includes a plurality of switches. A packet is received at a first switch of the plurality of switches. The first switch load balances the packet to a particular entity among a plurality of entities. Each of the entities is connected to one of the plurality of switches. The first switch determines a particular switch of the plurality of switches to which the packet should be directed, the particular entity being connected to the particular switch of the plurality of switches. The particular switch receives the packet, and determines which interface of the particular switch to direct the packet to the particular entity. The plurality of entities include servers and network appliances as physical devices or virtual machines.
