Multiple mobility domains with VLAN translation in a multi-tenant network environment

Non-transitory tangible media that includes instructions for execution, which when executed by a processor, is operable to perform operations comprising:

• 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 same original VLAN falls within a pre-configured VLAN range;
• and
• if the same original VLAN falls within the 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 same original VLAN into the first VLAN and the second VLAN according to the respective mobility domains for per-port VLAN significance;
• if the same original VLAN does not fall within the preconfigured VLAN translation range,
• instantiating virtual ports corresponding to the same original VLAN on substantially all ports of the network element, and
• broadcasting traffic on the same original VLAN to substantially all the virtual ports.

An apparatus, comprising:

• a memory element for storing data;
• and
• a processor, wherein the processor executes instructions associated with the data, wherein the processor and the memory element cooperate, such that the apparatus is configured for:
• 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 same original VLAN falls within a pre-configured VLAN range;
• and
• if the same original VLAN falls within the 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 same original VLAN into the first VLAN and the second VLAN according to the respective mobility domains for per-port VLAN significance;
• if the same original VLAN does not fall within the preconfigured VLAN translation range,
• instantiating virtual ports corresponding to the same original VLAN on all ports of the network element, and
• broadcasting traffic on the same original VLAN to all the virtual ports.
