System and method for pinning virtual machine adapters to physical adapters in a network environment

Logic encoded in non-transitory media that includes instructions for execution and when executed by a processor, is operable to perform operations comprising:

• capturing a first BPDU from a first switch in a VLAN, and a second BPDU from a second switch in the VLAN;
• identifying a first root bridge ID of a first spanning tree associated with the first BPDU and a second root bridge ID of a second spanning tree associated with the second BPDU;
• comparing the first root bridge ID and the second root bridge ID;
• and
• communicating an alert, wherein if the first root bridge ID is different from the second root bridge ID, the alert indicates pinning a vNIC associated with a VM on a server from a first pNIC on the server, to a second pNIC.

An apparatus, comprising:

• a snooping module;
• a memory element for storing data;
• and
• a processor operable to execute instructions associated with the data, wherein the snooping module, the processor, and the memory element cooperate such that the apparatus is configured for:
• capturing a first BPDU from a first switch in a VLAN, and a second BPDU from a second switch in the VLAN;
• identifying a first root bridge ID of a first spanning tree associated with the first BPDU and a second root bridge ID of a second spanning tree associated with the second BPDU;
• comparing the first root bridge ID and the second root bridge ID;
• and
• communicating an alert, wherein if the first root bridge ID is different from the second root bridge ID, the alert indicates re-pinning a vNIC associated with a VM from a first pNIC on the apparatus, to a second pNIC.
