Abstract: A method for pinning virtual machine adapters to physical adapters in a network environment is provided and includes capturing a first Bridge Protocol Data Unit (BPDU) from a first switch in a virtual local area network (VLAN), and a second BPDU from a second switch in the VLAN, identifying a first root bridge identifier (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. If the first root bridge ID is different from the second root bridge ID, the alert indicates re-pinning a virtual network interface card associated with a virtual machine from a first physical network interface card (pNIC) on the to a second pNIC.
