Abstract:
1. A method executed by a processor associated with a server in a network environment, comprising: 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, wherein if the first root bridge ID is different from the second root bridge ID, the alert indicates pinning a virtual network interface card (vNIC) associated with a virtual machine (VM) on a server from a first physical network interface card (pNIC) on the server, to a second pNIC.
