Solution

This patch updates the esx-base VIB to resolve an issue that occurs when you enable BPDU (Bridge Protocol Data Unit) guard on the physical switch port. The BPDU frames sent from the bridged virtual NIC cause the physical uplink to get disabled and as a result, the uplink goes down.

Note: Identify the host which sent out the BPDU packets and set esxcfg-advcfg -s 1 /Net/BlockGuestBPDU on that host. This filters out and blocks BPDU packets from the Guest. The virtual machines with the bridged virtual NICs should be powered on only after this filter is turned on for the filter to take effect.

Patch Download and Installation

The typical way to apply patches to ESXi hosts is through the VMware Update Manager. For details, see the Installing and Administering VMware vSphere Update Manager.
