Hyper-V feature restrictions

This section describes the following restricted vRouter features that do not function or require specific Hyper-V configuration in the Hyper-V environment.

Restricted features include:
  • LACP does not work on Hyper-V

  • VRRP in RFC-Compliant mode

    Currently, no Hyper-V settings allow RFC-compliant MAC address behavior for VRRP interfaces. To prevent RFC compatibility issues when running a vRouter on a Hyper-V platform, by default, RFC-compliant MAC address behavior is not enabled on the vRouter.

  • Port Mirroring (SPAN, RSPAN, ERSPAN)

    Hyper-V must have MAC address spoofing enabled for Port Mirroring to work.

VRRP in RFC-Compliant mode

vRouter features that do not work in the Hyper-V environment include the behavior of RFC-compliant MAC addresses for VRRP interfaces.

The default behavior of non-RFC-compliant MAC addresses is required for any deployment in which Hyper-V provides Layer 2 services, because it appears that Hyper-V does not support delivery of multicast packets sent from a virtual MAC. For more information, refer to Hyper-V documentation.

Port Mirroring (SPAN, RSPAN, ERSPAN)

Regardless of the flavor used, the vRouter replicates traffic to the destination interface from a multitude of MAC addresses from which the traffic was originally received. Hyper-V blocks all such traffic unless a Hyper-V feature called MAC Spoofing is enabled. For more information, refer to Hyper-V documentation.

A Google search of hyper-v mac spoofing yields good results.
