Does the VDX8770 with NOS 4.1.2 support PBR on a ve interface

I have set this up similar to an MLX and it does not seem to be working. The config guide doesn't specifically say whether it works on ve inetrfaces or not

Policy-based Routing (PBR)


This feature is NOT supported on VDX6710/20/30.


If a PBR route-map is applied to an PHYSICAL interface that is actively participating in a control protocol and the ACL specified in the route-map also matches the control protocol traffic the control protocol traffic will be trapped to the local processor and not be forwarded according to the route-map.


Policy-based Routing (or PBR) is a technique to make routing decisions based on policies configured by a network administrator. PBR configuration is done by using a combination of IP ACLs and route maps. The VDX platform programs the ACLs on the interfaces and routes traffic that matches the ACLs according to instructions in the route map entry.


PBR can be configured based on Layer 3 and Layer 4 information and the VDX platform can be instructed to forward packets to a pre-determined next-hop gateway or drop the packet.


PBR is supported on VDX 8770 and VDX 6740x.
