QoS Limitations for VXLAN Implementations with Nexus Equipment
Deploying EVPN solutions on Cisco's Nexus line of networking equipment is a common practice. EVPN can be used in conjunction with VXLAN – a popular method of connecting multiple datacenters over layer 3 of the OSI networking model. VXLAN has gained popularity due to its ability to further segment large networks into more VLANs than what a traditional VLAN would allow. QoS (quality of service) is another common implementation on these networks, too, but there are a couple of considerations that network engineers must acknowledge while trying to implement QoS on top of EVPN/VXLAN implementations.
First, QoS classification is not supported on VXLAN traffic to access direction on layer 3 interfaces. Special care will need to be taken to work around this. Cisco has more documentation available on how to work with QoS regarding these circumstances for the NX-OS. Likewise, QoS buffer-boost is not applicable for VXLAN traffic, so network engineers need to keep that in mind as well.
