● To view the ECN markings on an interface, use the show queuing statistics interface interface-name
wred command:
OS10# show queuing statistics interface ethernet 1/1/1 wred
● To view any egress packet loss, use the show queuing statistics command:

RoCE for VXLAN over VLT
OS10 supports RoCE for VXLAN in a VLT setup. Configuring RoCE with VXLAN is similar to configuring RoCE without VXLAN.
When you configure VXLAN and span that across a VLT topology, apply the configuration on all interfaces across the VLT
topology where you want to support RoCE.
For more information about how to configure RoCE, see the Configure RoCE on the switch section.
Sample configuration of RoCE for VXLAN over VLT
The following describes a topology where RoCE is enabled with VXLAN over VLT. SW1 is configured as VTEP1 and is the
upstream switch that connects to the outer network. VLT peer 1 and VLT peer 2 form a VLT topology and are also configured as
VTEP 2. A top-of-rack (ToR) switch is connected to the VLT peers through a VLT port channel. The ToR is the downstream
switch for end devices, such as, virtual machines.
