Error: "frame-overhead cannot be defined in policy bound to a VIF"


You tried to configure a frame overhead on a QoS policy that is attached to a VIF interface. This is not allowed.

Configuration of frame overhead is on a port-wide basis. To attach a QoS policy to a VIF interface, you must have a QoS policy attached to the trunk interface — the physical interface that the VIF belongs to.

You will trigger this error if you combine commands like these:

set policy qos name <policy-name> shaper frame-overhead <value>
set interfaces dataplane <interface-name> vif <vif-id> policy qos <policy-name>


If you want to adjust the frame overhead you must configure it on the policy that is attached to the trunk interface.
