Applying a QoS policy to an interface
By applying a QoS policy to an interface, you can mirror the traffic in the specified direction of the interface. A policy can be applied to multiple interfaces. In one direction (inbound or outbound) of an interface, only one policy can be applied.
In a VXLAN network, the type of traffic that can be mirrored in the outbound direction of an interface depends on the VXLAN hardware resource allocation mode of the device:
If the Layer 2 or Layer 3 gateway mode is used, only the underlay traffic can be mirrored.
If the border mode is used, neither the underlay nor the overlay traffic can be mirrored.
To apply a QoS policy to the outbound traffic of an interface, make sure the traffic behavior used by the policy contains only traffic mirroring actions. If non-traffic-mirroring actions are configured, all actions configured in the traffic behavior become invalid.
The device does not support mirroring outbound traffic of aggregate interfaces.
To apply a QoS policy to an interface:
Step | Command |
