2. Create a traffic behavior and
enter traffic behavior view.

3. Configure a mirroring action
for the traffic behavior.
• Mirror traffic to an interface:
mirror-to interface
interface-type
interface-number
[ destination-ip
destination-ip-address
source-ip source-ip-address
[ dscp dscp-value | vlan

• Mirror traffic to a CPU:
By default, no mirroring action is
configured for a traffic behavior.
When the destination IP address
is specified for mirrored packets,
the output interface of the route to
the destination address does not
support ECMP.

Applying a QoS policy
Applying a QoS policy to an interface
By applying a QoS policy to an interface, you can mirror the traffic in the specified direction on the
interface. A policy can be applied to multiple interfaces, but in one direction (inbound or outbound) of
an interface, only one policy can be applied.
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.
