# Adding QoS policies

Use this procedure to add QoS policies.

CAUTION

When you define multiple meters that may match the same traffic, you must specify the in-profile and out-of-profile traffic as drop or pass to ensure that the traffic is processed at the prescribed rate. If you do not do this, each meter processes the traffic, and this interaction can cause traffic to be treated in unexpected ways.

## Procedure steps

1. From the navigation tree, double-click QoS.

2. From the QoS tree, double-click QoS.

3. Select the Policy tab.

4. Click Insert.

   The Insert QoS Policy screen opens.

5. Enter the information to use for this QoS policy.

6. Click Insert.

   Note

   The InterfaceRoles and InterfaceIndex fields are mutually exclusive. When the InterfaceIndex field is not zero, the InterfaceRoles must be empty (select none when inserting the policy). When the InterfaceRoles specifies a valid role combination, the InterfaceIndex field must be 0.
