# Opening the QoS UBP/Traffic Profile dialog box

When you assign a filter name to a VLAN (for example, redFilter), the switch automatically creates all the necessary QoS classifiers with the name you assigned (in this case, redFilter) if that filter does not already exist.

Traffic Profile applies the QoS policy on port(s) that you specify. UBP applies the QoS policy when a user is authenticated by EAPOL or non-EAPOL.

If you had previously defined the filter, then that preexistent filter is used. After a filter is created (either by you or automatically by the switch), it can be modified (that is, entries can be deleted or added) on the QoS UBP/Traffic Profile dialog box.

CAUTION

If you define multiple meters that 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.

Use this procedure to open the QoS UBP/Traffic Profile dialog box.

## Procedure steps

1. In the navigation pane, double-click QoS.
