For example, if the frame is an untagged IP Ethernet frame, a match will not be found until the third priority level
(DSCP). The CoS and Color values defined for the frame’s DSCP value will be applied to the frame.
You can disable some of these classification methods by configuring them as un-trusted. For example, if 802.1p
classification is configured as un-trusted for a specific interface, the classification mechanism does not perform
classification by UP bits. This is useful, for example, if classification is based on DSCP priority bits.
If no match is found at the logical interface level, the default CoS is applied to incoming frames at this level. In this
case, the Color of the frame is assumed to be Green.
Configuring Ingress Path Classification on a Logical Interface
This section explains how to configure the classification criteria per each logical interface. The following sections
explain how to modify the classification tables per bit type.
To configure the classification criteria for a logical interface:
1. Select Ethernet > Interfaces > Logical Interfaces . The Logical Interfaces page opens.
Figure 214 Logical Interfaces Page
2. Select the interface you want to configure and click Edit . The Logical Interfaces - Edit page opens.
