Table 142: Code Point Alias Configuration Page

Field	Function
Alias name	Displays the name given to CoS values. For example, af11 or be.
Alias type	Displays the code point type. The following types of code points are supported: DSCP—Defines aliases for Differentiated Services code point (DSCP) for IPv4 values. You can refer to these aliases when you configure classes and define classifiers. DSCP-IPv6—Defines aliases for DSCP IPv6 values. You can refer to these aliases when you configure classes and define classifiers. EXP—Defines aliases for MPLS experimental (EXP) bits. You can map MPLS EXP bits to the device forwarding classes. inet-precedence—Defines aliases for IPv4 precedence values. Precedence values are modified in the IPv4 TOS field and mapped to values that correspond to levels of service.
CoS Value bits	Displays the CoS value for which an alias is defined. Note: Changing this value alters the behavior of all classifiers that refer to this alias.
