Defining CoS Code-Point Aliases (J-Web Procedure)
To define CoS Value Aliases, select Configure
> Class of Service > CoS Value Aliases in the J-Web interface.
Table 1 describes the related fields. By defining
aliases you can assign meaningful names to a particular set of bit
values and refer to them when configuring CoS components.

DSCP
|
Allows you to define aliases for DiffServ
code point (DSCP) IPv4 values.
You can refer to these aliases when you configure classes and
define classifiers.
|
Click DSCP.
|
IPv4 Precedence
|
Allows you to define aliases for IPv4 precedence
values.
Precedence values are modified in the IPv4 type-of-service (TOS)
field and mapped to values that correspond to levels of service.
|
Click IPv4 Precedence.
|
Alias Name
|
Displays names given to CoS values—for
example, af11 or be.
|
None.
|
Default Value
|
Displays the default values mapped to standard
aliases. For example, ef (expedited forwarding) is a standard
alias for DSCP bits 101110.
You cannot delete default values. The check box next to these
values is unavailable.
|
None.
|
Configured Value
|
Displays the CoS values that you have assigned
to specific aliases.
You can delete a configured alias.
|
None.
|
Add
|
Opens a page that allows you to define CoS
value aliases.
|
Click Add.
|
Delete
|
Allows you to delete a configured CoS value
alias.
You cannot delete a default alias.
|
Select the check box next to the CoS value
alias and click Delete.

a CoS Value Alias
|
CoS Value Alias
|
Assigns a name to a CoS value. A CoS value
can be of different types—DSCP or IP precedence.
|
To define an alias for a CoS value, type a
name—for example, my1.
|
CoS Value Alias Bits
|
Specifies the CoS value for which an alias
is defined.
Changing this value alters the behavior of all classifiers that
refer to this alias.
|
To specify a CoS value, type it in an appropriate
format:
- For DSCP CoS values, use the format xxxxxx, where x is
1 or 0—for example, 101110.
- For IP precedence CoS values, use the format xxx, where
x is 1 or 0—for example, 111.
