When you configure classes and define classifiers, you can refer to the markers by alias names. You can configure user-defined classifiers in terms of alias names. If the value of an alias changes, it alters the behavior of any classifier that references it.
To define a code-point alias on an SRX-series device, include the code-point-aliases statement at the [edit class-of-service] hierarchy level:
- [edit class-of-service]
- code-point-aliases {
- (dscp |exp | ieee-802.1 | inet-precedence) {
- alias-name bits;
- }
- }
The CoS marker types are as follows:
For example, you can set up the following configuration:
- [edit class-of-service]
- code-point-aliases {
-
- dscp {
-
- my1 110001;
- my2 101110;
-
- be 000001;
- cs7 110000;
- }
- }
The sample configuration produces this mapping:
user@host>show class-of-service code-point-aliases
dscp
Alias Bit pattern ef/my2 101110 af11 001010 af12 001100 af13 001110 af21 010010 af22 010100 af23 010110 af31 011010 af32 011100 af33 011110 af41 100010 af42 100100 af43 100110 be 000001 cs1 001000 cs2 010000 cs3 011000 cs4 100000 cs5 101000 nc1/cs6/cs7 110000 nc2 111000 my1 110001
