DiffServ Configuration Examples
Typically, you would use the Diffserv command set to complete configuration tasks in the
following order:
1. Enable DiffServ.
2. Create a Class.
3. Create one or more classification rules within the Class.
4. Create a Policy.
5. Add one or more Classes to the Policy.
6. Add Policing (Conforming/Non‐conforming, Drop/Forward, Rate Limit, Precedence/DSCP
Rewrite) actions or just Marking (Precedence/DSCP Rewrite) actions to the Policy.
7. Assign the Policy to one or more ports.
The following examples show how to proceed through these tasks to create DiffServ policies.
This example creates two separate policies:
a. policyef — rate‐limits ingressed traffic on port fe.1.1 to a maximum of 100Mb/s, and on
the same traffi,c also rewrites the six DSCP bits to a decimal value of 46 for Express
Forwarding on layer 3.
b. policyaf31 — rate‐limits ingressed traffic on port fe.1.2 to a maximum of 100Mb/s, and on
the same traffic, also rewrites the six DSCP bits to a decimal value of 26 for Flash
forwarding on layer 3.

D2(rw)->set diffserv service add in fe.1.2 policyaf31
This example creates one policy which identifies VOIP traffic (DSCP value 46 or 32) on ports ge.1.1
through ge.1.10, and drops all other traffic.
