Configuring Policy Class of Service (CoS)
9-16 Policy Classification Configuration
enabled, the default and user‐assigned policy‐based settings will override port‐based settings
described in
Chapter 10 .
About Policy-Based CoS Configurations
Once enabled using the set cos state command as described in “ set cos state ” on page 9‐18, you
can add to the policy‐based CoS function by defining new port groupings, and assigning inbound
rate limiters. The process for user‐defined CoS configuration involves the following steps and
associated commands listed in
Procedure 9‐2 . An example follows the procedure.
Example
This example creates different inbound rate limiters for two port groups and then assigns them to
traffic with a CoS setting of 0.
1. Configure two port groups, one for user ports and one for uplink ports and assign ports to the
groups. Port group 1.0 will represent user ports, group 2.0 will represent uplink ports.
D2(su)->set cos port-config irl 1.0 name Users ports ge.1.1-46
D2(su)->set cos port-config irl 2.0 name Uplink ports ge.1.47-48
D2(su)->show cos port-config
Inbound Rate Limiting Port Configuration Entries
----------------------------------------------------------------------
Port Group Name :Default
Port Group :0
Port Type :0
Assigned Ports :none
----------------------------------------------------------------------
Port Group Name :Users
Port Group :1
Port Type :0
Assigned Ports :ge.1.1-46
----------------------------------------------------------------------
Port Group Name :Uplink
Port Group :2
Port Type :0
Assigned Ports :ge.1.47-48
----------------------------------------------------------------------
2. Configure physical inbound rate limiters for each port group. For the user port group (1.0),
create an IRL (irl‐index of 1) for 512 kbps. For the uplink port group (2.0), create an IRL (irl‐
index of 1) for 10 megabits per second (10,000 kbps).
D2(su)->set cos port-resource irl 1.0 1 unit kbps rate 512
D2(su)->set cos port-resource irl 2.0 1 unit kbps rate 10000
