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).
C3(su)->set cos port-resource irl 1.0 1 unit kbps rate 512
C3(su)->set cos port-resource irl 2.0 1 unit kbps rate 10000
C3(su)->show cos port-resource irl 1.0 1
Group Index Resource Type Unit Rate Rate Limit Type Action
----------- -------- ---- ---- ---------- --------------- ------
1.0 1 irl kbps 512 drop none
C3(su)->show cos port-resource irl 2.0 1
Group Index Resource Type Unit Rate Rate Limit Type Action

2.0 1 irl kbps 10000 drop none
3. In the CoS IRL reference mapping table for each port group, create a reference for each IRL
resource created in the previous step. We will use reference number 1.
C3(su)->set cos reference irl 1.0 1 rate-limit 1
C3(su)->set cos reference irl 2.0 1 rate-limit 1
C3(su)->show cos reference irl 1.0
Group Index Reference Type Rate Limiter
----------- --------- ---- ------------
1.0 0 irl none
1.0 1 irl 1
1.0 2 irl none
1.0 3 irl none
...
1.0 97 irl none
1.0 98 irl none
1.0 99 irl none
C3(su)->show cos reference irl 2.0
Group Index Reference Type Rate Limiter
----------- --------- ---- ------------
2.0 0 irl none
