CoS IRL Reference Mapping Table

The CoS IRL reference table uses 32 indexes or virtual rate limiters, and maps each virtual limiter to a physical limiter or resource. An IRL reference table exists for each port group configured, and is indexed similarly to port-resources, as port-group.port-type reference. Because it is an optional configuration, IRL references are not populated with limiters (resources), but can be configured by you. The IRL reference table can be displayed using the show cos reference irl command.

The following example displays default values for the show cos reference irl command output:

System(rw)->show cos reference irl
Group Index Reference Type Rate Limiter
----------- --------- ---- ------------
0.0         0         irl  none
0.0         1         irl  none
0.0         2         irl  none
0.0         3         irl  none
0.0         4         irl  none
0.0         5         irl  none
0.0         6         irl  none
0.0         7         irl  none
0.0         8         irl  none

Physical-Limiter to reference mapping can be configured using the set cos reference irl command. The other references not configured are indicated by rate limiter “none”. To configure a physical limiter to reference mapping, you need to:
