Procedure 9-2 User-Defined CoS Configuration
Step Task Command(s)
1. Enable CoS set cos state
2. Create CoS port groups set cos port-config
3. Define physical rate limiters for groups set cos port-resource
4. Create virtual reference for the IRL resource
(physical reference) for each port group
set cos reference
5. Add IRL reference to CoS settings table set cos settings
