Configuring the Switch Modules using the Menu-driven Interface 
Setting Class of Service 
To configure Class of Service: 
1. Highlight Configure Class of Service on the Configure Class of Service, Default 
Priority, and Traffic Class menu. 
2. Press the Enter key. The following screen is displayed. 
 
This screen allows you to set the following features: 
—  Max. Packets—The Class of Service scheduling algorithm starts from the highest 
CoS for a given port, sends the maximum number of packets, then moves on to the 
next lower CoS. Values from 0 to 255 can be entered in this field. Entering zero 
instructs the switch module to continue processing packets until there are no more 
packets in the CoS transaction queue. 
—  Max. Latency—The maximum latency is the maximum allowable time a packet 
stays in the CoS queue. The packets in this queue are not delayed more than the 
amount entered in this field. The timer is disabled when this field is set to zero. Each 
unit of this timer is equal to 16 microseconds. 
3.  After making your changes, highlight APPLY and then press the Enter key. 
 
IMPORTANT:  To save the configuration settings permanently, you must enter them into NVRAM 
using the Save Changes option on the main menu. Refer to the “Saving Changes” section earlier 
in this chapter.
