Configuring Type of Service

Typically, this feature determines the packet delivery prioritization for low-delay, high-throughput, highly reliable service, or normal service for NetFlow traffic. On all Flow packets, Type of Service byte is represented as Differentiated Service Code Point (DSCP) and Explicit Congestion Notification.

1. Click Console Integrations () in the navigation bar, and select Type of Services under System Configuration.

Edit the Type of Services mappings.

2. Click Edit () icon and modify the Type of Services metrics as follows:

   ToS ID

   This field is not editable. This field implements the Type of Service on the NetFlow packet to tradeoff on delay, throughput, reliability, and cost.

   ToS Name

   You can specify any name to your Type of Service class. Typically, the classes and their IDs are as follows:

   DSCP Code	DSCP ID (Decimal format)	IP Precedence
   Best Effort	0	0 - Routine or Best Effort
   CS1, AF11-13	8,10,12,14	1 - Priority
   CS2, AF21-23	16,18,20,22	2 - Immediate
   CS3, AF31-33	24,26,28,30	3 - Flash - used for voice signaling
   CS4, AF41-43	32,34,36,38	4 - Flash Override
   CS5, EF	40, 46	5 - Critical - used for voice RTP
   CS6	48	6 - Internetwork Control
   CS7	56	7 - Network Control

   Where:

   • CS - Class Selector
   • AFxy - Assured Forwarding (x=class, y=drop precedence)
   • EF - Expedited Forwarding

   Note: Traffic classification is an automated process that categorizes network traffic according to various parameters into a number of traffic classes.

   Note: The ToS names must be unique.
