CONFIGURING THE SWITCH

Mapping IP Precedence

The Type of Service (ToS) octet in the IPv4 header includes three precedence bits defining eight priority levels ranging from highest priority for network control packets to lowest priority for routine traffic. Bits 6 and 7 are used for network control, and the other bits for various application types. The ToS bits are defined in the following table.

Priority Level	Traffic Type
7	Network Control

6	Internetwork Control

5	Critical

4	Flash Override

3	Flash

2	Immediate

1	Priority

0	Routine

Fields and Attributes

•IP Precedence/DSCP Priority Status – Selects IP Precedence, DSCP, or disables both priority services.

•IP Precedence Priority Table – Shows the IP Precedence to CoS map.

•Class of Service Value – Maps a CoS value to the selected IP Precedence value. Note that “0” represents low priority and “7” represents high priority.
