3 Configuring the Switch

CLI – The following example globally enables IP Precedence service on the switch, maps IP Precedence value 1 to CoS value 0 (on port 1), and then displays the IP Precedence settings.

Console(config)#map		ip precedence			4-204
Console(config)#interface				ethernet 1/1	4-131
Console(config-if)#map ip				precedence 1 cos 0	4-206
Console(config-if)#end
Console#show map ip		precedence ethernet 1/1			4-209
Precedence	mapping status: enabled
Port	Precedence COS
---------	---------- ---
Eth 1/ 1		0	0
Eth 1/ 1		1	0
Eth 1/ 1		2	2
Eth 1/ 1		3	3
Eth 1/ 1		4	4
Eth 1/ 1		5	5
Eth 1/ 1		6	6
Eth 1/ 1		7	7
Console#

Note: Mapping specific values for IP Precedence is implemented as an interface configuration command, but any changes will apply to the all interfaces on the switch.

Mapping DSCP Priority

The DSCP is six bits wide, allowing coding for up to 64 different forwarding behaviors. The DSCP replaces the ToS bits, but it retains backward compatibility with the three precedence bits so that non-DSCP compliant, ToS-enabled devices, will not conflict with the DSCP mapping. Based on network policies, different kinds of traffic can be marked for different kinds of forwarding. The DSCP default values are defined in the following table. Note that all the DSCP values that are not specified are mapped to CoS value 0.
