Figure 3-93 IP Port Priority

CLI* – The following example globally enables IP Port Priority service on the switch, maps HTTP traffic on port 5 to CoS value 0, and then displays all the IP Port Priority settings for that port.

Console(config)#map		ip port	4-204
Console(config)#interface ethernet 1/5
Console(config-if)#map ip port 80 cos 0			4-205
Console(config-if)#end
Console#show map ip		port ethernet 1/5	4-205
TCP port mapping status: disabled
Port	Port no. COS
--------- --------		---
Eth 1/ 5	80	0
Console#

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

Quality of Service

The commands described in this section are used to configure Quality of Service (QoS) classification criteria and service policies. Differentiated Services (DiffServ) provides policy-based management mechanisms used for prioritizing network resources to meet the requirements of specific traffic types on a per hop basis. Each packet is classified upon entry into the network based on access lists, IP Precedence, DSCP values, or VLAN lists. Using access lists allows you select traffic based on Layer 2, Layer 3, or Layer 4 information contained in each packet. Based on configured network policies, different kinds of traffic can be marked for different kinds of forwarding.
