Configuring the Switch
Click Priority, IP Port Priority. Enter the port number for a network application in the
IP Port Number box and the new CoS value in the Class of Service box, and then
click Apply.
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
Console(config)#interface ethernet 1/5
Console(config-if)#map ip port 80 cos 0
Console(config-if)#end
Console#show map ip port ethernet 1/5
TCP port mapping status: disabled
Port Port no. COS
--------- -------- ---
Eth 1/ 5

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.
