Service-Policy (Interface Configuration) - Cisco Catalyst 4500 Series Command Reference Manual

Chapter 2 Cisco IOS Commands for the Catalyst 4500 Series Switches

service-policy (interface configuration)

To attach a policy map to an interface or to apply different QoS policies on VLANs that an interface
belongs to, use the service-policy command. To remove a policy map from an interface, use the no form
of this command.

Command Modes

Command History Release

12.2(25)EWA
Usage Guidelines
Layer 2 interfaces can be part of multiple VLANs (for example, a typical trunk port). In conjunction with
the vlan-range command, you can use the service-policy command to specify different QoS policies on
different VLANs.
Note This capability is restricted to Layer 2 interfaces.
You can apply a service policy under an interface as well as a VLAN range at the same time. However,
this is allowed only when the interface policy has only queuing actions whereas a VLAN has only
non-queueing actions (QoS marking and/or policing) actions.
To attach a service policy to a VLAN, the VLAN configuration mode has to be used.
Examples
This example shows how to attach a policy map to Fast Ethernet interface 5/20:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface fastethernet 5/20
Switch(config-if)# service-policy input pmap1
Switch(config-if)# end
