Attaching a Policy Map to an Interface
To attach a policy map to an interface, perform this task:
When attaching a policy map to an interface, note the following information:
•Do not attach a service policy to a port that is a member of an EtherChannel.
•With DFCs installed, PFC2 does not support VLAN-based QoS: you cannot enter the mls qos
vlan-based command or attach service policies to VLAN interfaces.
•PFC QoS supports the output keyword only with a PFC3 and only on Layer 3 interfaces (either LAN
ports configured as Layer 3 interfaces or VLAN interfaces). With a PFC3, you can attach both an
input and an output policy map to a Layer 3 interface.
•VLAN-based or port-based PFC QoS on Layer 2 ports is not relevant to policies attached to Layer
3 interfaces with the output keyword.
•Policies attached with the output keyword do not support microflow policing.
•You cannot attach a policy map that configures a trust state with the service-policy output
command.
•Filtering based on IP precedence or DSCP in policies attached with the output keyword uses the
received IP precedence or DSCP values. Filtering based on IP precedence or DSCP in policies
attached with the output keyword is not based on any IP precedence or DSCP changes made by
ingress QoS.
Command Purpose
Step1 Router(config)# interface {{vlan vlan_ID} |
{type1slot/port[.subinterface]} | {port-channel
number[.subinterface]}}
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
Selects the interface to configure.
Step2 Router(config-if)# service-policy [input |
output] policy_map_name
Attaches a policy map to the interface.
Router(config-if)# no service-policy [input |
output] policy_map_name
Removes the policy map from the interface.
Step3 Router(config-if)# end Exits configuration mode.
Step4 Router# show policy-map interface {{vlan vlan_ID}
| {type1slot/port} | {port-channel number}}
Verifies the configuration.
