Configuring DSCP Values for an Interface

QoS assigns the DSCP value specified with this command to non IPv4 frames received on interfaces
configured to trust DSCP and to all frames received on interfaces configured as untrusted.
To configure the DSCP value for an ingress interface, perform this task:
Command
Step 1
Switch(config)# interface {fastethernet |
gigabitethernet | tengigabitethernet}
slot/interface
Step 2
Switch(config-if)# [no] qos dscp default_dscp
Step 3
Switch(config-if)# end
Step 4
Switch# show qos interface {fastethernet |
gigabitethernet | tengigabitethernet}
slot/interface
This example shows how to configure the DSCP 5 as the default on Fast Ethernet interface 5/24:
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# interface fastethernet 5/24
Switch(config-if)# qos dscp 5
Switch(config-if)# end
Switch#
This example shows how to verify the configuration:
Switch# show qos interface fastethernet 6/1
