Enabling Per-Port Per-VLAN QoS
The per-port per-VLAN QoS feature enables you to specify different QoS configurations on different
VLANs on a given interface. Typically, you will use this feature on trunk or voice VLANs (Cisco IP
Phone) ports, as they belong to multiple VLANs.
To configure per-port per-VLAN QoS, perform this task:
Command Purpose
Step 1
Switch(config)# interface {fastethernet | gigabitethernet |
tengigabitethernet}
slot/interface
| Port-channel
number
Selects the interface to configure.
Step 2
Switch(config-if)# vlan-range
vlan_range
Specifies the VLANs involved.
Step 3
Switch(config-if-vlan-range)# service-policy
{input | output}
policy-map
Specifies the policy-map and direction.
Step 4
Switch(config-if-vlan-range)# exit
Exits class-map configuration mode.
