Enabling Qos Globally - Cisco Catalyst 3560-X Software Configuration Manual

Configuring Standard QoS

Enabling QoS Globally

By default, QoS is disabled on the switch. To enable IPv6 QoS on the switch, you must first configure a
dual-ipv4-and ipv6 SDM template and reload the switch. This template enables both IPv4 and IPv6 QoS
configuration.
Beginning in privileged EXEC mode, follow these steps to enable QoS. This procedure is required.
Command
Step 1 configure terminal
Step 2 mls qos
Step 3 end
Step 4 show mls qos
Step 5
copy running-config
startup-config
To disable QoS, use the no mls qos global configuration command.
Enabling VLAN-Based QoS on Physical Ports
By default, VLAN-based QoS is disabled on all physical switch ports. The switch applies QoS, including
class maps and policy maps, only on a physical-port basis. In Cisco IOS Release 12.2(25)SE or later,
yYou can enable VLAN-based QoS on a switch port.
Beginning in privileged EXEC mode, follow these steps to enable VLAN-based QoS. This procedure is
required on physical ports that are specified in the interface level of a hierarchical policy map on an SVI.
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 mls qos vlan-based
Step 4
end
Step 5
show mls qos interface interface-id
Step 6 copy running-config startup-config
Use the no mls qos vlan-based interface configuration command to disable VLAN-based QoS on the
physical port.
