Configuring QoS
QoS configuration involves the following general steps:
1
Configuring Global Parameters. In addition to enabling/disabling QoS, global configuration includes
settings such as global port parameters and various timeouts. The type of parameters you might want to
configure globally depends on the types of policies you can configure. For example, if you want to set up
policies for 802.1p or ToS/DSCP traffic, you can configure all ports as trusted ports.
Typically, you need not change any of the global defaults. See
list of the global defaults. See
configuring global parameters.
2
Configuring QoS Port Parameters. This configuration includes setting up QoS parameters on a per
port basis. Typically you do not need to change the port defaults. See
for a list of port defaults. See
page 21-20
for information about configuring port parameters.
3
Configuring Queue Set (QSet) Profiles. The queue management configuration for the ingress virtual
output queues (VOQ) is applied using embedded QSet profiles. A default profile configuration is applied
when the switch comes up. Selecting different profiles is only necessary if the default profile settings are
not sufficient. See
"Queue Management Defaults" on page 21-31
"Congestion Management" on page 21-10
4
Setting Up Policies. Most QoS configuration involves setting up policies. See
page
21-39.
5
Applying the Configuration. All policy rule configuration and some global parameters must be
specifically applied through the qos apply command before they are active on the switch. See
