software in the switch (which manages policies downloaded from an LDAP server) through the qos

forward log command.

Clearing the QoS Log

The QoS log can get large if invalid rules are configured on the switch, or if a lot of QoS events have

taken place. Clearing the log makes the file easier to manage.

To clear the QoS log, use the qos clear log command. For example:

-> qos clear log

All the current lines in the QoS log are deleted.

Classifying Bridged Traffic as Layer 3

In some network configurations you may want to force the switch to classify bridged traffic as routed

(Layer 3) traffic. Typically this option is used for QoS filtering. See Chapter 27, “Configuring ACLs,” for

more information about filtering.

The Layer 3 classification of bridged traffic is no different from the classification of normal Layer 3

routed traffic. Note that this implementation of QoS always performs Layer 3 classification of bridged

traffic; it is not an option. As a result,

• Layer 3 ACLs are always effected on bridged traffic.

• The switch may bridge and route traffic to the same destination.

• Bridged IP packets are prioritized based on ToS, not 802.1p.

Note that Layer 3 ACLs are effected on bridged IP traffic and Layer 2 ACLs are effected on routed traffic.

Setting the Statistics Interval

To change how often the switch polls the network interfaces for QoS statistics, use the qos stats interval

command with the desired interval time in seconds. The default is 60 seconds. For example:

-> qos stats interval 30

Statistics are displayed through the show qos statistics command. For more information about this

command, see the OmniSwitch CLI Reference Guide.

Returning the Global Configuration to Defaults

To return the global QoS configuration to its default settings, use the qos reset command. The defaults

will then be active on the switch. For a list of global defaults, see “QoS Defaults” on page 26-9.

Note. The qos reset command only affects the global configuration. It does not affect any policy configu-

ration.
