Configuring QoS Interaction With Other Features
OmniSwitch AOS Release 6 Network Configuration Guide September 2009 page 40-5
Valid Policies
The switch does not allow you to create invalid condition/action combinations; if you enter an invalid
combination, an error message will display.
A list of valid condition and condition/action combinations is given in “Condition Combinations” on
page 40-6 and “Action Combinations” on page 40-8.
It is possible to configure a valid QoS rule that is active on the switch, however the switch is not able to
enforce the rule because some other switch function (for example, routing) is disabled. See the condition
and condition/action combinations tables for more information about valid combinations (“Condition
Combinations” on page 40-6 and “Action Combinations” on page 40-8).
Interaction With Other Features
QoS policies may be an integral part of configuring other switch features, such as Link Aggregation. In
addition, QoS settings may affect other features in the switch; or QoS settings may require that other
switch features be configured in a particular way.
A summary of related features is given here:
• Dynamic Link Aggregates—Policies may be used to prioritize dynamic link aggregation groups. For
details, see Chapter 23, “Configuring Dynamic Link Aggregation.”
• 802.1Q—Tagged ports are always trusted, regardless of QoS settings. For information about configur-
ing ports with 802.1Q, see Chapter 21, “Configuring 802.1Q.”
• Mobile Ports—Mobile ports are always trusted, regardless of QoS settings. For information about
setting up mobile ports, see Chapter 6, “Assigning Ports to VLANs.”
• LDAP Policy Management—Policies may also be configured through the PolicyView application and
stored on an attached LDAP server. LDAP policies may only be modified through PolicyView. For
information about setting up a policy server and managing LDAP policies, see Chapter 38, “Managing
Policy Servers.”
• VLAN Stacking Service—VLAN Stacking ports are always trusted and default classification is set to
802.1p. QoS policy conditions to match the inner VLAN tag and inner 802.1p tag are available for
classifying customer information contained in VLAN Stacking frames. For information about VLAN
Stacking see Chapter 9, “Configuring VLAN Stacking.”
• Quarantine Manager and Remediation (QMR)—Configuring QMR and QoS inner VLAN or inner
802.1p policies is mutually exclusive. QMR overlays the inner VLAN tag, thus creating a conflict with
related QoS policies. This is also true with QMR and VLAN Stacking services. For more information
about QMR, see “Using Quarantine Manager and Remediation” on page 40-16.
• User Network Profiles—The Access Guardian User Network Profile (UNP) feature provides the abil-
ity to assign a list of QoS policy rules to a profile. The rules contained in the list are applied to any
device that is assigned to the UNP. For information about configuring policy lists for profiles, see
Chapter 34, “Configuring Access Guardian.”
