OmniSwitch QoS policies

General Information

OmniSwitch QoS provides a way to control traffic flows through the switch based on configured policies. The control may be simple such as allowing or denying traffic, or complicated such as remapping 802.1p bits from a Layer 2 network to ToS values in a Layer 3 network.

The OmniSwitch supports the following types of QoS policies:

• basic QoS—to control traffic prioritization and bandwidth shaping

• ACLs—for Layer 2, 3, and 4 filtering

A QoS policy contains a condition and an action. The condition specifies parameters that the switch checks in incoming traffic flows, such as the destination address or ToS bits. The action specifies what the switch does with traffic that matches the condition; for example, the switch may queue the traffic flow with a higher priority or reset the ToS bits.

Ethernet service policies are used to create UNI and SAP profiles. The profiles are applied to stacked VLAN SAPs and UNIs to control traffic and specify options to manage certain traffic types.
