Quality of Service

If your Catalyst 6500 series switch or Cisco 7600 series router is running Cisco IOS software on the MSFC2 and Catalyst software on the supervisor engine, QoS is configured using the Modular QoS Command Line Interface (MQC) and the Catalyst 6500 supervisor engine CLI commands. If you are running Cisco IOS software only, QoS is configured using existing Modular QoS Command Line Interface (MQC).

Refer to the Cisco IOS QoS solutions publications and Catalyst 6500 publications listed below for QoS configuration information.

The OSMs support the following QoS implementations:

Differentiated services code point (DSCP) and IP precedence classification

Class-based traffic shaping

Class-based weighted fair queuing (CBWFQ)

For a list of the modules that support CBWFQ, see Chapter 9 "Configuring QoS on the Optical Services Modules."

Low latency queuing (LLQ)

Weighted Random Early Detection (WRED)

For a list of the modules that support WRED, see Chapter 9 "Configuring QoS on the Optical Services Modules."

Hierarchical Shaping (supported on Frame Relay, ARPA, dot1q, HLDC, and PPP encapsulations.)

For QoS configuration information and examples, see Chapter 9 "Configuring QoS on the Optical Services Modules."

For general information on how to configure QoS, refer to the Cisco IOS Quality of Service Solutions Configuration Guide and the Cisco IOS Quality of Service Solutions Command Reference publication at these URLs:

Destination Sensitive Services

Destination Sensitive Services (DSS) allow traffic accounting and traffic shaping to known autonomous system numbers in order to better engineer and plan network circuit peering and transit agreements. DSS is supported on ingress and egress POS ports on the OC-3, OC-12, and OC-48 POS OSMs and on the GE-WAN ports on the four-port Gigabit Ethernet WAN (GBIC) OSMs.

DSS consists of these two components:

Destination Sensitive Billing (DSB)

DSB allows accounting based on destination traffic indexes and provides a means of classifying customer traffic according to the route that the traffic travels. Trans-Pacific, Trans-Atlantic, satellite, domestic, and other provider traffic can be identified and accounted for on a destination network basis when the customer traffic is on a unique software interface. DSB provides packet and byte counters, which represent counts for IP packets per destination network. DSB is implemented using route-maps to classify the traffic into one of seven possible indexes, which represent a traffic classification.

Destination Sensitive Traffic Shaping (DSTS)

DSTS performs inbound and outbound traffic shaping based on the destination traffic index configuration. DSTS is supported with ingress DSS only.

See Chapter 10 "Configuring Destination Sensitive Services on the Optical Services Modules" for configuration information.

Multiprotocol Label Switching

MPLS is supported on all Catalyst 6500 and Cisco 7600 series modules.

For information about platform-specific limitations and restrictions, and supported features, see Chapter 11 "Configuring Multiprotocol Label Switching on the Optical Services Modules."

For information on MPLS and how to configure it on the OSMs, refer to the Multiprotocol Label Switching on Cisco Routers Feature Module at this URL:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121newft/121t/121t5/mpls4t.htm.

For general information on MPLS, refer to Multiprotocol Label Switching at this URL:

http://www.cisco.com/en/US/products/ps6557/products_ios_technology_home.html

Ethernet over Multiprotocol Label Switching

Ethernet over Multiprotocol Label Switching (EoMPLS) is supported on all all Catalyst 6500 and Cisco 7600 series modules and the FlexWAN modules. You can configure EoMPLS using PFC3BXL-based systems or OSM-based systems.

EoMPLS allows you to connect two VLAN networks that are in different locations without using bridges, routers, or switches at the VLAN locations. You can enable the MPLS backbone network to accept Layer 2 VLAN traffic by configuring the label edge routers (LERs) at both ends of the MPLS backbone.

For information about EoMPLS and how to configure it, see Chapter 11 "Configuring Multiprotocol Label Switching on the Optical Services Modules."
