---

–The following restrictions apply to FFR.16 with the Channelized OSMs:

–There is a maximum 168 bundles with two T1/E1 links.

Quality of Service

If you are running Cisco IOS software, QoS is configured using existing Modular QoS Command Line Interface (MQC).

Refer to the Cisco IOS QoS solutions 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 10 "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 10 "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 10 "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:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fsecur_c/index.htm

http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/qos_r/index.htm

Multiprotocol Label Switching

MPLS is supported on all Cisco 7600 series modules.

For information about platform-specific limitations and restrictions, and supported features, see Chapter 9 "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/univercd/cc/td/doc/product/software/ios122/122cgcr/fswtch_c/swprt3/index.htm

Ethernet over Multiprotocol Label Switching

Ethernet over Multiprotocol Label Switching (EoMPLS) is supported on all Cisco 7600 series modules andon the Enhanced FlexWAN module. 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 9 "Configuring Multiprotocol Label Switching on the Optical Services Modules."
