Hardware

DS3 SFP Support for ES+ Line Cards (CISCO-SFP-T3-GE=)

DS-3 connections can be terminated today on the Cisco 7600 Series on various channelized and clear-channel SPAs and on SIP-400 line cards. The new DS-3 SFP supports ES+ Gigabit Ethernet interfaces, forwarding Ethernet packets to a TDM-based WAN at full duplex DS-3 wire speed. Support of DS-3 Ethernet connections brings multiple benefits to the customer: no need for a dedicated slot for TDM circuits, an Ethernet layer with EVC features and other ES+ features such as video monitoring (VidMon), and an efficient way to prepare for migration toward Gigabit Ethernet services.

Here is the PID and the Supported ES+ Modules

The feature requires the support of Ethernet over DS-3 and HDLC framing on the equipment terminating the circuits, and is supported on Cisco 7600 Series Routers as well as on the Cisco MWR 2941_DC Mobile Wireless Router.

SDH Support for SPA-1XCHSTM4/OC12 (SPA-1xCHOC12/DS0=)

This feature introduces SDH mapping support for the CHOC12 SPA in Cisco 7600 Series Routers. SDH customers can use this high-density SPA to aggregate TDM circuits from their mobile backhaul applications or straight TDM connections.

This SPA is supported on Cisco 7600 SIP-400 line cards with all route switch processors (RSPs) and supervisors and all chassis types.

E3 and Channelization Support for SPA-2CHT3-CE-ATM (SPA-2CHT3-CE-ATM=)

This feature introduces E3 support for the E3/T3 CEoP SPA as well as channelization. Circuit emulation has been widely deployed by service providers and enterprise customers who use Cisco 7600 Series Routers and wish to continue using their existing TDM networks while migrating to IP networks. Adding E3 support expands its applicability to the SDH market, and adding channelization support expands its applicability to aggregating T1/E1 interface cards.

This SPA is supported on Cisco 7600 SIP-400 line cards for all RSPs and supervisors and all chassis types.

Carrier Ethernet Features

EVC Port Channel Per Flow Load Balancing

EVC PortChannel support is enhanced by the introduction of per-flow load balancing. This feature completes the set of load-balancing mechanisms offered for EVC PortChannels; the other available mechanisms are per-EVC, manual, and weighted load balancing. Per-flow load balancing splits the traffic from a single EVC over multiple member links to achieve throughputs of over 1 Gbps on a single EVC. Per-flow load balancing can improve network scale, simplify operations, and improve resilience without sacrificing SLAs.

This feature is supported on ES+ line cards.

Portchannel EVC enhancements for ES20 and ES+

The Cisco EVC infrastructure supports the scaling of services, creates new service opportunities, and lowers operational costs with features that include local VLAN significance and flexible VLAN tag manipulation. Cisco continues to deliver more enhancements to EVC support when link aggregation is required.

New EVC enhancements for PortChannels include:

Custom EtherType on ES20 line cards

MST and MST-AG for ES+ and ES20 line cards

Unidirectional Link Detection (UDLD) for ES+ and ES20 line cards

Layer 2 access control lists (ACLs) for ES+ line cards

Layer 3 and Layer 4 ACLs for ES+ line cards

DHCP Snooping and Dynamic Address Resolution Protocol (ARP) inspection for ES+ and ES20 line cards.

EVC support is available on ES+, ES20, and SIP-400 line cards.

LST (Link State Tracking) for REP and MST

LST improves network resilience with new automatic recovery mechanisms that are triggered if uplinks fail. REP provides rapid recovery mechanisms for Ethernet-based access rings. As an alternative, MST is commonly used for Ethernet access resilience in hub-spoke or star topologies. With LST, the REP ring or spanning tree will reconverge to its alternative path upon notification that upstream communication to the ring is lost. Downtime is reduced and overall network resilience is improved because the Cisco Carrier Ethernet network responds automatically.

Resilient Ethernet Protocol no-edge-neighbor

REP provides fast reconvergence and traffic recovery when a link in a ring fails. Fast reconvergence is achieved by notifying all nodes in the ring with a hardware-switched control message that activates the redundant path to the core network.


In access-ring topologies where the aggregation nodes do not support REP, but convergence times like those of REP are desired, one solution is to construct a REP segment with no edge ports. The REP no-edge-neighbor feature adds the capability for fast recovery without participation of the edge device in the REP protocol. The feature also provides interoperability between the Cisco 7600 Series REP and Cisco ASR 9000 Series Aggregation Services Routers REP-AG.

Per Subscriber Session Call Admission Control

CAC limits the number of active sessions that can be established based on CPU and critical system resources. Rate limitation of session initiation messages is provided for Point-to-Point Protocol (PPP) and IP sessions to preserve system capability in the event of excess session requests. This security protection improves operations performance for broadband by helping to ensure that during peak session demand the system remains stable and is protected against CPU utilization spikes.

Per-subscriber-session CAC is available only for ES+3CXL line cards (ES+, ES+XT, and ES+XC 3CXL models); it is not available for ES+T line cards.

A Cisco 7600 Intelligent Services Gateway (ISG) license is required for PPP or IP sessions.

VPLS Inter-AS Option B

VPLS Inter-AS VPLS, like Layer 3 VPN, can be deployed using option A, B, or C. Options A and C can be deployed with previous releases. Option B provides an additional level of security as compared to option C, while simplifying operations as compared to Option A. Option B requires BGP autodiscovery for VPLS. It is NSF and SSO compliant.

This feature is supported for ES+, ES20 and SIP-400 (all line cards required to support VPLS).

Mobile Transport Features

Hot Standby PW Support for ATM and TDM Access Circuits

Pseudowire Preferential Forwarding was developed for PortChannel Ethernet access circuits in Cisco Services-Ready Engine (SRE) Modules. Preferential Forwarding allows a backup pseudowire to be preprovisioned, which facilitates a fast switchover from the active state to the standby state. This feature extends that capability to ATM, TDM, and physical Ethernet access circuits, providing fast recovery with resilient pseudowire for all three access circuit types and improving SLA performance.

This feature is supported on Cisco 7600 Series Routers through Cisco 7600 SIP-400 and ES+ line cards.

ACR support for CEM

This feature introduces ACR support for TDM and Ethernet in addition to ATM. This feature also adds local switching support for TDM and ATM circuits while offering ATM shaping functions for ATM Virtual Paths. Customers can achieve fast end-to-end convergence while interconnecting access circuits to the MPLS network through circuit emulation. Local switching and ATM shaping also allow customers to use the same platform to connect existing circuits, for an easier transition to IP NGN.

This feature is supported on Cisco 7600 SIP-400 line cards and the SPA-1CHOC3-CE-ATM.

BFD Over SVI on 7600

BFD is supported for SVI with the same scalability and feature support as for other types of Layer 3 interfaces. When deployed on Layer 2 networks, BFD timers must be configured according to the expected Layer 2 convergence to avoid BFD and Layer 2 convergence race conditions.

1588v2 Feature Enhancements on Metronome SPA

This release provides more flexibility by adding ISO 8601 TOD format support to the IEEE 1588v2 solution on the Cisco 7600 Series Router.

This feature is supported for the Metronome SPA.

SSM support on SPA-1XCHOC12/DS0 and SPA-1XOC48POS/RPR

This feature adds SSM support for additional SPAs, including SPA-1XCHOC12/DS0 and SPA-

1XOC48POS/RPR, improving synchronization is on the SPAs for TDM operation and providing interoperability with Synchronous Ethernet.

This feature is supported with SSM support for SPA-1XCHOC12/DS0 and SPA-1XOC48POS/RPR.

Video Features

Configurable MPEG Video PIDs for Inline Video Monitoring

The previous video monitoring implementation (MDI metric) learns the first five PIDs seen in an MPEG video. The learned PIDs can identify any type of data, including video, audio, and control data. Configurable MPEG video PIDs allow users to specify that only video PIDs are learned; these are considered the most critical PIDs.

This feature is supported for ES+ line cards.

Inline video monitoring is available with the purchase of the 76-ES+VIDEO-LIC license.

MPLS Encapsulation Support for Inline Video Monitoring

This feature allows inline video monitoring for MPLS-encapsulated packets on MPLS-enabled interfaces. The feature supports the following MPLS scenarios:

MPLS swap: tag to tag; router responsible for switching MPLS packets

MPLS pop: tag to IP; router responsible for label disposition of last MPLS tag

MPLS push: IP to tag; router responsible for label imposition of first MPLS tag

Ethernet-over MPLS (EoMPLS) and VPLS

MPLS Layer 3 VPN

Unicast LDP and MLDP

Point-to-Multipoint Traffic Engineering (P2MP-TE) and unicast TE

The inline video monitoring implementation is independent of the number of MPLS labels present in a packet.

This feature is supported for ES+ line cards.

Inline video monitoring is available with the purchase of the 76-ES+VIDEO-LIC license.

IP Delay Variation Support for Inline Video Monitoring

IPDV allows measurement of the per-packet IP delay variation. This feature can measure IPDV for VBR or CBR flows. IPDV is video-rate independent and does not require users to configure a reference VBR or CBR rate.

To see a video demonstration of Cisco inline video monitoring, visit http://www.cisco.com/web/solutions/routingswitching/vidmon.html


This feature is supported for ES+ line cards.

Inline video monitoring is available with the purchase of the 76-ES+VIDEO-LIC license.

mLDP: mVPN Extranet

This feature allows extranet capabilities in MVPN. The extranet allows VPN closed user groups to share information, with common multicast information distributed across multiple VPN customers.

Label Switched Multicast (LSM) MLDP-Based MVPN Support

LSM is a solution framework providing multicast services over an MPLS and Generalized MPLS (GMPLS) backbone network. This feature uses extensions to MPLS label switching to achieve MVPN across the IP and MPLS core cloud, without requiring them to be multicast aware (which was required for GRE-based MVPN).

This release supports MLDP MVPN extranet receiver-side chaining.

Quality of Service Features

Service Groups for Subinterfaces and Access Subinterfaces

Service groups can apply a common QoS policy to a group of logical interfaces residing on the same physical port or PortChannel. Service groups are a flexible way to create a shared treatment of aggregate traffic. This release extends the service group concept to support subinterfaces for IP services, access subinterfaces for residential services, and EVCs. Service groups for subinterfaces are not supported over PortChannels. With these enhancements to service groups, service providers can improve QoS implementations for business, residential, and wholesale services across N:1 or 1:1 service models, saving bandwidth and simplifying provisioning.

Service groups for subinterfaces are available for ES+ and ES20 line cards. Access subinterfaces are available only for ES+ line cards.

Port Level Shaping support concurrent with 4HQoS on ES+

In many situations, a subscriber-facing Gigabit Ethernet port will need to operate at less than line rate; for example, when connecting to Ethernet over SONET, SDH, microwave, or subrate E-Line service. Support for port-level shaping allows configuration of a modular QoS command-line interface (MQC) policy map on the physical port for shaping, and also configuration of QoS on logical interfaces such as subinterfaces, EVCs, or service groups. This provides the capability for managing residential traffic and business SLAs with three- or four-level HQoS service definitions, regardless of downstream speed limitations.

This feature is available for all ES+ line cards.

Minimum Bandwidth Guarantee Support for Service Groups

Previous releases supported configuration of HQoS per service group using only bandwidth remaining ratio at the parent policy level. This defined weight for each service group was used to determine how much bandwidth to assign to a service group during times of congestion, but only in a relative manner. With minimum bandwidth support, each service group can be assigned an absolute bandwidth value, expressed as a percentage or as kbits per second.

This is especially useful if three-level scheduling (HQoS per EVC or subinterface only and four-level scheduling (HQoS per subinterface EVC and flat QoS on a service group) are combined on the same port. Assigning minimum bandwidth values to all service groups (four-level schedulers) implicitly defines the aggregate minimum bandwidth for all three-level schedulers, allowing optimal flexibility and QoS fine-tuning.

This feature is supported for all ES+ line cards.
