Ethernet OAM
ITU-T Y.1731 Performance Monitoring for the Cisco 7600 Series
Y.1731 performance monitoring provides standardized real-time measurements for frame loss, frame delay, and frame delay across Ethernet networks. Service providers can measure critical performance metrics on their networks directly from the Cisco 7600 Series Router, without deploying expensive probes.
When used in conjunction with CFM (IEEE 802.1ag), Y.1731 provides a comprehensive fault management and performance monitoring solution for service providers to save OpEx, improve SLAs, and simplify operations.
Cisco's Y.1731 performance monitoring complies with international standards per ITU-T Y.1731 2/2008 Section 8.0 (Performance Monitoring) requirements as defined and interpreted by the Metro Ethernet Forum (MEF), primarily through their SOAM PM IA (MEF-17) Draft Specification.
To support one-way delay measurements, IEEE 1588 Precision Time Protocol (PTP) is needed. To provide PTP, the Cisco Timing SPA (SPA-2X1GE-SYNCE) is required on the system, operating in server mode.
Y.1731 PM is available only on the Cisco ES+ Series line cards.
Carrier Ethernet and QoS
Dynamic Ethernet Service Activation
Dynamic Ethernet service activation provides:
• Zero-touch configuration and service activation for Ethernet through RADIUS
• Dynamic changes to Ethernet services (push) through RADIUS
• Automatic Ethernet over Multiprotocol Label Switching (EoMPLS) service configuration
• RADIUS accounting for Ethernet services
With dynamic Ethernet service activation, service policies are automatically applied to Ethernet Flow Points (EFPs) based on the classification of the traffic when it initially arrives on an EFP to turn-up the service. Each aspect of the EVC can be configured in the service policy and activated through RADIUS. Services can also be also mapped automatically to different Layer 2 transport types, such as bridge domains or x-connect. MPLS Pseudowire Emulations (PWEs) can be automatically initiated as well. Dynamic Ethernet service activation also provides RADIUS accounting for Ethernet flows for scalable accounting applications.
Dynamic Ethernet service activation creates synergy between the Cisco EVC and ISG infrastructures to automate provisioning and network management, creating new service opportunities for cloud, wholesale, business, and mobile markets.
This feature is available only on Cisco ES+ 3CXL line cards used with Cisco RSP 720 Route Switch Processors.
SPAN on EVC Service Instance
SPAN is a traffic monitoring technology that allows customers to configure the Layer 2 switchport to mirror data passing through any other switchport. Starting with Cisco IOS 15.1(2)S, SPAN functions are available on a per-service-instance basis, which provides more specificity for monitoring on EVCs, and simplifies the transition from switchport to EVC deployments.
This feature is available only on Cisco ES+ series line cards
Port Channel EVC MST and MST-AG; BPDU Pseudowire on LAG NNI
MST-AG is already supported on the Cisco 7600 Series and provides fast recovery for access networks connecting to Virtual Private LAN Services (VPLS), using standard MST in the access network.
Starting with Cisco IOS Release 15.1(2)S, port channel can be used to carry the special control pseudowire that connects the two network Provider Edge (N-PE) systems that act as access gateways, further improving the excellent resiliency of MST-AG solutions.
This feature is available only with Cisco ES20 and ES+ series line cards
REP MIB
REP can provide consistent sub-50 recovery for Ethernet in a ring topology. The Cisco REP MIB provides SNMP access to segment information per node, including port information and interface statistics relevant to REP.
This feature is available with REP on LAN cards, ES20, and ES+ series line cards
SSO Support for REP Fast Hello
SSO support for REP Fast Hello enhances high availability of the Cisco 7600 Series in Layer 2 applications.
This feature is available only with S-Series chassis (7603-S,7606-S, or 7609-S) or Cisco 7604 chassis using SUP-720, RS-720-1G or RSP-720-10G rout processors.
IP Source Guard on Port Channel EVC
IP Source Guard provides IP and MAC filtering to restrict IP traffic on an untrusted port. Only IP traffic with source IP and MAC address corresponding to valid IP source binding is permitted and all other IP traffic except DHCP is dropped. Beginning with Cisco IOS 12.2(33)SRD, IP Source Guard is available on a per-service-instance basis. With Cisco IOS 15.1(2)S, IP Source Guard on EVC service instances is also supported with port channel. Network transitions from switchport configurations to EVC are now simplified, making it easier to take advantage of new services and operational benefits that come with EVCs.
This feature is available only with ES+ series line cards.
Cisco ISG Security CoPP Enhancements
Beginning with Cisco IOS 12.2(33)SRE, ES+ line cards support control plane policing on Cisco ISG access subinterfaces and on main interfaces. This release adds Cisco ISG CoPP for subinterfaces without the access keyword to improve security for more configuration options. CoPP on nonaccess subinterfaces applies only to Address Resolution Protocol (ARP), DHCP, PPPoE, and EOAM protocols.
This feature is available with Cisco ISG only on ES+ 3CXL line cards and RSP-720.
Layer 2, 3, and 4 ACL Classification for EVC on ES+
Two types of ACLs can be used inside Modular QoS command-line interface (MQC) class maps for defining traffic classification of ingress and egress QoS.
• MAC ACLs are typically used in Carrier Ethernet networks providing Layer 2 services. By using named MAC ACLs, traffic can be classified on either destination or source MAC address; classification on both source and destination is not supported. Inside the MAC ACLs, VLAN IDs and CoS values may also be included for more detailed classification.
mac access-list extended my-L2-acl
permit 0000.0000.9e15 ffff.ffff.0000 any
class-map match-all L2-acl
match access-group name my-L2-acl
• IP ACLs are typically used in IP/MPLS networks providing Layer 3 services. By using either named or numbered standard or extended IP ACLs, traffic can be flexibly classified based on either Layer 3 source or destination IP address information or on Layer 3 protocol port numbers. In addition, the differentiated services code point (DSCP) information can be used.
ip access-list extended my-L3-acl
permit ip 10.1.1.0 0.0.0.225 any dscp ef
class-map match-all L3-acl
match access-group name my-L3-acl
This feature is available on ES+ line cards only; it is not supported on ES20 or SIP-400 line cards.
Egress QoS Scheduling (Shape and Queue) for Subinterfaces on Port Channel on ES+
The following high-performance port channel features are of value for QoS-supporting Provider Edge Routers:
• Port channel bundling of two or more links into one logical link for either redundancy or link capacity purposes
• Customer traffic spread across all port channel member links based on per-flow load balancing
• Per-customer service hierarchical QoS (HQoS) on the subinterface.
Cisco port channel subinterfaces satisfy the first two requirements, and are now extended to provide the third, egress HQoS per subinterface on a port channel, which allows for the shaping of each customer's service (peak information rate) while helping ensure differential treatment of separate traffic classes inside the shaper using low latency queuing (LLQ) or Class-Based Weighted Fair Queuing (CBWFQ).
The following is a simple configuration example.
Interface Gi1/1
Channel-group 1 mode active
Interface Gi2/1
Channel-group 1 mode active
Interface Port-channel 1.100
Encapsulation dot1q 100
Service-policy out hqos

Priority level 1
Class data
Bandwidth percent 30
Class class-default
Random-detect
This feature is available on ES+ line cards only; it is not supported on ES20 or SIP-400 line cards.
Layer 3 QoS Support on CEoP SPAs
When configuring ATM permanent virtual circuits (PVCs) for Layer 3 services such as L3VPN, it is important to have the ability to classify packets on egress based on Layer 3 information and implement CBWFQ or LLQ per ATM PVC. This capability is now available on CEoP SPAs to implement ATM-based Layer 3 services over the following interface types:
• Physical E1/T1 ATM interfaces
• Physical clear channel E3/T3 ATM interfaces
• Channelized E3/T3 carrying logical E1/T1 ATM interfaces
• Channelized STM1 and OC-3 carrying logical E1/T1 ATM interfaces
The following is an example of a configuration.
interface ATM4/1/0.1/1/3/3.100

Mobile and Network Resiliency Enhancements
BFD Scale Improvements for ES+
The Cisco ES+ line cards now offload the generation of the BFD packets from the central route processor, which improves performance and scale substantially. Service providers can improve SLAs with fast detection and save on CapEx at large scale.
The ES+ line cards now support 2000 BFD sessions per system and can achieve 50 ms hello timers. Further enhancements are forthcoming in future releases.
This feature is available only on ES+ series line cards.
BFD IP Static Client Group Support
This feature creates an active parent BFD session to monitor passive child BFD sessions within a group. The parent provides active monitoring for each child in the group. Presence of the static routes tracked through active and passive BFD static configurations depend upon monitoring on the parent BFD session. The hierarchical model optimizes BFD utilization to maximize network efficiency, especially in IP-RAN networks.
BGP IPv6 Client for Single-Hop BFD
The client extends the fast fault detection of BFD to BGP IPv6 deployments.
This feature is available only with SUP-720 and RSP-720 processors.
BFD for RIP v2 Support
This support extends fast fault detection to RIP v2 deployments.
This feature is available only with SUP-720 and RSP-720 processors.
CESoUDP
The Cisco 7600 Series Router already supports CESoPSN to allow customers to transport TDM pseudowires over a MPLS core network per RFC 5086. With Cisco IOS 15.1(2)S, Cisco now supports the option to transport the CESoPSN pseudowires directly over an IP network by using the CESoPSN over UDP IP encapsulation as described in RFC 5086.
This feature extends circuit emulation service support to a general-purpose IP network. Customers benefit with more options for circuit emulation with a simple solution to carry pseudowires over an IP network directly.
This feature is available only with SIP-400 line cards on the Customer Edge-facing side.
CFM Extension for 1+1 Hot Standby Support
Extends Cisco IOS Continuity Check Messages (CFM) to support NSN Microwave 1+1 Hot Standby (HSBY) protocol, extending Cisco's solution offering with NSN, especially in the mobile backhaul applications.
MIB Support for 1588v2 and SyncE
SNMP management of the 1588v2 and SyncE features is now available for complete network timing solutions on Ethernet.
Multicast VPN and IPv6
LFA-FRR for IS-IS
LFA-FRR provides automatic detection and rerouting for alternative paths in networks using IS-IS routing protocols. Open Shortest Past First (OSPF) protocol is planned for future releases. LFA is prefix independent, so convergence on the alternative path is determined in a fixed time.
VRF-Aware DHCPv6 Relay
To facilitate managed central services in MPLS- and VPN-based NGNs, DHCPv6 is now MPLS-aware, so a single resource can be used to serve multiple VPNs instead of dedicating a resource to a VPN. This reduces equipment investment and operational costs.
Because DHCPv6 (relay and server) is now VRF-aware on the Cisco 7600 Series Router, simply providing the VRF context allows the lookup to happen in the specific VRF table for packet transmission to the right destination. VRF-specific capability within DHCPv6 helps provide a highly efficient, managed central service capability, eliminating the need for the service to be replicated on a per-VPN basis.
BGP PIC Edge and Core for IPv6
PIC edge and core simplifies route advertisement processing to scale BGP routing table convergence. PIC edge and core now support IPv6 to provide faster route table convergence at higher scale so that new service opportunities for IPv6 can be delivered with the SLAs that customers expect.
IPoDWDM
Virtual Transponder for Cisco 7600 Series IPoDWDM Line Cards
The purpose of a virtual transponder is to help ensure that the transport management system can continue to manage the DWDM layer as it does today, even when the DWDM transponder is physically integrated into a router line card. DWDM interfaces on the router will appear to the transport management system as transponders housed in separate chassis.
Virtual transponder support for the Cisco 7600 Series delivers an end-to-end management solution for the Cisco 7600 Series IPoDWDM wavelengths deployed over a Cisco ONS 15454 MSTP DWDM network using CTC and CTM. The solution allows management of the Layer 1 parameters of a Cisco 7600 Series IPoDWDM line card from CTC and CTM, including configuration of DWDM parameters (for example, wavelength) and monitoring IPoDWDM port and end-to-end transport status (for example, optical power and OTN alarms).
Virtual transponder is already supported by the Cisco Carrier Routing System (CRS) and Cisco ONS 15454 MSTP and CTP. The addition of this capability on the Cisco 7600 Series provides operators with a common and integrated optical network management solution for Cisco IPoDWDM and Cisco ONS 15454 MSTP and CTP.
This feature is available only on Cisco 7600 Series Ethernet Services Plus Extended Combination (76-ES+XC), 10 GE Extended Transport (76-ES+XT-2TG and 76-ES+XT-4TG) and 10 GE Transport (76-ES+T-2TG and 76-ES+T-4TG) line cards.
IPoDWDM support requires the purchase of the 76-ES+OTN-LIC license.
Video Monitoring Enhancements
Inline Video Monitoring for RTP Metrics
The inline RTP video metrics allow video content and service providers to monitor real-time video quality of multicast and broadcast channels or unicast (video on demand [VoD]) channels on any router port of ES+ line cards at line rate. The metrics available are video loss, jitter, latency and reordered packets. With the distinctive inline RTP video monitoring capability, an external video monitoring appliance or probe is not required. Video monitoring supports multiple video transports, including MPTS, SPTS, MPEG transport stream (MPEG-TS), and uncompressed video (Society of Motion Picture and Television Engineers [SMPTE] standards) and is deployable in these applications: Cisco Telepresence, IPTV, cable video, and video contribution networks.
Video Monitoring Metric Support on Switchport Interface
This release extends the support of all video monitoring metrics to switchport interfaces. All video monitoring metrics can be configured on ingress or egress direction on switchport interfaces and still maintain line rate performance without affecting existing services provisioned on a port.
Video Monitoring Metric Support on PPPoE Interface
This release extends the support of all video monitoring metrics to PPPoE interfaces. All video monitoring metrics can be configured on ingress or egress direction on PPPoE interfaces and still maintain line rate performance without affecting existing services provisioned on a port.
All Cisco video monitoring features are available only on ES+ series line cards. Video monitoring can be configured on any port and still maintain line rate performance without affecting existing services provisioned on a port.
For video monitoring, the purchase of the 76-ES+VIDEO-LIC license is required.
