Software
The CPT Release 9.5 supports the following software features. You can configure the software features either through CTC or Cisco IOS commands.
Virtual Private LAN Service
Virtual Private LAN Service (VPLS) is a multipoint Layer 2 VPN technology, which allows multiple sites to be connected over a simulated Ethernet broadcast domain that is supported across a provider provisioned IP/MPLS network. In other words, VPLS delivers multipoint Layer 2 connectivity over a Layer 3 network architecture. VPLS evolved as a logical extension of Ethernet over MPLS (EoMPLS), which was developed to enable point-to-point Ethernet-based Layer 2 VPN services.
Connectivity Fault Management
Connectivity Fault Management (CFM) is an end-to-end per-service Ethernet layer OAM protocol. End-to-end CFM can be provider edge to provider edge (PE to PE) or customer edge to customer edge (CE to CE). CFM includes proactive connectivity monitoring, fault verification, and fault isolation for large Ethernet metropolitan-area networks (MANs) and WANs. CFM is defined in the IEEE 802.1ag standard.
Troubleshooting carrier networks offering Ethernet Layer 2 services is challenging. Customers contract with service providers for end-to-end Ethernet service and service providers may subcontract with operators to provide equipment and networks. These networks belonging to distinct organizations or departments are substantially larger and more complex and have a wider user base. CFM provides a competitive advantage to service providers where the operational management of link uptime and timeliness in isolating and responding to failures is crucial to daily operations.
CPT supports the IEEE standard implementation of CFM. It supports CFM over point–to–multipoint bridge domain associated with an Ethernet Flow Point (EFP), Xconnect, and port Maintenance End Point (MEP).
Ethernet Link OAM
Ethernet link Operation, Administration, and Maintenance (OAM) is a protocol for installing, monitoring, and troubleshooting Ethernet MANs and Ethernet WANs. Ethernet link OAM is defined in the IEEE 802.3ah standard.
The Ethernet Link OAM protocol enables service providers to monitor and troubleshoot a single physical (or emulated) Ethernet link. It supports link level verification, monitoring, and troubleshooting between two Ethernet devices.
Synchronous Ethernet
A separate external time-division multiplexing (TDM) circuit is required to provide synchronized timing to multiple remote network elements (NEs) for packet transport networks like CPT. The Synchronous Ethernet (SycnE) feature addresses this requirement by providing effective timing to the remote NEs through a packet network without using an external circuit for timing.
With Ethernet equipment gradually replacing existing Synchronous Optical Networking (SONET) and Synchronous Digital Hierarchy (SDH) equipment in service provider networks, frequency synchronization is required to provide high-quality clock synchronization over Ethernet ports. The SyncE feature provides the required synchronization at the physical level. Operation messages maintain SyncE links and ensure that a node always derives timing from the most reliable source. SyncE uses the Ethernet Synchronization Message Channel (ESMC) to enable traceability of the best clock source to correctly define the timing source and prevent a timing loop. Besides ESMC, CPT also uses the Synchronization Status Messaging (SSM) for time synchronization using Optical Transport Network (OTN) ports.
Match VLAN for QoS
The capability to classify the traffic based on the outer VLAN ID is introduced in quality of service (QoS). The match-all keyword is added to the match command to have a capability to match all the classification criteria present in the QoS class-map.
Remote Ethernet Port Shutdown
The Remote Ethernet Port Shutdown feature allows a service provider edge router on the local end of an EoMPLS pseudowire to detect a remote link failure and cause the shutdown of the Ethernet port on the local customer edge router. Shutting down the Ethernet port on the local customer edge router prevents or mitigates a condition where that router would otherwise lose data by forwarding traffic continuously to the remote failed link, especially if the link was configured as a static IP route.
In-Service Software Upgrade Enhancement
The In-Service Software Upgrade (ISSU) message transformations between the active fabric card and the line card is supported. All the CPT components support the ISSU message transformations between the active fabric card and the line card except the Ethernet Virtual Circuit (EVC) and QoS components.
Bandwidth Management
Bandwidth can now be specified for an Multiprotocol Label Switching Transport Profile – Traffic Engineering (MPLS-TE) tunnel, Multiprotocol Label Switching – Transport Profile (MPLS-TP) tunnel, and a pseudowire. This bandwidth is checked against the available bandwidth. If the specified bandwidth exceeds the available bandwidth, the service cannot be created.
The specified bandwidth is used only for accounting purposes. The specified bandwidth is not reserved by the CPT system for the actual traffic. The bandwidth value is not enforced on the services.
MIB Support
The following Management Information Base (MIBs) are newly supported in CPT 9.5:
CISCO-DOT3-OAM-MIB
CISCO-ENTITY-SENSOR-MIB
CISCO-EVC-MIB
DS1-MIB.my
DS3-MIB.my
ETHERLIKE-MIB
IEEE8021-CFM-MIB
IF-MIB
MPLS-LDP-STD-MIB
MPLS-LSR-MIB.my
MPLS-LSR-STD-MIB.my
RMON-MIB-V1SMI/HC-RMON-MIB
SNMPV2-MIB
For more information on supported MIBs in CPT, see the SNMP chapter of Cisco CPT Configuration Guide.
Node Addition
A MPLS–TP tunnel can traverse through multiple nodes. The Node Addition feature is a CTC enhancement that allows new nodes to be added over an existing MPLS–TP tunnel. If a new node needs be added to the network, the MPLS–TP tunnel need not be deleted or rerouted. Instead, CTC will rediscover the path and re-direct the MPLS–TP tunnels.
Cisco Bug Search Tool
Use the Bug Search Tool (BST) to view the list of outstanding and resolved bugs in a release.
BST, the online successor to Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting. The tool allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The tool has provision to filter bugs based on credentials to provide external and internal bug views for the search input.
The BST is available at Bug Search. To search for a specific bug, go to https://tools.cisco.com/bugsearch, enter the <bugid>. For more information on BST, see Bug Search Help.
Export to Spreadsheet
The Bug ToolKit provides the following options to export bugs to a spreadsheet:
Click Export All to Spreadsheet link in the Search Results page under the Search Bugs tab. Specify file name and folder name to save the spreadsheet. All the bugs retrieved by the search will be exported.
Click Export All to Spreadsheet link in the My Notifications tab. Specify file name and folder name to save the spreadsheet. All the saved bugs in all the groups will be exported.
If you are unable to export the spreadsheet, log into the Technical Support Website at http://www.cisco.com/cisco/web/support/index.html for more information or call Cisco TAC (1-800-553-2447).
