Cisco MPLS Diagnostics Expert is a new product option for ISC 4.1. It provides automated troubleshooting and diagnostics of connectivity problems in MPLS/BGP VPNs. Cisco MPLS Diagnostics Expert reduces service downtime and minimizes operational costs by automatically localizing and diagnosing connectivity problems in your network. It is explained in the new Cisco MPLS Diagnostics Expert 1.0 User Guide on ISC 4.1.

Discovery

Discovery modules have been integrated together into a discovery workflow, controlled and monitored from the web GUI. To find the discovery workflow, you can navigate to Service Inventory > Discovery. All of Discovery is explained in the new chapter, Service Inventory > Discovery, and the new appendix, ISC XML Reference, in Cisco IP Solution Center Infrastructure Reference, 4.1. In addition to the new MPLS VPN Service Discovery and improved role assignment, the following features are supported:

File based device discovery

Rules based device role assignment

Workflow status, logging, and monitoring GUI to keep track of progress for various discovery stages

Bulk creation of Customer, Site, Provider, and Region objects through an XML data file.

Discovery—L2VPN/VPLS Service Discovery

Enhanced for this release, the L2VPN Service Discovery module builds upon existing functionality and has been integrated into the Discovery process. The L2VPN Service Discovery component supports the ability to:

discover point-to-point services, such as Ethernet Relay Service (ERS) and Ethernet Wire Service (EWS), and point-to-multipoint services, such as Ethernet Multipoint Service (EMS) and Ethernet Relay Multipoint Service (ERMS).

discover EMS and ERMS (VPLS EWS and ERS) services on MPLS and Layer 2 cores.

modify the service intent and use the GUI to specify Customers and VPN information.

modify the discovered Layer 2 VPNs and related information.

ISC 4.1 does not support L2TPv3 Service Discovery.

Discovery—MPLS VPN Service Discovery

The MPLS VPN Service Discovery module is new for ISC 4.1. It adds support for the discovery of MPLS VPN services. This module can be optionally included or excluded in the discovery process. The MPLS VPN Service Discovery component supports the following features:

Discovers all VPN topologies (full mesh, hub-and-spoke, and partial mesh).

MPLS VPN Service GUI allows you to view and modify the discovered MPLS VPNs and related information.

Allows normalization of partial mesh VPNs for integration into ISC's repository.

Documentation

All ISC 4.1 documentation is available by navigating from http://www.cisco.com/univercd/cc/td/doc/product/rtrmgmt/isc/4_1.

The newly purchasable Cisco MPLS Diagnostics Expert application is explained in Cisco MPLS Diagnostics Expert 1.0 User Guide on ISC 4.1.

The new Metro Ethernet functionality is explained in Cisco IP Solution Center L2VPN User Guide, 4.1 and Cisco IP Solution Center Quality of Service User Guide, 4.1.

The completely revised Discovery functionality is described in the new chapter, Service Inventory > Discovery, and the new appendix, ISC XML Reference, in Cisco IP Solution Center Infrastructure Reference, 4.1.

Descriptions of more system error messages are in Cisco IP Solution Center System Error Messages, 4.1.

Each of the new features and changes of behavior based on Cisco Defect and Enhancement Tracking System (CDETS) fixes is explained in the appropriate manual.

Inventory Manager

In previous releases of ISC, Inventory Manager was implemented as a Java Web Start application. In ISC 4.1, this approach is obsoleted and the current implementation of Inventory Manager is web-based (Web-IM), explained in Cisco IP Solution Center Infrastructure Reference, 4.1. Web-IM supports bulk device configuration importing and editing features. The Discovery related features found in previous releases of Inventory Manager have been integrated into the Discovery workflow discussed in the "Discovery" section.


Note The Topology Tool still uses Java JRE and Java Web Start. Requirements for these are still in effect for the Topology Tool.


Metro Ethernet Support

ISC 4.1 provides several features that enhance the provisioning of Metro Ethernet services, explained in Cisco IP Solution Center L2VPN User Guide, 4.1. These features include the following:

VLAN Translation—VLAN translation is available with the Cisco 3750-ME switch and with the Cisco 7600. While editing the L2VPN Ethernet Relay Service (ERS) policy or Service Request creation, you can enable one-to-one or two-to-one VLAN translation. This support is for L2VPN only.

Storm Control Settings—Storm control settings are now available for broadcast traffic, multicast traffic, and unicast traffic.

Enhanced Policy for VC Attributes—During L2VPN or VPLS Service Request creation, you can manually enter a virtual circuit ID (VC ID).

SUP 720 Support—You can now support L2VPN on the Cisco 7600 by using the SUP 720. The Optical Service Module (OSM) card is no longer required. The SUP 720 is only supported for L2VPN.

3750-ME Platform Support—L2VPN and VPLS are supported as a U-PE and L2VPN is supported as an N-PE on the 3750-ME.

UNI Port Security—This feature is optional and editable.

MPLS Enhancements

ISC 4.1 provides the following feature enhancements and is explained in Cisco IP Solution Center MPLS VPN User Guide, 4.1:

Residential Services allows data, voice, and video using a Metro Ethernet Access Domain into an MPLS VPN.

eBGP as PE-CE routing protocol for a No CE policy.

Support of the Cisco 7600 and Cisco 3750 as an N-PE with VRF termination on a subinterface or a Switch Virtual Interface (SVI).

UNI port security.

Oracle Support

ISC 4.1 supports the following, which is explained in Cisco IP Solution Center Installation Guide, 4.1:

Oracle database has been tested with Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - 64 bit Production. If you would like to use another version of Oracle, see Oracle's compatibility information.

Oracle logical standby.

Quality of Service (QoS) Enhancements

In ISC 4.1, Quality of Service (QoS) has been enhanced to support the following:

Metro Ethernet 3.1 solution, including hierarchical QoS support for the Cisco 3750-ME switch as a U-PE and QoS support for the Cisco 7600 as a U-PE, as a U-PE and PE-AGG, as a U-PE, PE-AGG, and N-PE, and as a U-PE and N-PE. This is explained in Cisco IP Solution Center Quality of Service User Guide, 4.1.

Cisco 12000 (GSR) Series new line card support for IP QoS.

Reporting Enhancements

Many of the MPLS VPN and L2 VPN reports supported by API are now available in the GUI. These are explained in Cisco IP Solution Center L2VPN User Guide, 4.1 and Cisco IP Solution Center MPLS VPN User Guide, 4.1.

Repository Migration and Upgrading to ISC 4.1

VPNSC 1.x or 2.x users must first migrate from VPNSC to ISC 4.0. After installing ISC 4.1 and pointing to your migrated VPNSC repository, you must run the ISC 4.1 upgrade tool. VPNSC customers are encouraged to contract the services of Cisco's Customer Advocacy Global OSS/NMS Practice. They provide migration services for VPNSC customers that want to migrate to ISC. Contact your local account representative for more information and have them send e-mail to isc-rapidresults@cisco.com, or you can contact the ISC marketing team at isc-mktg@cisco.com.

ISC 3.0 and ISC 3.1 users must contact ISC Marketing, e-mail: isc-mktg@cisco.com, to upgrade to ISC 4.1

ISC 3.2 users must upgrade to ISC 3.2.2 running the appropriate upgrade script (dependent on whether you have a Sybase or Oracle database) prior to installing ISC 4.1. Then you must run the ISC 4.1 upgrade tool.

ISC 3.2.2 or later users must install ISC 4.1 and then run the ISC 4.1 upgrade tool.

The upgrade scripts are all found at http://www.cisco.com/cgi-bin/tablebuild.pl/isc.

This is all explained in Cisco IP Solution Center Installation Guide, 4.1.

Traffic Engineering Management Enhancements

In ISC 4.1, Traffic Engineering Management (TEM) has been enhanced to support the following, which is explained in Cisco IP Solution Center Traffic Engineering Management User Guide, 4.1:

Multi-vendor awareness

IOS-XR devices with IOS-XR Release 3.2

Limitations and Restrictions

This section sets the expectations correctly for how to use the following features:

Acronym and Terminology Rule Enforcement

Cisco MPLS Diagnostics Expert

Discovery

Discovery—L2VPN Service Discovery

Discovery—MPLS VPN Service Discovery

Inventory Manager

Metro Ethernet Quality of Service (QoS)

Number of Concurrent GUI and Northbound API Users

SUP 720 Support

Traffic Engineering Management Configuration Auditing

VLAN Translation

Acronym and Terminology Rule Enforcement

The new terminology introduced in this release does not check to ensure the contents of a device type. For example: PE-AGG is by definition for aggregation only and no UNI should be allowed, but a UNI can be provisioned in this case in ISC.

Cisco MPLS Diagnostics Expert

To use Cisco MPLS Diagnostics Expert, it is imperative that the PE routers have a Cisco IOS image that supports the Cisco OAM functionality. MPLS Diagnostics Expert does not troubleshoot routing protocols, IP connectivity within the core, inter-Autonomous Systems (AS), Carrier-Supporting-Carrier, or traffic engineered MPLS cores.

Cisco MPLS Diagnostics Expert supports Telnet and SSH as transport mechanisms between the ISC server and the devices being managed. Cisco MPLS Diagnostics Export does not support CNS as a transport mechanism.

Cisco MPLS Diagnostics Expert supports only Layer 3 MPLS VPN diagnostics.

Discovery

When using common Discovery modules, keep the following in mind:

Discovery can only occur once in an ISC repository's lifetime. No incremental device discovery or service discovery can occur.

Only one user at a time should access the Discovery Workflow page and run Discovery. If more than one user accesses the process, errors occur.

Discovery—L2VPN Service Discovery

L2VPN Service Discovery supports:

services on PEs but not on CEs.

discovery of an MPLS or an Ethernet core but not both.

Discovery—MPLS VPN Service Discovery

In discovered VPNs, it is possible that some of the links (with unmanaged CEs) will have dummy customers associated. The Service Discovery does not associate a customer to DISC_VPN if one or more links are unmanaged. Therefore, you must manually assign a customer for that VPN in the MPLS VPN Service Discovery GUI.

Inventory Manager

The following restrictions apply to Inventory Manager:

You cannot change the Provider for an existing PE or the Customer for an existing CE. If you try to open CEs or PEs, the Customer and Provider, respectively, show that they are editable but the changes you make are not saved in the repository.

The bulk interface marking feature and Interface Marking Rule Editor found in previous releases of Inventory Manager have been removed. Interfaces can be marked by using the device editor in ISC.

Device config files must exist on the ISC server.

Metro Ethernet Quality of Service (QoS)

For the 3750-ME, ISC supports User Network Interface (UNI) to Network-to-Network Interface (NNI) traffic. It does not support locally switched traffic.

For Metro Ethernet on the 7600, ISC supports Ethernet Virtual Circuit (EVC) and EVC + COS class of service identifiers. It does not support the EVC + Differentiated Services Code Point (DSCP) class of service identifier.

Number of Concurrent GUI and Northbound API Users

Current testing of ISC 4.1 indicates that one standalone ISC system can support a maximum of 25 concurrent users on a system with more than 10,000 attachment circuits.

SUP 720 Support

If an N-PE is part of a layer 2 ring, an L2VPN service cannot be supported on the SUP 720 without OSM.

Traffic Engineering Management Configuration Auditing

Configuration auditing for Traffic Engineering Management (TEM) does not support the following commands:

path-option

next-address

VLAN Translation

VLAN translation is supported on L2VPN not on VPLS.

Important Notes

1. All ISC patches are available at: http://www.cisco.com/cgi-bin/tablebuild.pl/isc.

2. The supported Sybase and Oracle databases behave differently. All GUI queries are case insensitive for Sybase and case sensitive for Oracle.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
