19-17 Cisco Prime Network 4.3.2 User Guide Chapter 19 Managing Ethernet Networks Using Operations, Administration, and Maintenance Tools Configuring CFM Command Description Maintenance Domain> Configure CFM Maintenance DomainA maintenance domain is a management space for the purpose of managing and administering a network. A single entity owns and operates a domain and is defined by the set of ports internal to it and at its boundary. Each maintenance domain can contain any number of maintenance associations. Each maintenance association identifies a service that can be uniquely identified within the maintenance domain. The CFM protocol runs within a particular maintenance association. Using this command, assign a unique maintenance level to each domain and a maintenance endpoint archived hold time. Maintenance level defines the hierarchical relationship among domains and MEP Archive Hold time acts as a demarcation point on an interface that participates in CFM. Global Parameters > Configure CFM Global ParametersEnable CFM globally for a network element. Using this command you can configure the device to transmit traceroute and loopback messages with a hold-time value that indicates the validity of the messages. Enable> Cisco> Continuity Check > Configure CFM Continuity Check Enable> Cisco> Continuity Check> Enable CFM Continuity CheckEnable continuity check parameters on the specified domain, service 1, bridge group, and bridge domain names. MIP > Configure CFM MIPThe Configure CFM MIP command configures an operator-level maintenance intermediate point (MIP) for the domain-level ID. If the port on which a MIP is configured is blocked by Spanning-Tree Protocol (STP), the MIP cannot receive CFM messages or relay them toward the relay function side. The MIP can, however, receive and respond to CFM messages from the wire. A MIP has only one level associated with it, and the command-line interface (CLI) does not allow you to configure a MIP for a domain that does not exist. Service ID> Configure CFM Service IDUse the Configure CFM Service ID command to configure the CFM service ID.

Your permissions determine whether you can run these commands (see Permissions for Using Ethernet OAM Tools, page B-17). To find out if a device supports these commands, see the Cisco Prime Network 4.3.2 Supported Cisco VNEs. Configuring L-OAM The following Link-OAM commands can be launched from the inventory by right-clicking and L-OAM node and choosing Commands > Configuration. Your permissions determine whether you can run these commands (see Permissions for Using Ethernet OAM Tools, page B-17). To find out if a device supports these commands, see the Cisco Prime Network 4.3.2 Supported Cisco VNEs. MEP> Configure CFM MEPUse this command to configure maintenance endpoints (MEPs), which have the following characteristics: Per-maintenance domain (level) and service (S-VLAN or EVC) At the edge of a domain, define the boundary Within the bounds of a maintenance domain, confine CFM messages When configured to do so, proactively transmit CFM continuity check messages (CCMs) At the request of an administrator, transmit traceroute and loopback messages Enable> Cisco> SNMP Server Traps> Enable CFM SNMP Server TrapsEnables Ethernet CFM continuity check traps and Ethernet CFM cross-check traps 1. Applicable for Cisco ASR 9000 series that run on Cisco IOS XR software. Command Description Command Description Enable > Global E-LMIEnable Ethernet LMI globally. Enable On InterfaceIf E-LMI is disabled globally, you can use this command to enable E-LMI on specific interfaces. Configure MultiPoint To MultiPoint or Point To Point EVCUNI count indicates the range of the Unified network interface(UNI) is 2 to 1024; the default is 2. If you enter a value of 2, you have the option to select point-to-multipoint service. If you configure a value of 3 or greater, the service is point-to-multipoint. Configure UNI in an Interface Configure Service Instance Vlan Id on InterfaceSpecify the service interface ID (Per-interface Ethernet service instance identifier that does not map to a VLAN).

CH A P T E R 20-1 Cisco Prime Network 4.3.2 User Guide EDCS-1524415 20 Monitoring Carrier Grade NAT Configurations Carrier Grade NAT is a large-scale Network Address Translation (NAT) that provides translation of millions of private IPv4 addresses to public IPv4 addresses. These translations support subscribers and content providers with a bandwidth throughput of at least 10 Gbps full-duplex. Carrier Grade NAT addresses the IPv4 address completion problem. It employs Network Address and Port Translation (NAPT) to aggregate many private IPv4 addresses into fewer public IPv4 addresses. For example, a single public IPv4 address with a pool of 32,000 port numbers supports 320 individual private IP subscribers, assuming that each subscriber requires 100 ports. Carrier Grade NAT also offers a way to implement a graceful transition to IPv6 addresses. To route internal public addresses to external public addresses, a VPN Routing and Forwarding (VRF) instance is created. Interfaces are created for the VRF at the subscriber-side (private) and the Internet-side (public). The VRF enables static or dynamic routing of protocols on the interfaces. Prime Network supports the following instances for Carrier Grade NAT: Stateful Address Translation- NAT44 Stateful Stateless Address Translation- NAT 64 Stateless (X-LAT) IPv6 rapid deployment (6rd) Each Carrier Grade NAT instance has several attributes listed under them, such as preferred location, address pools, associated interfaces, and statistics. The attributes are grouped under related categories. The categories and attributes are listed below: NoteIPv4 Network Address Translation (NAT44) is not supported for devices running Cisco IOS XR software version 4.1. For information on the devices that support Carrier Grade NAT, refer to Cisco Prime Network 4.1 Supported VNEs. The following topics describe how to use the Vision client to view Carrier Grade NAT properties. If you cannot perform an operation that is described in these topics, you may not have sufficient permissions; see Permissions for Managing Carrier Grade NAT, page B-16.
