  Configuring IS-IS
Configuring IS-IS
In order to enable IS-IS for IP on a Cisco router and have it exchange routing information with other 
IS-IS enabled routers, you must perform these two tasks:
Enable the IS-IS process and assign area
Enable IS-IS for IP routing on an interface
You can configure the router to act as a Level 1 (intra-area) router, as Level 1-2 (both a Level 1 router 
and a Level 2 router), or as Level 2 (an inter-area router only).
The following IS-IS commands can be launched from the inventory by right-clicking on the appropriate 
node and choosing Commands > Configuration. Your permissions determine whether you can run

Managing Ethernet Networks Using Operations, 
Administration, and Maintenance Tools
Prime Network supports three, interrelated OAM components, including:
Connectivity Fault Management—Connectivity Fault Management (CFM) is an end-to-end 
per-service-instance (per VLAN) Ethernet layer OAM protocol that includes connectivity 
monitoring, fault verification, and fault isolation. CFM allows you to manage individual customer 
service instances. Ethernet Virtual Connections (EVCs) are the services that are sold to customers 
and are designated by service VLAN tags. CFM operates on a per-service-VLAN (or per-EVC) 
basis. It lets you know when an EVC fails and provides tools to isolate the failure. See Viewing 
Connectivity Fault Management Properties, page 19-2 and Configuring CFM, page 19-16.
Ethernet Local Management Interface—Ethernet Local Management Interface (Ethernet LMI) 
operates between the customer edge (CE) and the user-facing provider edge (U-PE) devices. 
Ethernet LMI allows you to automatically provision CEs based on EVCs and bandwidth profiles. 
See Viewing Ethernet LMI Properties, page 19-8 and Configuring E-LMI, page 19-18.
Link OAM—Link OAM allows you to monitor and troubleshoot a single Ethernet link. It is an 
optional sublayer implemented in the Data Link Layer between the Logical Link Control (LLC) and 
MAC sublayers of the Open Systems Interconnect (OSI) model. You can monitor a link for critical 
events and, if needed, put a remote device into loopback mode for link testing. Link OAM also 
discovers unidirectional links, which are created when one transmission direction fails. See Vi ew i n g  
Link OAM Properties, page 19-11 and Configuring L-OAM, page 19-18.
The following topics describe how you can use the Vision client to monitor Ethernet operations, 
administration, and maintenance (OAM) tools. If you cannot perform an operation that is described in 
these topics, you may not have sufficient permissions; see Permissions for Using Ethernet OAM Tools, 
page B-17.

Viewing Connectivity Fault Management Properties 
CFM allows you to discover and verify end-to-end, Carrier Ethernet PE-to-PE or CE-to-CE paths 
through bridges and LANs.
CFM consists of maintenance domains. Maintenance domains are administrative regions used to manage 
and administer specific network segments. Maintenance domains are organized in a hierarchy. The 
administrator assigns a maintenance level to the domain from 0 (lowest level) to 7 (highest level); the 
maintenance level determines the domain’s position within the CFM hierarchy.
CFM maintenance domain boundaries are indicated by maintenance points. A maintenance point is an 
interface point that participates within a CFM maintenance domain. Maintenance point types include: 
Maintenance Endpoints—Maintenance endpoints (MEPs) are active CFM elements residing at the 
edge of a domain. MEPs can be inward or outward facing. They periodically transmit continuity 
check messages and expect to periodically receive similar messages from other MEPs within a 
domain. If requested, MEPs can also transmit traceroute and loopback messages. MEPs are 
responsible for keeping CFM messages within the boundaries of a maintenance domain.
Maintenance Intermediate Points—Maintenance intermediate points (MIPs) are passive elements 
that catalog information received from MEPs and other MIPs. MIPs only respond to specific CFM 
messages such as traceroute and loopback, and they forward those messages within the maintenance 
domain.
NoteThe Vision client does not display information for CFM maintenance endpoints or maintenance 
intermediate points for Cisco Viking devices if errors exist in their configurations. An error in the 
configuration is indicated by an exclamation point (!) in the CLI output. 
For example, if you enter the command 
show ethernet cfm local maintenance-points, a 
configuration error is indicated as follows:
cfm_d100/2 cfm_s100 Te0/2/0/3.110 Up MEP 2100 eb:7a:53! 
CFM uses standard Ethernet frames. CFM frames are distinguishable by EtherType and for multicast 
messages, by MAC address. CFM frames are sourced, terminated, processed, and relayed by bridges. 
Routers support only limited CFM functions. 
Bridges that cannot interpret CFM messages forward them as normal data frames. All CFM messages 
are confined to a maintenance domain and to an S-VLAN (PE-VLAN or Provider-VLAN). CFM 
supports three types of messages:
Continuity check—Multicast heartbeat messages exchanged periodically among MEPs. They allow 
MEPs to discover other MEPs within a domain and allow maintenance intermediate points (MIPs) 
to discover MEPs. Continuity check messages (CCMs) are confined to a domain and S-VLAN. 
Loopback—Unicast frames that a MEP transmits, at the request of an administrator, to verify 
connectivity to a particular maintenance point. A reply to a loopback message indicates whether a 
destination is reachable but does not allow hop-by-hop discovery of the path. A loopback message 
is similar in concept to an Internet Control Message Protocol (ICMP) Echo (ping) message. 
Traceroute—Multicast frames that a MEP transmits, at the request of an administrator, to track the 
path (hop-by-hop) to a destination MEP. They allow the transmitting node to discover vital 
connectivity data about the path, and allow the discovery of all MIPs along the path that belong to

the same maintenance domain. For each visible MIP, traceroute messages indicate ingress action, 
relay action, and egress action. Traceroute messages are similar in concept to User Datagram 
Protocol (UDP) traceroute messages.
From the Logical Inventory tree, you can troubleshoot MEPs using CFM ping, traceroute, MEP status, 
and MEP cross-check status. These commands, and all CFM commands, are described in Configuring 
CFM, page 19-16.
Prime Network associates alarms with the corresponding MEP or global CFM logical inventory objects. 
Prime Network correlates MEP down, MEP up, MEP missing, ETH-AIS, and ETH-RDI events with root 
cause alarms and corresponding tickets that exist along the path between the MEP on the reporting 
network element and the network element hosting the remote MEP.
