  Viewing IP SLA Responder Service Properties
Viewing IP SLA Responder Service Properties
Cisco IOS Service Level Agreements (SLAs) software allows you to analyze IP service levels for IP 
applications and services by using active traffic monitoring to measure network performance. 
The IP SLA responder is a component embedded in the destination Cisco device that allows the system 
to anticipate and respond to IP SLAs request packets. The responder provides accurate measurements 
without requiring dedicated probes. The responder uses the Cisco IOS IP SLAs Control Protocol to 
provide a mechanism through which it can be notified on which port it should listen and respond.
Two-Way Active Measurement Protocol (TWAMP) defines a standard for measuring round-trip network 
performance between any two devices that support the protocol. 
For information on the devices that support IP SLA Responders, refer to Cisco Prime Network 4.1 
Supported VNEs.
To view IP SLA Responder service properties: 
Step 1In the Vision client, double-click the device configured for IP SLA Responder service. 
Step 2In the Inventory window, choose Logical Inventory > IP  SLA Responder. 
IP SLA Responder properties are displayed as shown in Figure 18-72.

Viewing IS-IS Properties
Intermediate System-to-Intermediate System (IS-IS) protocol is a routing protocol developed by the 
ISO. It is a link-state protocol where IS routers exchange routing information based on a single metric 
to determine network topology. It behaves in a manner similar to OSPF in the TCP/IP network. 
IS-IS networks contain end systems, intermediate systems, areas, and domains. End systems are user 
devices. Intermediate systems are routers. Routers are organized into local groups called areas, and areas 
are grouped into a domain. For configuring IS-IS, see Configuring IS-IS, page 18-150.

  Viewing OSPF Properties
Viewing OSPF Properties
Open Shortest Path First (OSPF) is a link-state routing protocol for IP networks. It uses a link state 
routing algorithm and falls into the group of interior routing protocols, operating within a single 
autonomous system (AS). It uses the Shortest Path First (SPF) algorithm to calculate the best path for a 
given destination. OSPF is perhaps the most widely used interior gateway protocol (IGP) in large 
enterprise networks.
The OSPF topology is a multilink topology, i.e. there can be multiple links from the same OSPF process. 
It is also a single layer and dynamic topology. 
Prime Network supports the following versions of OSPF:
OSPFv2
OSPFv3
Using the Vision client you can view OSPF properties for:
OSPF processes, including the process identifier and OSPF version.
OSPF network interfaces, such as the area identifier, network type, and status.
OSPF neighbors, including the neighbor identifier, neighbor interface address, and status. 
You can view the OSPF topological links for neighbors whose status is Full or Two Way. 
To view OSPF properties: 
Step 1In the Vision client, double-click the device configured for OSPF. 
Step 2To view OSPF processes, choose Logical Inventory > OSPF Processes > OSPF Process (vn) ID where 
vn represents the OSPF version and ID is the OSPF process identifier. 
For example, in Figure 18-75, the entry in the navigation tree is OSPF Process (v2) 10.  System ID Identifier for the neighbor system.
Interface Neighbor interface name.
IP Address Neighbor IP address.
Type IS type for the neighbor: Level 1, Level 2, or Level 1-2.
SNPA Subnetwork point of attachment (SNPA) for the neighbor. 
Hold Time Holding time, in seconds, for this adjacency. The value is based on 
received IS-to-IS Hello (IIH) PDUs and the elapsed time since 
receipt.
State Administrative status of the neighbor system: Up or Down.
Address Family  IP address type used by the neighbor: IPv4 or IPv6.

  OSPF Topology
OSPF Topology
In OSPF topology, the links will be formed among the OSPF Process Device Components even though 
the link signifies the neighborship among them. The OSPF is a multilink topology, thus enabling the 
creation of multiple links from the same OSPF process. From Prime Network 4.3.2, the OSPF topology 
will be added along with the existing support.
The various types of topologies that can be formed under OSPF are
Single layer topology
Dynamic topology
The OSPF topological links are shown for the neighbors which has the Neighbor State as either FULL 
or TWOWAY. For neighbors with TWOWAY state, the OSPF interfaces network type should be either 
BROADCAST or NBMA.
Viewing OSPF Link Properties
To view the OSPF link properties: 
Step 1In the Vision client, right-click on the link between the devices and select Properties to view the link 
properties.

properties.
