Drawing network topology in Cisco Prime LMS 4.2

Hi all:
I installed the Cisco Prime LMS 4.2 and managed to discover the Cisco devices and user devices like my PC stations.
Then I tried to draw the network topology from this LMS 4.2 and I found the topology under the Configuration and Monitor tab. By clicking to these two tabs, it appears a page of something like below:
Topology Services
You can use Topology Services to:
- View detailed xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
- Display the physical and logical services in your network
- xxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxx
- xxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxx
- xxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxx
- xxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxx
- xxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxx
There is no action click on this page and it looks like an explanation page and cannot do anything.
May I know how to draw the networl topology by this Cisco Prime LMS 4.2?
Hope to hear the answer from anyone know about this soon. Many thanks!
Warmest regards,
tangsuan

Hi Mantej:
Thanks to your link and I have downloaded the Prime LMS 4.2 document.
I then read and installed the JRE first in 64 bits because my Windows OS is 64bits but it still prompts out the Java installation screen. I then installed the JRE in 32 bits.
After that, it has no more Java installation screen. It then request for downloading file at the Windows top bar. I follow the request to riight click to allow the downloading. The Java running and downlaod the file.
After that, I cannot see any difference. Meaning I still cannot access anything for Toplology Services to draw my network topology diagram.
May I know what should be happen and what is the next step to do the topology drawing?
Many thanks!
Regards,
tangsuan

LMS 4.1 Network Topology Layer 2 view - Re layout map not working

I've finally got Topology Data Collection working on Prime LMS 4.1.
However, when I run Network Topology Layer 2 view and try and re-layout the view to any of the options, Circular, Hierarchical, Symmetrical or Orthogonal, the map never re-draws to that type of layout.It always stays as a mess.
I think it must be a 'feature'.
Any ideas ?
Cheers
Barry

I searched again and didn't find any errors in the same line as the IP or Hostname of the unconnected switches. But I did notice that these switches and all of the devices upstream have "Discovery ani TopoSMFGenerateAbstractTopology" lines where the rest have "Discovery ani TopoSMFGenerateCdpTopology". Do I need to delete everything upstream to the seed device and then rerun a Data Collection? I've included the log. One of the unconnected switches is: 192.168.40.11 Display name: TC160_C. Thanks again.

Network Topology

I have an assignment which requires me to draw a topology of a network. I already able to find out the objects within the network but I still need to know how they (switchs, routers and hubs) are connected to each other (like the route needed to be taken for a pc to connect to the internet). If anybody has any idea or thoughts regarding this I would greatly appreciate it.
Thank you.

Thanks for the reply. After I read in some websites I think JMX is more to the managing of the resources, of course maybe this JMX can be used as an agent to report to one server on where is it, but Actually what I want is a passive way to detect which PC is under which switch or router.. I know this question is more to the networking part, but since you have the experience involves in the same project, maybe you have some ideas..?
The following image is something like what I want.

Creating a network topology with Darwin

Hello,
here are some questions concerning the neural net module at Darwin. I would be grateful if anyone can answer some of my questions:
1. sensitivity analysis: How is importance/sensitivity of each independent variable to the model measured ? (E.g. by measuring the %-increase of the train error if specific variable is taken out of the model ? )
2. Darwin provides the user with three types of activation functions: linear, sigmoid and hypertangent. In a paper with the title "Darwin: A scalable integrated System for Data Mining" , May 14 1997, accessible throug the ORACLE web-sites, some more activation functions have been mentioned : Heaviside, sinusoidal etc. The (most recent) release Darwin 3.7, has only three different activation functions. How can different activation functions be added. I would like to know that, because many application examples from the financial sector used the Gaussian or Radial basis (RBF) function to develop models in financial analysis (portfolio management, prediction of financial crisis etc.)
MOST IMPORTANT QUESTIONS CONCERNING DEVELOPMENT OF NETWORK ARCHITECTURE AND NETWORK TRAINING:
-> Please refer again to "Darwin: A Scalable Integrated System for Data Mining
Overview of Darwin's philosophy, architecture, and functionality for 2.x and 3.x releases, 1997" , May 14 1997, accessible throug the ORACLE web-sites on http://datamining.us.oracle.com/
3. p. 7 : The train and cross-validation mode includes an efficient implementation of the cross validation method for choosing the optimale size of network. It takes advantage of the properties of the error surface, and trains multiple networks with only a marginal increase in time needed for training a single network.
As the notion "Cross-Validation" and especially algorithms using "cross-validation"-techniques to develop a network topology have throughout literature completely different definitions and underlying ideas, may you please explain your understanding of cross-validation by clarifying the algorithm for selection of single-hidden-layer neural net as described above.
4. Learning curve analysis: Does exist a bootstrap loop for the evaluation of a learning curve ? How was the learning curve, as it is presented in the paper above, developed with the aid of a bootstrap-loop explained on p. 11
5. Most recent results in research on generalization performance and its relation to the development of an architecture of a neural net, assume/stress again that overtraining is only an effect of a misspecified, too high machine complexity. Therefore, in this case, conventional training&test-mode is not appropriate for traing a learning machine of optimal complexity.
Consequently, the idea of stopped-training is ambiguous. Only a learning machine with a too high complexity, is capable of approximating the intrinsic noise in the data.
The generalization performance of a learning machine of optimal complexity (i.e.no under-, no overfitting) increases asymptotically without turning point. (in this case: test error decreases asymptotically with the number of training iterations)
Own experiences, results, comments ?
Please note : Following article could answer this question from a more theoretical viewpoint, but hasn't been available to me yet:
Wang, C., Venkatesh, S. S. and Judd, J. S. 1994. Optimal Stopping and Effective Machine Complexity in Learning.
Advances in Neural Networks Processing Systems, G. Tesauro, D. S. Touretzky and T. K. Leen Eds. MIT Press.
Vol. 7, p239.
6. Does Darwin provide the user with a visualization tool in order to illustrate the process of learning by showing network weights? If not, how can this be implemented with the help of Darwin.
This has often been defined as "monitoring" in order to show development of network weights and to make some conclusions.
7. Genetic Algorithms: Can you specify the exact values of the parameters used in the genetic algorithm for network training? E.g. the defined value of the probability of mutation. Please note, that different parameter values (e.g. probability of mutation) used in the genetic algorithm have an effect on the performance of the search for a global optimum .
8. Genetic Algorithm : Why does the g
genetic algorithm has a learning rate ? Normally Genetic Algorithm do not have learning rates, please explain this parameter.
Learning rate are only know for gradient descemt algorithms.
9. Key-field wizzard: How is the importance of an independent variable towards the dependent variable measured ? Which is the underlying correlation coefficient ? The Darwin Help explains the two options to calculate the importance: Gini and cost.
10. E.g. why not use IBM intelligent miner for data preparation instead ORACLE Darwin, because Intelligent miner has two very important processes for data preparation in order to clean data from multi-collinearity:
- factor analysis
- principal component analysis (delivers same results)
null

I have a very similar setup and I'd be happy just to be able to get my MacBook to print to the HP6213!
Are there any guidelines out there for setting up to print to a printer connected to a Windoze infected PC?
btw
I suspect you'd need a printer with a LAN card onboard to be able to print to it without using the Windows machine as a print server.

Prime Infrastructure 2.2 - Network Topology View - Spanning Tree View

Hello Team,
Is it possible on PI 2.2 (latest version) under Maps/Network Topology View to be able to "monitor" the spanning-tree performance?
thanks in advance,
George

Sorry but that's not a currently offered feature.
It would be nice - the Netsys product that Cisco acquired 18-1/2 years ago (and subsequently abandoned) used to do this quite nicely.

How to Identify the Network Topology being used for a running ForeFront TMG Stand Alone array?

Hello Experts,
My client has decided to move their datacenter from one location to other including the ForeFront TMG servers which are being used as Reverse Proxy and TMG Gateway in DMZ environment.
I need to know the network topology used for this configuration so that I could chose the same topology when creating new TMG environment at new datacenter. Here are some details :
1. There are 2 TMG servers configured in a DMZ Workgroup in Stand Alone array.
2. Both servers have 3 NIC attached to them. (one has all public IPs configured, another one has internal IP address and the third one has Management IP which is used to connect the server via RDP).
3. There are more than 50 websites published via this standalone array.
I am very new to Forefront TMG technology and need to know the Topology used to create such environment.
Thanks
Lalit

Hi,
According to your description, you can use the 3-leg perimeter network template and choose which network adapter connects to the LAN, which network adapter connects to the external network and which network adapter connects to the DMZ.
Did you set up TCP/IP settings for the three NICs? If not, please refer to the link below:
Recommended Network Adapter Configuration for Forefront TMG Enterprise Edition Servers

Network Topology for Performance/Redundancy

Hello there,
I am projecting my first Oracle VM Pool for the test the virtualization the many Single Oracle Databases 11Gr2 Standard Edition One, but I have difficult about the network topology best practices.
I have imagined this:
bond0(2x 1gb) - Manament Network and Heartbeat.
bond1(2x 1gb) - Live Migration. ( I want use DRS )
bond2(2x 1gb) - VM Public Network.
bond3(2x 1gb) - VM Manament Network ( Manamgement and Backup for VMs ).
bond4(2x 10GBE) - Storage. ( with Jumbo Frame )
All bonds in active-backup (mode=1)
All ports to be connected to two distinct switchs for redundancy.
Is that correct ?
Any suggestion ?
Best Regards,
Rodrigo.

Cisco PI v2.2 Network Topology Maps

Good afternoon,
I have Cisco PI v2.2 installed on a VM and working fine. I want to add my Network Topology Maps to the main dashboard for ALL users, but I can only see them when logged in as root. How can I get a "standard" user to be able to view these topology maps?
Thanks,
John L.

Dashboards are unique to users. Each user need to set his Dashboard accordingly.
If multiple user's share a common username to login, they should be able to see the same topology map.
In case you want to allow the other users with different roles and groups, you can edit the group they belong to and add Network Topology Map to their permission.
You can see the groups and their permissions under :
Administration > Users, Roles & AAA
Roles who has access to Network Topology: The Network Topology menu will be available to users with below roles:
Admin
ConfigManagers
SystemMonitoring
SuperUsers
Root
-Thanks

Cisco Prime Infrastructure 2.2 - Network Topology error

He dears,
My Customer has installed over UCS Cisco Prime Infrastructure 2.2.
The network is composed with Switches nexus 93962-px and 2960x. All devices were discovered and inventoried successfully.
The problems is that Network Topology is not showing the connections between devices. Some devices connections are showed (partially) and another not.
We've already checked that CDP is run and working fine on all of switches.
I appreciate your help!
Tks,
Regis

I'm sorry to say that but Prime Infrastructure does not support IP SLA functionality similar to Cisco Prime LMS:
http://www.cisco.com/en/US/prod/collateral/netmgtsw/ps6504/ps6528/ps12239/guide_c07-729089.html
It's in the developer's plans but there's no schedule yet for this feature.
It's possible to manually configure IP SLA on the device and then define Custom SNMP templates in Prime Infrastructure and poll whatever information you might consider relevant.
This isn't user friendly (exact OID needs to be typed manually) and is a bit quite complicated, though.
-Thanks
Vinod

CiscoWorks: Using Windows 7, Not able to telnet from Network Topology

I've been looking around the web and I can't seem to find a working solution to get telnet to work from Network topology.
I've enabled telnet and telnet server in the Windows features.
I've put in the reg hack that used to work to get telnet running through IE.
Any of you had any luck in this area?

Network Topology in Campus Manager

I have two switches that are unsupported in my network topology map. These devices show up as green boxes with question marks. The switches are catalyst 3560's model number WS-C3560-48TS. I can see where the 24 port model is supported but not the 48 port. Is there a way to get support for these devices so that my topo map doesn't have green icons with question marks?

Which campus manager service pack do you have installed? This support was added in CM 3.0.4

Creating Network Topology

How to create a network topology in Java usng socket and thread programming.. given a network topology (eg. ring, mesh) in a config file.
Also how to listen and send messages on each channel...
please post some links or sample codes available
Pls reply ASAP
kunal

Java does not have access to IGMP/ICMP and some other info that would be needed.
The network architecture is hidden, on purpose, as it is not needed at the application layer.
You would need to use native code and use its output to guess the topology.
Trace route would help somewhat in connection with ping (ICMP), but if you don't already know the layout, you would have to make assumptions about the design.

What is the difference between physical topology and network topology ,

HI
what is the difference between physical topology and network topology ,
adil

They are tightly linked. The network topology is only interested in the networking links between servers or other actors. A physical topology contains the servers as well as the networking components between them. You might use the term in a different
manner which related to various site's physical attributes such as location but I doubt that's what the document you're working from means.
