Mike,
Thanks for the kind words about the community. It's always nice to hear the things we do make a difference.
Launching a scripting community has come up a few times in the past and I'm open to it. Anyone else have thoughts on this?
On a separate note, you'll be thrilled to hear what one of our CSC booth give-aways will be at Cisco Live San Diego next week. Your best friend the cross-over-cable For those of you out there attending the event be sure and stop by the CSC booth.

Hi,
I have a question...
I going to install two Nexus 7009 with three N7K-F248XP-25 modules on each one, I am planning to create 3 VDC, but at the initial configuration the system does not show the ethernets ports of these modules, even with the show inventory and show module I can see tah the modules are recognized and its status is OK. There is something that I have to do before start to configure these modules...? enable some feature or license in order to see the ports with show running CLI...?

About design and architecture....

where i can find docs or info about design and architecture of a game ????

You could try Gamasutra.com. They tend to have quite a bit about various aspects of game design and programming. Also, you can check this forum for threads on it. Some people have posted questions about designing either specific games within a genre or just specific games and gotten some great feedback (one thread on game design of recent memory is Clue/Cluedo). GameDev.net has some good programming tutorials and chatter to this end also, I'm sure. Just search on here, on the net, and other places, and I'm sure you'll find something.

New to the Design and Animation

I am looking to become a freelance Artist not for animation but Graphic Design and Illustrations. Also what are some good Software programs to render 3D animations and there price range?

There is a reason why Illusion Mage does not appear on that Wikipedia article.
Illusion Mage is the free (GPL) Blender 3D, 'repackaged' and sold to clueless people.
The seller of Illusion Mage has done a good job of keyword spamming Google with articles that look like they are questioning Illusion Mage as a scam. But if you click on those articles, you see bogus glowing reviews that lead to the Illusion Mage web site.
Here are links to truthful information and reviews about Illusion Mage. Illusion Mage is a scam.
3DMagix and IllusionMage, scam or open source leeches?
Illusion Mage & 3D Magix Pro *is* a scam
3DMagix, 3DMagixPro, IllusionMage, scam
From Blender Nation
Illusion Mage is not "used by animation studios worldwide" because animation studios would not be so stupid to purchase software that is already free.
Terry, I would report your post to the moderators to remove as spam but the Adobe forums are ranked highly on search engines. It may have been your worst mistake to mention Illusion Mage here. You've just given yourself and Ilusion Mage some bad internet publicity.

Very New to Graphic Design and Printing

Hi - I have recently gotten into graphic design for print...invitations, etc, and I purchased an Epson R1900 for my studio. This is my first printer purchase and I am also very new to CS5 (self-teaching over the last 2-3 months). So, you can only imagine my printer frustrations...first I had color management issues (still do, but much closer than before due to online research) and now I am trying to load custom paper and print from Illustrator (also using Mac with OSX 10.5.8). I keep getting a message saying "The source selected in the printer driver is not appropriate for the paper that is loaded in the printer." What is going on? I can't have printer issues every time I go to print something!!! Please help me!

In your Applications folder there should be an Epson Printer Utility. You need to change to the custom size there at the driver level and then again in your print dialog when printing the file.
Many problems with Epson Printer Drivers. In my case I could never get the printer utility to show up on my Mac (even after updating drivers, resetting my printers, troubleshooting with Epson, etc). I finally gave up and started using my PC to print to this printer, so I could change to custom size and roll fed.
Good luck.

Help on design and architecture

I have gone through help.sap and found a few things on the object type R3TR and ISFS but am not clear
about the need for ISFS in BI 7, is it that the SAP designers thought when doing migration this object type will help or is it that BI 7 came on top of 3.x as a superior layer or what could be the reason.Experts please enlighten me...
Many thanks

Hi
Until now, DataSources were known as DataSource replicates (object type R3TR ISFS) in the BI system. As of SAP NetWeaver 2004s, a new object concept is available for DataSources. This concept is used in conjunction with the changed object concepts in data flow and process design (transformation, InfoPackage for loading to the PSA, data transfer process for data distribution within BI). The object type for a DataSource from the new concept - subsequently called DataSource - is R3TR RSDS.
If your dataflow is modeled with objects based on the previous concept (3.x InfoSources, 3.x transfer rules, 3.x update rules) and the process design is based on these objects, you can continue to work with 3.x DataSources to transfer data into BI from a source system.
Scope of DataSource Versus 3.x DataSource
3.x DataSource
DataSources were previously known as DataSource replicates (object type R3TR ISFS) in the BI system. The transfer of data from this type of DataSource (referred to as 3.x DataSources below) is only possible if the 3.x DataSource is assigned to a 3.x InfoSource and the fields of the 3.x DataSource are assigned to 3.x InfoSource InfoObjects in transfer structure maintenance. A PSA table is generated when the 3.x transfer rules are activated, thus activating the 3.x transfer structure. Data can be loaded into this PSA table.
DataSource
As of SAP NetWeaver 2004s, a new object concept is available for DataSources. It is used in conjunction with the changed objects concepts in data flow and process design (transformation, InfoPackage for loading to the PSA, data transfer process for data distribution within BI). The object type for a DataSource in the new concept - called DataSource in the following - is R3TR RSDS.
In DataSource maintenance in BI, you specify which DataSource fields contain the decision-relevant information for a business process and should therefore be transferred. When you activate the DataSource, the system generates a PSA table in the entry layer of BI. You can then load data into the PSA. You use an InfoPackage to specify the selection parameters for loading data into the PSA. In the transformation, you determine how the fields of the are assigned to the BI InfoObjects. Data transfer processes facilitate the further distribution of data from the PSA to other targets. The rules that you set in the transformation are applied here.
Hope it helps and clear Now.

NEW TO WEBSITE DESIGN AND MAINTENANCE

Hi. I run my own business and got a friend of a friend to design a website for me. The problem was that when I wanted it updated I was paying £50 each time. I have decided to try and learn how to update the website myself but feel as if I have bitten off more than I can chew. The designer used dreamweaver and he has given me all the information I need to log in to edit the website. What I need to know is this.....is it possible for someone who has never done anything in web design to learn to change text and images on a website and if yes can all of this be done on dreamweaver? I went on to one of these just answer sites and was advised to download FTP and HMTL editor. Do I need to do this as well as dreamweaver? Sorry for all of the questions.

Adding content management, as Nancy suggested as one possible option, can be very costly, although it is the easiet way for non-technical people to maintain a website. Normally content management isn't added after the fact.
Your situation is similar to that of a client of mine. He had a website created by someone who did a nice job, and the client attempted to maintain it in dreamweaver afterwards. For the most part this went OK. The client was able to change names and photos of his staff as they came and went. He was able to update his product offering and so forth. But sometimes, because he had little grasp of HTML and CSS, he made a little mess here and there, so that eventually the site didn't look very nice.
Your site is very simple (that's not a bad thing) so self-maintenance probably would not be overwhelming. Download the trial version of Dreamweaver, spend a few days with a beginning Dreamweaver book, and see if yo still want to go down that road.
It sounds like the designer is willing to cooperate with you, so maybe you can dive in and maintain it in Dreamweaver, calling on the designer for help on an as needed basis.

New to website design and iWeb.

I work in a pediatric clinic and am creating a website for patients to access information in iWeb v3.0.4. I created a Patient Forms page and have several documents available in .pdf format. I want patients to be able to print forms before coming into the office. I setup a link to each of the files on the page and if clicked, takes the vistor away from the page to the .pdf file. The visitor must hit the 'Back' button to return to my site.
Is there a way in iWeb for the .pdf to be displayed without leaving the Patient Forms page?

When you setup the link in the Inspector/Link/Hyperlink pane check the "Open link in new window" checkbox.
Click to view full size
Or if you compress/zip the pdf file and link to the zipped version clicking on the hyperlink will automatically download the file rather than open it in a browser window. This demo page has example links: LinkTestPage

Designing Network Infrastructure

Hi,
I am working on a project to design and implement new data center infrastructure Also migrate users from the old network . The current setup is that network has several vlans and each switch is connected to the main switch via fibre. The new network infrastructure will have two core switches 6509, several 4500 series switches for wiring closet and 3750 switches where the devices will be connected. 4500 switch will be connected to both core switches 6509 via fibre. In this situation, what will be the proper network design? Will appreciate any thoughts.
Thanks

through ur discription i havnt heard from u any thing about the ditribution layer!!
u need the distribution layer befor the core layer
in other words
it should be like
access switches-- distribution --core
basicaly
on the access layer creat all the required vlans but keep them on lyer two
dont make and vlan interface
on the distribution layer
creat the same vlans here layer two
and then creat a vlan interface SVI fopr each vlan
and this vlan interface will be the default gateway for the access switches in the corsponding vlan
next if u want or and u see it required make a core layer
while i think u dont need it
in ur case the distibution layer will be called
distribution/core layer
the link between the access switches and the dist. switches must be trunk
if u want redundancy and high availabilty
u need two dist switches with identical config to some extend
i mean the ip addresing not meant to be the same but in the same ranges with regard to each vlan
and configure hsrp on the dist switches
in the case the default gateway for each vlan access layer user will be the vertiual interface of that vlan hsrp group
also u have to make the active switch in the hsrp group the root switch in the spanning tree config
for dhcp make the ip helper address on each SVI on the dist. switching pointing to a dhcp server and useing the proper VIP for that vlan group as the default gateway
and add the
spanning-tree portfast on each access port that will be a dhcp client
good luck
please if helpful rate

Who to contact Toshiba regarding design and engineering ideas

Hello,
I would like to contact toshiba to open a business talk about new ideas on design and function of laptop computers.
I have drawings and renderings of these ideas.
Can anybody direct me to the right direction?
Thank you.
If you prefer please write me directly: [email protected]

Hello and welcome to this Toshiba community.
It is really nice to have someone here with new ideas and Im really surprised you want to share it with Toshiba.
Is this some kind of top secret stuff? I mean it will be nice to hear what kind of ideas do you have.
For instance I would like to have 18 notebook with two displays placed one behind the other and option to pull one to left and other to right side and use both of them will be nice thing, especially when I use it for my work. Working on two 18 displays but on mobile unit will be simply great thing.
Anyway, it is not easy to give you concrete advice who is the right person for first contact but I know, for example, that marketing division can be contacted in Neuss, Germany. Maybe is this the right address for first contact.
Check a little bit Toshiba Europe support page under http://eu.computers.toshiba-europe.com
Maybe you will find something useful there.
Bye

Firewall/Switching/VLAN Design and Security considerations

Hi,
Consider the following:
/SW3---|
External--S1--FW---/ |Subnet 1
| \ \ |
| \__\SW4---|
| /\
| / /SW5--|
External--S2--FW-/ |Subnet 2
\ |
\SW6--|
Requirements:
Router/Switch/Firewall/NIC resiliency. We can pretty much cover this with HSRP/redundant links(STP)/HA between firewalls/ and (HP) NIC Teaming.
Question:
Is it unreasonable to have SW3-SW6 physically on the one switch due to lack of available ports?
I take it this wouldn't be the securtiy purists choice of implementation?
If it is reasonable/doable, what are the features on IOS on switches eg. 2950's to implement this?
Any help appreciated.
Thanks
Mark

You can configure network security by using ACLs by either using the Cluster Management Suite (CMS) or through the command-line interface (CLI). You can also use the security wizard to filter inbound traffic on the Catalyst 2950 switches. Filtering can be based on network addresses or TCP/UDP applications. You can choose whether to drop or forward packets that meet the filtering criteria. To use this wizard, you must know how the network is designed and how interfaces are used on the filtering device.

Hi Marcelo,
Yes, there are some requirements for certificates in Expressway.
Expressway Core (Exp-C)
- Can be signed by either External or Internal CA
- Better to use a cluster name even if you start with 1 peer in Exp-C cluster. In the future, if more peers are added, changes would be minimal.
- Better to use FQDN of cluster as CN of certificate, this way the traversal zone configuration on Expressway-E won't require any change even if new peers are added to Exp-C cluster.
- If CUCM is mixed mode, include security profile names (in FQDN format) as Subject Alternate Names
- The Chat Node Aliases that are configured on the IM and Presence servers. They will be required only for Unified Communications XMPP federation deployments that intend to use both TLS and group chat. (Note that Unified Communications XMPP federation will be supported in a future Expressway release). The Expressway-C automatically includes the chat node aliases in the CSR, providing it has discovered a set of IM&P servers.
- For TLS b/w CUCM, IM-P & Exp-C
+ If using self-signed certificates on CUCM, IM/P. Load Cisco Tomcat, cup, cup-xmpp certificates from IM-P on Exp-C. Load callmanager, Cisco Tomcat certificates from CUCM on Exp-C.
+ If using Internal CA signed certificates on CUCM, IM/P. Load Root CA certificates on Exp-C.
+ Load CA certificate under tomcat-trust, cup-trust, cup-xmpp-trust on IM-P.
+ Load CA certificate under tomcat-trust, callmanager-trust on CUCM.
Expressway Edge (Exp-E)
- Signed by External CA
- Configured Unified Communications domain as Subject Alternate Name
- If using a cluster, select FQDN of this peer as CN and FQDN of Cluster + this peer as Subject Alternate Name.
- If XMPP federation is being deployed, enter the same Chat Node Aliases as entered in Exp-C.
For more details, please refer to the Certificate Creation Guide for Cisco Expressway x8.1.1

Howto test new or modified network infrastructures with standardized testing methods?

Hi,
I'm sure many of you regularly do tests of new or modified network infrastructures before going live. And you developed detailed plans and schedules how to test, how I did too.
Does anybody know if there exist standardized testing methods for this cases?
Like recommendations how to check features, performance, hardware failures, convergence times, software updates, network management etc.?
Does Cisco offer information concerning that?
Especially for software testing there exist many methods to check if it's working properly, but for technical it infrastructures I did not find any informations.
Best Regards
Thorsten

I guess you are looking for something like this -
http://www.ciscopress.com/store/enterprise-network-testing-testing-throughout-the-network-9781587141270
should say I don't own the book or have ever read it.
I have never come across a set of standardised testing methods in the same way software has but that's is not particularly surprising when you consider networking as an industry is a long way behind other parts of IT in that respect.
We are all still using CLI for most of our jobs :-)
I suspect with SDN that there will be a far more extensive range of testing tools available in the long run but we aren't there yet.
Personally I do pretty much what you already have. When I was involved in design we had proof of concept labs where we could test it would actually work and which often fed back into the design.
Then we had to test it with the existing production environment to see how it impacted on what we already had.
If all that went well we then pretty much knew what tests we needed to run when we implemented it into production.
