Network infrastructure planning advice

I need to set up a new network: "Network A". It needs to have a t1 to "Network B", a backup t1 to "Network B", and a t1 to "Network C". In the near term future there will be a T1 to "Network C" and a T1 to "Network D".
What is a good router configuration for "Network A"? How many routers? What models? What T1s to what routers?
thanks

In addition to ur stated requirements, I would also wish to know what type of connections(Long time, short time) and what is going to be the distance b/w ur Network A and other networks?
Here r the two main WAN connection :
1.For short Distances and long connection times - Leased line is far better.
2.If u want to use shared bandwidth and more efficient packet switching and for Long distances(Long connection times) - frame-relay is good.
Both these technologies provide more than T1 (1.544 mbps) speed connectivity.
Since, u need a T1 backup, ISDN PRI provides this T1 speed connectivity and so u can use it as backup line.It is a circuit switched n/w.

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

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.

What will be tomorrows network infrastructure?

Due to historical reasons, many different network infrastructures co-exist in today's networks, such as Ethernet, SONET, ATM, etc. However, if we are building a complete new infrastructure for a metro or large campus network, which technology would be the most appropriate? What is Cisco Experts opinion?

I would answer this question differently if I were considering the use of the network to be a service providers network or an enterprise network in that I could achieve a different cost model based on single versus multiple customers on the same networks. Also, the end needs of each customer are different, and if they were completely defined could lead to a different cost model for the services rendered.
Generally, a service providers network requires support for TDM and data protocols, requires stringent Service Level Agreements, and generally either owns their own or has a lower cost per mile for fiber than an enterprise. For this reason, a SONET/SDH based network with data capabilities provides the most cost effective way to transport the variety of circuits and streams from the end users location to the point-of-presence (POP) and a WDM system based network is used for the long haul and inter-POP traffic is used. Data can be Ethernet over SONET/SDH or WDM, or it can be done with RPR (802.17).
The enterprise is usually seen as more fiber constrained, and therefore uses a metro WDM (Coarse or Dense) to transport SAN and Ethernet connections between buildings. The ability for the enterprise to convert most legacy traffic into Ethernet, and the ability to combine Ethernet ports into ever-larger trunk speeds, can also lead to very cost effective Ethernet over dark fiber networks up to the new 10 Gigabit per second standard. RPR systems can also be used to extend SONET/SDH recovery mechanisms to Layer 2 and 3 networks.
With voice and video moving to native IP, and the ability to tunnel most other legacy traffic over IP, Metro Ethernet systems over dark fiber, or extended over WDM or SONET/SDH systems are beginning to be the most cost effective way for businesses to connect within the campus or metro today.
The question we have to ask whenever we build a network is what will the next 10 years bring us. My vision is one of lots of devices with wireless mobility, the mixing of SIP and HTTP services to the mobile devices, and lots of high speed Global Area Networking overhead to figure out who and where you are. What is your vision of the traffic and protocols you will be required to support in ten years?

Network infrastructure

HI, I am a person that response to build a network infrastructure in a company. I want to design a good network with high security.
I have a host server (Dell power edge RAM 16)
I want to ADDS, File Server, and Antivirus Server.
How can I user this server in effectively?
Can I user Hyper-V or put the three server together?

Hi,
Microsoft does not recommend installing roles - Hyper-V, File server, AD, DNS roles in a physical server.
Instead you can install only the Hyper-V role on the host and virtualize all of the other roles (DC, DNS, File, etc.).

HT5211 My HP 2355 won't show up in AirPrint? I have it plugged in via USB and set it up on my Mac mini with the airport express network. Any advice?

My HP 2355 won't show up in AirPrint? I have it plugged in via USB and set it up on my Mac mini with the airport express network. Any advice?

Unless your HP printer is an AirPrint-ready device, just connecting it to the USB port of the AirPort Express base station will not make it so.
On the other hand, connecting a non-AirPrint printer to the base station's USB port it can be shared out by the base station's print server. Please see the following Apple Support article for details.

OCS hardware/Network Infrastructure Requirements

Hi,
I was wondering whether anyone was willing to share their current network infrastructure for their OCS deployments.
In terms of type and specs of network cards used by the OCS servers that host the applications?
In addition to this I was wondering whether anyone has used the same windows server to host the web conferencing and voice/fax options or perhaps if this is possible.

E1000 device name in Network Infrastructure

Hi all,
I installed the E1000 router that AT&T provides with U-verse DSL. All works fine except that the device name that appears under "Network Infrastructure" in Windows 7 shows the original default name that Cisco assigned instead of the name I chose. It does not affect operation or performance but looks oddball. I don't see how it can be changed. Does anyone know?
Thanks,

For the E4200, on the Basic Setup page, there's an entry called "Device Name" that I changed from Cisco07933 to E4200. So that's what I see when I look at "Network" on my Windows 7 system. You might have the same or similar setting for your E1000.

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

Hospital Network Infrastructure

Hello,
I need to gather some general information about network infrastructure in hospital. Things like which network devices we need and generally how much load each department creates in our network (e.g. the operation room, the reception, etc.) and how much bandwidth we should allocate to that special room. It would be alo very nice if you tell me how I can calculate the load for each machine (i.e. computer connected to the network). Or any good reference books or websites.
Thank you very much,
Pat

how much bandwidth we should allocate to that special room
I'm no expert with hospital environment but we've started rolling out Gig ports switches with PoE+ support and 10Gb uplinks to the hospitals here. Some of the reasons are the uptake of video streaming and high definition media files that are coming online. Gone were the days when you have to physically look at x-ray templates on in front of a lighted cubicle. Nowadays the films and negatives (ranging from x-ray, ultra-sound, MRI, etc.) are stored in a bank of servers and streamed up to desktop.
Due to the proliferation of wireless we now have to consider putting wireless access points and associated support equipments (WLC/WiSM, WCS, MSE, Wireless VoIP phones and RFID tags).
Due to the nature of hospitals, our switches comprise of 3750E and 3750X with 6500 and Sup720.

Help : Network Infrastructure in a Retail organization (Set-up)

Dear All,
Ok . So this is more of a broad question - but please I need possible idea on how to solve my problem. I haven’t done this before so its more of a high level.
The SITUATION
Ok so theres one established site Company A., (a retail company) in New York, they have all the AD, Exchange ,VPN and all set up. Now they have planned to set up another company B in Texas. This new site would have its own domain
name but they want it to share resources with company A. Ok so these are two different locations.
The QUESTION
Now my question is , in terms of Networking – how would I be able to link these two sites together since they are in different locations(of course I can’t run a fiber OP cable from New york to Texas)
Secondly what would the relationship in terms of domain link? Would it be just trust?
Many thanks all im open to any hint please.
Regards, MassonTech

Hi,
Question 1：how would I be able to link these two sites together since they are in different locations.
I suggest you to use site-to-site VPN connections, such as dial-up line uses short-distance WAN links to your local Internet service provider (ISP) instead of expensive long-distance WAN links. You may reference the link below for detailed information about:
Implementing a Site-to-Site Connection Design:

Branch Office over the Internet：
http://technet.microsoft.com/en-us/library/cc736396(v=ws.10).aspx
question 2: what would the relationship in terms of domain link? Would it be just trust?
If these 2 sites are belongs to different domains, there is a need to create trusts between 2 domains to share resources.

Background Network Heuristic planned for component which it should not be

Hello Expert,
I ran a Network Heuristic in the background without selecting the option "Take into account found components in planning run". However, when the job completed, I review the log and it showed that the components also being planned as well.
Looks like the background planned for components regardless of this option check or not. Please advise
Thanks,
Tom

Hi,
You mean to say that system fully plans the components with or without setting the indicator "Take into account ........".
To me behaviour expected may be as below with additional setting of u201CNet Change planning u201C
Without setting the indicator( "Take into account ......") , System may be only exploding the dependent demand for a BOM level in the first production location found in the planning direction. The dependent demand may be neither covered nor to be propogated further by the supply chain.
With setting indicator, the dependent demands are expected to be covered and furter propogation.

Disaster Plan advice.

Hello all,
I need some suggestion as to how to implement below mentioned strategy.
We have an ERP application running on oracle.
There are 3 servers, one for
Application Server, and two for Oracle.
Oracle is running on 2 node cluster(MSCS & OFS).
In case when there is a power outage, OS level corruption, or any scenario when the production is unavailable, I want some other servers to fail over, both Application Server as well as Oracle.
Options that I'm aware is to have a Standby database, and another Application Server instance running, pointing to standby database.
Backup policy followed is daily Data Dump, daily Incrementally updated backup, and weekly Online Full backup, via EXPDP and RMAN respectively.
My question is,
1- whether Standby Database option is enough to help me plan my DRP, or there other ways to handle this?
2- Other thing is if Standby Database becomes primary, and users start using it, how do I switch back the data to the original primary database?
3- Is it worth to create a dummy database, and have some bat script which'll DROP the user and re-import the schema (unattended) from the backup dump extracted everyday?
4- Is it worth to consider Duplicate Database on another Host option, but then how will it synchronize with production database?
Please advice on the above approach, whether am I on the right direction.
regards,
Luckys

There are a number of business questions to answer before a decent disaster plan can be implemented.
1- whether Standby Database option is enough to help me plan my DRP, or there other ways to handle this?
A standby database can definitely be a component of a disaster recovery plan. Whether it is the only solution, whether you use DataGuard or write your own scripts, and whether there are other options really depends on your environment (Oracle version and edition), the downtime window that is acceptable to the business, the amount of data loss that is acceptable in a disaster, and the business's willingness to invest time and money into developing a solution.
2- Other thing is if Standby Database becomes primary, and users start using it, how do I switch back the data to the original primary database?
You would take a backup of the standby database (which is now the primary) and recover that backup onto the primary machine, making it a standby, then do a switch over to make the primary machine the primary again. This is relatively automated with DataGuard, but is something you would roll yourself if you wrote your own scripts.
3- Is it worth to create a dummy database, and have some bat script which'll DROP the user and re-import the schema (unattended) from the backup dump extracted everyday?
That depends on the window you have to recover the database in a disaster and the business's willingness to lose data in a disaster. My guess is that this would probably not be beneficial.
4- Is it worth to consider Duplicate Database on another Host option, but then how will it synchronize with production database?
I'm not sure what "duplicate database" means here and how (or whether) that differs from a standby database.

How to fax from a macbook on a home network? All advice gratefully received

not sure if i'm being dumb...
i use a macbook on a home Timecapsule/AirPort network, and I want to be able to fax from it. When I try to do so at the moment, I just get 'Modem not found' and am presuming therefore that MacBook does not have any internal modem.
But couldn't Timecapsule do it somehow?
Or do i need to buy/install an additional Apple USB Modem? If so where would I plug it in?
Or do I just need to suscribe to some service such as eFax, which I'd rather not do if possible?
Does anyone know???
All advice gratefully received.

You can buy a modem for you computer, in which case you can connect it to a phone line and the USB port on your computer. There may be all-in-one printers that allow faxing through them, but I am not familiar with which ones have drivers for that. (I so not understand why there would not be, but manufacturers have not always seen it necessary to provide them.) There may be some of those which may be accessed through a network connection to your Time Capsule.

Server and Network Setup Plan - Does this plan sound good and decent??

Well, it's that time again to buy some new hardware. I've already got a decent server that should do the trick, but it's lacking the hard drive space. Now, I've got a few SATA drives but my server system on has IDE controllers. Time to buy some SATA PCI Cards, woot. If you're a hardware junkie, then here are the things I'm planning on buying for the server system. Hopefully now I can give it a new job again.
SATA II 4 port PCI Controller – http://www.newegg.com/Product/Product.a … 6816124008
This thing is only $38.99. I know it's cheap and probably isn't the best out there, but it looks like it'll work fine for my low budget needs. After all, I won't be using the RAID on it until I get 4 matching drives on the card. So, for now it'll do the job.
WD Black 640gb Drives x2 – http://www.newegg.com/Product/Product.a … 6822136319
These are only $74.99 each. A few days ago they were $69.99 and I hate I didn't grab them then, but still pretty cheap for being some of the fastest 7200rpm drives out there.
OCZ Vertex 30gb SSD – http://www.newegg.com/Product/Product.a … 6820227393
Sooner or later I do plan to upgrade all my OS drives to SSD as all the main storage will be transferred over to my server. This should speed up my systems consideribly as their already fast with Arch64 on them.
Later on I plan to upgrade to either two more 640gb drives and add another PCI Controller card or upgrade to 4 new WD Black 1tb drives. My server has two free PCI slots so I'd be able to get a total storage space of around 8tb or something like that.
That's enough for the server hardware and file system setup, here's how I'm planning to roll the network out. Of course, re-designing it from what it is now.
Internet ISP > Modem > Server > Switch and Router > Wired PCs and Wireless PCs
Here are the systems that will be benefiting from the server just for pleasure purposes.
My desktop machine and laptop will have their /home paritions mounted onto the server.
My work machines (iMac and eMac) will have a small /work-data partition mounted onto the server.
My family's machine (XP Pro, wireless) will have a small /family-data partition mounted onto the server with just Read Access to the other partitions just in case. I don't trust them enough not to fuck something over on my machines.
My brother's laptop (Vista Home Premium) will have access to the /data partition for the family.
I believe that should do it for the machines that would need a constant access to it. I'll post any new updates when it happens. Enjoy.

My thoughts exactly. Install a dhcp-server (and maybe bind9) and all you need is a WAP - works here. You could also configure iptables so you don't need an extra machine as firewall.
My concern is that you are planning on putting all data of you and your family (more than 1 TB at the moment) on a machine and that you don't use a hardware RAID-controller. IMHO data is THE most valuable thing (pictures, holiday movies etc.), so I would prefer spending money on a RAID-controller instead of putting it in an SSD. What is you're server going to do that it needs an SSD for its OS? If it's going to serve files and mail, then you won't notice much of a difference with a normal IDE / SATA disk.
I have bought a new pc for my mediaserver, and it's doing practically nothing 90% of the time, but I need it's CPU cycles to transcode 1080p-files to my DLNA-clients on the network. And did you think of a backup-system? I strongly recommend bacula for automated backups - it might be overkill for a home network, but it is not that hard to learn and very, very flexible!
Zl.
BTW: I am still learning a lot about networking, but I do think I know the basics...
