Connect Test LAB to Production Network

I have a lab in a remote location, which is, as of now, accesible via console router. I want to connect this to production network, so that i am able to access without the console router. The physical setup would be like
Core --- Distribution ---- AccessSwitch---TestLAB (couple of switch connected to each other)
My concern: if i play in my test lab, there are chances that the broadcasts and STP floods might cripple my production network.
pelase suggest what precautions should i take?

I did a similar thing a while back and I used a firewall to connect to the lab.
So the outside interface of the firewall faced the lab and the inside faced production.
I used a completely different private IP range for the lab and because I didn't want those IPs in the production routing tables I used NAT on the firewall to translate the lab IPs into a spare IP subnet available in production.
You should definitely look to isolate your lab so that nay mistakes are not passed to production.
I wouldn't connect the lab to production with a L2 link because of STP, VTP etc. If you can't go the whole way of a firewall then you should look to use a L3 link if your lab switch supports it.
In addition using a separate VRF for your lab environment would be a good idea so any mistakes if you are playing around with the routing etc. does not affect the global production routing tables.

HT3204 When doing a "Network Connectivity Test" on my PC, as to iStore Connectivity, it says "Secure Link to iTunes Store failed". And when trying to "authorize" my computer to sync ringtones I downloaded to my PC, I keep getting an errot message.

When doing a "Network Connectivity Test" on my PC, while in iTunes, it tells me that "Secure Link to iTunes Store Failed", yet I'm connected to the internet. I was unable to "authorize" my PC with an error message, as well, giving me the code (-3212), saying I was not connected to the internet, yet I am. I can open browser after browser, and navigate just fine. In going through the iTunes Help menu, I am running the tests offered in the drop-downs, but I keep getting the afore-mentioned errors.

With those symptoms, I'd try the following document:

Itunes hanging network connectivity tests

Hi,
I have that old issue with iTunes hanging when I import CD's and the information is retrieved from Gracenotes. It also happens when doing a Network Connectivity Test from the diagnostics tab.
I do not have the jukebox software running as per the old 2011 conversation. Is there anything else I can look at as it is extremely frustrating to have to type things in manually!
Let me know please.
Thanks

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 n above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

We had this problem on 2 machines.
On the 1st machine, we tried the local install option after a few days (Local option with no connect string) and it worked with no problems!
On the 2nd machine, we could never get it to work even after opening a tar with Oracle. Finally we did a remote install from the 1st machine into the database on the 2nd machine. During the remote install while running wfinstall on the 1st machine, we just had to choose the remote option and the database service name for the connect string.
Thanks,
Chethan

*Slow Response on CI SM59 "Connection Test" to Dialog Instance

Our ECP/ECQ, Central Instance runs on UNIX and we have a dialog instance
running on Windows 2003 server. This dialog instance is used ONLY for
running "Archive" jobs to take the load off CI.
The performance of these archiving jobs on the dialog instance has been
extremely slow. When we run the job in CI, on average each document
takes about 1.74s and running on SAP-CONT02 it takes about 7.05s per
document.
When I perform a RFC connection test the logon response time is around
6112 msec.
SAP-CONT02 server has two dialog instances, ECP connected to production
and ECQ is connected to the QA System.
When I perform a similar SM59 RFC test from ECQ CI to ECQ dialog instance the response is 30 msec.
We are not able to utilize the dialog instance to run our archive jobs and it is impacting on the
project delivery. Can you please help to diagnose the issue?

Hi Deepak
Thanks for responding. I believe CI and Dialog are in the separate same network but different subnet mask.
Windows Server: 192.168.205.119
ECQ UNIX Server: 192.168.100.18
ECP UNIX Server: 192.0.11.54
Looks like it might be related to network delay. How do I confirm this? Is there any tests I can perform to prove this? I tried "Note 500235 - Network Diagnosis with NIPING" but it is not much of a help.
Regards
Hari

DSL test lab w/ WIC-1ADSL

Hi folks,
I regularly configure Cisco 800-series routers for field deployment, and I'd love to be able to run through some simulations on the 8x7 ADSL series (837 and 877) in my test lab. I also have a few WIC-1ADSL modules for my 2600/2800 routers.
I know that you can do back-to-back configurations with GHDSL wics, but it doesn't seem to be possible with the internal ADSL modems on the 800's and/or the WIC-1ADSL's.
Can someone please point me in the right direction? I'm looking for the easiest & cheapest way to connect two 8x7's to each other via the ADSL (RJ-11) port, and/or to a WIC-1ADSL.
I'm not necessarily interested in recreating/simulating an entire service-provider infrastructure (yet ;-), my initial goal is just straight connectivity. I'm /not/ familiar with ATM switch or DSLAM specs or configuration, but I'm willing to learn, however I can't spend days and days bringing myself up to speed. Again, getting the connectivity between the CPE devices is primary; the guts of DSL and any required jury-rigging are secondary.
Thanks!

The Cisco 850 series and Cisco 870 series routers support the dial backup function, which allows a user to connect an analog modem to the console port as a backup link to the WAN port in case the ADSL service goes down.

MFP M127fn connected, test printing OK, can't print from applications

Hello Everyone!
I have just set up my M127fn via USB on a Windows 8 system. The set up went fine. I have a small stack of test pages from the HP software, but it won't print anything from any applications like MSOffice. The HP diagnostic software (Print and Scan Doctor 4.6) can communicate with the printer and everything checks out OK.
Any suggestions?
Thanks in advance.

I currently have a WPN824 v3 Netgear router and I'm trying to set up my Apple TV. I'm able to connect it to my wireless network but my airplay feature is currently not working.

I currently have a WPN824 v3 Netgear router and I’m trying to set up my Apple TV. I am able to connect it to my wireless network but my airplay feature is currently not working. The icon does not appear on any of my devices. My ipad and ipones all are currently up to date and are all joined to the same network. Is it the way that my router is configured. Please help let me know what I need to change in my router settings or does my router not work with Airplay. Or is there a simple fix.

you don't mention which products you use
only ipad2 and up support mirror
and only iphone4s and up support mirror
other devices only use airplay for apps which support tvout options

AirPort no longer connects to internet but local networking is fine.

I have an Airport Extreme router version 7.6.3. Recently the router has been dropping connections with my cable modem. I have had to reboot the modem and the router to reconnect. It is no longer connecting to the internet at all. All of my wireless devices can find the Airport and connect to my local WiFi network but no internet access. I tried connecting my macbook directly to the cable modem via ethernet cable and had some of the fastest internet connections in recent memory. How do I make the router work?

If you haven't already done so, install 5.6 utility on your Mac..
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
Leave the package open on the desktop so you can see the file. AirportUtility56.pkg
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. If your Mac refuses to run the software, because it wasn’t downloaded from the Apple store, go to security in preferences and allow other software to work.. this is limitation of trade methinks. You can set back later if you like.
Now drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. in finder, open the new directory, drill down.. applications, utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall version 6 (now 6.3 if you updated) so don't try.. and you cannot or should not run them both at the same time.. although I have had no problems when doing so.
Roll the firmware version back to 7.6.1 or earlier if it will work.. the latest firmware is not the greatest by a long shot.
Then using 5.6 utility you can access the advanced logs on the Extreme.. you cannot do that with v6 utility.
It should show disconnections happening.
You can also access the WAN ethernet settings and set the Airport to 100mbit full duplex.. this seems to have helped people lately.
Of course nothing like this exists in v6 utility.. being a toy utility.

Ipad will no longer connect to my private home network

i have always had my ipad mini connected to my private home network for over a year and just 3 days ago it no longer connects to my network! Why is that and how can i fix it???
i have no problems with my iphone 4s! it still connects to my wifi!

If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPad. Note: Do NOT consider your network to be blameless if some other devices can connect to it.
First, test your iPad on some other WiFi networks: a friends, Starbucks, Barnes & Noble, etc.
If it works well there then the problem is probably with your network. Try restarting your WiFi router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
If your iPad does not function well on other networks it possibly has a hardware problem. You could try Settings > General > Reset > Reset Network Settings to see if that corrects the problem. If not, contact Apple Support or visit an Apple store for evaluation. They can provide a replacement if your iPad is bad.
If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

After setting up my brand new Airport Express 802.11n and accidentally using it to connect my iMac to the network...my iMac no longer connects through Ethernet? Any ideas...I have tried everything without success!!

I have been using Apple technology for about 10 years starting with 1st generation iPods and our house now includes a 5 year old iMac, all versions of iPods and touches, Apple TVs (both generations) and most recently an iPad 2. I have always told family and friends that Apple technology just works. Unfortunately that stopped today. I bought a new Airport Express 802.11n to use for AirTunes around my new pool. I set it up from my iMac and accidentally used it to connect my iMac to the network for a short time. Now I can no longer connect the iMac to the network using a hard wired Ethernet cable. I have tried resetting everything possible, from hubs to routers to the Mac itself and it just will not connect to the network through Ethernet any longer. I am now a very frustrated Apple user especially when the support site says I can't use the fast path support because my product was manufactured 5 years ago...I just bought it at BestBuy yesterday. All other computers and itechnology in the house are connecting via wifi and Ethernet without any issue except from my new iMac boat anchor. Anybody who can help me??? Thanks

John, thanks for the email so quickly.
I too hope I haven't tried "everything" either but I am reasonably technical. I had done what you suggested to do before but I did both again.
Ethernet is yellow in the left side bar. In the right pane it's status says Connected but then below it says "Ethernet has a self-assigned IP address and will not be able to connect to the Internet."
I have tried the assist me menu and Network Status has Ethernet Green, Network settings Yellow, ISP Green, and Internet and Server Red and Failed for both. I have turned things off and on, checked cables, deleted all locations and tried restting them up but to no avail. I even disconnected everything and connected the mac directly into the cable modem itself and the thing still will not connect.
Thoughts???

Ios7 can't connect to wifi ad-hoc network

Hi,
I have a problem connecting my iPhone 4S to the ad-hoc wifi connection my macbook creates when "sharing" the ethernet internet connection through wifi, with iOS6 it worked flawlessy. I have no problems connecting in wifi to my router though.
Anyone experienced that? Could you try?
Thank you

For what it's worth, I contacted the support team at Avatron (the developer of Air Display) and asked whether they had any workarounds. Here's what they came up with:
Thanks for contacting us at Avatron support about the issues that you've been seeing when connecting via an ad hoc network. I was unaware of this problem but after doing some testing this morning it seems to happen with one of our iOS 7 iPad 2s as well.
While this definitely seems like something that Apple needs to address, I was able to get Air Display working over the ad-hoc network if I disabled internet sharing from the Mac System Preferences > Sharing pane. Obviously the drawback of this is that the iPad will no longer be connected to the internet when you are using Air Display in this manner.
Please let me know if this is able to serve as a temporary workaround while Apple investigates the problem.
Cheers,
Aaron
Technical Support
Avatron Software, Inc.
Clearly this is not a full fix as I can't access the internet when connected to my ad-hoc network, but at least I got Air Display running.
Their reply also suggests that this isn't a blanket issue covering all devices running iOS7, as only "one of [their] iOS 7 iPad 2s" was having the same problem.

Xbox 360 does not connect to Airport Express wireless network

I'm at my wits ends. I got a my son a wireless adapter for Christmas and for the life of me cannot get it to work. We have looked at all the discussion forums on the internet and did A LOT of trial and error and still to connection. On one occasion the xbox 360 wireless adapter saw the network and once it tried to connect is dropped.
I have a Wii, two windows PC's, a printer and a PowerMac all connected to my wireless router. The xbox and the Airport Express both have the latest firm ware update.
These are some of the things I have noticed and tested:
1. Connection is Cable Modem>Vonage Router>Airport Express....wireless to Xbox360
2. I have taken the vonage router out to go
Cable Modem>Airport Express...wireless to Xbox360 and still no luck.
3. I was suspecting a double NAT and contacted Comcast to see if I could put the cable modem in bridge mode and they couldn't help me.
4. The network is open (no security)
5. The wireless adapter is a steady red...then when I tell it to find the network it drops out (LED turns off)
6. I have tried to see if I have a double NAT but tracing in the network utility does not show anything.
7. I have tried to place the Airport express in bridge mode and when I updated, it doesn't not come back up and I have to do a hard reset to communicate to it again.
8. There was one instance when the wireless adapter LED was green for about 15 secs and when we tried to connect it dropped out completely (no LED light).
9. I know it works because in the various forums I have read that people have it working.
I called xbox support and they were not very helpful...wouldn't even search similar cases...I have tried everything I could think of and I'm lost any assistance is appreciated.
Victor

Tesserax,
What is the make/model of the Comcast-provided modem? How about the Vonage router? Is this router also wireless? Finally, I assume that prior to introducing the AirPort Express Base Station (AX), the modem & Vonage router were working properly ... correct?
Thanks for your interest in helping me. To answer your questions:
1. The comcast make and model for the cable modem is Scientific American Model#DPX2203
2. The vonage router is ethernet hard wired connected between the cable modem and the apple express wireless route. The vonage router is model#VDV21-VD
3. With the exception of the wireless connection between the Xbox 360 and AX; everything works fine.
4. The AX is running Apple firm ware 6.3
In the discussion I have read of similar problems and have tried them all to no avail. I'm sure the is a fix to this problem because of people in the discussion groups have had the same issues. I don't suspect the wireless router because it has a steady red light and only turns off when we do the network test or scan for networks.
Victor
