Does VTP can cause disturbance in the network?

Dear All,
We have existing setup where VTP is configured. I am adding new switches with same VTP domain and in client mode. Does this can cause any disturbance?
Also, If I dont configure any VTP domain on new switches and connect as it is to network which has VTP domain configured, any effect on the network?
Thank You,
Abhisar.

My understanding of VTP, is different from Leo's, at least for V1 or V2. I believe, yes, a VTP (V1 or V2) client could overwrite your (shared) VLAN database.
For new devices, that are to be VTP V1/V2 clients, insure sever's database revision is > 0, and before connecting new device to network, set new device to transparent, set other VTP parameters, add device to network, then set to client. Client should then get copy of database via trunk from an upstream VTP (server/client/transparent) device in configured domain.
Regarding OP's 2nd question, "null" domain V1/V2 devices will pick up configured VTP domain names, from other devices, but I'm unsure of all the conditions. Would suggest you follow prior paragraph.
PS:
VTP V3 is resistant to its VTP clients "accidentally" resetting the shared VLAN database.

Upgrade ip5 to ios6.0.2 and now I can't connect to the network (was fine with 6.0.1).

I just upgraded my ip5 to ios6.0.2 and now I can't connect to the network (was fine with 6.0.1). I bought the phone online in Canada but have a Hong Kong simcard. Any solution to connect to network?

I bought mine in the US and activated using a German SIM. It worked fine first on 6.0.1. After upgrading to 6.0.2 the SIM does not work. I have reset the reset the phone and still does not work. I loaded a new SIM and the phone worked for few minutes before going to Searching mode after I restarted the device. I am being told by the Genius Bar team that this is a Hardware failure.

WRT54GX2 does not pick up time from the network...

I have a WRT54GX2 running firmware 1.01.14 and it does not pick up time from the network. I have PacBell (now AT&T) as an ISP and a DSL link. My old Netgear router picks up the time immediately. I am trying to figure out if I have a defective unit or if this is a firmware bug. Without the time, I can not use any of the scheduling functions, nor measure uptime.
Does anyone have this router with the time working? I have set the appropriate time zone.
Thanks,
Martin

Thanks for you ideas.
The backup file appears to be binary. However in searching through it I did see 3 time related text strings, namely: clock.stdtime.gov.tw, time-b.nist.gov and time.nist.gov. I can successfully ping clock.stdtime.gov.tw and time.nist.gov. This reinforces my belief that my ISP (AT&T nee PacBell) is not blocking access.
however ntp works on TCP port 123. ping works on udp 7 afaik. if your old netgear works i guess this is a router problem.
have you reset the router yet? afaik press reset button for 10 seconds.
you will however loose all settings and need to enter them again. it may however fix the issue.Message Edited by linksysinfo on 07-09-2006 03:09 AM

Upgrading to xcode and can't connect to the network

Hi! I use a C++ library in my application which connects to the network (I suppose it uses sockets). I've been using it for months and I was using xcode 3.2.4. Now, I just had the great idea of upgrading to xcode 3.2.5, and I found out my application was crashing with the error:
If you are encountering this problem running a simulator binary within gdb, make sure you 'set start-with-shell off' first. 3.2.5
Ok, couldn't solve it, so went back to 3.2.4, as suggested somewhere. The application is not crashing anymore, but now the library can't connect anymore to the network. Tried to rebuild it (I didn't write the library but I have the sources) and use the new library, but nothing. Still the library can't connect to the network. I tried with every simulator.
Any idea what there could be wrong and how I may be able to solve this? Can I somehow delete manually everything related to xcode and the simulator and try to start all over again?
Thanks!

I've been able to temporarily solve this problem by removing the entire Development directory and installing again xcode 3.2.4. Even with xcode 3.2.4 however, the same happened, and I had to do this procedure again. Now it seems to be working correctly, but it seems something very strange has happened. Hasn't anyone experienced anything similar?
Thanks!

OS 10.3.9 and Windows 2003 Server - Can't get to the network

My company just up graded from a Windows 2000 to a Windows 2003 server. I am lone Mac user. Yesterday, with Windows 2000, I had no trouble accessing several drives on the server. Now with this upgrade, I can't log on to any of the drives.
The IT folks are not that Mac savvy and they've tried a few things regarding security, but they're lost, and haven't found anything from Microsoft that helps. And I know nothing about networking. I've tried searching Apple but can't find anything specific to this problem. I can print to all the networked printers, just can't get to the drives.
Is there something we're missing here? Something in my System Preferences that we needed to adjust first?
Thanks.

Try resetting your modem. Power it down. Wait a moment, then power it up again. While it resets, do not change what is connected to it.
In another, though unrelated article, Apple recommends the following:
If you have configured your Wi-Fi base stations in the past, it may be helpful to do a factory default reset of each Wi-Fi base station that will be part of the wireless extended network before you begin.
This step really ought not be considered optional for the configuration you propose. If the problem persists after resetting your modem, reset everything else too.

HT3576 how can i verify that the network or firewall is not blocking access to port 5223.

Talk to someone who knows something about networking and/or firewalls on an appropriate forum.
Configuring your network and/or firewall is beyond the scope of this forum, which is devoted to issues using the iPhone.

I PAD 2 won't activate to itunes - can't connect to the network

i'm trying to activate my ipad2, i'm using windows software operating systm. i keep receiving a message that says itunes can't connect to the network, check settings. i'm having no problems with internet. won't let me install itunes 10.1

As I understand it, you already have iTunes for Windows version 10.2.1, and you're running Windows Vista Home/Premium on an HP.

HT4356 My iPad does not see my printer on the network. The printer says it is connected and I can ping it from my pc, but the iPad does not seem to be able to find it. I am going though an AOL supplied router, I have read this can cause issues, is this

I am trying to print from my iPad to a HP 3520 printer using AirPrint. I have connected the printer to my local wireless network and it confirms it is connected. However my iPad can not find the printer on the network when it searches for it. I am using an AOL supplied router and have read reports that this can cause problems. Is this the case? How do I resolve this issue?

Hi,
That indeed can be caused by a router as Apple's AirPrint uses Bonjour to communicate with the device.
Bonjour Services relies on IP Multicasting which have to be supported by your network.
To isolate the problem, please follow the steps below to enable Wireless Direct and directly connect the iPad to your printer (which means without using the router).
Once the iPad connected to the Wireless Direct network try printing and check for any difference.
If the printer can be found via the temporary connection but not through your router that indicates lack of Multicast support or wrong configuration of your router.
In such a case be sure to contact AOL and check if the router support Multicasting, if so ensure it is enabled within your router configuration, as well ensure it have the latest firmware installed..

Mac can no longer find the network NAS

For some reason I can no longer see my NAS when connected to my home network. I go to work and see other computers just fine. It's kind of infuriating.
Any ideas?

Hi Mad Clan
Welcome to the discussions.
You provide very litte information, which leaves us guessing. Please try to be as elaborate as possible in your answers.
First of all: Check the power of the device. You won't believe in how many cases this was the simple solution for my own issues.
Second: Assuming, the NAS is not connected wirelessly: Check the network cables. To be absolutely sure, replace the one connecting the NAS to your network.
What does your home network look like? Do you have a router seperate from your internet connection (meaning you're having two boxes)? Do you connect wirelessly?
What NAS product do you use? Please provide brand and modelname. Did you just take it out of the box and it just worked or did you have to configure network settings?
Can you think of a reason you don't longer see the NAS? Was there a power outage, did you add a new device to the network (if only temporarily, please mention it), had you someone accessing your network who doesn't live in your house, did you update your computer or the router?
All these questions potentially lead to different steps needed to be taken.
Kind regards

Printer can't connect to the network HP photosmart c309a

I keep having connection issues with my printer. I recently moved it from one room to another and it will not connect to the network. When I do the network test, it doesn't find it and it doesn't find an IP address either. Getting very frustrated.....

Try to move the printer back into the previous room and re-connect.
If it connects with no problem, your issue would be the distance between the router and the printer.
It should be presented in the same room. Before you try doing this, unplug your router for about 20 seconds and plug it back in, and try to connect.
Let me know if this helps, thanks.

Laserjet p1102w can't connect to the network

I am trying to connect my laserjet p1102w printer to the wireless network, numerous times, and it still won't work! I have chatted with hp for three times already, uninstalled and installed software, and looked at the manual from cover to cover. Can anyone please help me connect my computer to the network, anything I have tried does not work.

Well now we know what the issue is. You are not connection to your wireless router via SSID and password.
Go here.
http://h10025.www1.hp.com/ewfrf/wc/manualCategory?product=4110396&cc=us&dlc=en&lc=en
and download the Getting Started and User guide. Page 7 of the User guide is where you want to start. You may have already done all this... but you have not detailed anything yet so I don't know. Keep the USB cable disconnected and start the CD. It should prompt you to plug in the USB cable. If not, plug the USB cable in and start the CD again. Now detail each step and let us know where it fails at please.

Does sim-free iphone lock to the network?

HI all,
I've been asking different question here recently connected to iphones and now I have one more question. Does sim-free iphone lock to the carrier of the first sim used in it? I've been using mine for a while and now i'd like to change mobile carrier. So, aren't there going to be any problems with it? Thanks in advance.

Apple does not use the term "SIM free" in any of their marketing materials. If you bought the phone at Carphone Warehouse in the UK, it will lock to the first UK carrier used to activate it. It can not be activated on a foreign network unless unlocked by the UK carrier used to activate it. Other than that, so far as I'm aware, phones are "locked" or "unlocked". I don't know of anywhere else where things are done like they are at carphone warehouse in the UK.
