VTP Domain Name and Transparent Mode

Can two switches connect via a trunk, one as a server and one as transparent and be in two different VTP domains respectively?

Hi Guys,
For the error messgae below:
Error Message DTP-5-DOMAINMISMATCH: Unable to perform trunk negotiation on port
[chars] because of VTP domain mismatch.
This you will got only when you have an automatic trunk negotiation using the DTP (dynamic trunking protocol) between the switches. The switches with different VTP domain name will not negotiate a trunk and a trunk will not form. But if you configure a trunk manually (not using DTP) then the trunk will work.
HTH, Please rate if this helps

VTP domain name change

we have a number of campus LANs that for historical reasons, all have the same VTP domain name (even though they are seperate domains).
we'd like to change the domain names so that they are unique throughout the network. is the correct method of acheiving this:-
1 change VTP server to Transparent Mode
2 change VTP domain on 'server' to new domain
3 change all Client switches on campus to Transparent mode and change domain name to new one. change mode back to Client and then restart.
any advice appreciated
thanks
andy

Hi Andy,
I believe you have 2 VTP servers in your network with different VTP domain names and both VTP servers are playing role seperately for their VTP domains? Correct me if I am wrong?
If I am right you can go ahead with your plan and change your one VTP server which you waan sync with your other VTP server to transparent mode and then chage the VTP domain name then change it back to server mode so that you can also have 2 VTP servers in same VTP domain for any emmergency.
Talking about clients you can follow the same procedure as changing from client to transparent, then change the domain name and then back to client and you need not reload your switches.
Also remember while doing all these when you move your one VTP server and clients to different VTP domain name the VLAN information will get override by VLAN information persisting on your other VTP server and if this is what you want just go ahead.
Devang I did not undersood your BPDU stuff in this context can you please throw more light on the same.

4503 VTP Domain Name

I have a lab that consists of 2 - 4503 with SUPII running cat4000-i9s-mz.122-25.EWA14.bin as the core devices. I have been practicing for the BCMSN test and was working with the different VTP confiuration options. Here are the two issues that I am having. One of which from reading other posts, I may have answered, but want to verify.
1- 4503 (Core_1) was configured as Server, but no VTP summary advertisements where being propegated to the other clients. I verified the configuration multiple times to ensure accuracy. All VTP Domain names where empty (factory default). Not until I changed the VTP Domain name to Test, did I get propegation of vtp advertisements. I have in the past been able to set up vtp on 3550, 3560 switches with no VTP Domain name and VTP worked as expected. From reading, it appears the non propegation of vtp summary advertisements is the norm for 4503. Can someone verity this.
2- How do you remove the VTP Domain name from the 4503? I was able to remove the name from the other devices, 3550, 3560 by doing the following:
     del flash:vlan.dat
      wr er
      reload
     On the 4503 I did the following:
      Switch#del /r /f cat4000_flash:vlan.dat
      reload
     After reload, everything was back. I also assumed when the 4503 was booting, it may have recieved the VTP information from the other 4503. So I isolated both by disconnecting the uplinks to all other devices. Still no go. I have copied the start-up config to a tftp server, modified the config by removing all vtp information then copied back to running-config and this worked. But it seems like there should be a better (easier) way of getting the vtp domain name removed on a 4503

Hi,
Deleting the vlan.dat from cisco switches will delete the complete vlan and vtp information from database and if you are not able to delete the domain name in these type of situation try configuring the some bogus name with mode as transperent mode so that other should not get impacted.
check out the below link for more information

The difference between VTP server and transparent mode on Catalyst Switch.

Hello
I have a question about the difference between VTP server mode and VTP transparent mode on general catalyst switch.
Basically VTP server mode can create and modify VLAN configuration but actually there is not any VLAN configuration through running-config, is it true? When I checked it on Cat3550, certainly there is not VLAN configuration on VTP server mode. But VTP transparent can create VLAN and configuration but does not synchronize with other switch VLAN status. I appreciate any related information and reason of the VTP server mode specification, thank you very much.

The above out put indicates that Vlan is created and then mode changed to transparent. i.e why revision no is 0.

This indicates that vlan never created in server mode nor learnt from another switch as revision no is 0

In a vtp domain how many server mode switches can be

dear sir,
in a vtp domain how many server mode switches should be.
what role transpranent mode vtp domain and were we are using it.

Hi Mukhtar,
You can have all the switches in server mode in your network but it is always recommended to have atleast 1 and better to have 2 in your network.
One is required because VTP server is the only switch from where you can modify, add or delete vlan and it will be propogated to all client switch but 2 is recommended to have redundancy incase your one VTP server goes down you will be having another ot take care of your network.
Talking about VTP mode transparent, this mode will allow you to create,delete and modify any vlans but will not participate in any VTP messages and it will also not propogate its VLAN information to anyone in the network.
Also if you want to go for extended range of vlan which is above 1005 you have to configure your siwtch in VTP transparent mode only.
To know more about VTP have a look at this link

The publishing settings page does not open when I click on the domain name and the iWeb application will not stay on the dock.

Hello,
I have been trying to help a friend who is having problems publishing her website. (She has done so previously using Mobile me)
There seem to be a couple of things wrong with the application,
1 if I drag the application icon onto the dock, it won't stay there
2 I wanted to change where her site is published to (she has bought a domain name and has a hosting service now) but when I click on the domain name I do not get the "site publishing settings page" so we can't enter the new details. All that comes up is the main page of her website.
I would suggest uninstalling and re-installing Iweb, to see if that clears the problem, but as Iweb came pre-installed with her Imac, I am not sure that we can do this.
Any ideas please?
she's using and imac 24 in (approx 4 years old) and running osx 10.5.8

NO - not correct. Even if you are still using iWeb 08, you can still publish to another host and not MobileMe. You do this by selecting the option 'Publish to a local folder" and this will publish the site to your desktop and you can then use an ftp programme such as Cyberduck to upload your site to your host.
MobileMe will not be here after the end of June, so you will have to find alternative hosting. They are not taking any new subscriptions.
On new Macs, iLife 11 is pre-installed, but only iPhoto, iMovie and GarageBand are included, not iWeb and iDVD. The Apple Online store is not selling the boxed version of iLife 11 any longer, so if you want to upgrade to iLife, then you'll have to look online at Amazon.com or Amazon.co.uk for a boxed set of either iLife 09 or iLife 11. Both contains iWeb 09, which is what you would want.

Domain name and session

Hi ,
We have deployed our application on tomcat server built on struts framework.
We have also set the domain name and are redirecting the domain name to Static Ip
where our application is deployed with URL Masking option enabled.
Everything is working fine in Firefox.But in IE6 and IE7 we are facing issues related to sessions.
Example:
it works when we access directly
http://156.78.78.89:8000/myapp/login.do?method=display
     when i redirect this with a domain name(with URL masking enabled) like
     http://www.mydomain.com It does not work.
     I am not able to login into application(using sessions of this) or use shopping cart(using cookies)
Cookies are getting disabled and there is no session maintainance.
Is it problem with struts config or tomcat server?
I am unable to take my application live because of this issue.
Please help me to solve. Thank you for your time and consideration

Problem with external domain name and hosting

Hi I have my own domain name and hosting plan I want to use. However, I have trouble pointing my site from BC to my server.
I found the following information but in my case "create A-Records" is not available on the "Site Domains". Please advise.
Thanks.

Point externally hosted domains to your Business Catalyst site
If you have chosen to use external DNS service for your domain name, create A-Records for both the www and non-www versions of your domain name. Then, point them to your site, which resides on one of the following IP addresses:

Hi
Can you please confirm that there is no “Create A records” option under “More Actions” ?

Domain name and iweb - masking url?

Just go to the whatever place has your domain name and ask them or search in their FAQ or Help for how to do Domain Forwarding and Masking.

Will vmware horizon work after change domain name and ip adress and vcenter ?

Horizon View is depended on AD and this task is not trivial.
What needs to be done depends on your setup and configuration and you will need assist from VMware Support and you should first replicate the setup in a test-environment.

Get Windows domain name and user through jsp

I have a jsp page that will be viewed through ie on windows platform, that is a member of domain.
I need to get the domain name and logged in windows user name to use it in my page.
I've looked through similar topics. Found no answer.
1.
System.parameter("user.name") is not ok. it returns user that runs jvm.
2.
import com.sun.security.auth.module.NTSystem;
NTSystem system = new NTSystem();
system.getDomain()
system.getName()that didn't work through jsp, though the answer is correct.
3. I found some api at http://www.sinotar.com/download/swin/doc/index.html
it did the right thing, but it's not free.
Could anyone advice me smth?
I've looked

well, it won't work in your jsp because jsps run server-side
could try putting an applet on your page that does it, but I wouldn't be surprised if the security manager put the kibosh on that, too
a third - but clunky - way would be to write a quick java app that does it, and launch it through WebStart. bit ugly, and needs extra user input they might not want to do

Domain name and search engines

Hi
There have been a few helpful postings about the importance
of having text on your frontpage for crawlers etc to improve your
search ranking. My question: how important is the domain name for
search engines? Is it worth investing a dime or 2 on a good generic
domain? If you needed to have 2 words (e.g. www.top-lawyer.com) is
it better to have them combined (e.g. www.toplawyer.com).
PS This is just an example...I am not a lawyer!

I think that your both confusing "domain names" and
"domain/web space
hosting" here.
Typically you register with a hosting company and receive an
amount of disk
space. bandwith etc and a domain name, say
www.thru-the-net.com
You create your web site and upload it to the serve and
people can access
your web site at www.thru-the-net.com
Now you realise that many people outside the US are entering
www.through-the-net.com so you get your provider to register
www.through-the-net.com for you as well and they POINT this
address to
www.thru-the-net.com. That is to say when people enter
www.through-net.com
the actually end up at www.thru-the net.com i.e. the same
place.
This is o.k. you can have as many variations as you want -
www.thru-the-net.com
www.through-the-net.com
www.thruthenet.com
www.throughthenet.com
www.thru-the-net.net
www.through-the-net.net
etc. all pointing to the same www.thru-the-net.com server.
This is o.k. and
the search engines don't mind this.
BUT
If you have SEPARATE web space for each of these domain name
variants and
just copy your entire site into each of these spaces, now the
domains are
not being forwarded. They are entirely stand alone domains
that are all the
same.
Search engines DON'T like these and see them as an attempt at
improving
ranking and therefore penalise all of them.
Sorry for being so long winded, but hopefully this makes
sense.
