VTP change from server mode to transparent mode

Hi,
We have a VTP domain in which all switches are in transparent mode. However, several have the wrong domain name or mode. As a result, some errors are being displayed in the log. I would like to change the VTP configuration in those switches. They are all in a production network. Which would be the best way to do it without causing problems to the network?
Regarding the switches which are in mode server and have a wrong domain name, should I change firstly the mode to transparent and then the domain name? Is there any risk of losing the vlan configuration?
Thanks in advance.

You write, all switches are in transparent mode, but also regarding those in server mode - i.e. which is it?
"Safest" would be to switch a server (or client) mode switch to transparent before changing domain name. If you switch domain name first, yes you expose having shared VLAN information changed.

Cannot change from server core 2012 to gui

I have tried EVERYTHING (and I mean everything), but I cannot update from a server core 2012 to gui. I get the source error everytime. I have manually downloaded patches, and updated the source, but did not work. The server is connected to the internet.
Really wishing I could just switch to RedHat for this server, but unfortunately the acronis management server doesn't run on redhat (at least with redhat you pay for support, not just the privilege to use their shitty software, so when you have problems you
can contact them). Every article or blogs says the samething, but it does not work.

And the first thing to check for is to ensure that you installed Windows Server 2012 and not Hyper-V Server 2012. Windows Server you can update. Hyper-V Server you cannot.

VTP Transparent Mode in 2924XL/3524XL

I have a 2924XL ver12.0(5)WC11 connected to two 3550 ver12.1(22)EA5 via 802.1Q trunks. They are all in the same VTP domain. The 2924XL is in VTP Client mode & the two 3550s are in VTP Server mode. There are only 6 vlans - 1, 223, 1002, 1003, 1004, & 1005. I am attempting to change all switches to VTP Transparent mode.
Starting w/the 2924XL, when I change mode from VPT Client mode to VTP Transparent mode, the interfaces w/the trunk links immediately bounce & when they come back up, communication is only established thru VLAN1 & am no longer to communicate to devices in VLAN223.
Connection was restored when I reconfigured the 2924XL back to VTP Client mode.
What is causing this problem & what is the proper way to convert to Transparent mode w/o interruption of service?
Thanks!

Humm ...
well, please help me to understand the problem.
The VTP Client saves the vlan infos in RAM, and not in NVRAM like VTP Server ... when you change the VTP mode Client to Transparent, why you lose you vlan infos?
If you do a "sh vlan" on one of your switches that is in client mode, then change it to be in transparent mode, none of them would disappear.
It will simply stop listening to vtp messages regarding the creation and deletion of vlans.
Then, of course, you have to create the vlan database in NVRAM ...
Thanks for your support

Authorware 7 Transparent mode

Can anyone tell me how to set Transparent mode for all
imported display icons by default. I am currently going through
thousands of imported icons that all need to be switch to
transparent mode.

Transparent mode does not belong to the icon, but to the
objects in it.
However, if you select the icons you want to change after all
the graphics
are imported and go to Edit>Change properties, you can
accomplish what you
want.

ASA 5510 in Transparent Mode-Guidelines.

Dear all,
I need to convert routed mode to transparent mode on my ASA-5510 with inbuilt IPS.
let me know which of the following features configured on my firewall will have issue if converted to transparent mode:
1. static routes.
2. object-groups.
3. ACLS.
4. URL-filter (Websense).
5. IPS . ( i doubt this )
6. have 3 data and 1 Mgmt interfaces.
7. syslog.
8. SNMP
I'm sure point 5 and 6 will have issues, need to confirm.
need to confirm this by EOD,
( 5 hours more).
thanks in advance.
Shukla.

Does not participate in routing protocols but can still pass routing protocol traffic through it. You can define static routes for the traffic originated by the ASA.
in transparante mode the devices dehind and infront of the firewall will be in the same ip subnet as the firewall will be a L2 device!!
ACLs can be configured normally
syslog as well
obgect groups as well
Address translation is inherent when a firewall is configured for routed mode. Beginning with
ASA 8.0, address translation can be used in transparent mode as well
Does not participate in multicast. However, it allows passing the multicast traffic through it using the ACLs.
Does not support QoS.
Inspects Layer 2 and higher packet headers
as long as u can use
policy-map global_policy
then u can integrate with IPS if u mean AIP-ssm modul
transparent also known as a Layer 2 firewall or a stealth firewall, because its
interfaces have no IP addresses and cannot be detected or manipulated. Only a single
management address can be configured on the firewall
In transparent mode, a firewall can support only two interfaces-the inside and the outside. If
your firewall supports more than two interfaces from a physical and licensing standpoint, you
can assign the inside and outside to two interfaces arbitrarily. As soon as those interfaces are
configured, the firewall does not permit a third interface to be configured.
Some platforms also support a dedicated management interface, which can be used for all
firewall management traffic. However, the management interface cannot be involved in
accepting or inspecting user traffic
Configure a management address:
Firewall(config)# ip address ip_address subnet_mask
The firewall can support only a single IP address for management purposes. The address is
not bound to an interface, as in routed mode. Rather, it is assigned to the firewall itself,
accessible from either of the bridged interfaces.
The management address is used for all types of firewall management traffic, such as Telnet,
SSH, HTTP, SNMP, Syslog, TFTP, FTP, and so on.
A transparent firewall can also support multiple security contexts. In that case, interface IP
addresses must be configured from the respective context. The system execution space uses
the admin context interfaces and IP addresses for its management traffic
You do not have to configure a static route for the subnet directly connected to the firewall
interfaces. However, you should define one static route as a default route toward the outside
public network

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.

Hi mhiyoshi,

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

VTP from server to client mode

Hi,
I have couple switches setup in VTP server mode. All of them have the same VTP revision number, but most of them should be in VTP client mode.
Will switching some of them (but the one I really want to have in VTP server mode) into VTP client mode have negative impact on the network? I do know that if you change a switch (with the highest rev #) from client mode to server mode I could end up with problems. However, in my case it will be switching them from server to client mode with all of them with the same Rev #.
Thanks for the help

Hello,
change the switches in question to VTP transparent mode first, and then to client mode, that will reset the revision and prevent any possible conflicts.
In addition, in case you need to change the root switch as well, in general the VTP server switch should also be the root for your VLANs. You can set the switch as root by configuring it as:
spanning-tree vlan x priority 0

Move a switch from VTP client mode to VTP transparent mode

Hi,
Does anybody have an experience / knowledge if I move a switch from VTP client mode to VTP transparent mode, should I re-create all the VLANs on this switch?
Thank you!

Hi there,
The VTP and the VLANs are seperate beasts.
The switch has a vlan database which is held in a seperate file to the config. If you type "sh flash" you'll see it in there.
VTP passes around the VLAN information and the switch stores it in the vlan database. If you remove the switch from the VTP domain, then VTP will not be able to update this file and it will remain exactly as it was.
In short - if you've got 20 vlans, when you go to VTP transparent, you'll still have 20 vlans

What is the advantage of setting VTP mode to transparent?

I have a Cat 6509 and eighteen 3524 and/or 3548's. Obviously I want my 6509 to be in VTP server mode. But is there any advantage/disadvantage to having the 3500's in client or transparent. I would think client, but is transparent use less resources, both internal to the switch, and , external, i.e., network resources. I've seen some CCIE's insist that the 3500's must be in transparent mode and configure the VLAN info on them manually. What is preferred?

Configuring VTP in transparent mode requires manual configuration, a VTP-transparent switch does not advertise VLAN information to other switches and will ignore VTP updates from VTP clients and servers.
VTP propagates information about the VLAN configuration throughout the switched network. A Catalyst 6000 family switch can operate in any one of these three VTP modes:
Server—VTP servers advertise their VLAN configuration to other switches in the same VTP domain and synchronize their VLAN configuration with other switches based on advertisements received over trunk links. VTP server is the default mode.
Client—VTP clients are similar to VTP servers, except that you cannot create, change, or delete VLANs on a VTP client.
Transparent—VTP transparent switches do not participate in VTP. A VTP transparent switch does not advertise its VLAN configuration and does not synchronize its VLAN configuration based on received advertisements.

VTP transparent mode and using VTP domain

                   Hi all,
Need to ask question when using VTP transparent mode is it good idea to use VTP domain name and password?
I know for switches in transparent mode they act as independent of each other.
So need to know why we should use vtp domain and password with transparent mode?
thanks
mahesh

Mahesh,
I know this 2 years later, but it will help others who will come across this. If you have a Transparent switch mixed with Server and Clients switches. This is your concern....... If you do not put the Transparent switch in the same domain, then it will not forward VLAN changes to other swithces.
So Sw1(Server-CCIE Domain) <-------> Sw2(Transparent-CCIE Domain)  <-------> Sw3(Client-CCIE Domain)
The above will work because the Transparent switch is in the same domain. This means that SW3 will get any Vlan changes that are done on SW1.
Now lets look at it the other way.........
Sw1(Server-CCIE Domain) <-------> Sw2(Transparent-Null Domain)  <-------> Sw3(Client-CCIE Domain)
Two things are going to happen here
1) The transparent switch is not on same domain, so SW3 will never get any updates when changes to Vlans are done on SW1. So if I add one vlan to SW1, and that make the Configuration Revision increase to the value of 10, that means SW3's Revision will still be 9, and will remain that way until the issue is corrected.
2) If you are dynamically negotiating trunks, this will never happen due to the mismatch domains. Meaning that your trunks will never come up because you did not put your Transparent switch in the same domain.

Update/Insert mode couldn't apply to SQL Server source via Transparent Gateway.

Hi all,
OWB version is 9.0.2.56,database version is 9i Release 2.
When set load type to "Insert",mapping works fine from SQL Server to Oracle table,via Transparent Gateway 901.
But "Update/Insert" always runs error with "Fatal error or maximum number of errors exceeded".while I define both source and destination table to oracle tables in mapping,"Update/Insert" works file.
Any suggestion?

Hi Ignor,
Thanks for your reply!
The SQL Server version is SQL Server 2000.
I just want to ETL data from a SQL Server table via Transparent gateway into oracle table,the source table has a increment seq field,so I want to define mapping using update/insert loading method in OWB,according to this seq field,if there is the same seq in the target table,do update,if not,insert the row.I just find out that if I use a middle table in oracle to do truncate/insert mode from SQL Server source table,then do update/insert mode from the middle one to target table,it works.But can't do directly from source to target using update/insert mode.Does this means update/insert mode only apply to mapping from local table to local table?

Shrink Log file in log shipping and change the database state from Standby to No recovery mode

Hello all,
I have configured sql server 2008 R2 log shipping for some databases and I have two issues:
can I shrink the log file for these databases: If I change the primary database from full to simple and shrink the log file then change it back to full recovery mode the log shipping will fail, I've seen some answers talked about using "No
Truncate" option, but as I know this option will not affect the log file and it will shrink the data file only.
I also can't create maintenance to reconfigure the log shipping every time I want to shrink the log file because the database size is huge and it will take time to restore in the DR site, so the reconfiguration
is not an option :(
how can I change the secondary database state from Standby to No recovery mode? I tried to change it from the wizard and wait until the next restore for the transaction log backup, but the job failed and the error was: "the step failed". I need
to do this to change the mdf and ldf file location for the secondary databases.
can any one help?
Thanks in advance,

1. If you change recovery model of database in logshipping to simple and back to full Logshipping will break and logs wont be resored on Secondary server as log chain will be broken.You can shrink log file of primary database but why would you need that
what is schedule of log backup. Frequent log backup is already taking care of log files why to shrink it and create performance load on system when log file will ultimately grow and since because instant file initilaization is not for Log files it takes time
to grow and thus slows performace.
You said you want to shrink as Database size is huge is it huge or does it have lots of free space. dont worry about data file free space it will eventually be utilized by SQL server when more data comes
2. You are following wrong method changing state to no recovery would not even allow you to run select queries which you can run in Standby mode. Please refer below link to move Secondary data and log files

Configure OEL 6.4 from Server mode to Desktop Mode

I have installed the OEL 6.4 in server mode, and now sucessfully using it. I have installed the Oracle databases on it for testing purpose.
Can you please guide me, if i can configure it in Desktop mode. I do not want to re-install it.
As per my understanding, i need to install some GUI packages for this, but not sure..what is the exact method.
Can you please guide me to configure it from Server mode to Desktop mode(GUI).
Regards,
-DBATurn

You mean how to install the Gnome graphical desktop environment?
Copying the following to the Terminal prompt or console as root should do, and give you a similar desktop like in the previous OL release version:
yum groupinstall "X Window System" Desktop "General Purpose Desktop" \
"Graphical Administration Tools" "Legacy X Window System compatibility" \
system-config-lvm
To test it, type:
init 5
Or to make the change permanent, modify /etc/inittab.
sed -i 's|id:3:initdefault:|id:5:initdefault:|g' /etc/inittab
shutdown -r now
