Nexus 9396PX support only with VTP transparent mode
Why Nexus 9396PX not support vtp server and client mode ?
We are using with 6.1(2)I3(2) version.
Thanks.
Is any expert out there who can answer my query ?. Much appreciated.

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

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
maheshMahesh,
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.

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

I have 2 cisco c2950 switches, I have 2 problems:
1- I can't create more than 1001 vlan..(I have configured the both switches with vtp transparent mode).
2- when I issue the command (sh vtp status), I noticed that vlans supported locally 64 & number of existing vlans are 63.
(a)does that means Spantree won't operate after vlan number 64. If so? how would I solve this issue?
(b) what is the possiblity that allows me to assign more than 1001 (Extended vlans) in cisco c2950 series?Hi Friend,
Catalyst 2950 switches that run the standard software image (SI) support 64 VLANs; Catalyst 2950 and Catalyst 2955 switches that run the enhanced software image (EI) support 250 VLANs. Refer to the release notes for the list of switches that support each image. VLANs are identified with a number from 1 to 4094 when the EI is installed and 1 to 1005 when the SI is installed. VLAN IDs 1002 through 1005 are reserved for Token Ring and FDDI VLANs. VTP only learns normal-range VLANs, with VLAN IDs 1 to 1005; VLAN IDs greater than 1005 are extended-range VLANs and are not stored in the VLAN database. The switch must be in VTP transparent mode when you create VLAN IDs from 1006 to 4094.

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.

This indicates that vlan never created in server mode nor learnt from another switch as revision no is 0 -
Hi Guys,
I had to re-post this here because I did not get any comments earlier.. hopefully I'll get something here.. :)
I'm investigating the ways that I can use 2 x ASA (5525x) to accommodate Multi-tenancy situation with overlapping addresses. Unfortunately in this particular scenario we have to stick with 5525x firewalls.
The ASAs are going to be placed in north-south traffic path between 2 routers and these routers need to be configured with multiple VRFs to segregate the traffic for each tenant with overlapping IP subnets ( We are not looking at NAT as a workaround for the time being).
As we know, this ASA model won't support VRFs so we can't use the ASA as a intermediary routing hop and therefore this is not an option.. and using security contexts per VRF seems not scale-able enough (correct me if I'm wrong). So my thinking is that, if we put the ASAs in to the transparent mode and just use the ASAs as a layer 2 interconnect (configured with different VLANs connecting VRFs served by top and bottom routers) I should be able to go up to maximum of 50 VRFs (since 5525x only supports 200 VLANs).
I'm also planning to use the 2 ASAs in a cluster mode to aggregate the bandwidth of both ASAs for better throughput.
So I need to clarify following with you guys..
1) Can I actually do this or am I missing something.
2) Are there any limitations that I might run in to with this setup
3) Is there anyone out there who's doing the same thing or can you think of a better way to tackle this scenario (with same hardware and requirements)
4) Instead of using clustering, can I use simple Active/Stanby pare and still configure transparent mode and use it that way ?
Appreciate your input.
Thanks
ShamalThere is a limitation on how many context you can have, which depends on the license you have. This is quite possible with ASA multi routed mode and even with multi transparent mode. You can have overlapping ip in each context without the need of using nat as long as you have unique mac address for each sub interface.

Connectivity Issues Cisco ASA 5515 in Transparent Mode
Hi,
we´re having problems with one transparent mode setup at one customer site. The ASA is equiped with a CX Module, but we´re not using it, so far in the service policy rules it was enabled and matched all traffic, but in "monitor only" mode. There is a global acl that allows any-any-IP.
Firewall-Info:
- ASA Version 9.1(2)
- Interfaces gi0/0 + gi0/2 without any interface errors
The ASA 5515x is configured as a "bump in the wire". In general our setup is working but with beginning of the installation of the firewall the customer faces following connection issues, without the firewall no problems:
- Connections to SAP-Servers behind the MPLS begin to drop, affected all users
- Incoming monitoring sessions (ping/snmp) from central management are facing ping timeouts, connection timeouts
- http downloads are stopping, Customer: it will stop responding and the download will fail.
In general the customer describes it this way: "We do not have the best connection here so once we connected the firewall all the problems are magnified"
I recognized, that we unconfigured the default inspection during initial setup and reconfigured this entry for the cx module. So the the default inspection with all the settings are not present any more... How important are these settings? One phenomen is, that I´ve seen a large numbers of concurrent connections that increased over time. And we already had that situation, that the firewall reached the max-conn count.
Should I try to reconfigure the default inspection, as it ships from factory? And whats the best way to check for problems? What can be the reason for the dropping connections?
I attached a network plan and the firewall config, hopefully, that somebody has an idea. Of course I can provide additional information...
Best Regards
SebastianHi Vibhor,
thanks for your reply. Does this also affect the traffic, even the setting is set to "Monitor Only" ?
Is it recommend to configure the default-inspection rule as a default setting?
Further Question: I´ve read sth. about, that service policy rules must be "reloaded" to take effect, after they have been changed. Is that right and how do I reload them?
Here is an output from sh asp drop, do I have to care about certain values? This values result from two connected users doing some downloads over a 2Mbit connection.

Why my VTP client switch changes automatically to vtp transparent?
hi ppl!
i got a severe problem in my network. currently, we are implementing cisco 5509 catos based layer switch as our vtp mode server. so when i tried to hook up a new cisco 2950 switch by configuring it as vtp client with the same vtp domain name with dat of cisco 5509 vtp server mode, it will automatically change to vtp transparent mode but with the same vtp domain name. so, is there anyone dat can give me the best solution to mitigate my problem. e-mail me via [email protected]

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.Disclaimer

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. -
Using Clustered ASAs in Transparent mode to support VRF based Network ?

Failure when FWSM in transparent mode with multiple contexts
hi experts,
We have two FWSMs working in active/standby state, configured with multiple contexts in transparent mode. and the "outside" and "inside" interfaces for each context are in same subnet.
Now we have one FWSM broken and the RMA part can't arrived in short time, so we have the risk that the sencond FWSM could be failed as well. In the worst case if the two was broken or powered off simultaneously, i wonder that if the communications between multiple contexts could be ok???
thanks in advance.The software requirements for Cisco Secure ACS are dependent on the type of Extensible Authentication Protocol (EAP) desired. For full support of all the EAP types including EAP-Flexible Authentication via Secure Tunneling (FAST), use release 3.2.3 or higher.

VTP v2 Transparent mode forwarding
All,
As part of my recertification, i am studying VTP (again) and i ran into the following question:
I know VTP v1 switches in transparent mode only forward VTP advertisements if the domain name is the same and if the version is the same (so only v1 gets forwarded and only if the domain name matches)
I know VTP v2 has a feature called: version-independent forwarding: a VTP v2 transparent switch will forward VTP v2 packets as well as VTP v1 packets.
BUT what about the domain name ? Does it still need to match ?
Will a VTP v2 Transparent Switch in domain "Cisco" forward a VTP v1 or v2 advertisement of domain "TEST" ???
regards,
GeertOk. Thx. Let us believe the documentation.
Although it is not really clear why this feature is called "version dependent transparent mode" and not "version independent transparent mode". To me it seems more logical - since it forwards v1 and v2 - to be version independent...
So in the following situation:
SW1 ---- trunk --- SW2 ----- trunk----- SW3
Server Transparent Client
VLANS 1,2,3
Domain TEST Domain Cisco Domain TEST
If SW2 is running VTP v1 --> SW3 does not know any VLANs
If SW2 is running VTP v2 --> SW3 does see VLANS 1,2,3
