Native vlan mismatch error msg from cdp
get this message from my 6509 connects to 3550. but no trunking is set between them. my other ports also have the same settings, with no err msg but have a native vlan unknown status... why???
this 6509 is not set by me.. :(
I do not have enough information from you to say if it is a bug. Past output of

How one Switch identify the Native vlan mismatch
Dear All,
I am using two cisco L2 switches. Both are connected by a trunk link. Unfortunately I configured different native vlan between two switches. Suddenly I got an error that native vlan mismatch. When I changed the configuration Now it's working fine. My question is that how one switch identify that native vlan mismatch(either by Bpdu, cdp or packet). Please mention which of the following used by switch to identify native Vlan mismatch.
Regards,
SanjibSanjib, Karsten,
It's CDP.
Yes, and STP as well if you run a trunk between the two switches. PVST+ and RPVST+ BPDUs have a TLV in their trailer that carries the VLAN number for which the BPDU was originated. If the BPDU is received in a different VLAN (caused by a native VLAN mismatch), the receiving switch will be able to detect it.
Wireshark 1.12.x will be capable of displaying this TLV field in captured PVST+ and RPVST+ BPDUs. Until 1.12.x is released, you may want to try daily builds from:
http://www.wireshark.org/download/automated/
They already incorporate the enhancement.

I am getting the following message in my logs on SF300-8
"%CDP-W-NATIVE_VLAN_MISMATCH: Native VLAN mismatch detected on interface fa1."
What is causing the error, see VLAN setup below:Hi,
Yes, in this case you can change the native vlan on the that switch with the command (config-if)#switchport trunk native vlan #, there is no need to reboot the switch in order for the change to take effect.

Hell everyone,
I have a sonicwall firewall with 6 vlan and 3 cisco sg28 switches connected to it, everything is working fine, but I se I have these waring the the log files of all three switches.
I just need to know the best way to resolve this..
the firsrt switch is the "core" switch and the other two are connect to it in a star pattern.
Sonicwall--switch1.101.1----switch 101.10
|
|
switch 101.20
So core switch 101.1 has default vlan set to 100 which is the default lan on the sonicwall that it is connected to. There are no devices in .100
switch 101.10 has devault vlan set to 1
switch 101.20 has default vlan set to 1
switch 101.1 is seeing these warnings..

All,
I have investigated and made sure the speed/duplex have been changed between both devices attached to int-faces.
here is my error.
02-ext-liv FastEthernet0/20 (40).
Feb 20 16:22:18.711 PST: %CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on FastEthernet0/xx
2900 series switch.
What other approach shall I take to pin point the issue since this is only informational on the error log.

Thanks in advance!Hi,
The 'error' message is simply because you have used different VLAN IDs on the access ports at either end. CDP discovers this and logs a warning. The message is pretty harmless in itself.
There are a couple of options to get rid of it:
- configure the access port to be the same VLAN on the two switches at either end of the link
--- OR ----
- enable CDP version 1 on your switches. YOu can do this using: 'no cdp advertise-v2'.
The latter option is simpler and you don't really lose much...
Hope that helps - pls rate the post if it does.

Native Vlan Mismatch on Switch LD connected to
I am running 3 switches each with the same 3 vlans. I also have 2 local directors in failover mode. The primary has interfaces connected to switch one and the secondary has interfaces to switch two. Trunking is disabled on all device ports but enabled on a dedicated fiber connection between the 2 switches
The first vlan is vlan 1 for management
The second is vlan 2 for the gateway side of the local directors
The third is vlan 3 for the server side of the local directors
On the primary switch I am logging CDP messages telling me i have a native vlan mismatch on the 2 local director ports. The secondary switch I dont get these messages.
Any ideas what is going on here and why? Thanks, Art.You mention above " but trunking is enabled on a dedicated fiber connection between the two switches", therefore trunking is enabled.
Because trunked ports need to be assigned to the same native vlan, I would do a "show trunk" and verify that the port used for trunking on each switch, are assigned to the same native vlan, I've seen the mismatch if the are not. That command above is if your switch is using CatalystOS, otherwise, use this command for NativeOS - sh int fast 0/1 switchport and look for the "trunking native mode vlan" number. They must match on each side. To correct the problem, do set vlan 1 4/10 to assign port 4/10 to vlan 1 which, is your management vlan which I assume you've choosen to be your native vlan.
Hope this helps. -

Can anyone tell me or point me in the proper direction for the method to set the native vlan on the WLC? I have a 3750 that is showing a native vlan mismatch going to the 4402.
hello - have a look at this link

Parking error msgs from Inbound queue
Hi Experts,
There are situations when an inbound queue (SMQ2) gets build up because of an error msg. In this case, we manually cancel the error msg and allow subsequent msgs to get process. Is there any way using which we can park the error msg aside automatically (into some new queue, like an error queue) and allow subsequent msgs to get process. This will prevent queues from building up and we can fix all the error msgs at later point of time by checking them from newly created error queue.
Thanks,
AdityaHi,
PI 7.3 has the feature of parking the error queues aside and allows the other messages of queue to process....
I heard this feature is downported to the PI 7.1 also...but no hands on or more info at hand on this...if your are using 7.1 check the sap site...
Apart from that try to check for activation of CCMS alerts so that person is notified in case if message in queue gets blocked..

How to get Error Msg from A step in TestStand into a variable (with Record Result disable)
I have disable "Record Result" in a step (action) that call a Labview VI (Minimise memory usage during long run).
But I want to capture the error msg and put it in a local variable (locals.log).
So in the "Post Expression" of that step, I add:
locals.log = step.result.error.msg
But it always an empty string, Is the post expression executed when the there is an error in the step ?
So How can I capture it ?Hi,
The trouble is that when a step errors, the Post Expression doesn't get executed.
Try using one of the Override callbacks - SequenceFilePostStepRuntimeError, ProcessModelPostStepRuntimeError or StationPostStepRuntimeError.
There is an example in the Examples\Callbacks.
The Step properties are passed as a parameter to the callback so you can get the error message and do your logging.
Hope this helps

I have a requirement of giving error msg and making that row or the particular field input editable by writing code in table event 01 i.e before saving any record in a z-table i have to chk some condition for a column value and if that condition fails then i have to give error msg and make that column input editable.
I have created a routine for event 01 and written the code to give error msg. But my problem is that column is not becoming input editable. Could you pls tell me how can i make that field editable?
Thanks in advance.Hi Piyali,

I am new to peoplesoft adapter, I guess I must miss something important. I am wondering if there is configuration stuff on peoplesoft side? or I should config peopleSoft user from for provisioning instead of standard one?
Any advice is highly appreciated.
Thanks in advanceJason
Thanks for the advice, I really appreciate it.
At IDM side, we have the right psjoa.jar in IDM lib directory, and have the "PeopleSoftCompIntfcAdapter" installed. We also use the default user_profile and delete_user_profile component interfaces.
Per your advice, at peoplesoft side, we need to create the above user_profile and delete_user_profile component interfaces, define the profile data view and audit table for peoplesoft internal actively sync, correct?
As I understood, other 2 different PeopleSoft adapters "PeoplesoftComponentActiveSyncAdapter" and "PeoplesoftComponentResourceAdapter" are totally different from "PeopleSoftComponentIntfcAdapter". In our case, we don't need to follow the instruction to get a copy IDM_peopleSoft project jar file from Sun IDM supporter and import the projects at peopleSoft side, correct?
Sincerely
jxxe
To use the PeopleSoft Component Interface adapter you
need a JAR file from PeopleSoft (psjoa.jar I think).
This JAR is built to the specific version level of
the PeopleSoft environment you have installed.
You also need a Component Interface listener set up
on the PeopleSoft App Server. There is a fair amount
of work involved with this, because you'll also need
a view of PeopleSoft data created (limited to what
you specifically need) and an audit table that will
notify the Active Sync process when there are changes
that require action.

Array size mismatch error (1047) from matlab to labview
Hello all,
I have a very strange situation here and I am hoping someone can come up with some ideas for me...
I am running labview vi's through a web page, and one of my vi's contains a matlab script with two array inputs, one 2d with a varying length, and the second a 1d array with a fixed set of parameters.
If I call this report on my local system, web server labview and matlab all running on my laptop. Everything works fine. I receive no errors and the matlab script runs and returns data as expected.
The problem is I have an Identical setup (as near as I can tell) setup on a server, and I receive a 1047 error, reporting an array size mismatch.
All the input arrays data sets are identical in the vi at the input into the matlab script. And as best as I can tell all sub VI's and M files are identical. The only difference I can come up with is that one setup is running on a server and the other is not, however other vi's using matlab script (although a simpler configuration (no direct inputs or outputs form matlab, all data transferred in and out via txt files )) run fine in both configurations.
On both systems I running matlab ver 7 (R14) with a single user license and Labview 7.1.
any ideas or suggestions would be greatly appreciated. Please let me know if any additional details are needed.
Thank you in advance,
ChrisHello Matt,
Yes you were correct upgraded LV to 7.1.1 and everything is running fine now.
thanks

Ipod Nano 7th Generation - Not Charging / Error Msg From Comp 'Attached Device Malfunctioned'
My IPod Nano 7th gen arrived last night. I was able to turn it on and select language 'english' When I connected it to my computer it did not recognize my iPod, so it also did not show up in iTunes, Error message: "One of the USB devices attached to this computer has malfunctioned. and Windows does not recognize it."
My Nano turned off and went blank. I have tried to reset it. Nothing works, just blank.
No charge icon, I have tried all USB ports on my comp, but nothing works- (but my USB ports work fine) I have read that if my iPod has not been charged fully, the computer my not recognize it.
I am now using an adapter and trying to charge it thru the wall power socket. It has been connected for half an hour. Still cannot turn iPod on.
I have Windows 7 running on comp. Itunes is current version 10.7. I have rebooted my comp several times and re-installed iTunes.
I have an iPhone and an iPod shuffle that are both synced with iTunes on this comp, they work fine.
Is my iPod broken? Do I send it back? Anyone else having the same problems? Please Help !!I had this problem as well. I have a PC running Windows 7. I have installed the latest iTunes 10.7 software (64 bit). I reset the nano by holding down the start and home button for 10 seconds. Then - I plugged it into a PC running Windows XP and was able to format the iPod. Ejected it and plugged it into my Windows 7 computer and then the computer recognized it and I was able to load it. There is some problem with iTunes 7 on Windows 7.

Hello! I have a network in with a i have a switch stack configured for voice and data. Particularly, both are configured to pass over the same port.
I want to add a temporary switch (different model) to the network and configure it the same way. In particular, I want to see that I can set up the voice/data VLAN's on this new switch and test to confirm all is working. I need an uplink though back to the original switches so that this new switch can get a proper connection.
When I connect the new switch in, I can't seem to get an IP and the CLI keeps showing a "Native VLAN mismatch error" and shows the hostname of the original switch.
So my questions are:
How can I add this temporary switch to the existing switch to get a connection, not as another stacked switch?
How can I configure the voice/data VLAN's on the switch so as to be able to test the voice/data traffic over the same port?Hi! Yes I did change the native vlan for that particular port on "Sw2" (New switch) to match "Sw1" (existing switch). The Sw2 port shows native vlan inactive though.
