L2 stack switch - to end-user devices

Hi all,
I came across a design in my project today and realize that there are 3 x L2 stack switches which will be connecting to end-user computers.
According to the client, for end-user devices, he intend to just connect 1device/interface.
Q1) I am wondering, in this design, the only intention is to increase the number of interfaces/ports , am i right ? as there is only 1 physical cable for each connected device.
==========================================================================================
In the same design, there is 2 x L3 switches which are meant for core network connecting to servers computers. They are stacked as well.
In this case, etherchannels are configured on the switches and servers which the 2 interfaces in 1 server are connecting to separate switches' interface in the stack.
Q2) Can I check, for this kind of switch stacking setup, are the etherchannels configure as active, active or it can be configure as active,passive ? or it is switches and servers dependable ?

Hi Reza,
Thanks for the reply.
Q1) I am wondering, in this design, the only intention is to increase the number of interfaces/ports , am i right ? as there is only 1 physical cable for each connected device.
That is correct. The end devices (printers, PCs, laptops) usually have one physical cable and you can only connect them to one switch, but sometimes for mission critical environments engineers deploy multiple switches in case one of them goes out for any reason.
What if in the event that 1 of the switch go down, as the switches are stacked, can i just plug out the cable @ interface let's say at switch1 fe0/1 and insert it into switch2 fe0/1 ? (provided it is not occupied)
Q2) Can I check, for this kind of switch stacking setup, are the etherchannels configure as active, active or it can be configure as active,passive ? or it is switches and servers dependable ?
If you issue "sh etherca summay" on the stack, it will show you the port number that are part of that etherchannel. As for active or passive, usually the switch is configured as active and servers as passive but you can also configure both sides as active.
Do you mean on the server side, only 1 port will be receiving/sending information, but on the switch side, each interface at each of the 2 switches is able to receive/send ?

How to get end user license for BT stack?

How do i get an end user license for BT stack ver 5 ?
Thank you !

Talk with BT device manufacturer. If you use BT device with Toshiba BT software they should help you to get update.

HT201441 If the previous end-user passed away suddenly and did not leave the password word with anyone, how then can the device be wiped?

My company issues iPads to certain staff for their line of work. If the previous end-user passed away suddenly and did not leave their iCloud password word with anyone, how then can the device be wiped. Currently we cannot turn off the iCloud, change the user, update the iOS, nor update our apps. Can the local Apple Store assist in some way?

I think Winston hit the nail. I imagine the issue is you allowed the person to set up personal and private accounts on the device, not corporate controlled accounts. As such, regardless of your ownership of the device, Apple will not release or change personal or private account-related information to you.
Whether they would or not to a direct family member, I do not know, but I highly doubt they will (or legally can) do so to you as the employer for a personal account.
I know such instances have come up in the past with things like company phones and such, both involving Apple as well as other companies. The reported results in news articles were always that private information is private, and if companies want access or control, then they need to restrict employees use to only corporate provided accounts and services.

Dissociate an end user with the primary device

I need to "Enable Mobily" for a new hire and I need to select his phone as the primary device. However, I run into this error: "Update failed. Device is already associated with another End User as Primary device"
Is there a way to dissociate the old end user with the primary device? As a last report solution, do you think that by deleting the phone off the CUCM, it will fix the issue when I add the phone back to CUCM?
Many thanks!
-Calin

Thank you George for your prompt response. :)
How would you "hunt down the other user" in order to make sure the phone is not associated with that particular user. We have about 3000 phones.
I checked the phone settings under "Device" - "Phone" and there is no user under "Owner User ID". Although, I think that this field "Owner User ID" is not connected in any way to Extension Mobility.
Thanks!

Using 37xx stack switch can I send snmp messages as syslog ?

In my environment, we are having cisco 37xx stack switches, I want to know is it possible to use the switch config to send snmp traps as syslog messages to the Syslog-server.
In our case, we are using siem which has the ability to process syslog messages from different networking switches. What specific event I'm after is related to bandwidth utilization of the interface. It would have been great if there was existing syslog-event for exceeded bandwidth or increase in bandwidth beyond certain bps rate. The only place such information can be obtained is from snmp, but the siem station doesn't understand snmp, So I hope there are some setting which allows the conversion of snmp traps to syslog msg to be forwarded to destination.
Thanks.

The iPad cannot use your Android phone number at all so it will not in any way be associated with the device or your Apple ID. You will be using your Apple ID email address as your connect address to use Messages. If you want to look at it this way, your iPad/iMessages will be associated with your Apple account/Apple ID, not with the Android phone number.
Where some users get into problems is if they go from an iPhone number to an Android phone number. That is not what you are doing.

Push Notifications to end users and Conditional Success Screen Name ?

Hi,
Scenario: PO Approval
Description: I am developing a PO approval application with 3 levels of approval. The HWC application is based on the push notification ( DCN with payload ). When a PO ( Purchase Order ) is created/modified the end user will get the notification. Once the first 2 levels of approval is done from the mobile devices the notification should reach the 3rd level for approval. And Conditional Based Users only View there Profiles, If an User1 Approved PO Approval then only User2 Will get Push Notification but for User3 it will not Visible, Oncethe User2 Approved then Only User3 will get Push Notifications and these 3 Profiles have to be log in Based on Condition Name & Conditional Success Screen Name.
Question: How to set to which user the notification should reach. In the "to" field of JSON when I am providing "supAdmin" means the notification will reach all the devices who has the application. Once a PO is created the notification should reach only to user in the first level. Once he approves the PO, then only it should reach to the user in the 2nd level. And finally 3rd level.
Here Conditional Name is the best way to Log In or is there any other way to show the User based Log in Details, Because Here I am showing a List of Items Based On Log In, and Based On Log In user Has to view there List of Products and Status.
How to manage this situation.
Midhun VP can you please help me on this.

Yes, DNS is is fundamental for networks, even for Windows networks. The DNS is working well for the existing Windows network and there are no problems in distributing certificates etc.
There are more than 150 users and 180 devices on the network without DNS problems.
I don't know how to discover a DNS problem... Windows works well.
DNS resolves fine... dig does it for "a" records and "ptr" records. nslookup resolves, too.
When the problem is a faulty DNS, why does the usage of users/devices from OD work with Profile Manager?
Renaming and/or migrating the ActiveDirectory is not possible. First, I want to be sure that there is a faulty DNS.
The .local TLD is not optimal for Bonjour/mDNS but I can't believe that there is no workaround

Help! ADF default behavior rejected by end users...

Hi,
We have built an ADF 11g application during the past months. Last week we had our first user acceptance test with a small group of users. The users were very satisfied about the nice looks of the screens. But they had quite a lot of issues with the default behavior of ADF. I'll provide a list of the most important issues below. I hope more people here at OTN have experienced these issues and perhaps have some workarounds. And perhaps Oracle can use lists like this to improve the next version of ADF...
<ol><li>Multi record edit We have a lot of multi record edit screens. These are all editable tables. Those tables have the following problems:
<ol type="a"><li>Whenever a partial refresh occurs, the whole table gets reloaded. This takes some time, which is uncomfortable. But the main problem here is that the table does not preserve the scroll bar position. The situation can be improved a little bit by setting the <tt>displayRow</tt> attribute to <tt>"selected"</tt> on the table. This will cause the table to show the selected record at the top of the view port after a refresh. But this still confuses the end users. In their experience the records are randomly jumping around.</li>
<li>Records are not always inserted at the bottom. (In fact, they are inserted above the selected record.) End users simply expect records to be inserted at the bottom of the table, no matter what. And I can't disagree with them. Isn't there a setting to achieve this in ADF?</li>
<li>Whenever the user navigates to another record in the editable table, all validation rules on the record he navigates from are fired. That means he cannot leave a required field empty to fill it later. The end users say this is very annoying. We would like to delay all validation until the user presses the Commit button. But as far as I know this is not possible, is it?</li>
<li>The selected record position is not preserved on a full refresh. Our Commit button forces a full refresh of the page. This sounds like a sensible choice to me. However, users tend to click on Commit quite often. But after a full refresh of the page, the currently selected record in a record set is always reset to the first record in the set. In a large data table, this annoys the users very much. Isn't it possible to preserve the selected record over a full refresh?</ol>
<li>Annoying validation errors Many end users are annoyed by the somewhat "persistent" validation error messages. In a larger form or an editable table, users sometimes want to ignore an error and first enter other data, before correcting the error. This is hardly possible, because ADF sets the input focus to fields with errors and keeps popping up windows with a list of fields that have errors. We would like to make the validation less "aggressive". It is okay to give a field a red border if it contains an error. But leave the input focus where it is. And don't show any popup until the user presses the Commit button. And even then show the popup window only once.</li>
<li>ADF BC caching and business rules in the database We have some business rules in our database that automatically fill some fields with default values. We have e.g. a master-details relation, where a value in the master record is calculated based on the values of the detail records. We have set the calculated field in the master record to "refresh after update" and "refresh after insert". Sometimes the value of the field gets refreshed, but sometimes not. Users know that the field should be calculated by "the system", and are asking if they did something wrong if it doesn't. I know we could do the calculation in ADF, but our policy is to have all business rules in the database and to not repeat ourselves (DRY). Is there another way to guarantee that the calculated value in the master record gets updated after an update or insert of one or more detail records?</li>
<li>Partial refresh loses data If a field causes a partial submit to occur, fields in the same record that were not (partial) submitted before lose their data. This forces us to enable partial submit on all fields. But that causes a delay after moving the focus to the next field and validations to be fired too early.</li>
</ol>
I've numbered the items above, please use these number as a reference if you're posting an answer to a specific question.
Please let me know any solution, even if it is only a partial solution. We've a nasty situation now. Our application is (nearly) finished, but it is blocked for production by the users because of the behavior of the ADF framework, on which we have very little influence. We can't blame the users for that, most of their criticism is fully justified. So we have to come up with a good solution for these issues before we can go to production. So any help would be highly appreciated!
Best regards,
Bart Kummel
PS.
We're using JDeveloper/ADF 11.1.1.1.0, we deploy to a WebLogic 10.3.1 server and we have an Oracle 10g database. We're using the full ADF stack: ADF Business Components, ADF Bindings and ADF Faces.

Hi Bart,
I can answer for few of your questions.

End User Authorizations and Roles

Hi,
What all the authorizations i need to give to an End User, who uses the device.
Is it necessary for the userid to be same in MI Client, MI server, Backend systems.
Let me explain wat an end user does
>logs into MI client
>performs first synchronization
>Executes Mobile Application assigned
>and performs synchronization at the end of the day
rgds,
Kiran

Hi Kiran
Probably I wanst clear with my reply. You need to assign both the above mentioned authorizations to the same user who is performing a sync from the MI Client. S_ME_SYNC is required for the user to perform a sync from MI Client to MI server. S_RFC is required for the same user so that the data can be transferred from MI server to SAP backend and vise versa.
Hope I am clear now

End user migration

I am moving from a be5k to a be6k
I am also going from non LDAP to LDAP integration
The end users IDs in the current Be5k environment match the userId as defined on on LDAP
My question is what is the best way to accomplish this with the least amount of having to go touch every user ?
My thought was to do a user export from the be5k and import that on my be6k...(however, it appears that my Controlled device field does not make it)
and once I have all this turn on my LDAP sync.
It appears that the user then converts from a local user to an LDAP user as the user ID is the same---which is really awesome !
At least my tests seem to bear this out
If I can somehow get the controlled device field exported out then I think that this process would work
Anyone have any experience doing this and any best practices ?
Thanks in Advance
Pete

Small Business Deployment on End-User-Owned iPads/iPhones

Background:
6 employees (6 iPads, 5 iPhones) at an architectural firm
Need cloud-syncing of large PDF libraries of drawings and CAD files for use in the field
Office server is Windows Server 2003 (currently locked-down to local LAN & wi-fi only, no external access (boss' fear of security))
Office workstations are Windows-only (I've got Macs at home)
We have just been gifted iPads (personally-owned) to use for work/play and I received the tasks of setup & deployment. I would prefer to implement a controlled system to limit my headaches, this isn't entirely possible because these iPads were given as personal gifts and the employees would raise ****. After downloading/researching the Apple Configurator, it seems like it creates too much of a locked system - so end-users couldn't have their personal Apple IDs on their devices and buy/configure their personal stuff while being managed (work-purchased apps and PDF/CAD deployment) by me. Correct me if I'm wrong.
MDM implementations seem a little overboard. $$$
I have come across the iAnnotate app, which syncs with Dropbox (I can convince my boss to pay for Dropbox for Teams). While I would rather rely on an Apple-developed app (iBooks) to manage our library of PDFs, iAnnotate seems stable through user reviews. AutoCAD WS would be used for CAD files, with Autodesk's built-in syncing service.
1. My headaches aside, should I have each user buy/download/update apps with their personal AppleID and reimburse them (or gift them through iTunes from our corporate account)?
2. How could I control the wiping of a lost iPad/iPhone?
3. Any other recommendations for deployment in my situation?

boss would rather not have iTunes
The name is rather unfortunate in your situation. iTunes came out as a way buying music for the iPad. Apple had iTunes around, so they added features over time. It's now a device manager for all Apple i devices. It's more than a way to purchase music.
Do you take the iPad on customer visits. iTunes can load presentation on iPad.
If you sync the iPad on multiple computers, check this out.

End-User Agreement before opening a pdf file

Hi, is it possible to have an end-user agreement type thing come up when a user opens a pdf file which will only open the document if they accept the agreement? How would i do that?

You can fake it, either using JavaScript and a dialog box or script-controlled layers on the first page of the PDF; but neither method is even remotely-secure, and won't work if the user has scripting disabled or is viewing in a non-Adobe tool or a mobile device.

Unable to see ESS content with an end user

Hi All,
When I try to see my ESS content with an end user, it is giving me the following error:
com.sap.xss.config.FPMConfigurationException: Read of object with ID portal_content/com.sap.pct/srvconfig/com.sap.pct.erp.srvconfig.ess.employee_self_service/com.sap.pct.erp.srvconfig.skills/com.sap.pct.erp.srvconfig.fpmapplications/com.sap.pct.erp.srvconfig.skillsapplication failed.
Part of the stack trace also says,
Caused by: com.sapportals.portal.pcd.gl.PermissionControlException: Access denied (Object(s): portal_content/com.sap.pct/srvconfig/com.sap.pct.erp.srvconfig.ess.employee_self_service/com.sap.pct.erp.srvconfig.skills/com.sap.pct.erp.srvconfig.fpmapplications/com.sap.pct.erp.srvconfig.skillsapplication)
It is coming for all the applications in ESS.
I think it is a permission issue, so i gave the end user permission to the user in the PCD as well in the directory where all my ess contents have been kept.But still it doesn't work.
And only when I assign the end user with Admin right, it works which should not be the case.
Kindly suggest a possible solution for this.Your efforts will be appreciated.
Regards.

After changing a mail list name in Server end, users can't see the update in outlook client

Dear all,
This is a real issue. I am a Help-desk in a global company and after changing a mail list name in Server end, users can't see the update in outlook client. Even I download Offline address book in full detail, user still can't see the change in her outlook.
Does anyone know how to fix it?
Thanks,
Franklin hong

Hi,
Would you please detail what you did by "changing a mail list name in Server end"? What is the mail list and what server?
If you switch to Online Mode instead of Cached Exchange Mode, does the user see the change?

How to determine best User Device Affinity Settings

We've configured User Device Affinity for our site based on the canned defaults. Initially we started with 14 days and 1440 minutes. But after a recent deployment, we discovered that our Antivirus service account is registering as a "Primary User"
on all of our machines which has triggered a very bad situation.
My question is how do you determine these settings? My first try was to find a report that showed how many minutes each user was registering in the given period so that I could adjust it accordingly. I assume that my regular users are using the computers
a lot more than my service account but I have no way of verifying this.
I've tried combing through the security logs, but I'm not sure what SCCM is picking up on to determine the time period.
To me, it seems that 24 hours is a really low threshold and that I could bump that up to 120 hours over 14 days pretty easily without issue. My concern is that there is a reason that they are setting it so low to begin with that I'm missing. Even then, I'm
just randomly trying things hoping to get it right as I don't have the proper information to make the right decisions.
Any ideas? Feedback?

Yeah, I saw those logs but it still seems mysterious to me. I'm not sure where it's getting it's info. I assume it's the security log for each machine but I have nothing to confirm that. It's odd because our service account for our antivirus solution isn't
actually logging onto the machines so I'm not sure how it decides that this user is a primary user.
Ultimately, we worked around the problem by switching antivirus solutions but that won't be an option next time.
My guess is that we could have fixed our problem by adjusting our security logging settings in windows. But it wasn't something I wanted to do without direct confirmation with how this all works.
Thank you for your help on this though.

How to search for unused User Device Profiles in CUCM 10?

Hi guys,
I have a customer who would like to find out which User Device Profiles are not being used. I think the following methods would work but I have no idea how to do these in bulk:
1: Figure out if the User Device Profile is associated with a user or not
2: Figure out when the last time the user device profile was used (Is this possible? Direct database query? If so how?)
Any help would be greatly appreciated
-Akin

I had the same issue in my former company but luckily we used the "Login User ID" field wher we had the end user associated.
As soon as the User left the company and therefor was deleted in CUCM that field became empty.
So what I did was following
Generate a User Device Profile Report (Bulk Administration > User device Profiles > Generate UDP Reports
Select from the device fields Profilename and Login User ID
Let the report run and open the report file (you will find it at the job scheduler)
All UDP's without a login user ID are usually not assigned to a user and you may want to delete those.
No idea about the SQL query but you maybe find something usefull in the database dictionary http://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-programming-reference-guides-list.html
