Network segmentation policy and QOS settings on Nexus1000v
Hi all,
has someone an example on applying QOS (marking cos) using a network segmentation policy with NSM feature enabled and VshieldManager/Vcloud on Nexus1000v?
I'm using the current default policy
network-segment policy default_segmentation_template
description Default template used for isolation backed pools
type segmentation
import port-profile NSM_template_segmentation
port-profile type vethernet NSM_template_segmentation
no shutdown
description NSM default port-profile for VXLAN networks.
state enabled
port-profile type vethernet <NSM Created>
vmware port-group
port-binding static auto expand
inherit port-profile NSM_template_segmentation
switchport access bridge-domain "xxxxxxxxx"
description NSM created profile.
state enabled
But Now i need to configure a cos marking for some org id (not for all organizations).

CRM Target Groups and Product Segments - BW and BPS settings
Hi gurus,
I have some questions regarding the CRM Target Groups and Product Segments as it relates to BW and BPS planning layouts.
1. When a target group is created in CRM, is it supposed to also be create master data entry for the object 0TGGRP_ID in BW? If it is, what kind of settings need to be made to ensure that? When we create target groups in our CRM instance, we donu2019t see the master data being updated for the 0TGGRP_ID info object.
2. Where exactly (in BW) is the relationship between the target group and the underlying customer/business partners stored/updated? We have a requirement to use target groups for defining the trade promotions and still being able to explode and plan on (individual) customers in the embedded BPS Planning layout. I believe that we need to have target group and associated customer assignments stored somewhere (?) in BW and use BPS characteristic relationships to populate all the possible combinations for a target group ID being passed from CRM. Am I correct in my assumptions? Any ideas if SAP has already delivered something similar in the BPS business content for TPM?
3. We are planning to use product segments to define the trade promotions as well. I believe BW info object is 0CP_SEGMENT. Similar to what I mentioned in Question 1, I donu2019t see any master data being updated for 0CP_SEGMENT. Am I looking at a wrong BW object or missing some key settings?
4. Where is the relationship between a Product Segment and the associated products stored/updated in BW? How do I create a trade promotion using a product segment and make the BPS planning layout populate individual products in the lead column?
Thank you for your helpHi Anna,
After reading your post, what i understand is that there is no existing relationship present in CRM system between the Org BP and the contact person BP.
As per my Knowledge in order to create a Target group with Contact Persons you should have an active relationship persent in the CRM system bewteen the BP and the Contact person.Now as your sceanrio suggests that the Contact person's are present in the BW system but not in CRM, i would assume that the relationship also exsits in the BW . So if it does then your BW team should be able to help you in creating the necessary infocube with there analytical tools and you can then use there cube as the datasource and create the necessary Target Group with Contact persons.
Comming to the second part of your question, your guess is absolutely right but to give you more detailed infomation , the BP ID is converted in a unique GUID and this is passed into the program to retrive the necessary information from the BP after the campaign is executed.
Hope this helps!!

after upgrading to IOS 5.1 I no longer can see Verizon at the top of my Iphone and under settings>general>Network>says Not Available Why is this? Did the upgrade cause this?
steveSee this tip --> http://support.apple.com/kb/TS1559
If this doesn't resolve it you most likely have a hardware failure. Fortunately, your phone is in warranty, so if you take it to an Apple store they will replace it. -

my ipad2 is unable to find wireless network(s). while at home I am able to connect my MacBook and iPhone to network but am unable to connect iPad. I have restarted the device multiple times and even reset the network and all settings but still no luck
Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Try this first - Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
This works for some users. Not sure why.
Go to Settings>General>Date and Time> Set Automatically>Off. Set the date ahead by about a year.Then see if you can connect to the store.

Everything I look up for Event ID 1085 seems to be about a different cause.
Any ideas?I enabled tracing on a domain gpo and I still get the error when running gpupdate /force .
I'm also still getting Event 1085. Here's the trace file. I've anonymized the site/domain and the GUIDs.

My carrier is Straight Talk (using ATT network) and they require the user to enter the APN settings in order to access their data network. My Iphone 4s is factory unlocked but I can not get to the Cellular Data Network tab to enter the settings?
Yes ATT hides the APN settings so when you try to use a st sim it automatically reads on AT&T network so the APN settings are hidden and cannot be accessed however you can go to apn.straighttalk.com on you'r phone and select APN/data settings then select AT&T then iPhone and a screen will pop up asking if you would like to install the profile for whatever reason it's not verified but works fine. You can also go to www.unlockit.co.nz and set up a straight talk APN profile that is verified not sure exactly what that means but both work to get the data working on the phone for straight talk but it does not make the MMS work. There are a couple other methods I have read about one is on howardforums using ibackupbot to manually change the files on the phone I haven't been able to get mine to stick using that method but other people have and there is a sim swap method to trick the phone to reveal APN settings using a tmobile sim I have not tried this but other people have with success. The last two methods mentioned will make both data and MMS work

If you cannot remember the passcode, you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and resync the data from the device (or restore from a backup).
If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present.
You may have to force iPad into Recovery Mode

Hello there, JP3199.
You've mentioned a few issues in your post so I will try to offer up some recommendations for troubleshooting each. In regards to the issue of not powering on unless plugged in the following Knowledge Base article offers some practical steps to try:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/ts2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
My issue is still not resolved. What do I do next?
Contact Apple Support.
In regard to being unable to turn on Wi-Fi, if you mean that the button is grayed out, then this article should prove useful:
iOS: Wi-Fi settings grayed out or dim
http://support.apple.com/kb/ts1559
Follow these steps to resolve the issue:
Restart your iOS device.
Make sure that airplane mode is off by tapping Settings > Airplane Mode.
Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
Make sure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.
If you still can't turn Wi-Fi on, please contact Apple for support and service options. If you can turn Wi-Fi on but are experiencing other issues with Wi-Fi, see how to resolve those Wi-Fi issues.
Lastly, this article should help with troubleshooting cellular network connection on your iOS device:

I have two facetime users, both connecting to our enterprise wireless network (Cisco WCS) and they can't make a facetime connection from IPAD to IPAD. Are there any apple protocols or other settings that need to be enabled on WCS? There is no firewall inbetween the two connections, as this is all on our internal network.
Both devices can connect to the network, but when they try to talk to each other they can't make the connection.
Thanks.If anyone ever comes across this and has the same issue, here's what I did to fix it:
My Linksys router has a Network Mode setting, and I had to change it from "Mixed" to "Wireless-G only". (I would've used N but one of the NICs in my house is too old to support it.) Anyway, after making this change, Facetime works fine on the phone. Hope this helps someone else! -
I use IMAC upstairs connected to the house wifi downstairs where the networked printer is. I have 'found' the network printer on my IMAC settings but when i send to print I am getting a pop-up box which has 'apple' as user name and is asking for password. I have tried my own IMAC password but to no avail. The printer also shows a pop-up box stating 'awaiting authentication.
Any help appreciatedYou are asking several different questions. If you need to store your photos, music, and movies on an external volume, you certainly can. Any externally connected hard disk drive will work, connected either directly to your Mac or to your Time Capsule as a shared volume.
You should not rely upon using that as a backup device though. Although you certainly may use it for both purposes, it is a better idea to have dedicated backup devices for a variety of reasons not limited to redundancy. You would not want to simultaneously lose all your pictures as well as your backup. If they are all on the same device, that could happen. Furthermore, a backup cannot back up the volume on which it is running.
As for adding an Extreme or Express, using its LAN port for your iMac, and then enable Internet sharing so you can effectively use the iMac as a "hotspot", you can do that too, but I am unclear on what benefit you believe this arrangement would convey for you.
An Extreme's Guest network is separate from its Main network; that is the reason for having it. -
'Vintage' MacBook has lost all wifi connection suddenly and stored settings. I've tried to manually input my IP address and DNS number but it just times out when trying to connect to the network can anyone help?
You said:
We still couldn't get it to stop timing out. I tried to download the firmware from iClarified but iTunes said it didn't recognise the software.
Just what did yo do to gt iTunes to see the download: -

BrianIn order for networking device to classify traffic, there is certain information within a frame or packet to identify the importance of a frame or packet. CoS, IP Precedence, and DSCP are widely used nowadays.
CoS is in layer 2. IP Precedence and DSCP are in IP header.
In a dot1q tag, there are 3 bit used to identify the importance of the frame. As CoS is 3-bit, the range is between 0 to 7. In normal Cisco VOIP implementation, Cisco IP phones mark CoS 5 on RTP frames. Data traffic is put on native VLAN; so that there is no 802.1q tag on data traffic. By default, Cisco switches put any traffic without 802.1q to be CoS 0 and DSCP 0.
Before DSCP is used, the second byte in IP header is called ToS (Type of Service). It was used to classify IP traffic. Like CoS, IP precedence is 3 bits. Thus, the range for IP precedence is 0 to 7. After a while, we find out that 3 bit is not long enough. We expand IP precedence from 3 bites to 6 bits. It is called DSCP. As DSCP is 6 bits, the range is 0 to 63. Normally, Cisco IP phones mark EF (DSCP value 46) on RTP packets.
QoS on campus switching is different than router. In router, we normally mark and police the traffic just before going to ISP. As a result, you determine what traffic is dropped if the traffic going to ISP exceeds the bandwidth of the circuit.
We normally classify traffic on ports connecting to phones and end devices. To simplify configuration, Cisco switches allow you to trust CoS; so that VOIP traffic is classify with CoS 5. Different switches have difference queues. However, all Cisco switches put CoS 5 or DSCP 46 into priority queue. Once traffic is classified on the access switches, we can simply trust DSCP or CoS on the links between switches. We should use trust DSCP on any layer 3 links. Also, make sure that voice VLAN is not used as native VLAN.
The last question is what happens if a users put a data device on the voice VLAN and construst frames with CoS 5. Here comes extended trust. Switches have to receive CDP on the port before trusting the device on the voice VLAN is a VOIP phone. Not sure if I miss anything.
