Does ACI support a VXLAN Tunnel between Leaf(Leaves) and VMware-vDS, and MS-vSwtich?
Hi Experts,
I have a quick question about Normalized Forwarding of ACI Fabric.
Does ACI support a VXLAN Tunnel between Leaf(Leaves) and VMware-vDS, and MS-vSwtich? Otherwise any plan to provide that function in the future?
If there is no function and plan How is Normalized Forwarding possible with VXLAN headers that are generated by each Hypervisor? Of course I know it's possible for a VM on ESXi to communicate with another VMs on Hper-V without VXLAN but I just focus on Normalized Forwarding between Multi-Hypervisor.
Or If AVSs are implemented on ESXi and Hyper-V repectively, is it possible to make a VXLAN Tunnel between Leaf(Leaves) and AVSs on ESXi and Hyper-V? And what is a example of that usage?
Thanks in advance.
Paul
Hi Paul,
As I understand, ACI Leaf to the VMware-vDS is still vlan so no tunnel for VXLAN. When we integrate Vcenter with the ACI, We define the vlan range for the traffic from VM-ware-vDS to map EPG to a VMware ESXi port group.
For the MS-vSwitch, As It support OpFlex agent could act as VTEP but not part of the fabric. But I am not sure about this.
As AVS is part of the fabric so It will act as a VTEP (VXLAN Tunnel between Leaf(Leaves) and AVSs)
But what is the benefit are you looking? Traffic normalization is still there because Traffic within the fabric is encapsulated as VXLAN. External VLAN/VXLAN/NVGRE tags are mapped at ingress to an internal VXLAN tag.
Note:the VLAN ID has local significance for the leaf node
Regards,
Anser

my host name changes every few days, since Xmas adding a macbook its changed 6 times. Do I need to stop this? Does it cause problems with sharing between the iMac and macbook?
There are several possible causes for this problem.
1. Two (or more) computers on the local network have the same Bonjour name, such as "X's-MacBook-Pro.local".
2. You have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.
3. A Mac wakes from sleep due to network traffic. This is due to a bug in OS X that may only affect some models.
4. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
5. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.
6. See also this support article.

Is there a way to Move files to the iCloud thus freeing up disk space on my Mac? Or does iCloud only sync (replicate) files between my Mac and the cloud? I want to free up disk space on my Mac and assumed that the icloud would be a good way to do this, but having 'moved' 70Gb of files to the iCloud drive (I've upgraded to 200Gb storage) my Mac is still nearly full and I've realised that it seems to just Sync files just like dropbox.
So, the big question is did the Apple guys confirm that this is how the new iCloud drive should be working? I'm guessing, from your response, that this is indeed the case. Are they going to fix this anytime soon? I thought that this was a new function of the iCloud drive in Yosemite.
I just want an online storage facility to back up my photo & music collections. I did look at Dropbox as they have a good deal going with their Dropbox Pro, however this is still just a sync service where the Master files reside on your local disk drive - although I have read that there may be a way to work around this. Still not ideal. -

Does itunes support intel x3100 graphics for watch video and tv shows in itunes: not working
Hi I have a asus p5k-vm motherboard with intel 3100 onboad graphics accelerator. I had a gtx 570 video card install and was using itunes
to watch video and tv shows. I sold my gtx 570 and I am using intel x3100 onboard graphics accelerator as my video card. Everything works
fine until I try to watch video or tv shows in itunes. When it tries to start, the screen starts and then right awat it stop and shuts down becuse of some error. I don't know what the problem is.
Please help.Since updating to 5.0 numerous people have had an issue with optical out. . Try Restart your ATV & computer. Also cycle the power on the ATV and TV (unplug it for 30sec). You should also submit a bug report directly to Apple since they DO NOT read these forums

L2 tunnel between me3600x and 3925
Hello,
We are currently trying to configure a l2tunnel between a ME3600X (running 15.3(3)S3 with the AdvancedMetroIPAccess licence) and a 3925 (running 15.0(1)M2 with the datak9 licence).
We are part of a CsC architecture, playing the role of the customer carrier, using BGP for label distribution between the Backbone carrier and the Customer carrier.
Our architecture is quite flat as the CE and PE roles are on the same routers.
we have the view on the following architecture and can configure the R1, RCV1, RCV2 and R2 routers :
R1 --- RCV1---(Backbone Carrier)---RCV2--- R2
We have 3 sites A,B and C but only 2 dark fibers to connect them.
We are using the CsC to build a L2 tunnel and close the triangle :
A-ME=tun=3925-B
df df
C
For year were using a 2911 and a 3900 to build the tunnel and it was good. The tunnel was build with an xconnect l2tpv3.
we replaced our 2911 for a ME3600X few weeks ago following the advice of our backbone CsC contact, and we are now facing the following problem :
the configuration we used is not working any more : we can build the tunnel but the spanning tree BDPU are not passing through (We use rstp for spanning-tree protocol).

As we have no experience with the ME3600X and their EVC and service instance concepts we have a hard time figuring out what solution to use :

- According to this one it seems possible to interoperate a tunnel between a 2911 and a Me3600 : https://supportforums.cisco.com/discussion/11848451/eompls-and-layer-2-tunneling
Our need is slightly different though, as we are trying to pass a dot1Q trunk in the tunnel.
We tried to switch to encapsulation mpls, with no luck so far...
Any help or feedback would be greatly appreciated.

-> The "sequencing both" is mandatory to get the tunnel UP.
-> I configured l3 interfaces on the devices facing the ends of the tunnel and I can't ping them. Looking a little bit more carefully, I noticed that the arp table does not fill on the 3900, but it does on the 3600. I guessed that's a limitation on the 3600, but still not sure.
I then tried to switch to mpls encapsulation with the following configuration :

Actually, as I am in a CsC architecture using BGB for label distribution with the CsC core, there is not ldp neighbor, and it seems to be the reason why I can't get the tunnel UP.
I am now trying to avoid ldp for the signaling of the tunnel using AToM Static Pseudowire Provisioning but I am to much of a newbie for that. I get a "Incomplete AToM manual config" when configuring the xconnect on the me3600...
Here is my config on the ME3600x so far :

Funny, I tried to configure

on the xconnect sub config section of the interface, but it won't appear in the config...
I am really stuck, and any help would really be appreciated.

Also in ecryption its says encryption 3DES-CBC
i am not sure if this CBC is the culprit. Because thats what watchgaurd uses only it does not have an option for only 3DES.
strange enought that Phase 1 is getting up, I am also questioning myself about the following message appearing in Phase 1:

how come Phase 1 is coming up though the PIX is claiming that his HASH is not the same as HIS HASH :(

Hi folks -
I've read through some threads regarding "Your client does not support opening this list with windows explorer" and it seems a lot of folks have a lot of solutions throughout the forum posts. Is there anything official or semi-official regarding
this?
I've tried a lot of the fixes including:
checking to see if the WebClient service is on
modifying so-and-so registry (I've since changed them back since they seem to have no effect)
and changing various settings in Internet Options including making sure the site is in the Local intranet zone.
I could live without this functionality but just recently my upload-multiple-files functionality in SharePoint 2010 has also gone away (red x instead of directory UI). I wonder if it's related somehow and could give us a clue.
If it helps I'm using various browsers but of the IE flavor 8 and 9 32-bit as the base for testing this.For SharePoint 2013 (so could apply to 2010 as well), my problem was that I was trying to "Open with Explorer"
something that probably can't be opened with Explorer. In my case, I just wanted to open my team's Shared Documents with Explorer. I found that when I first log into SharePoint and view the page, I'm presented with those Shared Documents, but also other things
as well.
To get "Open with Explorer" to work, I must click "Shared Documents" under the Libraries heading on
the left. Then, all the other stuff (Links, Getting Started, etc.) go away and I'm focused on my team's shared documents. From there, I can go up to the Library Tools section in the ribbon, choose the Library tab in the ribbon, and click Open with Explorer.
Works like a champ on Windows 7 64-bit, running IE 9 32-bit.
Unfortunately that's not what was going on in my case. One obvious way to check is to see if other people or other computers can Open with Explorer. In my case it was just this one machine on my desk that had the issue. -
Pages 5.0 version does not support pictures in header
I recently installed new soft OS X Maverick and along with this also renewed soft for Numbers, Pages, Keynote, and some more apps.
Pages version 5.0 does not support its earlier version pre-set headers and footers. All the logos (picture files) I had inserted for my company template in the header are gone and I cannot re-enter them either. Does anyone can give e a hint on how to use picture files in Pages version 5.0 templates?
This is first time in 2+ years that I prefer to use MsWord over Pages on my Mac, which is a pity.
*I have tried to get used to new soft versions of numbers and pages now for around 3 weeks but it cannot make me to change my opinion that the eralier versions were much better. Unfortunately with OS X Maverick I have to use new versions for these apps, or do I, any hints?
I already deleted once (2 weeks ago) OS X Maverick and switched back to OS X Mountain Lion (I use TM), but then decided after while to still update the op system soft to newest one available, as I've hoped that developers in Apple will come up with their soft improvements and bug fixes soon enough.
Among the other disomforts (like pages, numbers and changed tag system) Safari is much slower than with previous version.
Any hints are appreciated!

Does it support - million orders per week?
Hi friends
does sap support million sales orders per week?
and if so how to do that?
Thanks
PrasadHi
SAP will definitely support this, but the question is whether the organisation can produce/procure and manage such huge amounts of inventory. I really doubt why an organisation should create 1million orders per week i.e. 52 million order per year.
If you can explain you need so many orders, it will be useful to us.
This may also affect the system performance based on the servers, location etc.
Reward if this helps.
