Logical Network - Cloud

I have a defined a Logical Network and have added a Site into it. Also, I added a pool of IP Addresses as well so that whenever a Virtual Machine is being made through VM Templates, IP Address is available for it.
I am unable to see this Logical Network in the Cloud. There are currently two Logical Networks, default one and the one that I created. I can only see the default Logical Network in the Cloud and cannot see the Logical Network that I created. What
could I be Missing?

The logical network(s) are associated with host groups, so ensure that they are associated with the host group(s) you have added to your cloud, or else they won't be visible.

Logical Network not showing up in Cloud Settings

In my SCVMM environment, I had the default Logical Network that gets added as soon as you add a cluster or host into it. Since, I wanted more Networks like DMZ Network and Networks based on Departments, I went ahead and created those in the Logical Network
and defined IP Pools in it so that When I provision a Virtual Machine through Windows Azure Pack, Users can be see all the Networks.
I am facing a problem when I try to add the Logical Networks in the Cloud. I am only seeing the default Logical Network and unable to see the Logical Networks that I created manually? What could be the reason? How can I troubleshoot it?

I don't know if they have been uploaded or matched. I did see the tracks on my phone of the new album I imported into my computer. So I think some syncing has ocurred. But there is no download button on my phone like there is for other tracks I have uploaded. All the tracks are greyed out and I can't play them on my phone? Any ideas?

Logical Switch and Logical Network

Hello All...................I have Hyper-V Failover Cluster based on 5 Hosts and I am managing it with VMM 2012 R2. I was slightly confused with respect to Logical Network and Logical Switch in the Fabric Settings. I would appreciate if someone could
shed a little light on the difference between them. Also, while there is a Logical Network defined by default (Name of the Virtual Switch of Hosts), there is nothing defined in the Logical Switch. Which one is mandatory? Logical Network or Logical
Switch? Can I delete the default Logical Network?

Hi Nick,
Please find below link for the whitepaper mentioned by Kristian.
https://gallery.technet.microsoft.com/Hybrid-Cloud-with-NVGRE-aa6e1e9a
For a complete reference please refer below series. This covers VMM 2012 SP1 but should be fine with R2 as well.
http://blogs.technet.com/b/scvmm/archive/2013/01/08/virtual-networking-in-vmm-2012-sp1.aspx
Logical Network is defined for easier management and used in Network Virtualization where as Logical switch is used to configure networking in multiple Hosts rather than creating individual Virtual switches in each host. If it were me I'll leave the
default logical network as there is no harm of doing nothing in it.
I hope this will shed some light into your situation.
Thanks,

Removing Logical Networks and Subnets from Hyper-V Host Network Adapters that are greyed out

Hello All
I am new to SCVMM 2012 R2 and I have create a Hyper-V Cluster and now creating Logical Networks and Port Profiles and Logical Switches. I have figured out how to create all of them properly now, but I have made some mistakes in the past. I have a Logical
Switch created and assigned to network adapters on the hosts. Now I am trying to add the other switches to other adapters, but I have associations on network adapters to Logical Switches and Subnets that are not correct and need to be removed so I can add
the correct ones, but in the console the network adapters that I need to work with the information is grayed out and I can't change the information.
I am not an expert at Powershell. Below you can see a Logical Network and Sunets associated
to a Network adapter. Can someone help figure out how to remove the information so I can assign the correct Logical Network?
I woul so much appreciate this. I know there is a way to do this in
PowerShell but I don't know Powershell that much. I
am savoing all the
powershell scripts ever time I configure something in SCVMM but I have had no luck trying to
revearse what I did.
Help Please

This shows that an Uplink profile associated with this host, links to these logical networks. In order to remove this successfully, you must remove the logical switch and uplink deployed to the hosts.
For a complete overview and guidance on the required configuration, have a look at the whitepaper we created.

Logical network to physical network mapping (subnets and VLANS) in SCVMM 2012 R2

In much of the blogs, documentation and literature on VMM, there are examples of deploying multiple logical networks onto one physical network i.e. Cluster (logical) + Storage (logical) + Backup (logical) + Live Migration (logical) + Management
(logical) on top of Datacenter (physical).
Does this mean it would be possible to have one (physical) flat VLAN-less network with one subnet and then have all those logical networks (with subnets and VLANs) on top of it? Even with a simple unmanaged L2 switch that doesn't support VLANs itself?
If not, just how do you map multiple logical networks to just one physical network? How does that work in practice? Is a L3 switch needed to route traffic between logical networks for example?

Hi. VMM Networking may be overwhelmed for the most, at first. But you really need to understand the modeling here and how things are related to each other. Especially if using NIC teaming in WS 2012 (and R2) together with this mix.
I suggest that you read the following whitepaper where we explain how to setup networking in VMM (also to support network virtualization, but that is absolutely not mandatory): http://gallery.technet.microsoft.com/Hybrid-Cloud-with-NVGRE-aa6e1e9a

Logical Network issue

I am using SCVMM in windows 2012 R2 standard and Hyper-V role enabled in Windows 2008 R2 sp2.
I've created logical netwok in VMM but here it is not deploying the local switch in hyper-v, I need some assistance on logical network communication between vmm & hyper-v.

It's hard to tell where you are in the jungle of configuration here, but I would recommend you to read the following whitepaper which covers the entire setup of the logical network/logical switch deployment to the hosts:
https://gallery.technet.microsoft.com/Hybrid-Cloud-with-NVGRE-aa6e1e9a
I did also do this session at TechEd last year, showing how this should be deployed from the ground up:
http://channel9.msdn.com/Events/TechEd/Europe/2014/CDP-B327
And last but not least, here's a Powershell script (purely demo based, unpolished, ripped rout out of an open - ongoing editing ISE session :-) ) that shows how these things are related to eachother:

One logical network per VLAN?

I am not using network virtualization and currently using traditional VLANs. Now what I did currently is I have one logical network, one network site, and in that network site contains all my VLAN's (23 right now).
What I noticed is when I create a cloud I can't choose the network... I can only choose the logical switch which will give that cloud complete access to all VLAN's right?
So in my situation would it be better to just create a logical switch for each VLAN we have? Keep in mind this is a multi-tenant environment so that is why there are so many VLANs.
Most of the videos I find go into Network Virtualization which is not what I'm trying to do :-(

Hi se
This is how I do it (I don't have WLSE):
- Create a ssid per vlan in the AP.
- Configure switch to AP connection as a trunk.
- If needed, configure helper addresses in switch.
If you need routing between VLANs, you will need a router, afaik AP cannot do it.

Bare Metal Deployments: The BMC can't have IP Address defined in logical network?

I have defined a logical network, a logical switch, and a port profile. I apply the logical switch (the NIC teaming settings) and a virtual network adapter that inherits the hosts network configuration (pass through config. no software defined networking)
to each of my Hyper-V hosts successfully.
The issue occurs once I have defined that logical network, I can no longer deploy bare metal hosts because the BMC obtains an IP within that logical network. You see the BMC IPs and NICs are on the same subnet/VLAN.
What's the best practice or perhaps best method to get around this issue?

I am not sure if I follow you on this one.
You have created a logical network for your BMC in VMM? If so, why have you done that?
The bare-metal process requires both PXE and
DHCP during this process, and the scope should therefore be in DHCP and not VMM for this purpose.
Can you try to do that? (If this is a lab environment, you could add the DHCP service to your PXE server or even VMM server).

Logical Network question

I created a logical network on one of my OVS 3.1 servers, but I'm not sure how to use it. I already have a standard network created for my VMs but I thought that I could use a logical network for the VMs on one physical server to all talk to each other more efficiently. I just don't know how to make that actually happen.
After I created the logical network my VMs on that server all created an eth1 device. I haven't done anything to further configure eth1 on those VMs and I'm not sure what I should do. Has anyone used a logical network in OVS effectively?
Here's an example of the ifconfig output for eth1 on one of my VMs:
eth1 Link encap:Ethernet HWaddr 00:21:F6:AA:00:19
inet6 addr: fe80::221:f6ff:feaa:19/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:100 errors:0 dropped:0 overruns:0 frame:0
TX packets:27 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:6600 (6.4 KiB) TX bytes:5927 (5.7 KiB)

My understanding is that you would go into Networking, and select the network where these servers all exist... and remove the VM role from that project. Then you can add these servers to the new network.
But you may not be able to do that with the servers up.

Creating Logical Networks and Switches via SPF

Hi,
Is it possible to create Logical switches and logical networks in VMM by calling SPF REST APIs. I can see only a GET API for logical networks and none for Logical switches. If they exist can someone point me to a link to the documentation?
Thanks,
Venky

Hi
You can only get logical network information -
http://msdn.microsoft.com/en-us/library/dn470018.aspx
The purpose of SPF is to be used as web service for Tenants. As logical networks and switches are objects that are maintained by administrators they cannot be managed by SPF. Logical networks have get operation because you might want to create VLAN-based
VM Networks depending on what is configured in Logical networks. For administrating logical switches and networks administrators will use PowerShell or the VMM console.

Logical network advice

Hello Guys
I have recently installed scvmm 2012 r2 and would like to manage a few hyper-v hosts etc...However since installing i have realised that i may have a problem setting up the logical networks. Let me explain. Currently our department shares a large network
with other units with the overall dhcp and dns structure being outside my direct control. for example, we get assigned an ip based on the mac of the vm, client or server. now this has implication when it comes to creating the ip pools etc...in vmm, since i
dont want to have it assign ip's to machines that have already been assigned ip's by the main dhcp pool (i.e. want to avoid conflicts).
is there a way in which i could still make use of scvmm in this case?

Hi

Removal of Virtual Switch Logical Networks

Hi,
I've recently managed to get SCVMM 2012 R2 up and running and it's currently managing 2 hosts in a cluster. I've migrated both hosts onto a logical switch, and I'm now at the stage where I'm ready to delete the LN's created for the per-host switches. I've
deleted the Virtual Switches and deleted the VM Networks associated with the switches successfully, but when I go to delete the LN's associated with the Virtual Switches, I get a 25100 error.
In dependencies, it shows that each LN has one of the hosts as a dependency but when I log into the hosts, there's nothing to indicate that they're in use. Is there any way to fix this or do I need to manually delete them from the database?
Cheers,
Ed

Hi Sir,
>>In dependencies, it shows that each LN has one of the hosts as a dependency
If you mean this :
Please open the hosts' properties then check the hardware option and uncheck the "logical network connectivity":

Chaning the Logical network of a VM network

I have 3 x 2012 R2 hyper-V hosts in the same data centre.
They are stand-alone and some virtual machines use Hyper-V replica.
Each host has 4 NICs, 1 for management (not available to Hyper-V), 1 for "external" services (physically plugged into DMZ switch) and 2 for internal services.
In SCVMM, under the "VM Networks" node, I can see External, Internal1 and Internal2, each are associated with a logical network that auto-created by SCVMM.
I would simply like to use "External" and "internal" as my logical networks. I have created these logical networks, associated the IP ranges, but am unable to change association in the "VM networks" area.
What am I doing wrong ?
Thanks.

Hi Sir,
Yes , you can not change that association in "VM networks" .
I would suggest you to refer to following article regarding " Configure NIC teaming using VMM ":
http://blogs.technet.com/b/privatecloud/archive/2013/04/03/configure-nic-teaming-and-qos-with-vmm-2012-sp1-by-kristian-nese.aspx
It will help you understanding the function of common "network configuration" part .

How do I get ipackets and opackets statistics for logical network interface

I do a kstat_lookup() and kstat_read() to get the ipackets and opackets statisti
for the physical network interfaces like hme0.
However those statistics are not available via kstat for logical interfaces such
as hme0:1.
I notice that netstat -ai reports numbers for ipackets and opackets for
logical network interfaces so that information must be available
programatically but where?

netstat(1M) uses private ioctl(2) calls to a prepared /dev/arp to extract SNMP MIBs
that contain this information. I agree that it should be published via the kstat interfaces
as well.
