SCVMM 2012 R2 – two iSCSI network interfaces connected to the same subnet

I would like to configure two networks in SCVMM 2012 R2 which will be used by VMs to connect to iSCSI SAN. Both of these networks should be connected to the same subnet (192.168.100.0/24) because they will connect VMs to Dell EqualLogic using iSCSI MPIO.
Those networks should be available on all Windows Server 2012 R2 Hyper-V cluster nodes.
When I try to create two logical networks in SCVMM with the same subnet, I receive error (Unable to assign the subnet 192.168.100.0/24 because it overlaps with an existing subnet)
How should I configure networking in SCVMM to allow one virtual machine to connect to the same subnet using two network interfaces?

"How should I configure networking in SCVMM to allow one virtual machine to connect to the same subnet using two network interfaces?"
You can achieve this by simply adding multiple vNICs to a VM - connected to the same VM Network.

Solaris 8: Multiple primary interfaces connected to the same network

I have a machine with Solaris 8, and it has multiple interfaces that are connected to the same network which means they all have metric 0 (1 hop) to the default gateway.
assume:
e1000g0: 192.168.30.70
e1000g2: 192.168.30.72
e1000g4: 192.168.30.74
e1000g5: 192.168.30.76
gateway: 192.168.30.65 (Cisco Router)
However, it seems like despite the fact that they have a direct connection, they seem to be using e1000g0 to access the 192.168.30.0 network to get to the default gateway and then to anywhere else.
When I send a ping to say, 192.168.30.74 (IP of e1000g4) and capture packets on e1000g0, I see the "echo reply" messages going out of it as opposed to e1000g4 even though e1000g4 is the one receiving the "echo request". This should not happen and these should be completely independent as they should all be advertising a 1 hop to that network
The outputs from netstat -rn and ifconfig -a are shown in the picture on the link below
[http://img836.imageshack.us/img836/7308/ifconfignetstathiddenip.jpg]
This gets even more confusing when I go into the Cisco router and run the command: "show mac address-table" where only the MAC address of e1000g0 is shown for the switch port it's connected to, but not for the other interfaces which are connected to the switch. Yes, all ports are active (no shut) and are pingable.
Also, the odd thing is that ALL of these individual MACs show up in the router ARP table when the machine comes up, however after sending a ping to one of them, after a certain expiry or whatever period, the MACs disappear from the router ARP table and only the MAC for e1000g0 shows up. The arp table of the solaris machine however shows all the relevant MACs of each port of the router that it's physically connected to (This is actually a Cisco Switch with the advanced IP services imagine and L3 routing turned on)
Before anyone asks: The setting local-mac-address? setting does NOT exist in my machine and it never has, but it used to work fine. Also, from the ifconfig command, once can tell that all the MAC addresses are fine.
I need to somehow assign all these interfaces equal priority and make them understand that they're physically connected to the 192.168.30.0 network and there's no need to go through e1000g0 to get to it.
This is causing a lot of problems as eventually all traffic will end up going through the e1000g0 interface and that will become a bottle neck.
Please help Thanks in advance

Ok thanks. That was a useful response.
I did think about the trunking software that is claimed to be available for Solaris 8, but it's only available if you've got paid support contract. Oracle came and ruined everything re: Sun support which is so expensive now.
The other confusion is, we never had that OR needed to configure trunking/link aggregation on this machine, so why now?
Lastly, by your explanation, this should be expected and is "normal" behaviour, which would mean that this machine was always doing this and I only just noticed it this time? I thought if you turn off ipv4 forwarding and router function in the machine, it's every interface for itself. But it's not doing that :(
So then the question is, Can I force it? I've tried a bunch of things by manipulating the tables and it seems to mess things up where nothing is getting through or it now shifts all the traffic to some other port make the problem no different
Is there a way to give equal weight to all interfaces for the traffic to go directly through them that is originating at those ports?

Why can't Apple TV's and iOS devices see home sharing on my Windows 7 computer when iTunes libraries on other computers on the same network and connected to the same Home Sharing can?

I have never previously had any problems with Home Sharing, I have always found it to be completely reliable as advertised. I have 2 computers in the house, (one MacBook and one Windows Desktop) connected to the same Home Sharing account, connected to the same BT Home Hub 4. My situation is that I have nearly 2TB of data of which I would like to share with the home wirelessly, in my mind the desktop is the logical place for this to be shared from.
When running, iTunes on this desktop broadcasts to other iTunes libraries, but no other iOS devices or Apple TV's connected to the same Home Sharing account cannot see it.
I have tried turning Home Sharing off, and then turning it back on, closing iTunes, restarting the computer, going to Network and Sharing Centre and unticking IPv6 in the network adapter properties, even completely wiping the computer and reinstalling Windows 7.
One of the Apple TV's in the house was recently purchased by my parents with the promise from me that everything would work seamlessly... so far it isn't and I am frustrated that the Apple technology that I have come to rely on isn't working as expected.
One thing that has occurred to me upon writing this is that it is a very large amount of data, and I have not attempted to share this with another computer that is currently working and broadcasting it's Home Share fine.
I am sorry if I have ommitted any important details, any further questions don't hesitate to ask. I would be so grateful of any suggestions, my parents are depending on me.

I have found with AppleTV that it is the IPV6 on the computer you want to access is the problem. The issue is that Homegroup on Win 7 or Win 8 requires IPV6 to work, but AppleTV won't work with IPV6. (So maybe double check you have IPV6 turned off)
So you have to make a choice - Homegroup or AppleTV.... but you can't have both, until Apple brings ATV up to date. (crazy that it does not recognise IPV6 - c'mon Apple!)
You can set up sharing individually in Win 7 or 8 and have the ATV access files that way.
Having said that, there is always the exception.. I have an old HP home server running Win8 and it services ATV - but is part of the Homegroup... have no idea why it works on both, but no other machine on the home network will talk to both ATV and Homegroup at the same time!

How do I load balance TFTP between two servers and a client on the same subnet?

Hi,
I have trawled through several documents and tried umpteen different configs, all to no avail. I have a PXE boot client trying to access a boot file via TFTP from a couple of TFTP servers on the same VLAN/subnet. For HA purposes I want to load balance the two TFTP servers.

I have read the doco by Ivan Kovacevic amongst many others but as my clients and servers are on the same subnet, the config doesnt work.
Can anybody point me in the right direction please. The devices are ACE 4710 running A3(2.3).
Thanks

Try using the following configuration:
Note: Please make sure to configure also a udp probe to probe udp port 69, in case the application is down.
You need to configure a management policy on the interface when using a UDP probe.
That is because, when port 69 on the server will be unreachable, the server will send an ICMP unreachable.
ACE will consider a udp probe as "failed" only when it sees ICMP unreachable.
Without a management policy-map, the ICMP unreachable message will be dropped.
Also, add an ICMP probe to the rserver because udp probe will not be enough when the physical interface will be down.
That is because UDP is a connection-less protocol. To consider a UDP probe successfull, ACE need to see NO answer from the server in respose to the probe.
The ACE will not see any answer from the server when the interface is down and thus, will consider the probe as "sucessful".
With ICMP probe attached to the rserver, you also test the reachability of the server and not only the UDP port.
Here is the configuration (of course, you can chage the names of the of the objects to the name you are using if you want) :
access-list ALL line 10 extended permit ip any any
probe udp TFTP

URGENT !!! Two physical network interface with two completely different subnets - No bridges - cannot connect both

This is my urgent problem:
I have a physical machine with two physical network interfaces. I have a VMWARE player installed and a virtual machine that must use both cards on two different subnets, one directly public on the router and one intranet inside the company.
How can I just tell one net card to go on that sub and the other on the public sub ? Going crazy. Please help.
Thanks,
P.

Using VMware Player Virtual Network Editor, create a additional bridged VMnet and bind each bridged VMnet to a different physical network adapter... on virtual machine, create a virtual network adapter to each subnet, and bind each virtual network adapter to a different bridged VMnet.
For additional help with virtual network editor, check this KB: VMware KB: Using the Virtual Network Editor in VMware Workstation

Troubleshoot the network as that is likely what is causing the issue.
Also, temporarily disable the firewall on the Mac and disable IPV6 on the computer.

I have two networks one each in two cities. Both are named the same but require different passwords. I am at my second location and cannot connect to this wifi network. How do I delet one network so I can connect to my second network?

Just go to the wireless network preferences and empty out all the stored wireless networks.. then scan and connect to the local wireless.
Select them and tap the - button below it.
Once they are emptied out.. it might be good to reboot the computer with the remember networks unchecked.
Start with a clean slate.

Airport Extreme
You should plan to connect one AirPort Extreme to the modem and the second AirPort Extreme to the first. The first Extreme will connect to the modem using an Ethernet cable. The second Extreme can connect to the first also using an Ethernet cable, or it can connect using wireless only.

2 network connections at the same time

I have 2 network connections at the same time. One for network shares and one for internet. How can I decide which connection should be used for which service?

David684,
Thanks for posting all of this. I have a similar network question with a very similar setup that I am using with two interfaces. However, I am much less comfortable with the command line than you appear to be (although comfortable enough to crib little tweaks from the web and run them).
The real difference is the resources I'm after and it seems like more of a problem. In my case, I'm running my home wireless network and can connect at decent speeds, but I happen to live right across from campus where I am attending grad school and I'm picking up the school wifi network. Having direct access to this network, among other things, allows me to access library research journals and databases from home without constantly needing to authenticate. But it isn't nearly enough to accomodate all of my network needs. The key difference, then, is the fact that these come in the form of websites. But I want to access only library stuff over that we-fi connection and do everything else from the LAN. I use an app called papers for research, which has a built in web browser to allow me to pull up articles and then save them. Would that help me by allowing me to have just that program use wi-fi? I am not sure if the app is using an embedded safari session or it's own home-rolled browser, or how to check in the first place (OR if that makes a difference as far as being able to route the app's traffic to that interface). Also, with all of that said, how could I find out the subnets over which to route this if what I'm going after is a far less tangible resource than an SMB share? I am guessing I need a different method or that none exist?
Thanks

I have the new ipad retina however i connect it to the wifi at work the signal comes and goes, especially as soon as i use an app that requires wifi, my iphone 4s is connected to the same network with no such problems, why is my ipad giving me these probl

I have had my ipad retina for two and a half weeks but since the week end every time i connect to the wifi network it joins then disapears as soon as i open safari for example or just disappears at intermittent intervals....i have my iphone 4s connected to the same wifi network with no such problems.
I have tried resetting the network settings to no avail
Does anyone have any suggestions?
Many thanks in advanced.

My Ipad 2 cant find my HP3050A j661b airprint printer although the printer is connected to the same wireless network and software updates are current on all and my other laptops also work properly with this printer.further more it used to work with my IPAD2 before when I used the old wireless router but now I changed it to HAUWEI HG231f but I set everything in the same way it was. Thanks in advance.

When you change to the new router, did you re-run the CD to re-set the new SSID and password to the printer.
Otherwise your iPad will not be able "talk" to your printer.

Currently I have two iPads connected to the same Apple ID and one connected to Game Center. I want to connect the second iPad to Game Center so that I do not lose my progress on apps like Clash of Clans.

Currently I have two iPads connected to the same apple iPad. One is connected to game center(iPad air) one the other(iPad 2) is not connected to Game Center. How can I connect the iPad 2 Clash of Clan progress to game center when I already have another clash from iPad air connected?

You cannot transfer content between two accounts. The sooner you make the conversion, the better. Just pick the new one and start using it(buying music etc).
*A lot of people open new accounts when their email changes or they have a new email. You can just access your apple id account and change the primary email that you use to log in along with other details.

I have 2 iPhones - one for personal use and one for work. They are currently connected with the same Apple ID. I would like to separate the two accounts. Does anybody know how to do this?

Just create a new AppleID for your work.
As Allan suggested, items purchased on one iTunes account cannot be moved to the other account.
However, you can put items purchased on on account onto the other iPhone.

TS2235 Hi, how can I print from my IPAD to my wireless HP 6520 printer. I have a wireless network and my IPAD and wireless printer are connected to the same network. But when I send a job, I get the "no air printer found" message.

My windows firewall is disabled (protected by Comcast's Norton program) so that should not be a problem. Should I down load Bonjour?

Hello Bleedingblue65
Check out the section highlighted below to troubleshoot your issues printing through AirPrint.
AirPrint Basics
http://support.apple.com/kb/ht4356
If you are unable to print, or if you see the message "No AirPrint Printers Found"
Verify that the printer:
Has power and is turned on. If it has power, turn the printer off and then on again to see if that resolves the issue.
Is connected to the same Wi-Fi network as the iOS device.
Has the latest firmware version installed.
Has paper with enough ink or toner installed.
Is free of any errors displayed on the printer's control panel.
If necessary, consult the printer documentation or contact the printer vendor for help with the above steps.
Notes:
AirPrint printers connected to the USB port of the Apple AirPort Base Station or Time Capsules are not supported with AirPrint.
Some Wi-Fi AirPrint printers can take several minutes to join a Wi-Fi network after being turned on. Ensure that the AirPrint printer is connected to the Wi-Fi network before attempting to print.
