New Network Configuration Question

• VLAN again added, problems detected on guests during the detection of new network configuration

  Hi all

  I started facing a strange problem trying to use a new VLAN configured in my vCenter environment...

  Basically, my system 'fight' to identify the new network label (VLAN) configured, leaving systems disconnected from the local network.

  This condition disappears only when I change the VM touched, assign a label of different network (VLAN), apply the changes and restart the process by configuring the new VLAN return.

  We will use an example to explain better:

  • I have a named Windows Server/Workstation VM: VM1
  • I have 2 VLANS configured in vCenter: VLAN50 and VLAN70

  VM1 is sitting on the VLAN50 and has the static IP address configured.

  I start the migration of the machine to a VLAN different, by editing the network settings of the operating system (IP, MASK, GW, DNS entries...) and replace the label of VM1 VLAN70 network.

  At this point, the machine NIC shows as if it could not connect to what in the network, although it is configured accordingly in order to communicate in the new subnet.

  I have change the VM again and change the label of a network VLAN different from VLAN70, click OK. Immediately, I change VM settings to assign in return the VLAN70.

  After that, the operating system recognizes the network successfully and starts working as expected...

  All of my virtual machines use VMXNET3 adapter and my version of vCenter is v5.5 build #2646482

  No idea what might happen?

  Concerning

  We found the problem...

  It was not associated with VMware, but a network configuration problem: (ESXi connected to two switches, one of them with the VLAN configured correctly and the other does not...).

  Thanks for the help

• Network configuration question

  I'm one of our 5.5 hosts replace with new material and want to make sure that I get the right networking. We have unit vcenter and a HA cluster with shared on an EQ San storage and complete double switches for redundancy. My old hosts have 2 quad port NIC, so configure each vswitch with double vmnic for a total redundancy was easy - I split each pair on the physical network interface cards. If one of the physical network cards is dead, I was still all my connections.

  The new host has 1 quad port nic and dual 2 network cards to port. Network interface cards double port match and have tcp offload capabilities, but the quad port does not. I want to use the dual port 2 for my iscsi and vmotion, so that leaves the quad port for my public connections. What happens if the public NIC dies, especially if they vcenter on this host? I know that all the virtual machines will still work, but will they automatically vmotion to other hosts if only the public network fails?

  Thank you.

  NIC failures are very rare. So, I would place too much emphasis on this scenario.

  Is the answer to your question, it depends. HA has a configuration option called isolation response of the host, who controls what happens when the host loses connectivity management. By default, it is configured to leave it powered on. You can change it to Shut Down, which makes sense in your scenario, as the loss of connectivity management means the loss of connectivity to the virtual machine as well. And in this way when management network goes down all your virtual machines is gracefully closed and restarted on another host.

• For the installation of new network configuration

  I have a few new pieces of equipment to start of my virtual machine configuration. However, I'm not entirely sure of what would be the most effective way to implement the side network and side EQL, then I would like some feed back.

  The kit:

  • 1 x Cisco 2960 24 port (management / VMotion)

  • 2 x Power Connect 5424 24 port (net SAN)

  • 1 x EQ6000xv 300 GB * 16 discs for 4.8 TB Raw (SAN with 4 ports/controller)

  • 1 x R610 (broadcom 4) (vCenter server)

  • 2 x R710 (broadcom 4 Nic TOE + port 1000PT Intel 2 additional on each server for natachasery/Server 6 total) (ESX / I have knots)

  Network:

  Currently I have a certain VLAN ongoing enforcement, and because of some complications, looks like I won't get a subnet that is dedicated to the SAN (still pending).

  Virtual machines will never access 5VLANs (including the Management VLAN I have a virtualized network monitoring app too).

  I saw a white paper about it there but I can't find it now.

  SAN:

  Regarding the EQL, I think of the following:

  1. 1RAID 0 (I know it's plenty of space to go, but it would be better? Dell saw recommend 50)

  2. 1 flight approximately 500 GB to store all the OS vmdk (a number will be unique discs because they do not really data and many have less than 1 GB)

  3. 1 flight, size 1 TB for mapping directly to a VM file server using the MS iSCSI initiators

  4. For the rest, I could leave it as what and the provision necessary.

  5. I also intend to provision thin all the VMDK and also the volume so

  What needs to be run once to the top:

  • Two announcements (Win2K3), which will also be the file server.

  • 3 guests in low use of WinXP

  • 2 WinXP with DBs (each running on offices of single disk with P4 CPU of 2 G)

  • 1 WinXP host already on a DL380G3 with ESXi... this one is probably of the same caliber as the previous ones

  What is to come:

  • Installing SharePoint Services possible (more than 2 Win 2K 3 or guests with a SQL running Win2k8)

  • ISA Server

  I would greatly appreciate any comments.

  You are welcome.

  If you find useful information, consider giving points to 'correct' or 'useful '.

• Cisco ACS SE "set ip" error: could not set up new NETWORK card configuration.

  Hello

  I get the error "error: could not set up new NETWORK card configuration." When I try to set the IP ACS SE.

  When I called into the device image and tried to do an initial installation, the IP to not hold after the restart and went back to the default value.

  I went by NetPro and apparently it is a common problem. One person it is solved re-imaging unit, but who has not worked for me.

  Someone there with a solid solution? I use NIC 1 FYI.

• Networking question in VMware Workstation / nested ESXi network configuration problem

  Hi guys,.

  I am trying to set up a virtual lab, I setup a domain, a vcenter server and up to 1 ESXi host controller.

  I am really struggling with the network aspect in establishing a vmnic for storing shared, please see the attached screenshots and a few questions:

  1. Is a vmnic a real network map? or vmnic correspond to "network adapters" that you put in place since the setting of your virtual machine?

  I followed a tutorial and implement 3 NICs on the ESXi host, in Bridge mode, I tried this in my configuration of vmworkstation and I lose the connection to my server vcenter to the ESXi host.

  See screenshot attached to how I configured my ESXi host, screenshot is called 'screenshot2esxihost network', I run got each of the maps defined on NAT network.

  

  See also the screenshot of how I have my configuration of network settings in my VMWare Workstation, screenshot is called "screenshot1. the tutorial does not show how it has its editor of the virtual network configuration, but it puts its ESXi host NICs in BRIDGED mode, and I'm guessing that you can set this time within the virtual network adapter. If someone could tell me what changes should I make in there and on the network cards in my ESXi host, which would be really useful.

  

  My domain controller, server ESXi hosts and vcenter are currently on the 192.168.86 range, which currently stood at NAT

  See also a screenshot from the vsphere client - I don't see a vmnic "vmnic0", my goal is to be able to add a "vmnic2" for a separate storage network.

  

  any help would be received with gratitude, I VCP510 review at the end of the month and really hope to be able to get my lab setup as soon as possible.

  The vmnic is the rising 'physical' of an ESXi host. So with the 3 network cards that you configured for the host in VMware Workstation you will see under "Network adapters" and you can use them to vSwitches in the section "network".

• Old Time Capsule join new network

  I plan to upgrade my home network by buying a new Airport Extreme with 802.11ac as main router and let old TimeCapsule join the new network.

  

  I would like to know it's installation work? Let's all backup Time Machine of my MIC works well? Thank you.

  Unlike the AirPort Express, you cannot configure the old Time Capsule to join an existing network to use as a wireless Ethernet bridge. Instead, it will have to be configured to extend the network of the new extreme wireless if you want that connection between them in order to be wireless. This would still allow the Ethernet ports of the TC for your MacBook Pro to use for connectivity.

• network linking questions

  I just bought a new Capsule 2 G and I tried about 30 x to set up and connect to my network without result.  Why is it so * difficult? I should just be able to connect this thing in and extend my existing network.  However, every time, no matter what, it will not apply, and only wants to create a new network.  Help, please!

  Please specify if you want the time Capsule to "extend" your existing network by connecting to your main router using a wired wired Ethernet, Permanent

  or

  If you want the time Capsule to "extend" your existing network by connecting through a Wi - Fi connection.

  IF... you want to the time Capsule to connect to your existing network using a wireless connection, your 'main' router is also an Apple product?

  or

  Your 'main' router is a product of part 3?

  Should we guess you use a Mac with a current or recent operating system installed to configure the time Capsule?

• Unable to create the new network former TC

  Hello

  So I have the current generation of TC acting as a router as well as a HDD on my old to wide wireless broadband. I experienced some problems with connectivity recently (where my MacAir shows that I am connected to the internet, but no matter what site I try to access everything simply does not load and ends up with a progression of Ribbon on the address bar of Safari-turn off and turn on the power back constantly solves the problem), but this is not what I am asking today. Recently, I had the new optical fiber internet for my house and got a new modem and everything has been installed. Only one of the four ports in the modem seems to work, but at least it works. The D-link router that came with it works fine, but I want to use my TC as the router instead. However, whenever I connect the TC on the working port, I am unable to connect. Airport utility, the lights of TC in green but 'Internet' is yellow, i.e. does not work correctly. It should be a problem with the TC because the D-link router works on the same port and connection ethernet via a thunderbolt on the same port adapter works perfectly fine as well.

  Is this a problem with the old settings on my TC being incompatible with the new network? Please advise, thank you very much!

  There are at least 2 different issues at stake here and possibly 3.

  A question is that whenever you change the modem or the router that connects the TC, or your provider of Internet services, the TC must be reset back to settings by default, and then set it up again to work properly with the new product and the new service.

  You don't mention how old your 'old' Time Capsule can be, but 3 years is on the average life of the time Capsule, if anything more than 3 years will be suspicious where reliable operation.

  The third possible cause is that only a single port of your modem/router works when the four should work. If this is a real problem here, we can't say, but you have to wonder a little about the reliability of a product that doesn't seem to work properly

• P1102w - new router, the new network not printing

  I had the 1102w all set up and running on my network printing from 4 different computers. This morning, I changed a combination of westell/Belkin modem/router for a new modem router from verizon. I created a new network with wpa2 security. I got all the computers in place but the printer does not print - printer dialog reported an error in printing (no error message, just with the special printer, an error has been reported). The blue light continues to blink. I thought that it was because the printer was trying to talk with the new modem but did not have the wpa key. It also meant that I could not go in the printer from one of the computers to change the wireless settings. I tried to install it on my Surface via the USB port, but then I didn't know what to do. I tried the reboot and reset everything. I even disabled the security on the network then it would not require a password. But still, the blue LED flashes quickly and then turns off. The configuration page shows all 0.0.0.0 for different addresses even theough the computer is always looking on the IP that the printer used to keep.

  Help, please! How can I get the printer to reconnect to my network?

  Hello

  To connect the printer to your new wireless router, you must use the interface for installing software as follows:

  1. Download and run the latest version of the software below. escape in the installation, and then close the configuration screen that is launched:
     http://h10025.www1.HP.com/ewfrf/wc/softwareDownloadIndex?softwareitem=bi-80329-8&cc=us&DLC=en&LC=en&OS=4132&product=4110396&sw_lang=
  2. Navigate to C:\LJP1100_P1560_P1600_Full_Solution and run the HpSetup.exe file.
  3. Select easy install, then the Series HP Laserjet Professional P1100w.
  4. Select Configure to print over wireless network.
  5. Click next and follow the instructions on the screen.
     Note: the installation invites you to temporarily connect a USB cable to put the settings back wireless to the printer, be sure to unplug the unit once configuration is complete and the installation invites you to do so.

  Once configuration is complete, don't forget to restart the other PC and ensure that everything is running.

  original title: grafting the internet

  Hi Maureen,

  That your router has security enabled protection?  My guess is it doesn't and it's the way that person uses your wireless connection (like someone to visit with a laptop you could if you configure).

  As a general rule, access to the router is by typing http://192.168.1.1 (or whatever your gateway address) in the address bar of your browser and you will be able to bring up the router configuration settings.  He'll probably want a username and password.  Sorry, I can't help you there because I have no idea what it could be.  Try admin/admin or admin/password or administrator/administrator or administrator/password or admin and no password or admin and no password (the classic default settings).  Your ISP or service of technical assistance of the manufacturer of the router may be able to help put this in place.  After that, how configure security entirely depends on the ISP, the router, the type of operating system you have, the type of internet connection you have and a number of other factors that I have no way to know, even if you told me that information.

  In fact, to see if this applies even, go to the Network Center and sharing, and click on manage wireless connections.  Select and double click on your network.  Click the Security tab and see if it is configured with the entries in the drop boxes first two points in the key with a password applies.  If it does not exist, then there is no security on your wireless router.  If there is, then your network is secure without doubt.

  When you see the active connection, click on start / all programs / accessories / and double click on Control Panel.  Type IPCONFIG/all and see if you can identify this other connection of the computer.  It should provide more information about it for the purpose of identification.

  If your router is not secure, you must fix and this should solve the problem.  If your router is secure, you should change the password/key of the router to see if that solves the problem (and then you will need to change the key to all your wireless computers and devices to match the new).  If it still does not work, then come back and we will come with some other ideas (assuming that the manufacturer of access provider or router cannot help you with this).

  I hope this helps.

  Good luck!

• New router = the name of the new network, how can I get my wireless Dell 966 printer to recognize the new network?

  I got everything set up on my new network, but have not been able to set up my Dell 966 Wireless printer.  It worked fine with the old router.  The name of the network on the printer is still my old network name, not a new one.  I can't find the printer when I search for wireless.  Printer sharing is on, and the port is set for the printer.  I have reset the desktop computer and the printer.  I checked and double checked all connections.     9

  + The wireless set up the menu of the printer is the former name of network, and I don't know how to put the new name in.  It is grayed out so I can't select it.  I don't find a way to do it either from the office.  Any suggestions?

  Hello

  Configure the printer with a static IP address to connect directly to the router (read the manual).

  Next, configure the computers on the network to print to the static IP address.

  The network name or the name of the router would be important.
