• Network configuration for ISCSI and VMotion

  Hello

  I have an ESX host configured with the iSCSI storage and am currently working on the best way to affect my NIC I a four VMK vSwitch and two nic

  http://communities.VMware.com/message/1428385#1428385

  I also have an additional switch for VMotion.

  -Service 2 console

  vmnic6 and vmnic7 are both on the San.

  After adding the new VMkernel and activation of vmotion, I was wondering why this has not shown as an additional path to the storage (I want to know if this is another question). Then I ran "esxcli swiscsi nic list d vmhba33" and of course, only the first four VMK was listed.

  Why the new VMKernel is not automatically linked to vmhba33?

  It would be a bad idea?

  See you soon

  Just to play devil's advocate, why shouldn't be VMotion and SAN traffic on the same link though?

  the iSCSI traffic MUST have a low latency and no mistake.

  VMotion can create advanced that could generate problems in iSCSI traffic.

  No idea why it does not automatically bind well?

  Can you vmkping each IPs Eql?

  You have to add each interface vmkernel of initiator iSCSI, with a command like this?

  esxcli swiscsi nic add - n vmk0 d vmhba34

• WSD port for printers and TCP/IP ports monitor, what is the difference?

  There are a lot of discussions on IP etc. addresses for printer problems. There is no mention of a new feature for the port for printers, WSD port for plug-and-play printers, I assume that the IP addresses have no importance with WSD, my printer is vaguely configured for the WSD port and TCP/IP port, can someone please expain

  Here is a description I found

  The WSD Port Monitor is a new printer port monitor in Windows Vista and Windows Server 2008.  This port monitor supports printing on network devices that are designed to include Web Services for devices (WSD) technology.  Services Web for devices allows devices connected to the IP-based network announce their functionality and to provide these services to customers using the Web Services Protocol.  Clients and devices WSD communicate on the network using a series of SOAP (Simple Object Access Protocol) messages on UDP and HTTP (S).  WSD for devices offers a plug-and-play network experience that is similar to the installation of a USB device.  Services Web for devices also defines a security profile that can be extended to provide additional protection and authentication by using certificates based on the device.

  WSD is not a port, but a port monitor.  A port monitor looks at information from the TCP/IP port and makes routing or changes based on what happens in the port.

  This link has some in the description of the depth of the WSD port monitor:

  http://blogs.technet.com/b/askperf/archive/2008/02/11/WS2008-the-WSD-port-monitor.aspx

  Back to the comparison of the IP address as a P.O. box.  Once the letter arrives in the POST box, someone needs to come empty the box or letters are going no where.

  When the data comes in the TCP/IP port a port monitor is where I look for that to happen.  The WSD port monitor would take over this function from the standard TCP/IP port monitor.

• Change the default ports for http and https

  Hello

  I'm trying to change the default ports for http and https

  I have a 506th PIX (which does NOT of NAT)

  I have the following: -.

  static (inside, outside) tcp 192.168.10.2 601 192.168.10.2 http netmask 255.255.255.255 0 0

  Access-group acl in interface outside

  where 601 and 602 are the http port and https to be redirect to respectively.

  I changed the webserver accordingly

  I get the error message

  "No group of translation not found for tcp src outside:189.x.x.x/50232 dst inside:192.x.x.x/80" (trying to access port 80)

  "I also have ' fixup protocol http 601.

  I had access to the internal and external web server before attempting to change the default ports

  Any ideas where I'm wrong?

  See you soon.

  I apologise for not thinking correctly.

  the static method must be:

  static (inside, outside) tcp 192.168.10.2 80 192.168.10.2 601 netmask 255.255.255.255 0 0

• Can we have different default gateway for MGMT and vMotion?

  Hello

  We run vSphere 5.1 update 3 Enterprise Edition. VLAN is implemented in our site recently.

  Network administrator assigns 3 VLAN to MGMT and vMotion VLAN10.  It also gives me different for these 2 DG VLAN (there is another local network VIRTUAL for VM).

  When I set up the IP address of vMotion, can I change to a different DG of the vSwitch MGMT?

  Thank you

  vSphere 5.1, no, you can't.

  vSphere 6, yes you can, here vmware now gave us separate stack TCP/IP for vMotion and contributes to the vCenter vMotion cross too.

• In FF Extensions's why uninstall shaded for Realplayer and Skype

  When I try to uninstall the Plugin Realplayer browser Record and the Skype Extension for FF, the uninstall is greyed out - can I disable only.
  Why is this? I would rather uninstall them completely.

  If uninstall is dimmed, then it means that the extension is installed in the world and not to hand and under the control of Firefox. You must look in the preferences (options) of the program that installed the extension to see if you can uninstall it.

  You can disable/remove the extension "Plugin RealPlayer browser Record" in the preferences of RealPlayer (RealPlayer: Tools > Preferences > recording and download)

• Why the update for Premiere and After Effects is not available in my CC app? I NEED it!

  Hello

  I hope someone can help me with this even, Yes, very frustrating problem. I've recently updated 2015 CC, simply because I had to because my colleagues did. My creative cloud application however does not accept and shows that older versions of the CC apps. I currently run 13.5.0.347 AE and PR 9.0.0 and according to the CC app no update is available. I run OSX Yosemite and tried to reinstall the CC application.

  Is someone can you please tell me why I can not update? I need this because the problems of rendering in AE are so frustrating (than F * $# * ^ * rendering of the space bar and not being able to cancel kills me). And the deadline does not help...

  Thanks in advance!

  Maybe it's that your system does not meet requirements for the latest software.  You can check the system requirements through the page linked below.

• Why is password for SYS and SYSTEM different

  I use 10g Express
  During the installation I created the password and I use it as a password with SYS, but it does not work with the SYSTEM

  Thank you.

  Hello

  The SYS and SYSTEM password are asked during the database creation process.

  May be that a different password has been set.

  Anyway, as you know the password for SYS, you can change the password for the SYSTEM with the following statement:

• Audio input on mac (MacBook Pro (retina, 13 inch, mid-2014) which has a single audio port for headphones and number of PORT of ENTRY.

  How to do on my MacBook Pro (retina, 13 inch, mid-2014), which has only a headphone audio input port? Do Garageband, or Preferences/audio, or Audioand MIDI or what?

  Connect an audio interface to a USB port to have an audio input, or insert a divider entry in the headphone port. You need additional hardware to have an audio input.

• VMKernel port group

  Here is the configuration of the network of one of our hosts ESX 4.1:

  (1) the virtual computer network

  (2) Service with 1 IP console

  (3) VMKernel with 1 IP for vMotion and iSCSI, called as VMKernel_iSCI

  I can see there are 4 NICs attached to this host.

  Now, I just know, that same using iSCSI and vMotion VMKernel is not a good practice.

  question 1

  So I would like to know how is the mapping of the ESX host's network. Is this;

  1 NETWORK card = 1 VM Network

  1 NETWORK card = 1 Service Console

  1 card NETWORK = 1 which is currently used for iscsi and vmotion VMKernel port group

  In a standard switch, there are 2 network cards configured.

  2nd question

  I want to delete 1 port VMKernal vmotion (VMKernel_iSCI) and create a dedicated for vmotion.

  I know that I have will require another IP address, but what of NIC, it will be;

  1 NETWORK card = VMKernel_iSCSI

  1 NETWORK card = VMKernel_vMotion

  Please explain.

  Thank you

  Mihir

  From a pure technical point of view, it will work, as long as your network is configured properly (i.e. taking advantage of VLAN and the separate subnets on management, vMotion and iSCSI). However, I am worried about the bandwidth and quarrels with such a configuration.

  BTW. except if you've already seen it, I would recommend that you take a look at http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf

• public network for virtual machines, private storage and the service console?

  Hello

  So far I had a pretty small facility with 2 servers with 4 physical network adapters each running ESX 3.5, a small box of EqualLogic SAN to shared storage and a few virtual machines on our network of regular reinforcement, routed, not on a private.   The network config was really simple.  I just put everything on real IP addresses on our network of building.

  Now I want to move the SAN and the traffic on a private service console network, but I don't know how to do this.

  Right now I use 2 NETWORK cards on each server:

  vmnic0 is configured on vSwitch0 and has the network of the VM on it that all my use of VMS to talk to the outside world, and it also has the Service Console that uses Virtual Center and I use ssh to it.

  vmnic1 is configured on vSwitch1 and a VMKernel Port and also a Service Console Port for iSCSI Software to talk to my SAN.  (never been clear on why both are needed to talk to the SAN, but doctors say they are)

  My plan is to set up a vSwitch2 and bind it to vmnic2 and implemented a VMKernel Port and the Service Console Port for software iSCSI on the 10.x.x.x network, set up my new (larger) SAN box on the 10.x.x.x network and simply use Storage vMotion to move virtual machines to the new storage space.  As soon as I did this, I would like to not use the Service Console on vSwitch2 and not a Console Service at all on vSwitch0.  Is it possible to delete the one on vSwitch0 and just use a new vSwitch2 for Virtual Center and ssh access?

  So my proposed configuration would be:

  vSwitch0: VM network only, used by the VM guests for oriented public access network, no construction of Network Service Console, linked to vmnic0

  vSwitch1: superfluous once I do storage vMotion of everything on my old SAN, will eventually remove and pair vmnic 1 with vmnic0, linked to vmnic1

  vSwitch2: VMKernel and Service Console on the network 10.x.x.x, used to access the new SAN, used by Virtual Center to access the ESX, used to SSH in to ESX on private network, associated vmnic2

  If it works?

  Thank you.

  Hello

  VMkernel ports cannot live on the same subnet. So if you have 3 vmkernel ports say: vMotion, iSCSI and NFS. You really need 3 subnets. 1 for each vmkernel port.

  Otherwise how does he know all send properly?

• Dedicated switches for ISCSI switches dilemma...

  Hello

  I bought two dedicated switches (I thought they were in any case) for ISCSI traffic that I had planned on just my ISCSI traffic from 3 dedicated ESX host connection.

  Now the network team is said it opened enough ports on switches from my heart for the IP traffic such as vmotion, machine VM... etc.

  How can I use the new switches that I bought for ISCSI traffic only, to include also the IP traffic, but everything in remaining secure? I would do that with the VLAN?

  If so, how would I go on this subject?

  I would use VLAN for that. Trunk at the bottom of the ESX host and dedicate and label your ports vmkernel or groups of ports.

  Example:

  vSwitch0 with -

  iSCSI: vlan 5

  VM traffic: vlan 6

  VMotion: vlan 7

  Configuration:

  VMkernel port ISCSI0, vmk1 tagged vlan 5

  Port group VM-traffic, the tag vlan 6

  VMkernel por vMotion0, vmk2 the tag vlan 7

  Regarding safety, it depends on your needs. You can always leave the VLAN iSCSI and vmotion again according to the requirements of connectivity to other systems.

  Something like that can work?

• 3i Embedded and vMotion

  How do people set up their Embedded 3i for NIC redundancy servers in a system of NETWORK 6 card?

  In the past, on traditional ESX I have configured as follows for not to consume more than half the NIC for management and VMotion.

  • Assign 2 network cards to vSwitch 0 (or Vswif0 in ESX), for arguments sake Let's say vmnic0 and vmnic3

  • Have 2 groups of VMKernel ports on vSwitch0, one for the service console (management in 3i connection) for VMotion.

  • I would then bypass the switch by default to be as follows:

  • Vmnic0 is the active NIC to the service console, vmnic3 is set to failover only

  • Vmnic3 is active for Vmotion NIC, vmnic0 is set to failover only

  This means that 2 network cards using the interface of the console/service management and Vmotion use their own NIC unless there is a problem with the NETWORK card, in which they would share a NETWORK card as long as the problem persists.

  To do it in a card system NETWORK 6 then leaves 4 network cards available for traffic of comments.

  However, when I tried to do in 3i I HAD to put in a gateway for the interface of Vmotion or HA would fail to set up with various errors such as cannot solve the other guests or is unable to ping address of default isolation.

  Now, while things work, I had to set the gateway of Vmotion VMKernel default gateway, if it appears as the default gateway for the management interface as well which is a little disconcerting.

  I did some research and I found references to the use of das.allowNetworkx and das. AllowVmotionNetworks to control traffic HA, but I can't find anything to say if it will affect my current number.

  It has been suggested to create switches separated for the service console and Vmotion traffic, but to ensure the resilience it will take 4 of my 6 NICs, only leaving 2 for customer traffic, which is a little limited.

  Welcome to the VMTN Forums,

  Could you try the following:

  The das value. AllowVmotionNetworks to false. Add your default gateway to your management network which can be ping from the console. It should work?

• Migrate to vDS for iSCSI Software

  So I'm going through the vDS migration guide, but I'm still a little fuzzy on how I need to migrate my VMKernel ports software iSCSI. Here is my setup...

  I have 4 hosting a test cluster. Two network ports are dedicated on each host for vSwitch1 which has a VMKernel port with an IP address in the 10.5.33.

  How can I disconnect from my software iSCSI initiator or migrate the IP address of a vSS to a vDS without a cause of a conflict?

  While add you ESX host service VDS, there is an option to add the console service & VMkernel iSCSI to the vDS. If you already add this particular vDS host, remove first the host of vDS.
