• How change the font and size of the textarea element

  Hello - I have several pages of form who have for the most part, the text elements. However, I do
  the few pieces of textarea, and are by default the font and size of these
  something different than the text elements.
  
  How can I change the font and the size of the textarea, such a preference items
  how it will apply to all textarea elements in my application?
  
  (And to take a step back, where can I find definitions of police and the size of these)
  elements? I guess it's in CSS (?), but don't really know what to look for.)
  
  Thank you
  Carol

  This type of problem is usually due to Re: Textarea font different from that of the text fields, which will almost always cause Re: Multiselect list police-family.

  You use one of these themes? If so who?

• How change the deformation and transform the 'copies' individually?

  I need to create a circle of 13 stars in symmetric mode and with one of the stars being the upper dead point vertically. I was able to do this by creating a unique Star, will "distort & transformation" in the menu effects, creating copies of 12 (12 + 1 gives me the 13 I need) and adjust the values of the tool to get what I need.

  The problem I have is that only the master original stars can be changed. Is there a way now modify each of these 13 stars individually? I have spent an hour trying to find an answer to this but couldn't find a thing. It seems that there is a simple solution. I am wanting to do this is because I need to cut out ALL the 13 stars surrounding circular using the 'less before' option in the pathfinder tool palette. When I use "before", it subtracts just the original parent star and not the other 12?

  While not as important, I have another question... If anyone knows how to increase the size of the stars themselves (after the effect "skew / transform", that would be great.) Using the scale tool will increase the size of the global circle in stars, but not the size stars while keeping the same circular diameter. Does make sense?

  Any help would be greatly appreciated. Thanks for your time.

  All select and use Expand or break down the appearance (which ever exists) in the menu object. After doing above, Direct select the stars and use Transform > transform each scale of each from the center of the star.

• Nexus 1000v, UCS, and Microsoft NETWORK load balancing

  Hi all

  I have a client that implements a new Exchange 2010 environment. They have an obligation to configure load balancing for Client Access servers. The environment consists of VMware vShpere running on top of Cisco UCS blades with the Nexus 1000v dvSwitch.

  Everything I've read so far indicates that I must do the following:

  1 configure MS in Multicast mode load balancing (by selecting the IGMP protocol option).

  2. create a static ARP entry for the address of virtual cluster on the router for the subnet of the server.

  3. (maybe) configure a static MAC table entry on the router for the subnet of the server.

  3. (maybe) to disable the IGMP snooping on the VLAN appropriate in the Nexus 1000v.

  My questions are:

  1. any person running successfully a similar configuration?

  2 are there missing steps in the list above, or I shouldn't do?

  3. If I am disabling the snooping IGMP on the Nexus 1000v should I also disable it on the fabric of UCS interconnections and router?

  Thanks a lot for your time,.

  Aaron

  Aaron,

  The steps above you are correct, you need steps 1-4 to operate correctly.  Normally people will create a VLAN separate to their interfaces NLB/subnet, to prevent floods mcast uncessisary frameworks within the network.

  To answer your questions

  (1) I saw multiple clients run this configuration

  (2) the steps you are correct

  (3) you can't toggle the on UCS IGMP snooping.  It is enabled by default and not a configurable option.  There is no need to change anything within the UCS regarding MS NLB with the above procedure.  FYI - the ability to disable/enable the snooping IGMP on UCS is scheduled for a next version 2.1.

  
  
  This is the correct method untill the time we have the option of configuring static multicast mac entries on
  
  the Nexus 1000v.  If this is a feature you'd like, please open a TAC case and request for bug CSCtb93725 to be linked to your SR.
  
  This will give more "push" to our develpment team to prioritize this request.
  Hopefully some other customers can share their experience.

• Change the maximum number of ports on Nexus 1000v vDS online with no distribution?

  Hello

  Change the maximum number of ports on Nexus 1000v vDS online with no distribution?

  
  

  I'm sure that's what the link

  VMware KB: Increase in the maximum number of vNetwork Distributed Switch (vDS) ports in vSphere 4.x

  not to say that

  I have 5.1 ESXi and vcenter

  Thank you
  Saami

  There is no downtime when you change quantity "vmware max-ports" a port profile. It can be done during production.

  You can also create a new profile of port with a test of the virtual machine and change the "vmware max-ports' If you want warm and ferrets.

• ESXi 5 and Nexus 1000v

  Hello

  I have an ESXi 5 but only NIC I am migrating the VSS for Nexus 1000v. I installed Nexus VEM correctly and do primary and secondary, VSMs configured uplink port groups all according to the guides from Cisco. When I try to add a host under the link, I have first to migrate the vnic0 for the Group of appropriate uplink ports and it then asks me to migrate the management port (I think it is vmk0) so if I create a group of ports on Nexus to migrate a management port or do not migrate at all I always lose connectivity to ESXi.

  Can someone please share the configs of the Nexus 1000v and how to migrate properly vnic0 and vmk0 (with a single physical NETWORK adapter) so that I do not lose connectivity?

  Thanks in advacne.

  Remi

  control is vlan 152 and package is 153.

  You can make same vlan. We have supported using the same vlan for the control and the package for several years now.

• Nexus 1000v and vSwitch best practices

  I am working on the design of our vDS Nexus 1000v for use on HP BL490 G6 servers. 8 natachasery is allocated as follows:

  vmnic0, 1: management of ESXi, VSM-CTRL-PKT, VSM - MGT

  vmnic2, 3: vMotion

  vmnic4, 5: iSCSI, FT, Clustering heartbeats

  vmnic6, 7: data server and Client VM traffic

  Should I migrate all the natachasery to 1000v vDS, or should I let vmnic 0.1 on a regular vSwitch and others migrate to the vDS? If I migrate all the natachasery at the very least I would designate vmnic 0.1 as system so that traffic could elapse until the MSM could be reached. My inclination is to migrate all the natachasery, but I've seen elsewhere on comments in forums that the VSM associated networks and, possibly, the console ESX (i) are better let off of the vDS.

  Thoughts?

  Here is a best practice-how-to guide specific to 1000v & VC HP might be useful.

  See you soon,.

• VM - FEX and Nexus 1000v relationship

  Hello

  I'm new in the world of virtulaization and I need to know what the relationship between Cisco Nexus 1000v and Cisco VM - FEX? and when to use VM - FEX and when to use Nexus 1000v.

  Concerning

  Ahmed,

  Nexus 1000v is a Distributed Switch that allows you to manage your VEM, see this relationship as a supervisor-LineCard relationship.

  VM - FEX gives you the opportunity to bypass the vSwitch embarked on each host ESXi (VEM) for example.

  With VM - FEX, you see the virtual machines as if they were directly connected to the Parent switch (N7K / 5K for example), making it the parent spend management (cause there is more no vSwitch in the middle).

  This is a good topic that can be discussed and is difficult to summarize in a few lines, you read something in particular? any questions or doubts we can help clarify?

• Nexus 1000v and vMotion/VM traffic?

  Hello

  We are moving our servers of VM production to a new data center.

  There is a willingness to use the ports of 2 x 10 giga on each ESX host for the uplinks (etherchannel) Nexus 1000v for vMotion traffic and traffic VM.

  I don't know if that's even possible/supported? To devote nexus 1000v for vMotion and VM traffic ports at the same time? I think each guest will need an address unique IP for vMotion be able to operate.

  Best regards

  / Pete

  Info:

  vCenter/ESXi - 5.0 Update 3

  Yes - the characteristics of vmotion still apply if you use a virtual switch Standard or Distributed Virtual Switch as the Nexus 1000v - you should have a network for vmotion and each port vmkernel will need a unique IP address on the subnet of vmotion

• Nexus 1000v and vmkernel ports

  What is the best practice to put on the nexus 1000v vmkernel ports? Is it a good idea to put all the ports of vms and vmkernel on nexus 1000v? switch or dvs or some vmkernel as management ports must be on a standard?  If something happens to the 1000v, all management and vms will be unreachable.

  any tips?

  Yep, that's correct. Port system profiles don't require any communication between the MEC and VSM.

• Question about license for Nexus 1000v and it time to stand not licensed ESXi

  Hello

  I have the license for 12 cpu that are 3 popular ESXi with 4 processors each

  so if I add an another ESXi, which will support 60 days

  I'm pretty sure but wanted confirmation

  Thank you

  What version do you use? 2.1 they went to a model free and advanced, depending on the features you need, you can be able to upgrade and continue without additional licenses.

  No doubt, you can convert your current license VSG, contact your engineer.

• Design/implementation of Nexus 1000V

  Hi team,

  I have a premium partner who is an ATP on Data Center Unified Computing. He has posted this question, I hope you can help me to provide the resolution.

  I have questions about nexus 1KV design/implementation:

  -How to migrate virtual switches often to vswitch0 (in each ESX server has 3 vswitches and the VMS installation wizard will only migrate vswicht0)? for example, to other vswitchs with other vlan... Please tell me how...
  -With MUV (vmware update manager) can install modules of MEC in ESX servers? or install VEM manually on each ESX Server?
  -Assuming VUM install all modules of MEC, MEC (vib package) version is automatically compatible with the version of vmware are?
  -is the need to create port of PACKET-CONTROL groups in all THE esx servers before migrating to Nexus 1000? or only the VEM installation is enough?
  -According to the manual Cisco VSM can participate in VMOTION, but, how?... What is the recommendation? When the primary virtual machines are moving, the secondary VSM take control? This is the case with connectivity to all virtual machines?
  -When there are two clusters in a vmware vcenter, how to install/configure VSM?
  -For the concepts of high availability, which is the best choice of design of nexus? in view of the characteristics of vmware (FT, DRS, VMOTION, Cluster)
  -How to migrate port group existing Kernel to nexus iSCSI?... What are the steps? cisco manual "Migration from VMware to Cisco Nexus 1000V vSwitch" show how to generate the port profile, but
  How to create iSCSI target? (ip address, the username/password)... where it is defined?
  -Assuming that VEM licenses is not enough for all the ESX servers, ¿will happen to connectivity of your virtual machines on hosts without licenses VEM? can work with vmware vswitches?

  I have to install nexus 1000V in vmware with VDI plataform, with multiple ESX servers, with 3 vswitch on each ESX Server, with several machinne virtual running, two groups defined with active vmotion and DRS and the iSCSI storage Center

  I have several manuals Cisco on nexus, but I see special attention in our facilities, migration options is not a broad question, you you have 'success stories' or customers experiences of implementation with migration with nexus?

  Thank you in advance.

  I have questions about nexus 1KV design/implementation:
  -How migrate virtual switchs distint to vswitch0 (in each ESX server has 3 vswitches and the installation wizard of VMS only migrate vswicht0)?? for example others vswitchs with others vlan.. please tell me how...
  [Robert] After your initial installation you can easily migrate all VMs within the same vSwitch Port Group at the same time using the Network Migration Wizard.  Simply go to Home - Inventory - Networking, right click on the 1000v DVS and select "Migrate Virtual Machine Networking..."   Follow the wizard to select your Source (vSwitch Port Groups) & Destination DVS Port Profiles
  -With VUM (vmware update manager) is possible install VEM modules in ESX Servers ??? or must install VEM manually in each ESX Server?
  [Robert] As per the Getting Started & Installation guides, you can use either VUM or manual installation method for VEM software install.
  http://www.cisco.com/en/US/docs/switches/datacenter/nexus1000/sw/4_0_4_s_v_1_3/getting_started/configuration/guide/n1000v_gsg.html
  -Supposing of VUM install all VEM modules, the VEM version (vib package) is automatically compatible with build existen vmware version?
  [Robert] Yes.  Assuming VMware has added all the latest VEM software to their online repository, VUM will be able to pull down & install the correct one automatically.
  
  
  -is need to create PACKET-MANAGEMENT-CONTROL port groups in ALL esx servers before to migrate to Nexus 1000? or only VEM installation is enough???
  [Robert] If you're planning on keeping the 1000v VSM on vSwitches (rather than migrating itself to the 1000v) then you'll need the Control/Mgmt/Packet port groups on each host you ever plan on running/hosting the VSM on.  If you create the VSM port group on the 1000v DVS, then they will automatically exist on all hosts that are part of the DVS.
  -According to the Cisco manuals VSM can participate in VMOTION, but, how? .. what is the recommendation?..when the primary VMS is moving, the secondary VSM take control?? that occurs with connectivity in all virtual machines?
  [Robert] Since a VMotion does not really impact connectivity for a significant amount of time, the VSM can be easily VMotioned around even if its a single Standalone deployment.  Just like you can vMotion vCenter (which manages the actual task) you can also Vmotion a standalone or redundant VSM without problems.  No special considerations here other than usual VMotion pre-reqs.
  -When there two clusters in one vmware vcenter, how must install/configure VSM?
  [Robert] No different.  The only consideration that changes "how" you install a VSM is a vCenter with multiple DanaCenters. VEM hosts can only connect to a VSM that reside within the same DC.  Different clusters are not a problem.
  -For High Availability concepts, wich is the best choices of design of nexus? considering vmware features (FT,DRS, VMOTION, Cluster)
  [Robert] There are multiple "Best Practice" designs which discuss this in great detail.  I've attached a draft doc one on this thread. A public one will be available in the coming month. Some points to consider is that you do not need FT.  FT is still maturing, and since you can deploy redundany VSMs at no additional cost, there's no need for it.  For DRS you'll want to create a DRS Rule to avoid ever hosting the Primar & Secondary VSM on the same host.
  -How to migrate existent Kernel iSCSI port group to nexus? .. what are the steps? in cisco manual"Migration from VMware vSwitch to Cisco Nexus 1000V" show how to generate the port-profile, but
  
      how to create the iSCSI target? (ip address, user/password) ..where is it defined?
  [Robert] You can migrate any VMKernel port from vCenter by selecting a host, go to the Networking Configuration - DVS and select Manage Virtual Adapters - Migrate Existing Virtual Adapter. Then follow the wizard.  Before you do so, create the corresponding vEth Port Profile on your 1000v, assign appropriate VLAN etc.  All VMKernel IPs are set within vCenter, 1000v is Layer 2 only, we don't assign Layer 3 addresses to virtual ports (other than Mgmt).  All the rest of the iSCSI configuration is done via vCenter - Storage Adapters as usual (for Targets, CHAP Authentication etc)
  -Supposing of the licences of VEM is not enough for all ESX servers,, ¿will happen to the connectivity of your virtual machines in hosts without VEM licences? ¿can operate with vmware vswitches?
  [Robert] When a VEM comes online with the DVS, if there are not enough available licensses to license EVERY socket, the VEM will show as unlicensed.  Without a license, the virtual ports will not come up.  You should closely watch your licenses using the "show license usage" and "show license usage " for detailed allocation information.  At any time a VEM can still utilize a vSwitch - with or without 1000v licenses, assuming you still have adapters attached to the vSwitches as uplinks.
  I must install nexus 1000V in vmware plataform with VDI, with severals Servers ESX, with 3 vswitch on each ESX Server, with severals virtual machinne running, two clusters defined with vmotion and DRS active and central storage with iSCSI
  I have severals cisco manuals about nexus, but i see special focus in installations topics, the options for migrations is not extensive item, ¿do you have "success stories" or customers experiences of implementation with migrations with nexus?
  [Robert] Have a good look around the Nexus 1000v community Forum.   Lots of stories and information you may find helpful.
  Good luck!
  

• UCS environment vSphere 5.1 upgrade to vSphere 6 with Nexus 1000v

  Hi, I've faced trying to get the help of TAC and internet research on the way to upgrade to our UCS environment, and as a last thought resort, I would try a post on the forum.

  My environment is an environment of UCS chassis with double tracking, tissue of interconnections, years 1110 with pair HA of 1000v 5.1 running vsphere.  We have updated all our equipment (blades, series C and UCS Manager) for the supported versions of the firmware by CISCO for vSphere 6.

  We have even upgraded our Nexus 1000v 5.2 (1) SV3(1.5a) which is a support for vSphere version 6.

  To save us some treatment and cost of issuing permits and on our previous vcenter server performance was lacking and unreliable, I looked at the virtual migration on the vCenter 6 appliance.  There is nowhere where I can find information which advises on how to begin the process of upgrading VMWare on NGC when the 1000v is incorporated.  I would have thought that it is a virtual machine if you have all of your improved versions to support versions for 6 veil smooth.

  A response I got from TAC was that we had to move all of our VM on a standard switch to improve the vCenter, but given we are already on a supported the 1000v for vSphere version 6 that he left me confused, nor that I would get the opportunity to rework our environment being a hospital with this kind of downtime and outage windows for more than 200 machines.

  Can provide some tips, or anyone else has tried a similar upgrade path?

  Greetings.

  It seems that you have already upgraded your components N1k (are VEM upgraded to match?).

  Are your questions more info on how you upgrade/migration to a vcenter server to another?

  If you import your vcenter database to your new vcenter, it shouldn't have a lot of waste of time, as the VSM/VEM will always see the vcenter and N1k dVS.  If you change the vcenter server name/IP, but import the old vcenter DB, there are a few steps, you will need to ensure that the connection of VSM SVS corresponds to the new IP address in vcenter.

  If you try to create a new additional vcenter in parallel, then you will have problems of downtime as the name of port-profiles/network programming the guestVMs currently have will lose their 'support' info if you attempt to migrate, because you to NIC dVS standard or generic before the hosts for the new vcenter.

  If you are already on vcenter 6, I believe you can vmotion from one host to another and more profile vswitch/dVS/port used.

  Really need more detail on how to migrate from a vcenter for the VCA 6.0.

  Thank you

• Nexus 1000v password recovery

  I'm trying to recover the password on a Nexus 1000v VSM I cloned from our direct environment and spin in a nested workstation environment.

  When I try to start the installation ISO VSM, it is completely ignored and crosses all straight to the login page. If I created a new virtual machine without OS and boot from this same ISO it starts before the ISO as expected.

  Y at - there something I'm missing here, nobody knows exactly how to recover the password? I can't find any decent documentation on how to do it, just a simple chart with no details of Cisco.

  
  Any help would be appreciated!

  Thank you
  Adam

  Hi adhards,

  The bit that does not appear in the Cisco documentation is step 1 and step 2 below that must be performed on the virtual machine in question before you try to power up.

  1 change the settings > Options > Start Options > force the Bios Setup

  2. once in the BIOS screen move the cdrom to the top of the boot order.

  3. then, follow the instructions of recovery of password for Cisco Nexus 1000v
