• Nexus 1000v VSM compatibility with older versions of VEM?

  Hello everyone.

  I would like to upgrade our Nexus 1000v VSM 4.2 (1) SV1 (5.1) to 4.2 (1) SV2(2.1a) because we are heading of ESXi 5.0 update 3 to 5.5 ESXi in the near future. I was not able to find a list of compatibility for the new version when it comes to versions VEM, I was wondering if the new VSM supports older versions VEM, we are running, so I must not be upgraded all at once. I know that it supports two versions of our ESXi.

  Best regards

  Pete

  You found documentation, transfer of the station from 1.5 to latest code is supported in a VSM perspective.  Which is not documented is the small one on the MEC.  In general, the VSM is backward compatible with the old VEM (to a degree, the degree of which is not published).  Although it is not documented (AFAIK), verbal comprehension is that MEC can be a version or two behind, but you should try to minimize the time that you run in this configuration.

  If you plan to run mixed versions VEM when getting your upgraded hosts (totally fine that's how I do mine), it is better to move to this enhanced version of VEM as you upgrade the hypervisor.  Since you go ESXi 5.0 5.5, you create an ISO that contains the Cisco VIBs, your favorite driver async (if any), and the image of ESXi 5.5 all grouped together so the upgrade for a given host is all of a sudden.  You probably already have this cold technique, but the links generated by the Cisco tool below will show you how to proceed.  It also gives some URLS handy to share with each person performing functions on this upgrade.  Here is the link:

  Nexus 1000V and ESX upgrade utility

  PS - the new thing takes clones your VSMs offline.  Even if they are fairly easy to recover, having a real pure clone will save some sauce secret that otherwise you may lose in a failure scenario.  Just turn off a VSM, then right click and clone.  Turn on again this MSM and failover pair HA, then take to the bottom of it and get a clone of it.  So as a security measure, this upgrade, get your clones currently out of the current 1.5 VSMs, then some time after your upgrade some clones offline, saved from the new version.

  Doan,

  Need more information.

  The reception was added via vCenter to DVS 1000v successfully?

  If so, there is probably a problem with your control communication VLAN between the MSM and VEM.  Start here and ensure that the VIRTUAL local area network has been created on all intermediate switches and it is allowed on each end-to-end trunk.

  If you're still stuck, paste your config running of your VSM.

• 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

• 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

  Hey guys,.

  Hope this is the right place to post.

  IM currently working on a design legacy to put in an ESXi 5 with Nexus 1000v solution and a back-end of a Cisco UCS 5180.

  I have a few questions to ask about what people do in the real world about this type of package upward:

  In oder to use the Nexus 1000v - should I vCenter?  The reason why I ask, is there no was included on the initial list of the Kit.  I would say to HA and vMotion virtual Center, but the clients wants to know if I can see what we have for now and licenses to implement vCenter at a later date.

  Ive done some reading about the Nexus 1000v as Ive never designed a soluton with that of before.  Cisco is recommended 2 VSM be implemented for redundancy.  Is this correct?  Do need me a license for each VSM?  I also suppose to meet this best practice I need HA and vMoton and, therefore, vCenter?

  The virtual machine for the VSM, can they sit inside the cluster?

  Thanks in advance for any help.

  In oder to use the Nexus 1000v - should I vCenter?

  Yes - the Nexus 1000v is a type of switch developed virtual and it requires vcenetr

  I'm not sure the VSMs but yes HA and vMotion are required as part of best practices

  The virtual machine for the VSM, can they sit inside the cluster?

  Yes they cane xist within the cluster.

• Nexus 1000v - this config makes sense?

  Hello

  I started to deploy the Nexus 1000v at a 6 host cluster, all running vSphere 4.1 (vCenter and ESXi). The basic configuration, license etc. is already completed and so far no problem.

  My doubts are with respect to the actual creation of the uplink system, port-profiles, etc. Basically, I want to make sure I don't make any mistakes in the way that I want to put in place.

  My current setup for each host is like this with standard vSwitches:

  vSwitch0: 2 natachasery/active, with management and vMotion vmkernel ports.

  vSwitch1: natachasery 2/active, dedicated to a storage vmkernel port

  vSwitch2: 2 natachasery/active for the traffic of the virtual machine.

  I thought that translate to the Nexus 1000v as this:

  System-uplink1 with 2 natachasery where I'm putting the ports of vmk management and vMotion

  System-uplink2 with 2 natachasery for storage vmk

  System-uplink3 with 2 natachasery for the traffic of the virtual machine.

  These three system uplinks are global, right? Or I put up three rising system unique for each host? I thought that by making global rising 3 would make things a lot easier because if I change something in an uplink, it will be pushed to 6 guests.

  Also, I read somewhere that if I use 2 natachasery by uplink system, then I need to set up a channel of port on our physical switches?

  At the moment the VSM has 3 different VLAN for the management, control and packet, I want to migrate the groups of 3 ports on the standard switch to the n1kv itself.

  Also, when I migrated to N1Kv SVS management port, host complained that there no redundancy management, even if the uplink1 where mgmt-port profile is attached, has 2 natachasery added to it.

  While the guys do you think? In addition, any other best practices are much appreciated.

  Thanks in advance,

  Yes, uplink port-profiles are global.

  What you propose works with a warning. You cannot superimpose a vlan between these uplinks. So if your uplink management will use vlan 100 and your uplink of VM data must also use vlan 100 which will cause problems.

• Nexus 1000v deployment issues

  I'm working on the Cisco Nexus 1000v deployment to our ESX cluster. I have read the Cisco "Start Guide" and the "installation guide" but the guides are good to generalize your environment and obviously does not meet my questions based on our architecture.

  This comment in the "Getting Started Guide" Cisco makes it sound like you can't uplink of several switches on an individual ESX host:

  «The server administrator must assign not more than one uplink on the same VLAN without port channels.» Affect more than one uplink on the same host is not supported by the following:

  A profile without the port channels.

  Port profiles that share one or more VLANS.

  After this comment, is possible to PortChannel 2 natachasery on one side of the link (ESX host side) and each have to go to a separate upstream switch? I am creating a redundancy to the ESX host using 2 switches but this comment sounds like I need the side portchannel ESX to associate the VLAN for both interfaces. How do you manage each link and then on the side of the switch upstream? I don't think that you can add to a portchannel on this side of the uplink as the port channel protocol will not properly negotiate and show one side down on the side ESX/VEM.

  I'm more complicate it? Thank you.

  Do not portchannel, but it is possible the channel port to different switches using the pinning VPC - MAC mode. On upstream switches, make sure that the ports are configured the same. Same speed, switch config, VLAN, etc (but no control channel)

  On the VSM to create a unique profile eth type port with the following channel-group command

  port-profile type ethernet Uplink-VPC

  VMware-port group

  switchport mode trunk

  Automatic channel-group on mac - pinning

  no downtime

  System vlan 2.10

  enabled state

  What that will do is create a channel port on the N1KV only. Your ESX host will get redundancy but your balancing algorithm will be simple Robin out of the VM. If you want to pin a specific traffic for a particular connection, you can add the "pin id" command to your port-type veth profiles.

  To see the PIN, you can run

  module vem x run vemcmd see the port

  n1000v-module # 5 MV vem run vemcmd see the port

  LTL VSM link PC - LTL SGID Vem State Port Admin Port

  18 Eth5/2 UP UP FWD 1 305 vmnic1

  19 Eth5/3 UP UP FWD 305 2 vmnic2

  49 Veth1 UP UP 0 1 vm1 - 3.eth0 FWD

  50 Veth3 UP UP 0 2 linux - 4.eth0 FWD

  Po5 305 to TOP up FWD 0

  The key is the column SGID. vmnic1 is SGID 1 and vmnic2 2 SGID. Vm1-3 VM is pinned to SGID1 and linux-4 is pinned to SGID2.

  You can kill a connection and traffic should swap.

• Cisco Nexus 1000V Virtual Switch Module investment series in the Cisco Unified Computing System

  Hi all
  I read an article by Cisco entitled "Best practices in Deploying Cisco Nexus 1000V Switches Cisco UCS B and C Series series Cisco UCS Manager servers" http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9902/white_paper_c11-558242.html

  A lot of excellent information, but the section that intrigues me, has to do with the implementation of module of the VSM in the UCS. The article lists 4 options in order of preference, but does not provide details or the reasons underlying the recommendations. The options are the following:

  ============================================================================================================================================================
  Option 1: VSM external to the Cisco Unified Computing System on the Cisco Nexus 1010

  In this scenario, the virtual environment management operations is accomplished in a method identical to existing environments not virtualized. With multiple instances on the Nexus 1010 VSM, multiple vCenter data centers can be supported.
  ============================================================================================================================================================

  Option 2: VSM outside the Cisco Unified Computing System on the Cisco Nexus 1000V series MEC

  This model allows to centralize the management of virtual infrastructure, and proved to be very stable...
  ============================================================================================================================================================

  Option 3: VSM Outside the Cisco Unified Computing System on the VMware vSwitch

  This model allows to isolate managed devices, and it migrates to the model of the device of the unit of Services virtual Cisco Nexus 1010. A possible concern here is the management and the operational model of the network between the MSM and VEM devices links.
  ============================================================================================================================================================

  Option 4: VSM Inside the Cisco Unified Computing System on the VMware vSwitch

  This model was also stable in test deployments. A possible concern here is the management and the operational model of the network links between the MSM and VEM devices and switching infrastructure have doubles in your Cisco Unified Computing System.
  ============================================================================================================================================================

  As a beginner for both 100V Nexus and UCS, I hope someone can help me understand the configuration of these options and equally important to provide a more detailed explanation of each of the options and the resoning behind preferences (pro advantages and disadvantages).

  Thank you
  Pradeep

  No, they are different products. vASA will be a virtual version of our ASA device.

  ASA is a complete recommended firewall.

• 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.

• How change 1010 Nexus and Nexus 1000v IP address

  Hi Experts,

  We run two VSM and a NAM in the Nexus 1010. The version of Nexus 1010 is 4.2.1.SP1.4. And the Nexus 1000v version is 4.0.4.SV1.3c. Now we need to change the IP address of management in the other. Where can I find the model SOP or config? And nothing I need to remember?

  If it is only the mgmt0 you IP address change, you can simply enter the new address under the mgmt0 interface. It automatically syncs with the VC.

  I guess you are trying to change the IP address of the VC and the management VLAN. One way to do this is:

  -From the Nexus 1000v, disconnect the connection to the VC (connection svs-> without logging)

  -Change the IP address of the VC and connect (connection-> remote ip address svs)

  -Change the address for mgmt0 Nexus 1000v

  -Change the mgmt VLAN on the 1010

  -Change the address of the 1010 mgmt

  -Reconnect the Nexus 1000v to VC (connection-> connect svs)

  Therefore, to change the configuration of VLANS on the switch upstream, more connection to the VC as well.

  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

• Cisco Nexus 1000V - DMZ - ARP

  Hello

  Thanks for reading.

  I have a virtual (VM1) connected to a Nexus 1000V distributed switch.  The willing 1000V of a connection to our DMZ (physically, an interface on our Cisco ASA 5520) which has 3 other virtual machines that are used successfully to the top in the demilitarized zone.  The problem is that a SHOW on the SAA ARP shows the other VM addresses MAC but not VM1.

  The properties for all the VMS (including VM1) participating in the demilitarized zone are the same:

  • Tag network
  • VLAN ID
  • Port group
  • State - link up

  The only important difference between VM1 and the others is that they are multihomed agents and have one foot in our private network.  I think that the absence of a private IP VM1 is not the source of the problem.  All virtual machines recognized as directly connected to the ASA (except VM1).

  Have you ever seen this kind of thing before?

  Thanks again for reading!

  The systems team:

  1. Rebuilt the virtual machine
  2. Moved to another cluster
  3. Configured for DMZ interface

  Something that they got the visible VM to the FW.
