• help required for cisco nexus 1000v

  Hello

  I have three esxi host in my environment and I want to integrate these hosts with cisco nexus 1000v switch.

  I installed vsm on host1 and adding the remaining host via vsm Update Manager. exchanges I have already create in SMV shown in the welcome that I've added to the vsm, but the port group is not shown on the host1 esx on which I have installed vsm, should I also add the host that contains MSM in the cisco nexus switch?

  I want to say that I have installed the MEC on any army three esxi. is it good?

  Hi Mohsin,

  Where did you read that? In the past, we have added the guests, including one who executes the VSM. Usually run us both VSMs (primamry and secondary) and add anti rules affinity so that the two VSMs are on different hosts. I'm not a person CISCO, but having worked with CISCO engineers, we had no problem with what you have just mentioned. It would really be a waste of host in my opinion. I don't see why this could be a problem... As long as you have all your trade (PGs for your packages VSM etc etc) in place, you should be able to add all hosts in my experience.

• 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.

• Why is - that someone would need Cisco Nexus 1000v when DvSwitch is so Kool

  Why is - that someone would need Cisco Nexus 1000v when DvSwitch is so Kool

  Or is it something that DvSwitch cannot always do that Cisco Nexus 1KV possible?

  Use of 1kV Nexus are clear enough, if you want to segregation, the advanced settings of COS, use Cisco VSG, etc. etc., you must use Nexus 1kV. But if you do not use one of these, why would you pay more money to use a Nexus 1kV, while you can use dvSwitch, giving you more or less the same basic features. After all, the 1kV has been developed using the dvSwitch framework.

• Cisco Nexus 1000v switch

  Hi, I have 2 questions about the Switch Cisco Nexus 1000v.

  First of all, why use it rather than the standard vswitch distributed?

  Second, if an environment currently works using distributed vswitches, what are the impacts and the problems likely to introduce a Switch Cisco Nexus 1000v? Is there a process for the upgrade?

  See you soon

  Here is a comparison for the most up-to-date between the optioins network:

  http://www.Cisco.com/en/us/prod/collateral/switches/ps9441/ps9902/solution_overview_c22-526262.PDF

  The great driver with most of the people running the 1000v I talked to is give visibility to the network team and streamlining changes made to the virtual network environment. In a great organazation with a network operations team, they will create an IVR to route a new VLAN, and then create the new VLAN on all switches distribution and access in the area of layer 2, just 1000v allows them to move forward and it create on the hypervisor using a set of commands that they already know.

• 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
  • DirectPath i/o - inactive "path Direct I/O has been explicitly disabled for this port.

  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!

  Bob

  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.

• Upgrade to vCenter 4.0 with Cisco Nexus 1000v installed

  Hi all

  We have vCenter 4.0 and ESX 4.0 servers and we want to upgrade to version 4.1. But also Nexus 1000v installed on the ESX Server and vCenter.i found VMware KB which is http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1024641 . But only the ESX Server upgrade is explained on this KB, vCenter quid?  Our vcenter 4.0 is installed on Windows 2003 64-bit with 64-bit SQL 2005.

  We can upgrade vcenter with Nexsus plugin 1000v installed upgrading on-site without problem? And how to proceed? What are the effects of the plugin Nexus1000v installed on the server vcenter during update?

  Nexus1000v 4.0. (version 4).sv1(3a) has been installed on the ESX servers.

  Concerning

  Mecyon,

  Upgrading vSphere 4.0-> 4.1 you must update the software VEM (.vib) also.  The plugin for vCenter won't change, it won't be anything on your VSM (s).  The only thing you should update is the MEC on each host.  See the matrix previously posted above for the .vib to install once you're host has been updated.

  Note: after this upgrade, that you will be able to update regardless of your software of vSphere host or 1000v (without having to be updated to the other).  1000v VEM dependencies have been removed since vSphere 4.0 Update 2.

  Kind regards

  Robert

• Cisco Nexus 1000V (separate host?)

  We look at this one I have not yet have my head wrapped around it, but, I think I understand:

  (1) you can have 1 or 2 VSM (primary and secondary)

  (2) Vincent becomes an integral part of the kernel for ESX 4 host you want managed by these VSMs

  (3) a VSM will manage only a single ESX cluster.

  My hypothesis is that these virtual devices VSM would live within the cluster, it runs along side VMs however; This diagram (attached) seems to show the VSM on an ESX host, which is not an instance of separate VEM?

  It seems that the benefit to this 1000V is less if you need to buy 1 (2 for HA) or the ESX hosts through a license to support these virtual appliances.

  I understand that correctly?

  Yes, we do like control and packages must be on their own NIC in reality you can stick them anywhere. The amount of traffic that send us via these networks is low (except package when you ERSPAN). On our side there is concern that, if the network is busy the VSM could lose a few heartbeats of the MEC and remove it. Looking at your environment I'd stick control and the package on the natachasery used for the Service Console. That way all your control traffic is isolated from VMK and data.

• The Cisco Nexus 1000V VSM port group settings?

  I could not find the Group of port settings when executing the VSM in a virtual machine covered in the Cisco documentation... they say just 'create 3 groups of port '.   But, the configuration of VLANS to these pages are not clear to me.

  In the configuration of VSM, you set the VLAN on each network (Mgmnt, control, package).   This means that the VM VSM will be production of marked packets, so groups of port must be set as master / virtual tag comments.

  But, if this is the case, why they recommend 3 groups of ports?  You should be able to use a trunk port group and letting the physical switch the VLAN.  Thus, they rather waiting for assignment of VLAN will be on the Port groups?

  The Cisco config docs give much information on the Cisco command line configuration...  Some may give, or point, the settings on the VMware port groups when using MSM in a virtual machine?

  Hello

  VSM virtual machine generates no marked packets but depends on the configuration of the port group VLAN ID Vswitch to label.  It's done as having evacuated the computer host computer on the vmnic associated the Vswitch.

• 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?

  -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

  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!
  

• 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.

• iSCSI MPIO (Multipath) with Nexus 1000v

  Anyone out there have iSCSI MPIO successfully with Nexus 1000v? I followed the Cisco's Guide to the best of my knowledge and I tried a number of other configurations without success - vSphere always displays the same number of paths as it shows the targets.

  The Cisco document reads as follows:

  Before you begin the procedures in this section, you must know or follow these steps.

  •You have already configured the host with the channel with a port that includes two or more physical network cards.

  •You have already created the VMware kernel NIC to access the external SAN storage.

  •A Vmware Kernel NIC can be pinned or assigned to a physical network card.

  •A physical NETWORK card may have several cards pinned VMware core network or assigned.

  That means 'a core of Vmware NIC can be pinned or assigned to a physical NIC' average regarding the Nexus 1000v? I know how to pin a physical NIC with vDS standard, but how does it work with 1000v? The only thing associated with "pin" I could find inside 1000v was with port channel subgroups. I tried to create a channel of port with manuals subgroups, assigning values of sub-sub-group-id for each uplink, then assign an id pinned to my two VMkernel port profiles (and directly to ports vEthernet as well). But that doesn't seem to work for me

  I can ping both the iSCSI ports VMkernel from the switch upstream and inside the VSM, so I know Layer 3 connectivity is here. A strange thing, however, is that I see only one of the two addresses MAC VMkernel related on the switch upstream. Both addresses show depending on the inside of the VSM.

  What I'm missing here?

  Just to close the loop in case someone stumbles across this thread.

  In fact, it is a bug on the Cisco Nexus 1000v. The bug is only relevant to the ESX host that have been fixed in 4.0u2 (and now 4.1). Around short term work is again rev to 4.0u1. Medium-term correction will be integrated into a maintenance for the Nexus 1000V version.

  Our implementation of code to get the multipath iSCSI news was bad but allowed in 4.0U1. 4.0U2 no longer our poor implementation.

  For iSCSI multipath and N1KV remain 4.0U1 until we have a version of maintenance for the Nexus 1000V
