• 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.

• 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.

  Thank you.

  I had the same question, so I opened a folder of TAC to find the version of the software. I was told that the software listed as available in the bug report are versions of NX - custom OS and that there was no version patched for the 5548p. The support engineer also said that the updates of Nexus 5 k should not until November or December. The best advice I could get was to subscribe to the bug report and wait to be notified of an available upgrade.

• 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.

• Restoration of Cisco Nexus 1000V - Host-ID fingerprint

  Someone find some information about how to restore a Cisco Nexus 1000V?

  The license is the result of a fingerprint of the identifier of the VSM. In case we lose the VM with VSM or host ESX Server must be reinstalled, this print is different. So that would mean the licensekey need, it's be regenerated.

  Has anyone found information on it?

  Can Q: you a VSM vMotion?

  A: we do not recommend it.

• 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

• 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.

• 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.

• Problems to install the plugin extension of Nexus 1000v vCenter file "invalid URI: the URI is empty.

  Hi all

  I try to install the Cisco Nexus 1000v switch in my training lab.

  When I get to the stage where I add the Extension XML file to the vSphere Plugin Manager, I get an error stating that "invalid URI: the URI is empty.

  When I open the cisco_nexus_1000v_extension.xml file, obviously, there is something missing in the & lt; URL & gt; & lt; / url & gt; section.

  The Cisco NX - OS dialing software

  Software Cisco NX - OS is a data-center-class operating system that provides a high thanks to a modular design availability. The Cisco NX - OS software is software-based Cisco MDS 9000 SAN - OS and it supports the Cisco Nexus series switch Cisco MDS 9000 series multilayer. The Cisco NX - OS software contains a boot kick image and an image of the system, the two images contain an identifier of major version, minor version identifier and a maintenance release identifier, and they may also contain an identifier of reconstruction, which can also be referred to as a Patch to support. (See Figure 6).

  Software NX - OS Cisco Nexus 7000 Series and MDS 9000 series switches use the numbering scheme that is illustrated in Figure 6.

  Figure 6. Switches of the series Cisco IOS dial for Cisco Nexus 7000 and MDS 9000 NX - OS

  

  For the other members of the family, software Cisco NX - OS uses a combination of systems independent of the platform and is dependent on the platform as shown in Figure 6a.

  Figure 6 a. software Cisco IOS NX - OS numbering for the link between 4000 and 5000 Series and Nexus 1000 switches virtual

  

  The indicator of the platform is N for switches of the 5000 series Nexus, E for the switches of the series 4000 Nexus and S for the Nexus 1000 series switches. In addition, Nexus 1000 virtual switch uses a designation of two letters platform where the second letter indicates the hypervisor vendor that the virtual switch is compatible with, for example V for VMware. Features there are patches in the platform-independent code and features are present in the version of the platform-dependent Figure 6 a above, there is place of bugs in the version of the software Cisco NX - OS 4.0(1a) are present in the version 4.0(1a) N1(1a).
