• Nexus1000v on Hyper-V, adding a VEM a host has no

  Hi all

  I have Hyper-V with Wndows server host 2012 R2 installed on it and System Center Virtual Machine Manager R2 2012. I manually installed Nexus1000v VSM. Everything is OK, but when I try to add the virtual switch to a Hyper-V host a get on 2012R2 SCVMM error message:

  Error (25138)

  The following need drivers (9c8ed422-f33a-4f34-b771-e8b8d0539fd3) are not or the installation packages (files. (MSI) with the supported version are not.

  Recommended action

  Reinstall the provider configuration for the virtual switch extensions manager that feeds these drivers.

  I'm already copied Nexus1000V-VEM - 5.2.1.SM1.5.1.0.msi file to a specified location C:\ProgramData\Switch Extension drivers on a Hyper-V host.

  Something wrong?

  If you have any ideas please respond to this email.

  Best regards

  The N1k Hyper-V does not currently support Windows 2012 R2.  My guess is that he's looking for the MSI to R2, but can't find it (because it is not supported)

  The next version is currently in beta and is expected in the coming months.

• RSPAN - if the destination port is 'across' other switches 3560 X

  3560 X

  Having a configuration switch to a local port (source Gi0/14 - destination Gi0/20) SPAN.

  It works very well.

  Now, I need to send copies to * another * switch to that same destination port.

  I know I can do RSPAN to do this, but I have two questions.

  1. any question of having two different litters towards one destination?

  2. each switch between the source switch and destination should any config? Or just the source button?

  Mark,

  You need to use a vlan between the switches to move the span.

  See this guide for an example of a config

• Nexus1000V load balancing

  Hello

  could someone help me to clarify this...

  In our environment, we have a Nexus1000V. VEM is connected to two switches uplink. At this point neither mac-pinning or vPC - HM are used and nexus is running the default load balancing mechanism (source-mac). I see a mac-beating on the switches uplink to servers in the VCenter. If source-mac has been used should not the mac address of a virtual machine be persistent on a specific switch, assuming he is not moved to an another ESXi?

  We intend to change our port to link rising-profiles mac - pinning or vPC - HM. The documentation states that, in this case, the virtual machines are associated with an uplink of alternating. So, what is the use of the load balancing in this case? Load Balancing have effect only if good LACP is trained (stackable switches etc.)?

  One last question:

  If mac - pinning is used and a link fails, then all vm traffic will be sent to the second link. If the first link is displayed again, while traffic for virtual machines that have been associated with the first link, be moved to the first or the traffic will continue to flow on the second?

  Thank you in advance,

  Katerina

  Hi Katerina,

  I have configured my lab for "auto channel-group" and the two links are in a port channel.

  MEC considered the two uplinks as the same interface.

  Module # 4 N1K vem run vemcmd see the port
  The State of the link Admin LTL VSM Port PC - LTL SGID Vem Port Type
  19 Eth4/3 UP UP F / 1039 B * 0 vmnic2
  20 Eth4/4 UP UP F / 1039 B * 0 vmnic3
  49 UP UP FWD 0 0 vmk1 Veth9

  * SGID designates sup group ID

  After the release, Vmk1 traffic can take vmnic2 or vmnic3. N1k sees this as an outgoing interface port-channel. In order to avoid the beating of mac, we need to configure the two switchports upstream in a logical interface.

  Now, MAC pinning configured, run us the same command

  Module # 4 N1K vem run vemcmd see the port
  The State of the link Admin LTL VSM Port PC - LTL SGID Vem Port Type
  19 Eth4/3 UP UP F / 1040 B * 2 vmnic2
  20 Eth4/4 UP UP F / 1040 B * 3 vmnic3
  49 UP UP FWD 0 2 vmk1 Veth9

  vmnic2 and vmnic3 are considered two different outgoing interfaces. There is no switchport upstream requirements.

• Nexus1000v Client plugin

  Hi all

  
  

  I'm trying the Nexus 1000v on vsphere standard 6.0 for the purposes of a blog.

  
  

  
  

  The Virtual Switch Update Mnager plugin does not appear on http://vcenter:9443

  I have a small laboratory installed and I would like to test the standard edition of Nexus 1000v. Two ESXi hosts and vcenter server 6.0 windows.

  I installed the Manager to update the VM virtual switch with IP 10.0.0.21. It can ping vcenter and its gateway. I also checked the logs and there is no error to connect to vcenter.

  "With the help of CATALINA_PID: /usr/local/tomcat/catalina.pid.

  Seat of app with vCenter.

  "DEBUGGING com.virtuata.security.TunnelFactory - socket opening tunnel is completed.

  ' 1280 [main] com.virtuata.security.VirtuataTunneledSSLSocketFactory debug - syringe socket is created "

  But the plugin still does not appear.

  
  I did some reading and told that the virtual switch Update Manager VM will install and register but the plugin will not appear if there is a problem with the license. I have Enterprise Plus for Vsphere and the vcenter server is an assessment. Is this o

  
  

  
  

  10.0.0.3 et.7 are ESXi hosts. VCA is the vcenter server.

  
  

  On the licenses page, I select capital and see the following topics:

  10.0.0.3-> VMware vshpere 6 plu enterprise (unlimited cores per processor)-> < xxx.xxxx.xxx.xxx.xxx.xxx > -> never expires

  10.0.0.7 -> VMware vshpere 6 company more (unlimited cores per processor)-> < key > -> never expires

  VCA -> evaluation -> < no license key > -> mode expires x/x/x

  
  

  I'm trying to add the license key I use pour.3 a.7 VCA but it errors and says that is not valid. Any ideas? Do I need another company key to the actual vcenter server more.

  
  

  In my view, that the switch has been deployed as an OVF in the vCenter.

  Please download and save the extension.xml after accessing the IP switching from a browser and try to save it by following the instructions below.

• Nexus1000v and vCenter Linked Mode

  Hello

  Is that what someone has implemented Nexus1000v in an environment with vCenter Linked Mode active? The VMware support guy says he only is not supported, but in my research in cisco and vmware Web sites I have found no documentation confirming this information.

• Port channel is not an option for the Destination RSPAN reflector Port

  Hello

  The trunk of our N3024 and N2048 is a channel port LAG (m 1).

  When you set the destination to distance type VLAN, it ask Destination Port of reflector which I guess must be the chest. 1 Q. Among the registered interfaces, in. interfaces are not an option.

  Why? How to proceed now?

  Thank you!

  I just checked and the switch will not let you set the destination to a vlan remote without going through a reflector port. The only thing I can think is to run another line between switches and use it as a reflector port. Or get rid of the channel port.

• Nexus1000v: Change "max-ports" disruptive?

  Hello

  I ve change "max-ports" in a port-profile vethernet.

  This command causes a disturbance on the other virtual machines?

  Version of Nexus 1000v 4.2 (1) SV1 (4)

  Thank you!

  Andreas,

  Increase the number of port with the max-port setting does not affect existing traffic.

• Nexus 1010 Services Virtual Appliance and VN-link hardware

  All,

  We deploy the Nexus 1010 Virtual Appliance service in order to use the analysis network (NAM) Module.  The 1010 necessary hosted of the MSM to deploy the 1000v switch into ESX.  We would also use VN-Link in the material by which we "get around" the virtual switch and use the 6120's for switching.  What I need to know, it's possible the 1010 always to analyze network traffic using hardware VN-link?  Hardware VN-link does not seem to need a VSM, so I think that the 1010 cannot monitor traffic because there is no "attach" to 1000v.  Anyone can shed some light on this?

  Kind regards

  Ken

  Ken

  The NAM module present in the 1010 is not exclusive for Nexus1000v traffic.

  Its there as part of a device which is be the VSM (1000v) and is set on its own.

  If you look at the Nexus1000v, the VSM (which is the 1010 and holds the NAM in this case) is * not * part of the VM data path.

  He's wanted for initial virtual port instantiations (veth) but after that the traffic does not go through it.

  So to send data traffic VM to the NAM module for analysis, another mechanism (such as ERSPAN) is used to route the data traffic of the VM is to her.

  The Nexus 1000v support ERSPAN.

  Same logic applies you have a NAM module-the 1000v can send traffic to it through ERSPAN.

  Looking to VN-link in hardware - there a MSM which is the INSTITUTION itself.

  In this case, the veth is on FI.

  If the FI did support ERSPAN (which is not currently), you can use the same NAM module or any other module of NAM for sending traffic to it.

  If this isn't a limitation of VN-link in hw methodology vs 1000v switching switching, but the fact that the FI does not yet support a mechanism of 'export '.

  I hope it helps

  Thank you

• UCS 1.4 support for PVLAN

  Hi all

  Cisco UCS 1.4 Adviser supports PVLAN. But I see the following comment on PVLAN in point 1.4 of the UCS

  "UCS extends PVLAN support for virtualized (without vSwitch) deployments."

  "UCS release 1.4 (1) supports isolated PVLAN support for physical server paths or Palo NAC vNIC ports."

  Is that means PVLAN will not work for the virtual machine if VMs is connected to the UCS by Nexus1000v or vDS even if I use the card of PALO (M81KR)?

  Could someone can confirm that?

  Thank you very much!

  Hello

  Yes - PVLANs must be from end to end.

  You can extend the PVLAN set to 1000v and then to bare metal (attached to UCS) servers to a port promiscous * outside * UCS as a backup station or a L3 interface.

  Pls remember that promiscous ports are not supported in UCS. Only access isolated at the moment.

  With the M81KR adapter (Palo), you must create a diff for each interface isolated VLAN (as UCS cannot do isolated trunks yet).

  In you case you seem to have 1 isolated VLAN vNIC so 4 total giving to the 1000v running ESX.

  2 vNIC for VLAN regular (load sharing and redundancy)

  2 network cards for the VLAN isolated (load sharing and redundnacy).

  See attached a doc that talking abt doing which I think is what you're asking.

  Thank you

• problems with the IPCC monitoring server port

  I have 4.0 (4) IPCC Express Premium with Call Manager 4.1 (2). I have a server with two NIC a 'normal' IPCC and other oversight bodies. I have configured the port monitoring with a few other IP (172.16.255.10/24) and I set up RSPAN on switches. I see a call between officers and the appellants.

  But, after a reboot of the server, I get the error that my server will stop after a minute. I cann't see ane packages from monitor port. When I disable the port monitor and restart the server everything is OK and then I can activate the monitor port and everything is OK.

  I have nothing in the registry settings.

  What should do?

  Thank you

  I had the same problem as you and this has solved my problem.

• Update the IOS link on a 1000v

  Someone at - it good documentation on the process of upgrading my nexus 1000v 1000v - mz.4.2.1.SV1.4 to Nexus1000v.4.2.1.SV1.4a?  The first time on Nexus IOS and want to spend before it goes into production, but have a hard time finding detailed steps.  Thank you!

  I followed this process recently, it was pretty simple. However, I would follow this guide only for upgrades of the VSM. When it comes to upgrading the VEM I used VMware Update Manager rather than it was an easier process.

  http://www.Cisco.com/en/us/docs/switches/Datacenter/nexus1000/SW/4_2_1_s_v_1_4_a/upgrade/software/guide/n1000v_upgrade_software.html#wp631911

• Problem with MAC pinning and new VLAN

  [Cross Announces nexus 1000V and forums of the UCS]

  Hi all, I have a working of the UCS 1.4 configuration (3i) and the Nexus 1000V 1.4 and according to best practices guide uses "channel-group auto on mac - pinning mode" on the uplink of Nexus. I have a problem when you add a new VLAN in this environment, and it is a reproducible problem in two different facilities.

  I pass by the VLAN usual creation process on the Nexus, the network upstream and within the UCS himself. I create new port vethernet profile and set it as an access port in the new VIRTUAL LAN. However when I join a VM (existing or new) to this new port vethernet profile in vCentre virtual machine cannot communicate with anything. However, if I disable MAC pinning with 'no channel-group auto on mac - pinning mode', the virtual machine will start instantly talk to the outside world and the new VIRTUAL LAN is running. Can I turn MAC pinning back once again, and everything continues to work.

  So the question is, is this normal or is there a problem? MAC the Θtiquetage has a brief interruption of the uplink, so is not a viable long-term customer solution when they want to add new VLAN. Is it possible to add new VLANS in this scenario without any unavailability of the network, but brief?

  Thank you

  Close the loop on this.  You tap the CSCto00715bug.

  Symptom: New MAC address is not learn on vem in the l2 table even though the mac address table is not overflow yet. vemcmd show l2-emergency-aging-stats | grep "Number of entries that could not be inserted:" will show extreme large number. Conditions: Nexus1000v VEM running on SV1.4 release. There are two CPU cores on the host. This issue may happen at race condition. Workaround: Reboot the ESX/ESXi host. 

  This problem is corrected in the 1. 4A release.

  Kind regards

• IPS-4240 design question

  I have two IPS 4240 s that can be placed between our internal network and our extranet firewall. The game of firewall is your pair of standard assets/ASA-5520 switch connected to both switches.

  Q1 - if I'm not worried about atomic attacks, is there another advantage that IPS inline on promiscuity?

  Is Q2 - If inline or promiscuity, necessary to connect the unique IPS for two switches in order to receive packets when a failover of the SAA occurs? If so, does physically or through RSPAN?

  Q3 - if the IPS fails and it is set online, interfaces fail open (traffic continues to pass) or closed (traffic is removed)? I couldn't find that on the Cisco site.

  Thank you!

  "Promiscuous" mode, you can use a 4240 and extend the output of each switch in two interfaces of remote sensing of the 4240 (it has four available). A single 4240 should even be able to set up TCP sessions that span the two rails, as in the case of a failover.
