I need to transmit both the private-vlans (as promiscous trunk) and regular vlans on the trunk port between the Nexus 1000V and the physical switch. Do you know how to properly configure the uplink port to accomplish that ?
Thank you in advance
Lucas
Control vlan is a totally seperate VLAN then your System Console. The VLAN just needs to be available to the ESX host through the upstream physical switch and then make sure the VLAN is passed on the uplink port-profile that you assign the ESX host to.
We only need an interface on the ESX host if you decide to use L3 control. In that instance you would create or use an existing VMK interface on the ESX host.

Nexus 1010 + 1000v control vlan issue
Hi,
I have Nexus 1000v installed on nexus 1010. The nexus 1010 is in cluster and working fine. I have made network uplink option 3.
My VSM is configured to be on L3 mode. Hence I set control and packet vlan to 1 (on vsm). while creating the VSB too I have choosen control and packet vlan to be 1 (keeping in mind my mode will be L3).
Now The vsm is not coming up in HA. The redandancy log says degraded mode is true.
Is it because, the control packet coming from VSM after reaching the N1010, the packets are getting tagged with vlan 1. Since I have not set any native vlan on 1010, might be control vlan 1 is also tagged one. Is it this the case ?
help needed on this issue.
regards

Nexus 1000v: Control VLAN must be same VLAN as ESX hosts?
Hello,
I'm trying to install nexus 1000v and came across the below prerequisite.
The below release notes for Nexus 1000v states
VMware and Host Prerequisites
The VSM VM control interface must be on the same Layer 2 VLAN as the ESX 4.0 host that it manages. If you configure Layer 3, then you do not have this restriction. In each case however, the two VSMs must run in the same IP subnet.
What I'm trying to do is to create 2 VLANs - one for management and the other for control & Data (as per latest deployment guide, we can put control & data in the same vlan).
However, I wanted to have all ESX host management same VLAN as the VSM management as well as the vCenter Management. Essentially, creating a management network.
However, from the above "VMWare and Host Prerequisites", does this means I cannot do this?
I need to have the ESX host management same VLAN as the control VLAN?
This means that my ESX host will reside in a different VLAN than my management subnet?

I am having some problems with VSM/VEM connectivity after an upgrade that I'm hoping someone can help with.
I have a 2 ESXi host cluster that I am upgrading from vSphere 5.0 to 5.5u1, and upgrading a Nexus 1000V from SV2(2.1) to SV2(2.2). I upgraded vCenter without issue (I'm using the vCSA), but when I attempted to upgrade ESXi-1 to 5.5u1 using VUM it complained that a VIB was incompatible. After tracing this VIB to the 1000V VEM, I created an ESXi 5.5u1 installer package containing the SV2(2.2) VEM VIB for ESXi 5.5 and attempted to use VUM again but was still unsuccessful
I removed the VEM VIB from the vDS and the host and was able to upgrade the host to 5.5u1. I tried to add it back to the vDS and was given the error below:
vDS operation failed on host esxi1, Received SOAP response fault from [<cs p:00007fa5d778d290, TCP:esxi1.gooch.net:443>]: invokeHostTransactionCall
Received SOAP response fault from [<cs p:1f3cee20, TCP:localhost:8307>]: invokeHostTransactionCall
An error occurred during host configuration. got (vim.fault.PlatformConfigFault) exception
I installed the VEM VIB manually at the CLI with 'esxcli software vib install -d /tmp/cisco-vem-v164-4.2.1.2.2.2.0-3.2.1.zip' and I'm able to add to to the vDS, but when I connect the uplinks and migrate the L3 Control VMKernel, I get the following error where it complains about the SPROM when the module comes online, then it eventually drops the VEM.

I have tried gracefully removing ESXi-1 from the vDS and cluster, reformatting it with a fresh install of ESXi 5.5u1, but when I try to join it to the N1KV it throws the same error.Hi,
The SET_PORT_STATE_FAIL message is usually thrown when there is a communication issue between the VSM and the VEM while the port-channel interface is being programmed.
What is the uplink port profile configuration?
Other hosts are using this uplink port profile successfully?
The upstream configuration on an affected and a working host is the same? (ie control VLAN allowed where necessary)
Per kpate's post, control VLAN needs to be a system VLAN on the uplink port profile.
The VDC SPROM message is a cosmetic defect

I am looking to design a solution for a customer and they run a very tight hosting environment with Nexus 1000V switches and want to setup private vlans as they are running out of vlans
I need to find some info on if it is possible to trunk a private vlan between 2 nexus switches
Or any info on private vlans on Nexus 1000V
Thanks
RogerHello Roger,
Yes, pVLANs can be trunked between switches. A good discussion can be found here. Have you considered VXLAN as an alternative to pVLANs? VXLAN allows up to 16M segments definied though they differ slightly from pVLAN in that all VMs in a VXLAN segment can communicate.

Private Vlan, Etherchannel and Isolated Trunk on Nexus 5010
I'm not sure if I'm missing something basic here however i though that I'd ask the question. I recieved a request from a client who is trying to seperate traffic out of a IBM P780 - one set of VIO servers/clients (Prod) is tagged with vlan x going out LAG 1 and another set of VIO server/clients (Test) is tagged with vlan y and z going out LAG 2. The problem is that the management subnet for these devices is on one subnet.
The infrastructure is the host device is trunked via LACP etherchannel to Nexus 2148TP(5010) which than connects to the distribution layer being a Catalyst 6504 VSS. I have tried many things today, however I feel that the correct solution to get this working is to use an Isolated trunk (as the host device does not have private vlan functionality) even though there is no requirement for hosts to be segregated. I have configured:
1. Private vlan mapping on the SVI;
2. Primary vlan and association, and isolated vlan on Distribution (6504 VSS) and Access Layer (5010/2148)
3. All Vlans are trunked between switches
4. Private vlan isolated trunk and host mappings on the port-channel interface to the host (P780).
I haven't had any luck. What I am seeing is as soon as I configure the Primary vlan on the Nexus 5010 (v5.2) (vlan y | private-vlan primary), this vlan (y) does not forward on any trunk on the Nexus 5010 switch, even without any other private vlan configuration. I believe this may be the cause to most of the issues I am having. Has any one else experienced this behaviour. Also, I haven't had a lot of experience with Private Vlans so I might be missing some fundamentals with this configuration. Any help would be appreciated.Hello Emcmanamy, Bruce,
Thanks for your feedback.
Just like you, I have been facing the same problematic last months with my customer.
Regarding PVLAN on FEX, and as concluded in Bruce’s previous posts I understand :
You can configure a host interface as an isolated or community access port only.
We can configure “isolated trunk port” as well on a host interface. Maybe this specific point could be updated in the documentation.
This ability is documented here =>
http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/layer2/513_N2_1/b_Cisco_n5k_layer2_config_gd_rel_513_N2_1_chapter_0101.html#task_1170903
You cannot configure a host interface as a promiscuous port.
You cannot configure a host interface as a private VLAN trunk port.
Indeed a pvlan is not allowed on a trunk defined on a FEX host interface.
However since NxOS 5.1(3)N2(1), the feature 'PVLAN on FEX trunk' is supported. But a command has to be activated before => system private-vlan fex trunk . When entered a warning about the presence of ‘FEX isolated trunks’ is prompted.
http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/layer2/513_N2_1/b_Cisco_n5k_layer2_config_gd_rel_513_N2_1_chapter_0101.html#task_16C0869F1B0C4A68AFC3452721909705
All these conditions are not met on a N5K interface.
Best regards.

Heads Up: Private VLAN Sticky-ARP DHCP Issues
Here is the scenario:
Private VLANs are configured on a 6500 Sup720 with SVIs routing for the PVLANs.
DHCP Snooping and IP ARP Inspection are also configured for the PVLAN subnets.
A DHCP Server is offering 3 day leases.
A laptop connects to the network and receives a 3-day lease. The user leaves the office and returns 4 days later. The DHCP server offers a new lease with a different IP address. Furthermore, the previous IP address leased to the laptop has been handed out in a new lease to another host. Both systems receive their DHCP lease but have no network connectivity.
The problem occurs because, by default, PVLAN SVIs use Sticky-ARP and never age out their ARP cache. Since the laptop has a different IP address to MAC address mapping than recorded in the Sticky-ARP cache, a violation occurs and the switch prevents the new IP address from populating the ARP table on the switch.
Sticky-ARP is a security feature that prevents one system from stealing another systems IP address.
Log messages show the following:
%IP-3-STCKYARPOVR: Attempt to overwrite Sticky ARP entry
The 6500 PVLAN configuration guide Restrictions and Guidlines section suggests that Sticky-ARP is fundamental to Private-VLANs, and the only work-around for this problem is to create manual arp entries for the new IP address. This is clearly not a viable workaround for this scenario.
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/122sx/swcg/pvlans.htm#wp1090979
However, the 6500 Command Reference shows that Sticky ARP can be disabled, but makes no reference to PVLANs
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/122sx/cmdref/i1.htm#wp1091738
There appears to be two sensible solutions to this problem:
1) Disable Stick-ARP on the 6500 for the PVLANs. Since DHCP Snooping and IP ARP Inspection are configured, sticky-arp can be disabled without relaxing network security. This is assuming the 6500 will accept the command and will not break the existing PVLAN functionality.
2) Extend the DHCP lease longer, to 45 or 90 days perhaps. This will catch most transient activity and keep the IP address to MAC address relationships the same, wherever possible. The downside here is that DHCP address pools could collect stale entires that would take the lease time to flush, thus reducing the overall available IPs in the pool.
Has anyone else run into this problem? If so, what was your solution? Did you attempt either option above? I am planning on using solution #1 above, but I wanted to ping the NetPro community with this as I am sure we are not the first customer to run into this. Or are we??
Regards,
BradExcellent question.
Sticky-ARP is NOT intended to be a pain-in-the-butt that should disabled right away, rather, it is a security mechanism that prevents a system from stealing an active IP address on the subnet and causing a lot of problems. Sticky-ARP works best on subnets that have all static IP addressing where there is no expectation that a host would frequently change its IP address.
Yes, I would recommend keeping Sticky-ARP on subnets with all static IP addresses.
In DHCP subnets with no static IP addressing, DHCP Snooping and IP ARP Inspection provide the same security coverage that Sticky-ARP does, they prevent a system from claiming an illegitimate IP and MAC address. Furthermore, in DHCP subnets, it is reasonable to expect that a host would change its IP address from time to time when its lease expires.
Sticky-ARP does not provide any addtional securtity benefits when DHCP Snooping and IP ARP Inspection are active and it only causes problems when a lease expires.
When Cisco made Stick-ARP the default behavior for Private VLANs, they certain did not have DHCP in mind.
In Summary, it should be known as a Best Practice that when using Private VLANs on user segments with DHCP that DHCP Snooping and IP ARP Inspection should be enabled and Sticky-ARP be disabled.

Nexus 1000v, VMWare ESX and Microsoft SC VMM
Hi,
Im curious if anybody has worked up any solutions managing network infrastructure for VMWare ESX hosts/vms with the Nexus 1000v and Microsoft's System Center Virtual Machine Manager.
There currently exists support for the 1000v and ESX and SCVMM using the Cisco 1000v software for MS Hyper-V and SCVMM. There is no suck support for VMWare ESX.
Im curious as to what others with VMWare, Nexus 1000v or equivalent and SCVMM have done to work around this issue.
Trying to get some ideas.
ThanksAaron,
The steps you have above are correct, you will need steps 1 - 4 to get it working correctly. Normally people will create a separate VLAN for their NLB interfaces/subnet, to prevent uncessisary flooding of mcast frames within the network.
To answer your questions
1) I've seen multiple customer run this configuration
2) The steps you have are correct
3) You can't enable/disable IGMP snooping on UCS. It's enabled by default and not a configurable option. There's no need to change anything within UCS in regards to MS NLB with the procedure above. FYI - the ability to disable/enable IGMP snooping on UCS is slated for an upcoming release 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.
Regards,

Can a Nexus 1000v be configured to NOT do local switching in an ESX host?
Before the big YES, use an external Nexus switch and use VN-Tag. The question is when there is a 3120 in a blade chassis that connects to the ESX hosts that have a 1000v installed on the ESX host. So, first hop outside the ESX host is not a Nexus box.
Looking for if this is possible, if so how, and if not, where that might be documented. I have a client who's security policy prohibits switching (yes, even on the same VLAN) within a host (in this case blade server). Oh and there is an insistance to use 3120s inside the blade chassis.
Has to be the strangest request I have had in a while.
Any data would be GREATY appreciated!Thanks for the follow up.
So by private VLANs, are you referring to "PVLAN":
"PVLANs: PVLANs are a new feature available with the VMware vDS and the Cisco Nexus
1000V Series. PVLANs provide a simple mechanism for isolating virtual machines in the
same VLAN from each other. The VMware vDS implements PVLAN enforcement at the
destination host. The Cisco Nexus 1000V Series supports a highly efficient enforcement
mechanism that filters packets at the source rather than at the destination, helping ensure
that no unwanted traffic traverses the physical network and so increasing the network
bandwidth available to other virtual machines" -

Nexus 1000v VEM module bouncing between hosts
I'm receiving these error messages on my N1KV and don't know how to fix it. I've tried removing, rebooting, reinstalling host B's VEM but that did not fix the issue. How do I debug this?
My setup,
Two physical hosts running esxi 5.1, vcenter appliance, n1kv with two system uplinks and two uplinks for iscsi for each host. Let me know if you need more output from logs or commands, thanks.

Nexus 1000v repo is not available
Hi everyone.
Cisco Yum repo for nexus 1000v is not available at the moment. I am wondering, is it Ok and Cisco finished it experiment with free Nexus1k or I need to contact someon (who?) to ask him to fix this problem.
PS Link to the repo: https://cnsg-yum-server.cisco.com/yumrepoLet's set the record straight here - to avoid confusion.
1. VEMs will continue to forward traffic in the event one or both VSM are unavailable - this requires the VEM to remain online and not reboot while both VSMs are offline. VSM communication is only required for config changes (and LACP negociation prior to 1.4)
2. If there is no VSM reachable, and a VEM is reboot, only then will the System VLANs go into a forwarding state. All other non-system VLANs will remain down. This is to faciliate the Chicken & Egg theory of a VEM being able to initially communicate with a VSM to obtain its programming.
The ONLY VLANs & vEth Profiles that should be set as system vlans are:
1000v-Control
1000v-Packet
Service Console/VMkernel for Mgmt
IP Storage (iSCSI or NFS)
Everything else should not be defined as a system VLAN including VMotion - which is a common Mistake.
**Remember that for a vEth port profile to behave like a system profile, it must be define on BOTH the vEth and Eth port profiles. Two factor check. This allows port profiles that maybe are not critical, yet share the same VLAN ID to behave differently.
There are a total of 16 profiles that can include system VLANs. If you exceed this, you can potentially run into issues with the Opaque data pushed from vCenter is truncated causing programming errors on your VEMs. Adhering to the limitations above should never lead to this situation.

Robert -
Cisco Nexus 1000v stops inheriting
Guys,
I have an issue with the Nexus 1000v, basically the trunk ports on the ESXi hosts stop inheriting from the main DATA-UP link port profile, which means that not all VLANS get presented down that given trunk port, its like it gets completey out of sync somehow. An example is below,
THIS IS A PC CONFIG THAT'S NOT WOKRING CORRECTLY
show int trunk
Po9 100,400-401,405-406,412,430,434,438-439,446,449-450,591,850
sh run int po9
interface port-channel9
inherit port-profile DATA-UP
switchport trunk allowed vlan add 438-439,446,449-450,591,850 (the system as added this not user)
THIS IS A PC CONFIG THAT IS WORKING CORRECTLY
show int trunk
Po2 100,292,300,313,400-401,405-406,412,429-430,434,438-439,446,449-450,582,591,850
sh run int po2
interface port-channel2
inherit port-profile DATA-UP
I have no idea why this keeps happening, when i remove the manual static trunk configuration on po9, everything is fine, few days later, it happens again, its not just po9, there is at least 3 port-channel that it affects.
My DATA-UP link port-profile configuration looks like this and all port channels should reflect the VLANs allowed but some are way out.
port-profile type ethernet DATA-UP
vmware port-group
switchport mode trunk
switchport trunk allowed vlan 100,292,300,313,400-401,405-406,412,429-430,434,438-439,446,449-450,5
82,591,850
channel-group auto mode on sub-group cdp
no shutdown
state enabled
The upstream switches match the same VLANs allowed and the VLAN database is a mirror image between Nexus and Upstream switches.
The Cisco Nexus version is 4.2.1
Anyone seen this problem?
CheersUsing vMotion you can perform the entire upgrade with no disruption to your virtual infrastructure.
If this is your first upgrade, I highly recommend you go through the upgrade guides in detail.
There are two main guides. One details the VSM and overall process, the other covers the VEM (ESX) side of the upgrade. They're not very long guides, and should be easy to follow.

http://www.cisco.com/en/US/docs/switches/datacenter/nexus1000/sw/4_2_1_s_v_1_4_a/install/vem/guide/n1000v_vem_install.html
In a nutshell the procedure looks like this:
-Backup of VSM Config
-Run pre-upgrade check script (which will identify any config issues & ensures validation of new version with old config)
-Upgrade standby VSM
-Perform switchover
-Upgrade image on old active (current standby)
-Upgrade VEM modules
One decision you'll need to make is whether to use Update Manager or not for the VEM upgrades. If you don't have many hosts, the manual method is a nice way to maintain control on exactly what's being upgrade & when. It will allow you to migrate VMs off the host, upgrade it, and then continue in this manner for all remaining hosts. The alternate is Update Manager, which can be a little sticky if it runs into issues. This method will automatically put hosts in Maintenance Mode, migrate VMs off, and then upgrade each VEM one by one. This is a non-stop process so there's a little less control from that perspective. My own preference is any environment with 10 or less hosts, I use manual, for more than that let VUM do the work.
Let me know if you have any other questions.

Port-channel with Private VLANs on Nexus1000v
Hi all,
It says that private vlans are not supported on port-channel ports ont Nexus 1000v L2 Switching Guide.
AFAIK, if you have two ports between ESX VEM and physical switch and both these ports are configured as 802.1Q and carrying the same VLANs, when the port which carries the traffic at the moment fails, the other port do not failover automatically. This is mentioned in "Nexus 1000v Deployment Guide version 2" as ,
"Individual Uplinks : A standard uplink is an uplink that is not a member of a PortChannel from the VEM to a physical switch. It provides
no capability to load balance across multiple standard uplink links and no high-availability characteristics. When a standard uplink fails, no secondary link exists to take over. Defining two standard uplinks to carry the same VLAN involves the risk of creating loops within the environment and is an unsupported configuration. Cisco NX-OS will post warnings when such a condition occurs. "
Does anyone have any idea in order for the attached topology to work. Do I have to forward each and every VLAN from different ports ? If I do that how am I going to manage different VLANs and still have that hosts in the same primary VLAN with same IP subnet ?
Thanks in advance.
DumluHi,
You can't have M and F ports in single port channel irrespective what code version you are running , it will throw error on you..
nor you can have m1 port channel one side and another f port channel other side , port channel
