I was seeing a problem where on two different ESX hosts, VEM card show the same UUID. Because of this, when module gets inserted in VSM, they tried to take over each other's slot. This caused network disruption. I tried setting UUID manually to match...

Three questions on Nexus 1000v for the brains in this forum:First, the 4.0(4)SV1(1) documentation, all N1Kv design guides, and the Nexus 1000v training curriculum all hammer home the point that packet, control, and management must be different VLANs....

Looking for a concise Nexus 1000 deployment guide.

Could someone please have a look at my config to see if it looks correct?  Eventually I will have two upstream 3750's.  4 NICs to each.  I didn't show the second port-channel config.  Thanks for any help.

I ask a lot of questions on here....Was at the same site as my other question about the trunk ports.  Their environment is three separate networks.  Internal is a 3750 switch stack.  DMZ1 is a single 3750, and DMZ2 is a single 3750.  None of these ar...

As part of our testing, I published two new port-profiles for one of our vSphere hosts to use. The one profile carries our VMotion, SC/Mgmt, Control, Packet, and Guest traffic. The second uplink contains simply the iSCSI network. The objective was to...

So I've read all the articles on Cisco.com to the best of my ability and wondered if this is at all possible?I would like to install the VSM, attached it to the vSwitch (per the documentation).Currently all Guest VM's connect to the vSwitch.Install t...

Trying to find detailed QoS information for the Nexus 1000V, I’ve looked at the QoS configuration guide, but it lacks some detail around how to prioritize the service console and VKernel traffic.  Do you have any whitepapers or best practice docs tha...

Hi everyone,We've been working through and managed to get our 3 vSphere servers onto the N1KV. What our server team has noticed is that if we restore a 20 gig image of a server from iSCSI when iSCSI traffic is on one NIC (vSwitch was the test for thi...

First off, thanks everyone who has answered my small barrage of questions lately, both on and off-line. We've really been making progress in our N1KV rollout and it's much appreciated.Hopefully this one is an easy one. I was reading the 1000v product...

I'd like to know if anyone has  successfully configured LACP on 1000V? I'm having problem with LACP  where etherchannels are not establishing. If I don't use LACP, and turn  on etherchannel unconditionally, then it works fine. My 1000v is  connected ...

We've had some real issues at this site getting the 1Kv up.  We were on the phone with TAC for hours yesterday with other issues (one turning out to be a bug)...  For the most part everything is going well today, except one thing.  When I roll a serv...
