Cisco Application :: 1000v Connection With VCenter On Same ESX Host

Dec 21, 2012

In my lab I have only one ESX server.  On this server I am running VSM and vCenter (appliance).I am trying to get 1000v working however everytime I try to migrate my ports I get the following error:Network configuration change disconnected the host '' from vCenter server and has been rolled back.fault.NetworkDisruptedAndConfigRolledBack.summaryIt seems that it doesn't like the fact that vCenter lives on the same ESX host as I'm trying to migrate. How I could get this to work?

Cisco Application :: Requirements For VCloud Director 1.5 And Nexus 1000v

Oct 3, 2011

According to the note at the bottom of a VMware KB Article "Cisco Nexus 1000V and VMware vCloud Director 1.5,"

"Note:  You are must use the Cisco Virtual Network  Management Center (VNMC)  virtual appliance from Cisco. This is a  separate products and needs to  be licensed from Cisco."

Is this actually the case? I know you could use portgroup based network  pools with vCD 1.0 and 1kv. Can I use the 1kv with VLAN-backed network  pools in vCD 1.5 without the Virtual Network Management Center or is it  required?

Cisco Firewall :: 755629 / VNMC To VCenter Integration

Mar 21, 2013

After integrating vCenter with VNMC I see the ESX hosts that exist on vCenter on VNMC ResourceManagement>Resources>VirtualMachines, but I cannot see any of the VM's that exist on on each of the ESX hosts.Yet, the integration is so straightforward that I have no idea why I'm not getting VM information.Then obviously I cannot match any of the VM attributes on VSG for vZone creation for instance.What can I do to troubleshoot this? VNMC version is 2.0(3)f, vCenter is on 5.0.0 build 755629

Virtual PC Using Different Internet Connection Then Host?

Feb 2, 2011

Running a Windows 7 laptop plugged into a LAN using ethernet cable with internet.The built-in wireless nic on the laptop connects to a totally different internet network. I set up an XP Mode Virtual PC on the laptop with the intention that it would use the wireless internet connection.I set this up by installing Microsoft Loopback Adapter, then sharing the wireless nic to it. The Virtual PC is set to use the Microsoft Loopback Adapter as its network connection.My problem is that only the hard wired internet connection works.The wireless is connected and has an ip address, however no traffic flows through it until i either disable the cabled network or physcially unplug the cable. Is it possible to have my host laptop use the cabled internet connection and my virtual pc use the 2nd wireless internet?

Cisco Switching/Routing :: 1000v VEM Not In VSM?

Feb 9, 2012

have a single host that refuses to register his VEM in VSM, I can see him in show svs neighbors and all other servers went in although a couple of them we had to do more than once but I have all indications it is working, have correct license, sees him, pings him, everything looks fine but from timeto time just get the message:
N1KVSM-B# 2012 Feb 10 15:45:32 N1KVSM-B %VMS-5-DVS_HOSTMEMBER_INFO: A host with  name=[ky-dc1-esxi13.cajones.local] and  uuid=[00000000-0000-0000-8000-0025b5010019] is added to the dvs. The host is not  found  as a module in the VSM configuration
  So I even added him to the VSM configuration statically as VEM 7 the next available and nothing.

Cisco :: Enable SNMP Traps On Nexus 1000V?

Dec 18, 2011

I want to configure snmp-traps regarding stpx (root-inconsistency, loop-inconsistency) on a Cisco Nexus 1000V. The command "show snmp traps" lists stpx as a trap that could be configured and which is not at the moment.
MKBE1NX1# sh snmp trap
Trap type                                           Enabled
entity               : entity_mib_change               Yes         
entity               : entity_module_status_change     Yes         
entity               : entity_power_status_change      Yes         

Nothing about stpx... Is there some other way to configure more traps?

Cisco Firewall :: ASA 1000V And ASA 5500 Migration Between Firewalls

Jul 8, 2012

We currently have redundant FWSM's and are planning a migration to standalone ASA 5500 series firewalls. However, we have a complete VMWare environment and are looking at the Nexus 1000V. I understand the Nexus 1000V and VSG architecture and implementation, and I do understand that the ASA 1000V is designed for cloud environments. But I do have one question about the ASA 1000V.
Is it possible for an ASA 5500 series firewall to be replaced by an ASA 1000V? Basically, can an ASA 1000V be a sole firewall solution, or are ASA 5500's still needed? Is there a datasheet anywhere that compares the ASA 1000V and ASA 5500 series?

Cisco Switching/Routing :: Nexus 5000 Esx Host Lose Connection To Net-App SAN For 10-16 Seconds

Dec 4, 2011

I have two 5000. Uplinks are Vpc to nexus 7000 and downlink are connected to Esx host. When I reboot one 5000, some Esx host lose connection to the NetApp SAN (Iscsi and CIFS) for 10-16 seconds. This is enought to generate errors and event corruption on disk. The 10-16 blackout occur when the switch as reloaded.
My theory is that VPC interface comme up 10-16 seconds after the edge interface(ESX). This create a blackhole effect for ESX host.

Cisco Switching/Routing :: Nexus 1000v Don't Use Private VLANs

Aug 28, 2012

We have a requirement for private VLANS for DMZ hosting within one of our datacentres. I just want to query how private VLANs would work in our environment.We have physical servers connected to fex ports (2 fex per rack for each 5k) of a 5548UP switch, virtual servers using the nexus 1000v (vmware hosts connected to fex ports) Out firewalls and load balancers are connected to an upstream pair of nexus 7ks using vPCs.My question is this, ordinarily the firewall would be in a promiscuous port but as these reside on a physically separate switch will the normal vPC trunk still be sufficient or would the "switchport mode private-vlan trunk promiscuous" be required on the vPC up to the northbound 7k.As these connections are already in production I do not want to affect the existing traffic that doesn’t use private VLANs.

Cisco Infrastructure :: Installation Of Nexus 1000v 4.2.1.SV2.1.1 - Operation Timed Out

Nov 6, 2012

We are trying to install the latest version of Nexus 1000v to ESXi5.1 and the installer application is much better than the previos one, but we are having problems with implemetation, because deploying of OVA file times out.
First attempt: Nexus-1 was successfully deployed on ESXi-1, but Nexus-2 which should be deployed on ESXi-2 returned an error: "Deploy OVF template":"Operation timed out." Second attempt: Deploying of Nexus-1 returned the same error Third attempt: The same as the first attempt.
It looks like that there is a time limit which is used for deploying OVA file and since file needs to be uploaded to ESXi it takes too long, so the installation fails. Is it possible to extend this time?

Cisco Application :: ACE4710 TCP Connection Reuse

Jun 8, 2011

We have a rather strange issue, and I'm not sure it's really a problem with the ACE or not. We created an HTTP parameter map called "TCPreuse" and applied it to a virtual server. A show conn detail displays "[ conn in reuse pool : FALSE]" for all connections pertaining to this virtual server. The rserver in question is Linux(Ubuntu) + Apache.Next we applied the HTTP parameter map to another virtual server - this time IIS7 + Windows Server 2008. There are plenty of entries "[ conn in reuse pool : TRUE ]" when I do a "show conn detail".What could the web servers be doing differently that would cause the connection reuse to work on one virtual server and not the other?
