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 '192.168.0.10' 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?
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?
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
I have a single cisco 11503 load balancer.There is a single Banner student information system which is load balanced on it with Virtual ip 10.3.20.101 which is working fine without any issues .I am now trying to add an Oracle ERP application with virtual IP 10.3.20.230 and physical ips 10.3.19.22 and 10.3.19.23 all on port 8003.When I just make the group ERP-Apps-Grp active , the vitual ip address 10.3.20.230 is pingable , but when I make the the content Erp_IAT active it stops pinging.

I have a GSS 4490 but only want it to be authoratative for certain hosts. Sysadmins don't want to lose control of their DNS records.How do I point active directory to the GSS to look up the host?I need to keep the AD domain as authorative for the DNS records, but to pass on DNS requests to the GSS for certain hosts.
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?
I have a host that can successfully connect to a PIX 515E (7.x OS) via VPN Client; however, I have no IP routing to the LAN from the remote host.The VPN IP pool works finem,The LAN default gateway is the inside interface on the PIX; the network is flat L2 behind it.The default route on the PIX points out; no other routes are defined,The VPN remote host can be pinged from LAN hosts, but the VPN remote host cannot ping any LAN host, not even the PIX inside interface.
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.
My host has an IP of 184.108.40.206 from a router DHCP. I have a virtual environment which has a DC and DNS and the IP is: 192.168.1.x how can I get access from my host to the virtual environment? What do I need to setup on the host OS? (Windows)
We are using an ASA with 8.4 in transparent mode. Connection fails when a host on inside tries to connect to a server on outside. This server uses mac-address 0100.5E00.0000 to load balance but replies with real mac-address.Firewall logs "Deny TCP".ARP inspection is disabled.
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.
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?
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.
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.
how to add tacacs custom attribute to ACS 4.2 for Nexus 1000V:shell:roles="network-admin admin-vdc"In the interface configuration I've added new service, service - shell, protocol - tacacs+.In the group settings I've enabled this attribute configuration. And it is not works. Default privilege level is assigned to any user with access allowed.
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?
I'm trying to configure VXLAN on 1000v but it not working between two esx.
As I followed the troubleshooting guide on Cisco's website I discovered the following error: Can't get uplink MTU: 4681 Here is the output of the "vemcmd show vxlan-stats ltl 50" command. Port LTL 50 is the VM's port.
vemcmd show vxlan-stats ltl 50 VXLAN Port Stats for LTL 50 Unicast Encapsulations: 0
I've set mtu to 9000 on the UPLINK profile (port-profile) and enabled jumbo frames support on the upstream switch.
According to Cisco, Nexus 1010 can host up to (6) Virtual Service blades. I can't find out how many Virtual Supervisor Modules and Virtual Ethernet Modules that make up one Nexus 1000v switches can be supported by each Virtual Service Blades. In other words, how many Nexus 1000v switches can be created with Nexus 1010 appliance?how to configure Nexus 1000v switches with vmware. without Nexus 1010, the standalone nexus 1000v switches was configured from vCenter as an OVF. But how to configure Nexus 1000v switches with vmware where nexus switches are hosted on Nexus 1010 appliance.
Having problem pinging from Host A on ESX1 to Host B on ESX2. Each host are assigned the same port-profile. If I put 2 host's on the same ESX machine using the same port-profile, they are able to ping each other.

Why do my connection not clear when my service goes to a down state. The only way I can get the connections to clear is by bouncing my content rule. CSS11503 version 08.20.4.05s - SSL all the way to the server --- I also have flow permanent port3 443 configured, but I don't understand why the other two servers go to zero while server01 never goes to zero. If I remove the flow permanent port3 all the counters go to zero, but I would think if the servers goes down then the connections should go to zero regardless of the flow permanent port configuration.

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?
