• Issue of private VLAN

  Hello

  I want to configure private VLANs on cisco switch science I write this command (host of the private vlan switchport mode) on the interface automatically interface to go down, please help me

  I'm not sure that the 3560 supports VLAN private dashboard, but it supports the ports protected with "protected" switchport mode

  Here is the guide on this feature.

• Switches 2950 with private - vlan

  Hello experts!

  Do you know if switches 2950 private vlan suport? I have updated to IOS and try to configure PVLAN, but this model of switch is not the interface mode command "switchport private - vlan".

  Best regards

  Rodrigo has.

  2950 supports onboard PVLAN don't, which differs from the private VLAN.

  The following link has the support matrix for pvlan on all Cisco switches.

• VMotion: A large private VLAN or several small VLAN for each cluster?

  Our production of VMware ESX 3.5 environment begins to develop very quickly and since we have different subnets 1,000001 million (bad network design), but all our esxHost Service Console is on the same subnet for accessibility, it would make sense to have VMotion all the different of the pole on a large local network separate VIRTUAL private or private VLAN?

  We currently have 3 clusters running in our production environment, with each cluster serving a different subnet for connections to data and mgmt VMs.  These 3 groups all are currently 3 separate private LAN of VMotion.

  Over the next month we will add an extra 2 groups serving two different subnets.

  So my question is, how is another to tackle this task?  You create a new VLAN separate private for each cluster (which is what we are doing now)?  Or you have created a large private VLAN for VMotion?  If you have created a large private VLAN, what problems met?  Performance problems?  Networking issues?  Collisions of data?  All esxHost panic?  SMV panic?

  Your comments on your experience would be greatly

  appreciated!

  Hello

  I did have problems with a large network of VMotion. Or with cluster of specific networks of VMotion. Note that with VLAN possible external of attacks using the VLAN is a matter of trust as the VLAN do not guaranttee security.

• Question of vlan SG200 (ESXi VSA config)

  Hello! I have three switches SG200-26, and I have also two hosts ESXi I want to connect exactly as shown on the attached map of 'best practices' by VMware.

  

  Even if I created the VLAN in the SG200 and I put the two VLANS (508 and 608), as authorized these ports (where my ESX NIC are connected), I can't host ping host 1 2 when the configuration of their NETWORK interface card to use 608 VLAN.

  Am I missing something? My IP is all in the 192.168. network and the only reason for which I need a VLAN is to separate the traffic of the VSA backend internally, only these two hosts will use the VLAN. So I think that I don't have to create virtual interfaces on my router because this is the case, is my understanding correct?

  Also sending my switch config screenshot below... 3 switches all have the latest firmware.

  

  Any ideas what to change to make it work on the SG200 would be appreciated!

  VMware also has that Protocol VLANS on the physical switch must be 802. 1 q, not of ISL, someone knows which one uses my SG200-26?
  In addition, the only requirements is that my two hosts:

  • Are in the same subnet.
  • Have static IP addresses.
  • Have the same default gateway configured.

  Thank you for your time!

  Alex

  Hi Alex,

  My switch supports 802. 1 q, your config switch seems ok at this point.

  Here are some of my thoughts that I see the announcement and I'm a bit confused.

  What worries me is the configuration on the wall of sound, or the router, they are not spread of VLAN between ports on the router?

  • You're not VLAN 508 multiplication and 608 via the router, so I guess you have two network interfaces on the router, one for each of the two switches as shown in the first diagram... You can expand on the description of the network configuration of the router.
  • You are using two NICs for each host and spreading with tag vlan packets for VLAN 508 and 608 of each NETWORK card?  But the pattern of reference would indicate that you have four physical network interface cards to each HOST.
  • If so, I suppose that HOST servers are connected with the GE15 and switch 3 and GE16 and GE2 GE3 switch 1

  Nope, I want to talk to you, please send us your phone coordinated with this validation URL

• Trunking VLANS on ESXi 5

  I play with a test environment and want to configure servers on several different VLAN. The problem is that I have only 2 network ports on my test server. It is plugged into a Cisco 3500 switch. Can I enable trunking and it will allow me to install servers on different VLAN? I'm a bit confused on the Setup on the ESXi. I have install a vswitch and keep the VLAN ID 0 or all?

  I know how to set up the side the equation with dot1q trunking Cisco, but if I setup 2 adapters, I set them as a port channel group or let them trunking separately? Can you do both to increase flow? If I do that, should I change anything on the side of ESX?

  Sorry for the stupid questions, just want to do things the first time.

  Hi, welcome in the community.

  All you need to do is to set up several groups of virtual computer on your vSwitch ports to meet all tags VLAN that you plan to use.

  See my walkthrough with screenshots on this thread;

  http://communities.VMware.com/message/2140869#2140869

  Once you have deployed your guest virtual computer, you will be able to select the network in the drop-down list. Simply right click and change the settings for the virtual machine, select network, dropdowd of network connection card (choose the label - name them properly)

  See you soon,.

• VLAN Trunking ESXi with blade HP c7000 and Juniper EX3200

  Hi, I'm quite new in VMWare field, because recently my company is going to launch a public cloud in Malaysia, his will combine several technologies, so I guess I have no choice but to go and study all materials and related software. My background is system and network, I understood the concept and success raising (EX3200) switch with port is lucky trunking with id vlan native 48, where my other vlan is 45-47. However later on, I will consider how I need to activate multiple markup in ESXi, I found this VST it one that I seek, I created VLANs inside the vSwitch. Then I change my machines in vlan respectively (label to change card). Then I change connect it outside (adapter for vMotion and multi-service, call Management Network default console) to vlan 48, however, when I change, my blade appear to be isolated from others. I remove id vlan, or put as 4095, then it works again, but the machine all connect them my VLAN (45-47) can not ping to the outside, please help me in this...

  Yes do not activate the switch with VLAN, vlan 48 which is native on the trunk port create a portgroup of vmware on the vswitch who has network you cards connected to the switch but leave the tag of vlan empty this will be then in the vlan default of the switch, and then create three more vmware exchanges one for each vlan and this time make sure you enter the id vlan.

  then provide that the routing has been implemented each vm will be able to talk to each other (if there are now firewalls to stop).

• VLAN and ESXi 3.5 U3

  At home, I have a DL380 G4 with ESXi on it

  what I want to do is to create a trunk dot1Q to a cisco 2960

  I want to do 6 7 maybe Vswitches with a tag of vlan diferant

  IE (Vswitch 1 to vlan 1 and put only the management of the interface on this vswitch)

  then create VM I want is maybe on other VLANs (for example if I want to have a virtual machine directly on the internet, I would be able to use vlan 7 and not worry that someone could hack into the host or any other virtual machine)

  can do this and how?

  also I want to the team or etherchannel 2 network cards

  If you create switches 6, or 7, you would need 6 or 7 physical network adapters, because you can't share a physical nic between vSwitches. I suggest to create 1 vSwitch with multiple exchanges, you would be able to define a vlan to each portgroup. If you add two network cards in the vswitch containing exchanges you also redundancy!

• Edge of private VLAN / protected Port

  Hello!

  I have question about the Ports protected on Dell Powerconnect 6248.

  What I want to achieve - two devices, one connected to the port39 and the other at 40 cannot talk to each other. I assumed that this can be done forwards with function "protected Ports."

  So I created:
  switchport protected name 0 "a."
  protected switchport 1 name 'B '.

  interface ethernet 1/g39
  switchport access vlan 3
  switchport protected 0
  output
  !
  interface ethernet 1/g40
  switchport access vlan 3
  switchport protected 1
  output

  Some tests: connect a device with IP 192.168.7.10 (random IP local IP address range) at port39 and another device with IP 192.168.7.11 to port40. When I perform PINGs these devices can ping each other.
  What's wrong with my configuration or "Protected Ports" works in a different way?
  And why are there groups (in the example, I created A and B)-in manual I can't find any explanation thereon.

  Did some testing on that, and we were able to get it to work as you described where they are unable to ping to another. You will need to do is to place the ports in the same group. If 39 and 40 ports will need to be placed on the same group and then they should not be able to communicate with each other.

• Sending a network private VLAN virtual

  We have a situation where we have 2 server company that are geographically separate cluster.  The clustering software will not work unless one of the connections on both servers is on the same network segment.  I was informed by the seller that it has been accomplished in the past via a VIRTUAL LAN.  Is it possible to send one VLAN via a VPN IPSEC encrypted using an ASA 5510?  If so, how it is and how this address would be announced on?  I know it's kinda a complicated question, so thanks in advance for the effort.

  It is not possible, one VLAN is set on layer2 tunneling ipsec encrypts IP packets and therefore operates in Layer 3. You need switching tehcnology to do this, such as dark fibre, or EoMPLS, if you have an mpls connection between your sites. You could focus on L2TP, might be able to do what you have to, but in my opinion, it is not available in new versions of asa > 7.x

• VSwitch routing: private VLAN to make public, communicate

  How to configure ESX 3.5 to: make two LANs, a public network on (using DHCP) and the other a private LAN (192.168.x.x). do this without using any physical router? Thank you in anticipation

  Your right I did had not bother to check license status since I use out in the test CA.

  You can check out their web page in the link provided.

  You could create a VM with IPCOP, Shorewall or any Linux variant with appropriate routing and iptables rulesets.

• Build a private network between two physical hosts in ESXi 4.0 for VM guests

  Hi all

  I am a newbie in the use of VMWare ESXi for my company testings and I have a question on networks

  in ESXi. In fact, I always do my tests in my VMware Workstation, and it's pretty easy to build a virtual

  private network between two guests of computer virtual and it needed to do more real testings on ESXi environment.

  But now I have two Dell servers mounted and with two ESXi 4.1 installed on these servers.

  Each server has two network cards connected to the same network switch.

  In this essay, I have to install a RAC Oracle 11 g as guests of virtual computer on two separate server Dell for

  two RAC nodes.

  The installation Guide for the PAP, I need to build a network between two nodes.

  My superficial knowledge network, the private network address is not the same as

  the public network address, in this case, the IP address provided by the network switch is

  10.1.10.X and it should be public network address.

  In this case, how can I do the private network of ESXi settings?

  I do the settings of the network switch? I'm not the guy of networking and really

  want your expertise in this area.

  If you have an idea or experience to share, please kindly help.

  Thank you very much

  Yes, that's correct. It would have made you have a private network layer 3 between the two guests in the 192.168.1.x address range.

  In general, you also want to isolate a layer 2 (ethernet) with the VLANS on the physical switch, but if this is not possible at this time then it could be implemented now and you could later add VLAN in the switch.

  It is also the reason why I think you should create a new portgroup on the same vSwitch as other existing exchanges. If you later configure VLAN to the physical switch, it will be very easy to activate this on the "private" portgroup

• VPN site-to-site-1 ip private 6 subnets of vlan

  My firewall is a Cisco ASA 5520 8.4 (5) running.

  I have to install a tunnel vpn site-to-site between a private ip address and 6 private subnets. I work with another engineer on the other side.

  private - external ip address static public ip<------site to="" site-----="">outsite static public ip - 6 private VLAN.

  Each VLAN must be able to get to the private ip address and vice versa. I'm trying to understand what would be the best configuration.

  Any suggestion would be appreciated.

  Thank you

  Carlos

  I think that there is no configuration 'best' just a configuration that should work:

  On your ASA set up the VPN with a crypto-ACL as follows:

  the object PRIVATE IP network

  host 10.10.10.10

  network to NETWORK-VPN-REMOTE object-group

  object-network 10.100.1.0 255.255.255.0

  object-network 10.100.7.0 255.255.255.0

  object-network 10.200.1.0 255.255.255.0

  ...

  !

  VPN - XXX access list permit ip object object-group PRIVAT-IP NETWORK-VPN-remote CONTROL

  !

  card crypto VPN 10 corresponds to the VPN - XXX address

  On the other side, the crypto ACL must be exactly in the opposite direction. And you have to exempt NAT traffic.

• ESXi and VLAN

  Hello

  I am facing a problem that you are trying to use VLANs in Esxi. Here's the scenario.

  A HP Blade as host.

  A HP GbE2c Ethernet blade switch.

  Allied Telesis switch connect the box to the network.

  Vlan1 - 192.168.1.0/24 (5 VM).

  VLAN2 - 192.168.2.0/24 (1 VM).

  5 virtual machines residing in the VLAN1 use vSwitch0 in a portgoup named VM network VLAN ID 0. The virtual machine in the VLAN2 uses vSwitch0 in a portgroup named VLAN2 with VLAN ID 2. The port in the Ethernet switch of the blade where the Esxi host is connected is labeled for VLAN 1 and 2 to pass. Also link ports Allied rising connection with switch blade are also marked for both VLAN.

  I'm doing something wrong? As soon as I change the connection port to the Esxi host to the switch blade for the tag, I lose the connections with all virtual machines (MY PC is in VLAN1 connected to the Allied switch).

  Thank you

  Can you change the VLAND 1 in vSwitch (port network VM group)

• Oracle 10g RAC - private interconnection on VLAN not routable private

  There is in our data center existing Oracle 10g RAC configured with VLAN private interconnection managed by a different group of DBA.
  
  We create a new, separate Oracle 10 g RAC environment to support our request.
  
  When we discussed with our data center people to set up a local VIRTUAL private network for our CARS of interconnection, they suggest to use the same VLAN used by the other Oracle RAC configurations existing private. In this case the IPs of interconnection will be on the same subnet as the other Oracle RAC configurations.
  
  For example, if
  RAC1 with 2 nodes use 192.168.1.1 and 192.168.1.2 in the VLAN_1 for the Interconect, they want us to use the same VLAN_1 with interconnecting IP 192.168.1.3 and 192.168.1.4 to our 2 node RAC.
  
  Share the same subnet on the same private VLAN for the interconnection of different configurations of RAC, supported?
  Which will cause a drop in performance? This means the IPs of a RAC interconnect configuration is to pings from other RAC configuration.
  
  Someone met with such purpose?
  
  Could not find any info on it on Metalink.
  
  Thank you

  Yes
  It is practically very doable... as you would have only 4 m/c in subnet ip... and it is much less than the public subnet that we should abstain from interconnection.
