Issue of private VLAN

Similar Questions

• 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.

• 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.

• Private VLAN on ESXi 5.1

  We had ESXi for over a year; standard networking is very well.

  But for testing small virtual machines, I wish I could assign IPs private at will (192.168.x.x) and to communicate beyond the host.

  I created a VLAN with an ID on a standard switch but how do their itinerary outwardly by a IP address?

  It's the virtual routers with DHCP built-in VMware, and if not, what people use?

  I used m0n0wall previously - enough lite and OK for Setup - http://m0n0.ch/wall/downloads.php.  You can import the image of VMware with VMware Converter and this is an installation guide - http://aldosoft.com/docs/m0n0wall-getting-started.html.

  For the virtual machine itself you will need to configure 3 virtual network cards.  When you start m0n0wall I'm sure vmnic0 would be the LAN / WAN interface vmnic1.

• 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.

• Issue of private in the OS 5

  Hello

  In my application, I need to open a url in the BB browser. I use private like this:

  Private private = Browser.getDefaultSession ();

  browserSession.displayPage ("http://www.google.com");

  browserSession.showBrowser ();

  Under the wi - fi connection, this code runs as expected in Blackberry Torch (OS 6), but fails under Blackberry "BOLD" (OS 5). In the latter case, the browser opens, but fails to connect and view the error dialog.

  Is there something I'm missing?

  Try the following:

  From the home screen

  Click on options (key icon)

  then Advanced Options

  then the browser

  What is the configuration of the default browser?

  Change cela at the Hotspot browser and try again.

  That said, the test that you do is not really representative.  If you want to test your code you savages better test in a real work of Blackberry wouldn't you?

• 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.

• 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.

• 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.

• SFE2000 and VLAN

  Before we begin, I want to say that I saw "' responses to my question, but never exactly what I'm looking for, so I create a new post.  I'm not a network engineer, so please forgive my ignorance.

  We are a public library.  We have a network that includes a number of branches, through the central site of the main library.  We show an ASA firewall. We have a Cisco3825 for local and a series of Cisco2800 Internet connection.  We use a system of 192.168.xx.xx, using DHCP network.  We have a number of PCs that are on the network access to the public and they are locked by using various software that prevent people to do much except get Internet.

  What we want to do is to put the public pc in their own network, always using our Internet connection, but not allowing them to see or access one of our 192. addresses.

  We bought a Linksys SFE2000 and it is my understanding that if I use it as a layer 3 switch, we can do what I suggested above.  However, I get so far and I reached my level of incompetence!  We want that all the public pc to come through the SFE2000 and although about allowing the public to use a wireless connection (but that is located).

  Can anyone offer suggestions or point me to a site that will help me?  Thanks in advance and again, sorry for my ignorance.  I look forward to hearing from anyone.

  Well, the router must have at least one interface. If the interface is used otherwise you can simply run it through the router as well.

  If you want to use the features of the ESF L3 basically configure you the VLAN as I've mentioned before. You enable L3 on the ESF, then you configure filtering on the ESF for the VLAN 'public '. Drop everything that goes in your charge of private VLAN.

  The problem is the connection to the router. We must define a new IP subnet for routing between the CPE and the Cisco. So, basically you will need a 3rd VLAN to connect with the Cisco. You can use a very small for this IP subnet if you wish. For example, add VLAN3 with IP address 192.168.99.101/255.255.255.252. The port on the Cisco configure IP address 192.168.99.102/255.255.255.252. On the ESF, set the default gateway 192.168.99.102. Who should route all internet traffic to the Cisco.

• VLAN real PowerConnect base for beginner who does not understand the trunks etc.

  I have several switches Dell powerconnect 3548 and 5548 deployed on my network to install multi that I'm managing their individual DNS names.  now, I've added a voip phone system that works on my network, but to a range of ip addresses completely different to another server.  So, I want all my switches divided into 2 VLANS.  The basic vlan 1 will always manage the switches and all ports and the vlan voip will have its own set of ports on the second VLAN.

  There is no visibility between the VLAN, just different IP addresses different server DHCPd, s so if your clogged in the vlan 1 are you a PC/printer/etc with your own default gateways defined by the field.  If you are connected to one vlan 10 you are a phone and you will get your information from an edgemark server somewhere else.

  so step by step (if you want to give me even better orders) I have actually need it to configure to create a vlan separate and independent who will seek dhcp by an existing voip to its home network device to, while I can still manage my management ip switches.  I understand not all the vocabulary of trunking and I don't know if it needs anything else including marking, because are is all autonomous.  I guess I need a guid for Dummies at vlanning powerconnects.

• Assignment of VLANS by MAC address on a 6248

  Hello

  We have a mixture of 5548 and 6248 switch batteries, all updated to the latest fw, grouped on a 8024f.

  We add 560 Polycom phones to our network and want to assign phones to the voice VLAN and use the internal switch on the phone to the computer workstation.

  The 5548 have the handy table YES, the:

  VLAN voice Yes-table add 00907 Polycom/Veritel_phone___

  It works a treat and the assignment of VLANS for phone and PC works beautifully on the 5548.

  However, the 6248 legacy does not have this feature.

  Am I right assuming that we cannot assign addresses MAC Polycom-issued to one VLAN specific on switches 62XX as 55XX switches on? We are left with assigning simply labeled the voice VLAN? I'm afraid non-voix tag traffic for some applications will be treated badly as voice.

  What is the best way to do it? Here are the General config we will stop for the 6248:

  Configure
  database of VLAN
  VLAN 10 100

  interface vlan 10
  name "VoIP."
  output

  interface vlan 100
  name 'data network '.
  Routing
  IP 10.1.10.1 255.255.255.0
  output

  Example config for a switchport with Polycom and PC phone
  !
  interface ethernet 1/g1
  switchport mode general
  switchport General pvid 100
  No switchport acceptable-framework-type general tag only
  VLAN allowed switchport General add 100
  switchport general allowed vlan add 10 tag
  switchport vlan allowed General remove 1
  output
  !

  The 6248 uses a Broadcom firmware and the 5548 uses a Marvell firmware, that's why we see the differences in the characteristics. The 6248 has no YES table as the 5548. Here is the basic configuration of VLAN voice on the 6248.

  1.

  To start creating a VLAN voice, create it first VLAN database mode for VLAN.

  Console # console (config) # vlan database console(config-vlan) # vlan 2 console (config - vlan) #exit console (config) #.

  2.

  Then, globally enable the Vlan voice.

  Console (config) # vlan VoIP

  3.

  In the configuration of interface for the desired port mode, assign it VLAN to the port using general mode. Then, assign it VLAN voice on the port with the command vlan vlan id #.

  Console (config) # interface console item in gi1/0/10 # switchport general console mode # vlan 2 voice

  There is also this white page that goes over the process.

  www.Dell.com/.../pwcnt_voice_VLAN_support.pdf

  A workstation sends no marked traffic, and will be placed on the general mode port PVID. In this case, it seems that your PVID is VLAN 100, therefore all workstation traffic will go to this VLAN. I'm not aware of a situation where the traffic of the workstation would be confused with traffic voice and placed on the VLAN incorrect, you have a specific situation / application where you think this can happen? I can do some research on this scenario to help alleviate any concerns.

  Thank you

• Communication between hosts in VLAN secondary community

  Hi guys,.

  The guests in the post-secondary community private VLAN is allowed to talk to each other. If there is no port/host set promiscuity, the hosts on the local network VIRTUAL community will be able to talk to each other?

  Or all traffic VLAN number is routed through the promiscuous port?

  FC

  Hey FK,.

  If there is no port/host set promiscuity, the hosts on the local network VIRTUAL community will be able to talk to each other?

  I guess you want to ask if guests in different community VLAN will be able to talk to each other if there is no defined promisc port. The answer is--no, they will not be able to communicate, but they would not be able to communicate, even though the port of promisc was created. Their communication on the port of promisc would be allowed only if the device connected to that port promisc was willing to do routing hairpin - in other words, receive and before a return the same interface package. Generally, you don't want not your different community VLANS to communicate with each other - which is why you created them in the first place - so usually you'd of course that no matter what the device is connected to a port of promisc, there is no routing or is prevented from hairpin burned by an ACL, for example.

  Regarding the mutual communication of the armies as a community VLAN - these hosts will be able to communicate with each other as if it were a VLAN quite normal. The existence or nonexistence of a port of promisc has no influence on that.

  Welcome to ask for more!

  Best regards
  Peter

• Cannot ping hosts on the same vlan on the 2 switches.

  Hey guys so I create my own network in Packet Tracer 6.3. While the hosts can ping others on the same switch 2960 and VLAN, they are unable to ping a host on another switch in the same VLAN. For example. Josh PC on S1 (192.168.10.10) cannot ping PC Doge on S2 (192.168.10.13). I'm sure that they are on the same subnet, so I thing it is a problem of junction...
