Edge of private VLAN / protected Port

• VLAN protected port and voice

  When protected switchport is configured on a switchport (3750G switch), is what affects him vlan voice as well? I currently have protected ports configured, but we'll be adding IP phones soon and would prefer not to have to disable ports protected to allow phone phone voice traffic. I found on cisco.com where a port in a vlan voice can be a protected port, but it does not say if the traffic of phones on the switch is blocked or allowed, just that it can be configured on a protected Harbor.

  Thanks for any assistance on this.

  Thank you

  Hello

  By default, all traffic on a 'protected switchport' interface will be sent for the uplinks. This includes all voice traffic and data from this particular interface.

  However, there is a work around available according to your configuration. There is a layer 2 isolation between ports, all traffic to these ports are sent to the uplinks and must be routed from one port to another, even though they may be in the same VLAN. A router is connected to running "proxy arp local' (or local-proxy-arp ip) can respond to ARP requests for IP addresses in a subnet where normally no routing is necessary."

  Depending on the connected device, you can have an able to use the local proxy arp feature to get around this VLAN voice. It should be an L3 device with the available command. 3750's take on support this command.

  Hope this helps

• 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.

• The switch SLM224G does support VLAN per port?

  I'm looking for a simple solution create two LAN. One for my own and the other for my clients, who will be able to use the desktop computer with internet access. I only have one internet connection (ADSL over ISDN) and wil not get another just for my clients.

  My own network should not be accessible or visible to users who use the PC clients. The other way around is authorized, but not really necessary. My setup requires me to connect to the switch to the (ISP) router, and the router has a LAN port not able to do anything related to VIRTUAL networks.

  I read on the VLAN port to put here, where it is stated that creating separate LAN is just the ports in VLANS on the switch, nothing else to do... However, they used a NetGear smart switch.

  I checked SLM224G of Cisco because it is affordable, has 24 ports (instead of 8 for the NetGear) and must support of VLAN. I read a lot about VIRTUAL networks, including:

  «- Means the VLAN per port that you can reconfigure the ports to be in different VLANS.» VLAN per port does not confirm the 802. 1 q supported VLANS.

  -802. 1 q VLAN means you can mark the VLANS with 802. 1 q headers to create a trunk between two devices carrying frames for several VLAN. 802 1 q VLAN confirms that there are also supported VLAN per Port. »

  I knew by the sheets that the SLM224G supports 802. 1 q (tagged) trunking. So it should be, given the text above, also supports VLAN per port.

  My question is if it indeed will support VLAN per port?

  I am able to use it directly behind the router of my ISP and create two separate LAN?

  If so, a supplementary question: how are the PC behind the switch (inside the two VLAN) removes the ISP router IP addresses? It will serve only of the two LAN or do I have to install a DHCP server in the other LAN?

  Any information is welcome!

  Thank you.

  Mr. Bertrand,

  
  

  I read what you posted and I don't think the slm224g will do what your configuration you want to.  The reason behind all this, if you have installed 2 VLAN you will need 2 gateways for each network.  Since then just the ISP router and a network.  I'd get a router capable of VLANs and plug it into the router of the Internet service provider and then you can have up to 4 networks behind your router.  The rvs4000 is a router excellent gigabits, which supports up to 4 VLANS.  So if you need additional ports, you can get unmanaged switches and plug it into the router for added ports.

• Power CLI script to add multiple VLANs with port group name in an ESX cluster

• 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.

• Battery M8024-k (pair) M3048 (pair) battery gal, VLAN and port groups?

  Hi all

  I'm getting more confused by the minute.  I have a pair of M8024-k blade switches in a M1000e enclosure, outside, I have a pair of N3048 switches.

  I think I have the job of stacking on the M8024-k, but I found a configuration guide for Simple mode that says take port 17-20 outside the Group of ports on the pair aggregation and leave the stack ports and internally in the PA Group.  When I do that they remain outside the group, if I do it in the CLI or the GUI.

  Does anyone have a configuration guide that shows how I can pair trunk the 2 together and allow 4 VLAN that I keep coming without access to blade servers inside?  What I get out of simple mode on the M8024-k to achieve?

  Any help gratefully received.

  

  The best source of information is going to be the user guides.

  www.Dell.com/.../manuals

  www.Dell.com/.../manuals

  I would wear the 8024-k off simple mode.

  Console# not simple mode

  On two batteries, you will need to aggregate 4 ports together.  Here is an example to place a port in an aggregation group.

  Console (config) # interface gigabitethernet 0/1/5

  Console (Config-if-1/0/5) # channel-group mode 1 (active / Auto)

  Once the ports are in a channel-group 1, we can then configure the channel group to perform for several VLANs.

  Console (config) # interface port-channel 1

  trunk mode console (config-if-po1) #switchport

  #switchport console (config-if-po1) trunk allowed vlan add 2-150

  This is done, you should have connectivity.

  Keep us informed.

• 1000V - Importance of the ' system vlan "in port-profile

  Hi all

  Can someone help me understand the importance of the command "system vlan" in a profile of port?

  As I understand it, it was used to mark the criticisms of the system VLAN (package, data, etc.) to their config was pushed to vCenter so that they would continue to work the MSM should be down. Is this fair?

  All of the examples I have watch seems to just mark every VLAN (data VM even VLAN) as "system vlan" in their profiles of prot ethernet uplink. Now that is best practice?

  In addition, there is a reason to mark vEthernet with control panel ports vlan?

  See you soon,.

  P

  As you already wear that system vlan is to ensure access to the vlan vsm to go down and then the esxi host is reset. If the system vlan was not enabled host esxi would not be able to talk to the vsm, but this is only the case if the management port using the Cisco VDS and not a VSS or VDS.

  as I mainly use servers with only 2 ports 10 GB I use system VLAN for ESXi management / storage and vMotion and if the vCenter is a virtual machine, then also the vlan that uses. all other VLANS I don't not in the category system VLAN.

  I use also a VSM Layer 3 so no need to worry the VLAN the packet and data.  But I use that I have several farms esxi in a different subnets from the management and the 1000v in a subnet for network management.

  I hope this helps.

• several subnets by VLANS and ports link

  Hello

  I need some clarification.

  Our iSCSI SAN storage (Dell MD3660i0 requires a separate subnet by port.

  We require paths multiple access and balancing in VMware.

  To achieve this in ESXi 5.1 we need binding ports... BUT the binding of ports is supported only if the vmks are all in the SAME domain in accordance with these two KBs broadcasting

  VMware KB: Considerations for use binding software iSCSI ports in ESX/ESXi

  VMware KB: When the use of several VMkernel ports with port required to access the storage of two or more tables on different br...

  OK... probably so I simply put my all subnets in ISCSI storage in one VLAN and everything will be ok (one VLAN is after all a broadcast domain, both are stuff of L2)... This would respond to the requirements of KBs... If VMware means "area of distribution" in the true sense of the term.

  So my question is can you configure the port in this way binding? It is supported by VMware?

  VMware has come back to me (in fact the author of one of the kb/s I've referenced)

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=2038869

  He confirmed that the terminology used in the KB is misleading and "broadcast domain", it actually means "subnet" so not layer 3 layer 2.

  This means that you can NOT have multiple subnets in a broadcast domain (VLAN) AND use the SW iSCSI port binding.

  BUT

  He told me (he is very familiar with the Dell MD3660i iSCSI kit), you don't have to have binding of ports to achieve several Multipathing and load balancing. If you have a requirement for several subnets of your iSCSI SAN provider then just create multiple vmks on different subnets, and DO NOT make the port binding. The fact that they are on different subnets will be enough to achieve the multiple paths

  It updates the KB to make this much clearer.

  I hope this helps someone

• 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.

• 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.
