• Hosts distributed Virtual Switch cannot ping each other

  host of vSphere 4.0, introduced 2 vSphpere B and C hosts and all put in a switch of distruduted to VMkernal network. Only the host can vmkping has a virtual machine that was put into the same switch and the VM also ping on host A. But, 3 hosts cannot vmkping between them, and B and C cannot vmkpng the virtual machine.

  What is the problem and how can I solve this problem?

• DLR Uplink and GSS internal transit same VXLAN cannot ping each other.

  Start with, I run NSX 6.2.2 firewall rules on 'allow all' to 'all' to 'all' "all protocols", in other words disabled...

  I have a VXLAN 5000 transit, with an uplink DLR interface attached to it, and an internal interface GSS in the appendix in which neither of the parties can ping to another. So for troubleshooting, I added 2 VM Windows attached to the same transit VXLAN 5000, a virtual machine is on ESXi host 1 and the other is on host ESXi 4. They can fine ping each other, and two virtual machines can ping both the uplink of DLR and internal interfaces of the GSS.

  This question has puzzled me because it makes no sense, why the DLR and the GSS cannot ping each other but 2 virtual machines that VXLAN can ping all adjacent devices. I can even put bridges on those virtual machines with a rule NAT on the GSS and those virtual machines can get internet through the GSS, but no matter what I try, the DLR cannot ping the GSS, and the GSS cannot ping DLR...

  I need to define a static route between the GSS DLR <>- but if I can't even answer ping interfaces I'm dead in the water.

  If I install virtual machines in a network LAN DLR interface such as WebApp and test for example database, I can ping throughout the DLR together until the IP DLR Uplink, but then he cannot ping the GSS internal.

  Does anyone have suggestions for troubleshooting? Test commands that I can run? I tried many things and then lots of websites with the troubleshooting steps. Everything seems fine, all green checks in the installation steps... All roads, MACs, ARP tables appear as expected when I run test on host computers commands and controllers. I don't know what is the cause except for a bug in the code...

  All ideas are welcome... Thank you

  UPDATE:

  Yes, so it has need of a static NAT rule on the GSS...

  In my environment, I added a SNAT rule on adapter: ESG_Uplink with 0.0.0.0/24 CBC-translation dst: 1.1.1.101 (my lab ESG IP Uplink).

  It works now... VM tenant box connected to WebApp portgroup (192.168.13.115) can now ping gateway DLR, through routing OSPF to the GSS and ping on physical bridge of...

  I learned a lot on this one... I'm not going to worry about why the static route, I tried first post didn't work, since I was the OSPF running instead (which is more appropriate for my laboratory for realistic scenario anyway), and the Foundation will now suffice to build the rest of this POC vRA / vRO lab...

  Thank you in any case, sometimes it's just nice to have someone to listen.

• 2 vSpheres cannot ping each other that are built on vSphere.

  On host A, which is vSpere 4.0, made up of two hosts who are vSpheres 4.0 with vSwitch. Each can ping itself, but cannot ping each other, too, cannot ping A host. After that the two hosts are moved to dvSwich, has achieved some results. But another VM on the dvSwitch is fine.

  Moreover, I need to practice the vHA and vmotion. So, I need two some configuration for her guests. As a result, I built two hosts on A host.

  How can I solve this problem?

  Thank you!

  George,

  You must set the Promiscuous Mode to Accept on vSwitch guests (--> security properties).

• Cluster nodes cannot ping each other

  Hello

  I recently put one of our old clusters online it's a server poweredge 1855. I work at 5 knots, and there a PowerConnect 5316 M switch on the back. 5316M has only 1 cable connecting the switch to uplink.

  Each blade has 2 NIC one of them is a NIC, with a normal IP on our range of normal production. All blades can ping this address each other, and they all have internet.

  The other NETWORK adapter is what I use for live migration, or pulsation of cluster or something... Whatever it is, it has a different range with no gateway (172.50.1.x)

  Now 3 of the blades can all ping eachother, but not the other 2. And 2 that can not ping, can ping each other. It seems that the 2 are on the same VLAN, and the other 3 are on the same VLAN.

  The problem I have, is the switch shows them all on the VLAN by default... and one thing that I can't work... If the servers all have 2 network cards, but there are only 10 ports on the internal switch?... so, how can I set or the other card NETWORK on one VLAN different?

  The configuration of the switch is here:

  This document does a good job of showing how interconnections.

  www.Dell.com/.../ps3q05-20050163-Brundridge-OE.pdf

  Module e/s 1 goes to port 1 and i/o 2 module goes to port 2 of the LOM standard.

  It is therefore useful to check what ports are used by the server. If the 3 are on port 1 and then the other 2 are on port 2, try to get all the 172.50.1.x addresses assigned to port 2 for example.

• Cisco ezvpn ASAs cannot ping each other inside interfaces

  I have a set ezvpn in place with a 5506 (position B) client-side and a 5520 (location A) server-side. I have successfully connected vpn, and traffic flows. My problem is that I can't SSH in the location b. investigate this more than I can not ping is within the interface of the ASA opposing, or the machines inside each ASA ASA.

  I found the following links that describes a scenario similar to mine, but nothing on one of them helped me.

  Hi Adam

  The site of B I'm not able to see "management of access to inside. Please try to set up the same. He could solve the problem.

  Also on the instruction of the ASA takes place nat can you please try to add keywords 'search non-proxy-arp route'.

  something like:

  nat (inside,outside) source static (Location A)_Networks (Location A)_Networks destination static (location B)-remote_network (location B)-remote_network no-proxy-arp route-lookup

  as I have noted problems with inside access to interface via the VPN when those keywords are not applied. If I remember correctly 8.6.x ASA version had a bug regarding the same. Cordially Véronique

• Two VMS on different networks and ping each other

  Hello

  I'm using VMware Workstation for the first time. I have two VM and I want them to be on two different networks. I want that networks be able to ping each other. I did research on this since yesterday and nothing seems to work. Perhaps I am confused with the bridge, the Nat and host-only adapters. What I have is:

  VM1-> has two network adapters: VMNET1-Host-Only (192.168.247.128) and VMNET8-NAT (192.168.42.130)

  I'm not able to have the internet connection on the HOST only

  VM2-> has a network card: VMNET8-NAT (192.168.42.129)

  Each virtual machine I can ping everything on the other virtual machine, but it seems a little odd.

  Is there another way to do this?

  Thank you very much

  Although you can create several networks in VMware Workstation, there is no possibility of embedding to do the routing.

• Need router and switches for simple network tips...

  I have to get a new router and switch to an office with 9 computers, 1 printer, and a server.  They are all Mac computers. Two Mac computers are running Windows XP through Parrallels (not sure if it matters).  All computers have just need access to the Internet (through the router), access to the printer and 5 of them on the server.  A few more important details: the router will be located about a quarter of a mile away (where we could get a broadband Internet access) but will have a fiber optic cable running to the office, where will be the selector. In the building off site where the router, we would like to have a backup disk to send important files at the end of each day (or set up to do this automatically later).  The optical fiber has capacity of the card.  We want that the router must be connected only (wireless).  Any suggestion that router and switch combo would be enough?  Thank you!

  You can use a RVS4400 router that has a gigabit capacity with 4 ports, connected to the gigabit switch.

• PC Windows 7 and Vista Home Premium computer network cannot access each other

  I have an a Premimum Vista computer with a USB printer on a network with a Windows 7 Ultimate Computer.  Both recognize each other both are visible in the network on both computers) but I can not access one or the other.  Message on window 7 says "your computer seems to be correctly configured but the resource does not."
  "Any suggestions?  I need to produce and share printers.

  Here are the steps of general network troubleshooting. Just cannot apply to your situation, so just take the bits that are. It may seem daunting, but if you follow the steps in the links and suggestions below calmly and consistently, you will have no difficulty to implement your sharing.

  Problems sharing files between computers on a network are usually caused by 1) a misconfigured firewall or a firewall neglected (including a dynamic firewall in a virtual private network); or (2) inadvertently run two firewalls such as the firewall of Windows and a third-party firewall. and/or (3) do not have accounts to the same users and passwords on all computers in the workgroup. (4) tries to create actions where the operating system does not.

  Excellent, comprehensive, but easy to understand article on sharing files/printer under Vista. Contains information about sharing printers and files, and the folders:

  http://TechNet.Microsoft.com/en-us/library/bb727037.aspx

  In Vista, turn on password protected sharing. In Windows 7, go to control panel > everything in Control Panel > network and sharing Center. Click on "change the advanced sharing settings. You don't want to use the residential group unless you have all Windows 7 machines. If you do and you want to use the homegroup, see Windows 7 Help & Support. Otherwise, in sharing advanced:

  Discovery of plug in the network
  Open the files and printers sharing
  Turn on the sharing section Public folder sharing
  Plug the password protected sharing

  A. configure the firewall on all machines to allow traffic to local area network (LAN) as being approved. With the Windows Firewall, turning on window file sharing and printer as the above will take care of that for you. If you are not running a third-party firewall or you have an antivirus/security with its own firewall component program, then you're fine.  With a third-party firewall, I usually set up the allocation of LAN with an IP address range. E.g. would be 192.168.1.0 - 192.168.1.254. Obviously you would substitute your correct subnet. Refer to the safety of any third party program or the user forums for how to correctly configure its firewall. Do not run more than one firewall. DON'T STOP FIREWALLS; CONFIGURE THEM CORRECTLY.

  (B) to facilitate the Organization, put all computers in the same workgroup. This is done from the System applet in Control Panel, the computer name tab.

  C. create the counterpart of the user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and assigned to each user account passwords can be different; accounts/passwords just need to exist and to match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY OF SIMPLE. If you want a machine to boot directly to the desktop (a particular user account) for convenience, you can do this:

  Start > Search box > type: netplwiz [Enter]
  Click continue (or provide an administrator password) when you are prompted by UAC

  Uncheck "users must enter a user name and password to use this computer". Select a user account to connect automatically by clicking on the account you want to highlight and press OK. Enter the password for this user account (when it exists) when you are prompted. Leave blank if there is no password (null).

  D. create shares as desired. In Windows 7/Vista I usually shares its office and the Public directory.

  E. After you have the job of file sharing (and tested by exchanging a file between machines), if you want to share a printer connected locally to one of your computers, share of this machine. Then go to the printer mftr Web site. and download the latest drivers for the correct system. Install them on the target machines. The printer must be collected during the installation procedure. If this isn't the case, install the drivers and then use the Add Printer Wizard. In some cases, printers must be installed as local printers, but that is beyond the scope of this answer.

• How is the best way to connect the configuration of my router and switch?

  I have a cable modem. connect to a switch, I have 2 computers connected to the switch. I also just connected my router wireless switch. That's the best configuration or I lose my firewall of the router in passing is not by ports directly above?

  Most of the cable modems will give an IP address, so connect a switch to the modem and then connection of two computers and a router to the switch will usually result in one of these three devices, get an IP address (and internet connection), while the other two will not be.  (Notice that I guess a true "Modem" and not a "Modem/Router" device).  The correct configuration would be to connect your router to the modem (router gets the unique IP address).  The router can then process from the addresses IP what either side LAN of the router, then plug the devices you need (including switch) to the router's LAN ports.  This also ensures that all devices will be on the same subnet that your connection scheme to separate devices on the router wireless from the other two devices on the switch (here, assuming that you have a router/Modem device).

• ACL router and Switch

  Hello.

  I have a small question.

  I implemented a simple extended ACL.

  ip licensing 10.10.10.0 0.0.0.255 192.168.1.0 0.0.0.255

  refuse an entire ip

  It is enabled on the SVI interface IN direction with ip 10.10.10.1/24.

  When I test with the ping from the router to a network blocked from using the interface (SVI) source ACL does not work.

  Example: ping source 172.16.1.5 10.10.10.1 = success.

  This should not be blocked and only allow traffic to 192.168.1.0/24?

  So my questions. The ACL effect on the interface of the router itself and only other hosts on the subnet / vlan? (I think I remember having read about it, but can't find it)

  Thank you.

  Hi traffic there, navigate the interface so that the ACL to be considered. Here is a link to another thread on the forum that explains this very well:
