• Cannot connect computer second to 8600Plus via the wired network

  I am trying to connect a computer to second and third on a 8600 more all-in-one that has a wired connection to my router.  The main computer is also connected to the router and works fine with the printer functions.  My second and third computers have wireless to the router connections.

  I installed the software, but no computer recognizes the 8600 over the network - the error message is "printer not found."

  I tried to reboot the router, the printer and computers, all nothing will do.

  I can connect to the Web server on the printer to all computers, so there is no doubt about the connection or the network.

  Enter the URL of the printer (192.168.2.100) during the installation process also produces the error "printer not found."

  All welcome suggestions for what to try next.

  Thanks a lot for your suggestion and the quick response.

  It was not so, but I have now found the solution.  I remembered that I had a lot of trouble when I first implemented more than 8600 a few months ago because it's not co-exist well with my Netgear ReadyNAS Duo, who is also on the network.  With its default settings, more than 8600 causes the ReadyNas disconnect.  I finally solved this by disabling Hello, SLP and WS Discovery in the network settings of the 8600 more.

  But it seems at least one of them is necessary for the installation of 8600 program to detect the printer, but once installed, they are not necessary. So the final solution is:

  1. turn off the SIN ready

  2. turn on Hello, SLP and WS discovered on more than 8600

  3 complete the installation of the more 8600

  4. clear Hello, etc.

  5 reboot the ReadyNAS

  Simple!

• Cannot Connect to Host ESXi 4.1 with browser or Client VI

  Hi, I have a strange problem which has persisted since I first installed ESXi 4.1 on a server. First my setup:

  • ESXi Installable on a HP DL380 G6 server, 32 GB of RAM, 4xEmbedded NETWORK ports, Port NIC, 2 iSCSI x QLogic QLE4060C HBAs 1xDual adapter

  • HBAs configured for Jumbo and static IP frames but except that all the settings are default

  We have installed ESXi 4.1 with only the built-in port #1 connected to the switch. Everything went well and we were allocated the only active NIC (vmnic0) as the management interface. Once installation is complete, we were able to connect to the management interface using a browser and the VI client.

  We then connected NETWORK card and remaining HBA ports to the switch without loss of connectivity to the management interface. During our next restart we could no longer connect directly to the host using a browser or the VI client but could still ping the IP.

  We tried to restart the management agents, but it did not help.

  Here are the different startup scenarios, we tested and the results:

  Scenario #1 - Boot with built-in NICs, DP adapter cards, network and HBAs connected to the switch.

  • Can we ping the IP of host of Mgmt? = Yes

  Can • we consult to the IP host of Mgmt or connect using the VI Client? = NO

  Even if we try to unplug the adapter DP and HBA ports after starting we still cannot connect to the management using the Explorer or the VI Client interface. A reboot is required, and the script #2 or #3 must be followed.

  Scenario #2 - start with only the embedded and DP adapter NIC connected to the switch.

  • Can we ping the IP of host of Mgmt? = Yes

  Can • we consult to the IP host of Mgmt or connect using the VI Client? = NO

  If disconnect us the two ports of adapter DP we can then connect to the host via the browser or the VI client without having to restart. We can reconnect them and we continue to have access to the host, and everything is fine.

  Scenario n ° 3 -Boot with only the NIC integrated, including the Mgmt NIC connected to the switch.

  • Can we ping the IP of host of Mgmt? = Yes

  Can • we consult to the IP host of Mgmt or connect using the VI Client? = Yes

  Then we connected the DP adapter and the adapter port HBAS to the switch and all the connectivity was very good. This scenario is our solution for now.

  Other information

  The QLE6xxx ESXi module takes about 5 minutes to load during startup, when the HBAs are connected to the switch, but it loads successfully. Not sure if this is normal or not.

  Thank you in advance for your help!

  This looks like a very unusual network for me configuration.

  Could you post a screenshot of virtual network configuration and add a few comments on the different configuration of the vSwitches and uplink connected.

  If I understand correctly that you have at least 3 vSwitches (management, virtual machines, and iSCSI), however, from what you wrote so far I do not completely understand how implement you.

• New Unifi AP-AC-LR and AP-AC-Pro does not not with Sonicwall Soho

  We have been installing Unifi AP running off a Dell Sonicwall port to several facilities for more than 6 years with no problems. We are now to modernize both the Sonicwalls for purposes of strengthening security and Unifi to add increased range and 5 GHz units.

  The Sonicwall is Sohos Dell.

  Unifi units are AP-AC-LR and AC-AP-Pro (we also tested older Unifi units which are only 2.4 ghz with the same results). Running off the 4 port X.

  Old Unifi AP works OK with the old Sonicwalls.
  The new Unifi AP works OK with the old Sonicwalls.
  Old Unifi AP works OK with the new Sonicwalls sometimes.
  DO NOT work with the new Sonicwalls Unifi AP new.

  Our wifi monitor shows an initial connection and wifi, which takes maybe a minute or two, then the wifi goes off the air. Reset of the Unifi POE gives place to the Unifi appearing on the air again for about for about a minute or two.

  Both the Sonicwalls and of AP Unifi are running the latest firmware.

  Suggestions on what to look at would be appreciated.

  Thank you

  We have received information that it has feature in the Unifi AP that can be triggered by the the Sonicwall causing the AP of Unifi shut down. It is the uplink connectivity monitor. We will test turn it off and see what happens.

• UCS 2.0 Documentation loop

  Hey all,.

  I am interested in the THICK scaling with interconnection mode the port channel.

  The next section in the Configuration Guide indicates that there is a document:

  http://www.Cisco.com/en/us/partner/docs/unified_computing/UCS/SW/GUI/config/Guide/2.0/b_UCSM_GUI_Configuration_Guide_2_0_chapter_01110.html#concept_09169B12A90C4581B16592B8B8963491

  Where there is a link called:

  KEEN, scaling for the Mode Port channel fabrics

  Which loops to the same page.

  Google search for the title I make no where except the following:

  http://www.Cisco.com/en/us/docs/unified_computing/UCS/HW/chassis/install/install.html#wp1346269

  Once again, no real detail except:

  Inside the 6248 fabric interconnect, there are six sets of eight contiguous ports, with each set of ports managed by a single chip. When the uplinks are connected such as all uplinks from the IOM are connected to a set of ports managed by a single chip, Cisco UCS Manager optimizes the number of bait used in the profiles of service deployed on the blades in the chassis. If the IOM uplink connections are distributed through the ports managed by separate chips, the QUICK count is decreased.

  Can someone point me to the actual documentation scaling of high HEAT?

• Modules SFP to use on catalyst 3650-24TD-E

  Hello

  We intend to buy a catalyst 3650-24TD-E switches, and I would be about to buy the good modules SFP and SFP + for it. As you know, this switch model supports 2 1 Gigabit SFP and 2-port 10 Gigabit SFP + uplink.

  We have already other catalyst 2960 switch with SFP GLC-SX-MM modules for uplink connections.

  What SFP / SFP + models you recommend?

• A matter of design of LAN switch

  Let's say in a configuration there are two standalone Cisco 6509 switch core (core 1 and core 2), connected each other with between etherchannel link. Interface VLAN (vlan 10,20,30,40) was created in the two switches to base with the HSRP configured in VLAN to provide gateway redundancy, currently interface gateway active all the VLANs are 1-based, and core 2 acts as a sleep state.

  There are also 6 network switches, each access switch with an uplink connected to the basic 1 and 2 respectively to provide basic redundancy. All switches access have all positions of vlan 10,20,30 and 40 associated and configured with them.

  Then, of course, that Cisco 6509 is the place of the idea to become the bridge root STP in the installer, I think that

  (1) core manually configured 1 as the brigdes root for all the VLANs

  core1 (config) # spanning - vlan 10-40 the square root of the drive shaft

  Core2 (config) # spanning - vlan 10-40 the square root of the secondary shaft

  or

  (2) manually configured and separate the brigdes root in core 1 & 2 core

  core1 (config) # spanning - vlan 10-20 root of the drive shaft

  core1 (config) # spanning - vlan 30-40 the square root of the secondary shaft

  Core2 (config) # spanning - vlan 30-40 the square root of the drive shaft

  Core2 (config) # spanning - vlan 10-20 root of the secondary shaft

  So who is the best choice and best practices in this case to get the best performance, or there is no significant different between them

  BTW, the Cisco 6509 core is and access switches are all performed on spanning tree pvst mode. Thanks in advance

  Best regards

  Wai

  To be honest, we had the same exact configuration with 60 switches to user access (each port a 48 and 98% of the capacity) and 63 VLANS and 6509 switch CPU was 1-2% with a SUP720. At peak hours I sometimes saw him go to 5%!

  We started to L2 and L3 load balancing but through the network with servers linux and gluing problem (dman server guys) came back to us to option 1. Never had a problem since.

  Then you should be OK.

• Windows Installer stucks at "preparing to remove...." "whenever trying to uninstall the program

  Hello.

  I need help to solve this problem. A few days ago I was installing and uninstalling many programs... and Windows Installer did not show any kind of mistakes either. Now when I try to uninstall a program, it just stucks at 'Preparation delete... '. "and when I click on 'Cancel', nothing happens, so I need to complete the process in the Task Manager.

  Windows Installer may be damaged or something, I don't know why it won't uninstall programs more. I tried to uninstall programs, when I click on one of the programs, only a stucks too and I need to cancel the uninstall Microsoft FixIt tool.

  I have download some sort of "Revo Uninstaller" it stucks on this one aswell, as no doubt everything is connected to the Windows Installer service.

  I tried to restart the service, and then restart the computer, always it stucks. Interesting thing is that he wants to install programs actually but won't uninstall them. Only way to uninstall is to go to their folder and click on one of the executables that suggests to "Uninstall" program. Problem is, that some of these programs have not just in their file and who is right for which I need to uninstall from the control panel.

  I'm trying to understand this for two days already, not to do. The only change I made to the system, it's that I have installed the latest graphic driver NVIDIA GeForce customer experience through. Nothing else.

  I don't want to reinstall Windows because of this. It's pain the *, and I did not restore point system, so I'll lose everything if I re-install the entire system.

  P.S. I'm sorry if I chose the wrong category. I've no idea what Windows should be the problem of mine.

  Hello

  Revo is a great little program and works independently of Windows.

  Malware related programs have a tendency to not let you uninstall them, no matter what you do.

• Grouping of NETWORK cards

  Hello

  I am new to virtualization and have a basic question about the collection of NETWORK adapters. I have a host with a NETWORK card with 2 ports (vmnic0 and vmnic1). I have a network cable connected to vmnic0 and vmnic1 is open without any network connection to the outside world. Can I use grouping of NETWORK cards in this case? Or both network adapters must be connected to the network for NIC teaming to work?

  You can certainly configure everything as if the two vmnic was active. However, with a single uplink connected to a physical switch, it may not make much sense.

• Essentials Plus temporary installation

  I currently have two servers Dell PowerEdge T110 with hypervisor ESXi6 configuration.  Each server has 16 GB of RAM and the local drives of 1 TB.  My plan is to replace these servers with R630 servers with 24 GB of RAM, but that occur for 3 months another funding arrives.  I have already received our Essentials Plus package and want to create on the existing servers so that we can 'play' with it and get used to the system.

  I know the recommended minimum requirements, but think I might stretch what is a little until the upgrade servers arrive for my purpose.  So, my thought is this:

  update my hypervisor from ESXi6 to ESXi6 with the Essentials Plus licensing servers

  Installing vCenter with features incorporated in the form of an appliance

  I only have 2 network adapters on each server.  Then, I plan on the uplink connection as follows:

  1 uplink - management and Vmotion

  1 uplink - VM

  I'll keep the local disks for storage BUT when arrive upgrade servers I plan on converting these T110 servers NAS servers.  The R640s will be delivered with 4 network cards so I should be in good shape

  I think it will work temporarily for purposes can I training?  Any advice?

  Nothing inherently wrong with that. I think you'd be better of just standing back a new server vcenter for your new hosts and placing them in together and then dismantle this environment later. But even once, there is nothing wrong with what you want to do and then set up the policy of clustering and failover for ports VMK 1 active and 1 sleep just so you have a redundancy in all areas other than the fact that I place two network cards on a single vSwitch. If you use only local storage, however, vMotion is irrelevant. You will lose your mind in waiting for the virtual machines to move through a unique NETWORK adapter without shared storage.

• NSX - Ping issues between DLR and edge gateway on the network of public transport

  Hello

  I have deployed an NSX in a POC environment and have a few weird questions. I sent a distributed router (DLR) with 2 internal interfaces (related to the segments of NW app & web) and an uplink interface connected to a network of transit (192.168.10.0/29). I have also deployed a gateway of Edge services with an internal link connected to the same interface of transit (192.168.10.0/29) and an interface of uplink connected to the outside world.

  The question is, when I PuTTY on the Edge service gateway and ping interface uplink of the DLR using sound transit (192.168.10.2) network ip address, I do not get a response. The firewall is configured to accept all traffic on the DLR and the edge.

  Someone at - it ideas? Note that the DLR has been configured default gateway pointing to the IP of the gateway of the Edge on the network of public transport (as is the only North DLR connection)

  See you soon

  A rough drawing of the topology is attached. Ping fails to 192.168.10.1 to 192.168.10.2

  FYI - has proved to be a problem with the NSX 6.1.2 that attaches to 6.1.3. No KB for the issue for the time being, nor is he mentioned as being fixed at 6.1.3 in the notes but VMware engineer GSS confirmed that its fixed.

  temporary work is about to stop and start the daemon netcpa on the compute cluster hosts & edge of ESXi

• VMware vCenter living is no longer working with Acronis Backup Advanced, Help!

  Hello everyone, I hope this ad in the right area of im, I'm looking for some advice on what could be causing my question about integration using the byproducts, I am struggling to find something on the net that relates exactly to my problem so have resorted to forums to see if anyone has tips or ideas , like im fresh out of them now!

  • VMware Client & Server Version 5.5.0 - (VMware vCentre Server Build 1476327)
  • Acronis advanced backup (Version 11.5 - update 5)

  Since November the synchronization / VMware vCenter integration between the 2 products above seems to have stopped working correctly, which means that any change in the location of the VM machines in the VMware customer environment is not reflected in Acronis more.

  For example, when you move a virtual machine to a folder on a particular data center to another folder in the same Datacenter, this change should be so reflected in the Acronis, what is happening is no longer.

  In addition, when a virtual machine brand new is created in vSphere and is placed in the appropriate Center of data/file structure, this should (and working correctly until November) fill with Acronis 'vcentre' host Group that has the folder structure equivalent to pick up the plans for appropriate backup etc, but this happens is no longer, instead , the only way that you can see the new VM is under "all Virtual Machines.

  In addition, when removal of vSphere VM, also not being properly reflects Acronis more, when go in "All Virtual machines" these deleted machines are still show while intoxicated. But these machines no longer exist in vSphere, this shouldn't show Acronis more. Without doubt, this is connected to vCenter integration issues.

  Here are the steps I took to try to solve this problem

  • Disable/re-enabling integration with the server vCentre.
  • Restarting the Server Service on the management of Acronis Acronis license server
  • Reset all motors of unloading and the virtual machine.
  • Acronis and vCentre servers restarting.
  • A reconstruction complete the Acronis server and all subsequent config, etc. backup plans.

  After the last point (reconstruction of Acronis) integration has worked for a few days, then it stopped working again!

  If anyone has any ideas or possible causes, could you please let me know.

  Here are a few details of what was the root cause of the problem:

  Each VM in vSphere contains a list of parameters such as:

  InstanceUUID

  locationID

  guestFullName

  The problem arises because some of the virtual computers contains a copy of the values of these parameters (name, value). Thus, in order to update the database of AMS, we execute the SQL query with these settings, but when 2 or more of the virtual computers contains the same parameters, the SQL query fails > This is why the changes were not reflected and it was not possible to update the vCenter folder structure.

  The developer removed then duplicate values enable and disable the vCenter integration, by doing this it was able to resolve the problem.

• VMware device with 2 network cards claiming the same IP address with two MAC addresses

  Hello.

  I see messages intermittent my gateway network two MAC addresses associated with a virtual machine running on a 5.5 ESXi host for the same IP address.

  The virtual machine is a MiTel 3300 controller for a VOIP system. the system is configured with two IP addresses, one on the local network and another with a public IP address in the DMZ. In the network configuration of the 3300, I assigned the address LAN IP at 00: 0C: 29:30:B2:B2 and the DMZ IP at 00: 0C: 29:30:B2:BC (Mac for network devices presented by the ESXi host virtual machine).

  On the host, I configured a vSwitch with exclusive access to two physical network adapters on the host machine. The vSwitch is configured with two machine virtual port groups, LAN and DMZ, with access to the physical network interface cards. Tab grouping of groups vSwitch port NIC, I replaced the order of failover of the switch to activate an active NETWORK card only for the Group of LAN ports and the other card NETWORK only for the DMZ port group. (I don't know how the content of the column of networks is determined. Neither is correct for the traffic on the physical switch. If these are configurable, please advise and I'll change the settings). The relevant parameters of vSwitch, groups of ports and VM are distinguished below.

  On the virtual machine itself, through the VMWare host, I assigned 00: 0C: 29:30:B2:B2 for the Group of LAN ports and 00: 0C: 29:30:B2:BC to the DMZ group port (best I can tell, anyway, since the MAC address field annoyingly obscures the last two digits of the MAC address - break if I invert the mapping) (, but all seems OK).

  The goal here is to make sure that MACs of ports vSwitch the 3300 is listening and sending always correspond to the physical ports that are VLAN Tag by the physical switch to ensure the routing. Generally speaking, it seems that what is happening but, intermittently, we cross one-way calls that suggests a problem of routing between us and our SIP trunk provider; coinciding with these incidents, I get an email along the lines of "the security in the network device has detected a conflict of IP address with two or more devices. The period of INVESTIGATION "DMZ. DMZ. DMZ. DMZ' is claimed by the following clients with MAC addresses: ' 00: 0C: 29:30:B2:B2' ' 00: 0C: 29:30:B2:BC'. »

  I did something in the configuration that would lead to this kind of collision intermittent? Have a hacked together a way to do something that could be accomplished in a way that is simpler and more reliable?

  Thanks for any idea that you can offer.

  Kind regards

  J.

  

  

  

  I probably don't fully understand your configuration, but it seems that you are not interested in using the collection of NETWORK adapters in the virtual switch of the VM MiTel 3300.

  If it is correct, why not create two virtual switches, each with a group of port (LAN and DMZ) unique and with a separate connection of (vmnic2 and vmnic1)?

  In general, collection of NETWORK adapters may be used to share traffic between uplinks and ensure that if one of the uplinks connect fails, a virtual machine still has access to the network.

  This post should help determine the number of hosts.

  VSAN part 25 - hosts much-needed to tolerate failures? CormacHogan.com

  The number of disks is harder once you start adding bandwidth, because you also have to take into components witness account.

  Each band will require a disc, and you increase FTT, you will need to double the number of disks you want to mirror any of the components score. And then, of course, welcome the witnesses.
