Server with 3 NICs wants to connect to 2 switches

I have two 6509 on the distro layer ( distro 1 and distro2 ), running layer 2 only. They are connected to two 6509s on the core layer. One of the server admins has a 3 port NIC on his server bundled together to increase bandwidth. He wants to connect it to 2 ports on the distro1 and 1 port on the other distro2 switch. All 3 distro ports he is connecting to are in the same VLAN and the VLAN is allowed on all port channel connections between distro and core switches.
Will this even work since he is connected on different switches?

Those stating that a NIC channel is not allowed to two individual switches should know that a NIC teaming is usually not a link aggregation (port-channel). If it is an active-standby-standby NIC team then all you need is to make sure all 3 ports belong to the same VLAN. Traffic will leave the server on the active link and the switches will learn that the MAC address is on this port. No Port-channel config is necessary on the switches.
Load-balanced NIC teaming usually requires Port-channel if the same src MAC address can appear on multiple ports. In this case multichassis link aggregation is mandatory and you cannot connect to individual switches.

  • Security Manager on server with teamed NICs ?

    Can anyone confirm that Security Manager will run on server with teamed NICs (i.e. 2 physical connections, but 1 logical IP address) ?
    I ask because the data sheet for Security Manager 3.0.1 states :-
    "100BASE-T (100 Mbps) or faster network connection; single interface only". and
    "One static IP address".
    I already have a server that meets all the specs, but it has dual NICs to dual switches for resilience, teamed together with a single IP. The Cisco document is open for interpretation, so has anyone got a definitive answer or is running a setup like this already ?
    Thanks.
    Mark.

    It's recommended that you can use only one interface when installing CSM. However, if the second interface is using the same IP it should not be a problem.

  • WOL question. SCCM server with multiple nics.

    Hi,
    I have a sccm server with multiple nics, I can wake up any machine using a 3ed party magic packet utility, if I set a schedule and use sccm wol functionally the machine never wakes up. As I pointed out my server has multiple nics, does anyone have a sccm
    server with multiple nics with sccm built in wol functionally working?. I am curious on how you achieved this.

    Hey Garth,
    Yes the problem is solved but we had to buy a 3rd party power management utility to accomplish WOL. Because we have many different subnets in our environment we found that this was the fastest way to get WOL working,
    So out of the box SCCM would not work for us, with a 3rd party utility that had an SCCM plugin WOL now works flawlessly.

  • Windows server with one NIC and two IP address answers to ping with wrong address.

    Hi,
    I have Windows 2012R2 server, as a web server. It has only one NIC, and I have given it two IP addresses. 10.0.0.11 at the main Window, and under the advanced tab, I have added 10.0.0.12 as additional ip to the nic.  I have even but to
    host file a row, that states 10.0.0.11 server.domain.local.
    Now when I ping "server.domain.local" from the server itself, it gives me 10.0.0.12 as answer.
    With nslookup I can get correct address (10.0.0.11). But when I type server.domain.local to the web browser it tries to connect 10.0.0.12, which is incorrect. It should connect to 10.0.0.11 address. Could you please help me?
    Regards,
    Jouko

    Windows does not work well with two IP addresses on the same subnet.  Results are inconsistent, as you have discovered.  In general, you should never try to put two IP addresses from the same subnet onto a single Windows box.  That means either
    multiple addresses on a single NIC or on multiple NICs.
    Maybe if you tell us what you are trying to accomplish by having two addresses, we could provide better assistance.

  • I have 10.5.8 macbook with a firewire and want to connect to my Sony Camcorder 2005 iLINK.  What adapters do I need?

    I have 10.5.8 macbook with firewire and want to connect to my sony camcorder 2005 iLink.  I believe they are both 4 pin and need male connecters.  Can anyone help me?

    Go to the Apple in the upper left corner and select About This Mac, then click on More Info, then select Firewire from the left hand column of the System Profiler.  If it says "Maximum Speed: Up to 400 Mb/sec" then this is the cable you need http://www.amazon.com/Cmple-IEEE-1394-FireWire-iLink-Cable/dp/B00403TH0C/ref=sr_ 1_8?s=electronics&ie=UTF8&qid=1311376173&sr=1-8

  • How do I access server with VPN?

    I have a connection via VPN to my work from home now. I'm on a MBP 10.6 and work is Cisco IPSec. It show the connection in my menu bar.
    My question is how do I now see my work files? I figured the vpn connection would show in my sidebar or on my desktop. This is the first time I have tried connecting to work from home.

    VPN normally just gets you into the network. You then have to mount the server's shared volume to see files. Depending on how the network is set up, you may be able to browse for the server by clicking on "All" under the Shared header in the Finder Sidebar (you may have to click the disclosure triangle to see things under the "Shared" header). It will be easiest if you then select to show the window in Column view. If you see the server to which you want to connect, click on it and you should be asked for a user name and password; if not, click the "Connect As" button that should appear in the next column.
    If you can't browse for the server, use the Connect To Server command under the Go menu in Finder and enter in the appropriate URL to the server; check with your server administrator for the correct information.
    Hope this helps.

  • Very slow network performance with Intel NIC when TCP Large Send Offload is enabled

    I have a Windows 2008 server with two NIC's (Intel PRO/1000 PL and Intel PRO/1000 PM), and one virtual external switch connected to each NIC.
    With the 01/14/08 network driver, I get very low throughput on both NIC's (~10KB/sec when downloading from my server when it should be around 11MB/sec).
    I've found that disabling "TCP Large Send Offload (IPv4)" on the virtual switch and "Large Send Offload v2 (IPv4)" on the physical adapters solves the problem.
    Is this a bug in the driver?
    Thank you,
    Ricardo Costa

    2 years later, I was able to get that machine to work with Hyper-V under Windows Server 2008 R2, but only after disabling everything that had anything to do with TCP or IP offloading.  I think that I had to turn off 4 settings on one controller,
    and 5 settings on the other controller.  Once that was done, everything worked flawlessly.  It is very apparent that the Virtual Controllers do not properly use many of the features of non-Intel devices (not all Intel devices work either), and
    that Hyper-V does not completely uninstall if you remove it.
    If you have any problems, start turning off the features that your adapter supports, until it starts working.  You'll need to weight the cost of replacing the controller with a fully supported controller, of which there is no list, or using your existing
    controller at a capacity lower than it physically supports.  This has been an elusive issue with Microsoft's Virtual Server projects since they were first in beta, so don't expect a fix anytime soon.
    P.S. For those who don't know, the settings are on the actual device and can be changed in the Device Manager.  If you are still having trouble after turning off all the settings, then you will need to replace the controller(s) with a different
    make/model.

  • How to route traffic across subnets when one NIC is a hyper-V virtual switch?

    Having a bit of a problem with a hyper-V environment which does not seem to route network traffic on two different subnets between each other.
    If it were a purely physical server with two NICs and a gateway set traffic would automatically be forwarded between the two different subnets.
    However when one of those NICs is a hyper-V virtual switch this simple routing no-longer seems to work and no traffic gets forwarded between subnets?
    Situation is:
    Hyper-V server with two NICs
    NIC 1 = 192.168.0/24 - main Internal company network.
    NIC 2 (hyper-V virtual switch.) = 192.168.1/24 - connects to ADSL internet router
    Virtualized Domain Controller.
    One or two virtualiszed NICs as necessary
    How then does traffic get routed between these two subnets?  If RRAS has to be configured to do this where is the best place to do it, on the hyper-V host or on the virtualized domain controller?
    Thanks,

    Hi ,
    You can create an internal virtual switch and configure an IP for it (I assume it is 192.168.1.2/24) .
    After you enable RRAS in hyper-v host  there will be two gateways for different subnets  .
    " NIC 2 (hyper-V virtual switch.) = 192.168.1/24 - connects to ADSL internet router "
    The problem is here ,if  these VMs need to access internet .
    So , these VMs can not configure their gateway same as the IP of internal virtual switch , you may set VM's gateway as the ADSL internet router's IP meanwhile add a static route entry for every VM .
    Please refer to the Syntax :
    route add -p 192.168.0.0 mask 255.255.255.0 192.168.1.2
    Hope this helps

  • Outlook doesn't want to connect with OSX Server on 2 out of 3 clients

    I have three computers on which I have installed Outlook 2011.  All three are running Mavericks.  On one of them, a MacBook air, I have established an outlook account connecting to my OSX server with no problems.  On the other two computers when I set the parameters the same way, I cannot establish an outlook account.  When I use Apple Mail on any of the three machines, I am able to establish accounts for iCloud and  the OSX server with no problems.  Can anyone point me to the source of this problem or a method for trouble shooting it?

  • Want to connect to client's server with ARD, and run ARD on the server.

    Hi, I have Apple Remote Desktop and use it to monitor, update and service clients servers. I also have client's buy ARD to use internally to access, update and maintain computers on the network.
    When I try to access/sign-in to a server with ARD, when it's running ARD, it will not connect.
    What is the proper way to ARD into a server and still be able to run ARD on the server to connect with and work on other computers on the local network?
    Thanks in advance.

    On the client server install of ARD, open ARD, select preferences, select security tab, and make sure "allow control of this computer when ARD is running" is selected.

    Hi @OHIMATAS,
    I see by your post that you are unable to network the printer to the Windows XP computer, but the Windows 7 computer is connected. I can help you with this.
    Make sure the Windows XP computer is connected to the correct network name, not a Guest network either.
    Print a configuration page to get the printer's IP address.
    Printing a Configuration Page.
    Try and access the printer's Embedded Web Server on the Windows XP computer.
    Type the IP address into your web browser's address bar. (Internet Explorer)
    Did it load the webpage?
    If you can't access the printer's EWS, then check the IP address on the computer to see if the first 3 sets of numbers match the printer's IP. They have to match to be on the same network.
    Go to start, type run in the search box, type in cmd, then type ipconfig.
    Check the IPV4 address.
    Now check the IPV4 address for the printer.
    Do the first 3 sets of numbers match?
    Try and ping the printer.
    In the same window, type ping printers IP address (space between ping and IP address)
    What are the results?
    Run the add printer wizard through printers and faxes, if you were able to access the printer's EWS.
    Please provide in detail the results if you are still having issues.
    Have a nice day!

  • My email account in Mail.app is IMAP, but when I delete emails, they don't delete from other devices connected to the mail server with IMAP. Deleted mail on other devices delete as normal from the server and thus from other devices as normal.

    MacBook Pro, late 2011 version. Up to date Mountain Lion.
    My email account in the Mail.app is set up as IMAP, but when I delete emails in the Mac Mail App, they are not deleted from the mail clients of the other devices that are connected to the mail server with IMAP. IMAP works perfectly between Windows Outlook 2010, iPad Mail App and Android default mail client. Deleted messages behave correctly, as in delete from one device and the mail is deleted from all devices.
    Having just tested in reverse order on the Mac; emails deleted from the email client on Windows, iPad and Android are not deleted in the Mac Mail App.  It appears that the account is behaving like POP rather than IMAP.
    Any advice on how to have IMAP work correctly on the MacBook Pro Mail.app?
    Thank you.

    Hi Csound1, thanks. The email host is 1and1.co.uk, however, i am going to fess up and make myself look like a plonker now -
    the email account in question was set up in Outlook as POP - stupid, stupid, stupid me, wasted an afternoon on this!  I have now changed the Outlook account to IMAP and Mail.app works perfectly - and looks much nicer than Outlook did.  Im in the middle of converting from Windows to a Mac, and still finding my way around the Mac
    The lesson learned, never assume - always double  check!  All my other email addresses with 1and1 are all imap, except this one, and it happened to be the first one I set up in the Mail.app. (bows head in disgrace!)
    Thank you anyway for attempting to help me!

  • My server has Two NICs ! I want to use one of the NIC for the internet and the other to a local Network .

    In my case ,  there is a server ( windows 2008  enterprise) . Instead of sharing the internet using the server .  i have done the following .
         i have 24 port switch which is connected with the modem (ISP Gave it to me).  My server then is connected with the switch .  the client pcs are also connected with the switch(d-link switch).
    my objective is to enable efficient way of file sharing from server for client pcs and also internet sharing at the same time for client pcs!
    my server has two NICs ! how to make the local network and internet work with out a fight!
    how could i achieve this ?  help me guys
    regards

     It really depends on exactly what the equipment from the ISP is. If it is a simple modem there is no point in connecting it to a switch. It needs to connect to a router.
      You can connect it to one NIC of the server and configure the server as a (NAT) router (with the other NIC connected to the switch).
      If either of the switches is actually a router you can use it as the NAT router and run the server on the LAN using one NIC.
