Startup network configuration dual homed

FRUSTRATION: 100% .. Over a month trying to startup network configuration dual homed .. MacMini Intel Dual .. System Preferences --> Network --> Two Locations (BuiltIn ether on the IP my router uses for the world www, smtp, dns, ntp, limited ssh 192.168.local.wired.fixed) and (AirPort for VNC, ssh for admin via laptop)
Upon reboot, I have o login back to the Mini keyboard/CRT to reset these two locations. I am NOT passthru routing.
Bad enough the CRT settings will ot start my 20in VGA till I restart the video on an old low-res monitor.
No where near ready to install the Server pack. Looking thru the web stuff, there are Unix like files (missing) to force the addresses and default route. No ifconfigd found.
Where do I find a netconfig, rc.conf or like files to force the Mini (OS 10.4.7) to come up with my two interfaces and default route?

This is the wrong forum for this topic, but I'll assist.
Without configuration sync enabled, you would have to configure both Nexus 5K exactly the same for the FEX port before traffic will forward.
Configuration sync would help you in only having to configure it once, but I have had mixed results using configuration sync so I tend not to use it in my deployments.

  • Configuring Dual-homed servers for redundancy to 6509s

    I am looking for assitance in properly configuring dual-homed servers for redundancy to two CatOS based 6509s. My search for information on how to do this has been unsuccessful to date, so any help you can provide would be most appreciated.
    Do I need any special hardware/software on the 6509s and/or on the servers?
    Thanks, in advance.
    John

    A lot depends on the kind of servers you have and the NIC teaming algorithms they support. Usually two or more NICs can be teamed in either a fault tolerant configuration (with one primary NIC) or in transmit load balancing configuration. Both these configurations allow the NICs to be connected to separate L2 switches so in case your servers do support such kind of teaming all you need is to have both NICs in the same VLAN and ensure L2 connectivity between the Catalyst 6509s. I recommend you research this from the server perspective also and like everything else test it before production deployment.

  • Dual-homed server to two Cat4948 switches

    Hello everyone,
    I have a picture above which I want to realize. The main point is a dual-homed server connected to two switches.
    At server OS needed to configure NIC teaming which uses LACP. But how I can do it at Catalyst 4948?
    Which technology I able to use to multi-switch etherchannel?
    If I need one more link between Cat4948, then I can do.

    The exact load sharing options available to you will probably depend on the server type / vendor. The settings are applicable to the Network Adapters but you usually use the configuration utility provided by the respective vendor. I would suggest you do a quick google search on your particular server model. An example is:

  • IronPort ESA - HA and Dual Homing

    Hello, i have a customer that want to do HA and Dual Homing implementation. I want to ask what is the best way to implement HA for IronPort ESA? As i know the cluster configuration only used so the policy can be distributed equally. And what about dual-homing scenario? Is it supported with IronPort, and how do it works ?
    Regards
    Alkuin Melvin

    What exactly do you mean by multi-homing? Ironport email appliances support configuration of multiple interfaces (physical or vlan) , to which you can then attach Listeners (SMTP processes). You could thus configure your servers to receive or send email on multiple IP addresses, depending on your network config.

  • How to replace Nexus5596 with dual-homing N2K

    What is the correct process to replace a FEX parent switch with dual-homing fex?
    Traffic should not be interrupted.        

    Hi
    Do you have VPC between Parent Switches & are you running VPC on dual homed FEX fabric ports. ?
    If yes Below is the procedure,
    1)  boot the replacement switch without VPC, peer-links & FEX ports connected to it.
    2)  Make sure it has same Software version matches with the peer switch.
    3)  enable Pre-Provisioning for slots with appropriate FEX model.
    , here find the guide:
    http://www.cisco.com/en/US/partner/docs/switches/datacenter/nexus5000/sw/system_management/521_n1_1/b_5k_System_Mgmt_Config_521N11_chapter_0100.html#task_05BB53AD7AFB49CF9A8E4A5C6C37CB38
    So, on the replacement switch you will pre-provision the Fabric Extender and configure the ports so it will be ready when you add the module to the RMA SW.
    Please make sure you put the appropriate FEX model on the provision slot, otherwise, when connected it will not come Online
    Example, FEX 110:
    N5K(config)# slot 110
    N5K(config-slot)#provision model N2K-C2248T
    4) Now  keep all ports at Shut down state Then Configure Entire switch that includes FEX host ports, FEX Fabric Ports & VPC peer-link, VPC Domain Configuration.
    keep FEX host ports in shut state.
    5)  keep VPC Role priority on existing switch lower than , new switch
    6) Connect Peer-link ports to Peer switch & wait till VPC Comes up-
    7) Then connect Fabric ports from FEX to the pre-configured ports on replacement switch
    After it comes online Unshut FEX host ports.
    I got similar steps here as well

    Hi Glenyse,
    Did you find the answer to your question?  I have the same problem.  Or can anyone else help?
    My wife’s 2012 Macbook Pro has Yosemite and is using Wi Fi for the internet connection. 
    Every time, both on startup and awaking from sleep, a window appears on the desktop with a locked icon saying, “Networksetup is trying to modify this system.  Type your password in to allow this”.
    The window (which can’t be moved or dragged) shows the computer’s user name. The password has to be repeatedly typed in as many as 10 times and the highlighted ‘modify configuration’ box clicked before the window disappears and the computer then functions normally.
    Needless to say, this is driving my wife up the wall…    I would certainly appreciate information on how to get rid of this troublesome window!

  • BGP in Dual Homing setup not failing over correctly

    Hi all,
    we have dual homed BGP connections to our sister company network but the failover testing is failing.
    If i shutdown the WAN interface on the primary router, after about 5 minutes, everything converges and fails over fine.
    But, if i shut the LAN interface down on the primary router, we never regain connectivity to the sister network.
    Our two ASR's have an iBGP relationship  and I can see that after a certain amount of time, the BGP routes with a next hop of the primary router get flushed from BGP and the prefferred exit path is through the secondary router. This bit works OK, but i believe that the return traffic is still attempting to return over the primary link...
    To add to this, we have two inline firewalls on each link which are only performing IPS, no packet filtering.
    Any pointers would be great.
    thanks

    right... please look at the output below which is the partial BGP table during a link failure...
    10.128.0.0/9 is the problematic summary that still keeps getting advertised out when we do not want it to during a failure....
    now there are prefixes in the BGP table which fall within that large summary address space. But I am sure that they are all routes that are being advertised to us from the eBGP peer...

  • Network configuration on FC 3510

    Hello,
    I'm trying to setup IP addresses and hostname on a SE 3510 FC Disk Array.
    We have a dual controller configuration.
    I was able to configure the ip address and hostname using sccli on the upper controller.
    How do I configure the IP address for the second controller?
    I tried with a tip session, but on the second controller it gave me an error Network Interface was not found. I used Ctrl-W to switch to the second controller, the serial cable was connected to the upper controller.
    Thank you,
    Jacob.

    The network configuration is different to some of the other arrays:
    The 3510 only requires 1 IP address as only 1 network interface is active at any one time. Both controllers should be connected to the network if you're wanting to use out-of-band management.
    So, long story short, if you've already set the IP address on the active controller, you're done.
    HTH,

  • RDS Gateway Best practices Dual-Homed?

    Good Day,
    I am wondering what is a typical amount of time others see when end users launch a RemoteApp session that goes through the RDS Gateway.
    Our two RDS Gateway servers (entire environment is W2k12R2) seem slow to me. They are both Dual-Homed and with a Nic on the DMZ and Internal side of the network. Maybe I would be better off disabling the Internal Nics and reconfiguring the firewall rules
    so that everything routes through the DMZ nic?
    Steve J.

    Hi Steve,
    Thank you for posting in Windows Server Forum.
    Best practice for any server is depends on your environment scenario as you need to decide whether to place the gateway in DMZ or allow 443 to be opened to the internal network. Placing the RDS Gateway in DMZ is more secure, you can have more information from
    beneath article.

  • N5K - N2K Image Upgrade Single vs Dual Homed

    Hi,
    The upgrade distuptive behaviour is not explained well in the following documentation link . Especially about single homed FEX topology.
    http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/upgrade/503_N1_1/n5k_upgrade_downgrade_503.html
    1. I have just upgraded a dual homed Active / Active N2K to N5K environment as below. The downtime was exactly explained as above URL, just the time to reload the FEXs. Which was about 1.5 minutes or so...
    Or should we NOT reload all the FEXs almost simultaneously by manual command (as mentioned in the upgrade guide) in this topology, in order to minimize the downtime ?
    2.However I am curious if there would be any downtime in a single homed FEX topology as below. My guess is there would be just the downtime for the edge server to distribute the traffic to the other N2K.
    I guess if the downtime is really a biggy,  then the second topology is easier to manage.
    Comments area very much appreciated.
    Dumlu

    I am not able to see the images you attached, could you please try reinserting them?
    Also if I am understanding your question correctly, you are wanting to know if there will be downtime, if you upgrade a N5K with a 2K single homed. I assume you meaning something similar to this?
    If so, yes the single home fex would be reloaded per the document it states: "Upgrade the first vPC switch (vPC primary switch) -  during this upgrade, the switch will be reloaded. When the switch is  reloaded, any dual-homed FEX will not be reloaded.  Only singled-homed FEXs are reloaded. Servers connected to these  dual-homed FEXs retain network connectivity via the second (vPC  secondary) switch"

  • Dual-homed FEX

    Looking for some guidance with a problem. I have 3 Nexus 2248T switches dual homed to 2 Nexus 5672 in the core. (See Attachment)
    Problem: on one of the FEX I have an Exchange NLB cluster. Several of our systems that require POP3 mail to communicate messaging have experience connectivity issues (unable to send mail) and require the connection to be hard coded to one of the IP Address in a cluster server instead of the NLB address. 
    Configuration: I have not setup Spanning-tree on the trunk ports from the 5672s and am showing that BPDU guard is disabled for the edge ports.
    Nexus5672-1# sh spanning-tree summary totals 
    Switch is in rapid-pvst mode 
    Root bridge for: none
    Port Type Default                        is disable
    Edge Port [PortFast] BPDU Guard Default  is disabled

    Pathcost method used                     is short
    STP-Lite                                 is enabled
    Question: I am thinking I missed the "boat" on the configuration and need to include spanning-tree at the port level to correct the problem. Any advice please?

    You don't need spanning tree config at the FEX level.  You just need spanning tree on the 5762 devices to determine what device is the root and what device is the backup root.

  • Reducing the fex time for N2K dual homed to N5K

    Hi,
    We have N2K dual homed to 2 N5K. The N2K registers the fex with one of the N5K. But when one of the N5K fails it takes more than a minute to register with the second N5K.
    How can we reduce this delay so that there is minimum timeout between failover ?

  • Fabric Extender question to a dual-homed N5k

    According to latest release notes:
    http://www.cisco.com/en/US/customer/docs/switches/datacenter/nexus5000/sw/release/notes/Rel_4_2_1_N1_1/Nexus5000_Release_Notes_4_2_1_N1_1.html#wp144071
    "Support for a maximum of 12 Fabric Extenders dual-homed to a vPC Cisco Nexus 5000 Series switch pair and a maximum of 576 hosts connected to Fabric Extenders connected to Cisco Nexus 5000 Series switches"
    I have mixed mode so some of the FEX will only connect to one N5k despite the 2N5k will be vpc. Cisco calls this "Fabric extender straight-through topology". This is because I am running port-channel with VM on these particular FEX.
    http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9670/C07-572829-00_Design_N5K_N2K_vPC_DG.pdf
    question is:
    1. Can I assume 2148 is included per release notes?
    2. Can I have more than 2 ports in the portchannels in straight-through mode?
    3. Release notes show 576 host which is (12 max times 48 ports). I assume I can have more logical host meaning vm host via the port channels, right...?
    Thx

    Any Nexus 5000 can have a total of 12 FEX's connected to it physically.  If you have 12 FEX's in dual-homed mode, then that is the limit for both Nexus 5000's.  If you had 24 FEX's evenly distributed between the Nexus 5000's in straight-through mode, then that would be maximum in that configuration.  If you are mixing straight-through and dual-homed configurations, you would have to be within the 12 FEX per Nexus 5000 limit.
    The 2148 is the first FEX, so yes it is the focus of the release notes.
    The 2148 cannot have a local port-channel.  This is why you can only channel to a 2148 when using dual-homed (called Active-Active mode), one interface on each 2148, and it is tied together with a vPC configuration to make a port-channel.  The individual 2148's each only have one connection on them down to the server below.  The 2248 and 2232 do not have this restriction.
    As of 4.2(1)N1(1), 576 refers to host interfaces.  If your host has virtual hosts, you just need to make sure you are within the limit of mac addresses in the system, which is 16,000 (13,800 unicast).
