Support Redundant NIC cards in a HP server

Hi
I would like to connect a HP server with two NIC cards (for redundancy) to two CISCO 2970 switches.

What I have to configure from the Cisco switches site in order to avoid ARP problems?
Thank you for your support
Stelios

Stelios,
We have had issues when trying to load balance between the NICs. when in active/active, the virtual MAC reflects in both the connected switch ports, and the packets tend to loop between the ports. There will be a lot of Spanning Tree TCNs generated, which can shoot up the CPU. We had a 4507R with SUP IV, which got loaded to 70% when doing load balancing. when we made it active/standby on the NIC, the CPU came down to 1 %...
so just be careful on this. best way of doing it is active/standby
hope this helps.. all the best.. rate replies if found useful..

2 NIC Cards in PowerMac G3 Server running OS X Server 10.3?

Hello all,
I have installed a D-Link PCI Network Adapter, Model #DFE-530TX+, into one of my G3 Servers (Blue and White - Yosemitie) running OS X Server 10.3.
I booted and then installed the driver provided on the vendors CD and then rebooted. I get an error at desktop saying that the driver cannot be used because it was installed incorrectly, although I followed D-Links instructions to the T.
I visited D-Links website and there is a different driver available for Mac OS 10.2x. When I install this one, same error.
Apple System Profiler does not show that there is a card installed in the respective PCI slot. I have tried both remaining slots.
Is there something obvious that I'm missing concerning installation of a secondary Ethernet connection in this machine? I have been told that OS X Server 10.3 doesn't need the driver installed at all, it should just pick it up.
Thanks for any help you can provide.
PowerMac G3 Server-Blue-and-White

A tech friend of mine suggested that I run the MacOSXServerEssentials.pkg located on Disc #2 of the OS X Server installation discs. Since the D-Link card functioned under the client version of OS X 10.3.9, if I ran the OS X Server Essentials package and upgraded a client to a server, it should retain the PCI card information. I tried to run the package and was told that I needed to have a minimum of OS X 10.3.9 client installed. I had not installed the Combo Update, therefore, I only had OS X 10.3.2 client installed. Once updated to 10.3.9 client, I ran the OSXServerEssentials package. Once complete it did not ask for a restart and was still booted into the OS X 10.3.9 client version. I did restart and am glad to report that I am now running OS X Server 10.3.9 with two NIC cards on a PowerMac Blue-and-White G3.
Thanks again for your suggestions,
Kyle

Redundant NIC in MCS-7825-H1 Server

Guys,
Do you now the procedure how to run the on-board dual NIC and worked as an active and standby in MCS-7825-H1 server from HP.
Do I need a third party software? Do I need to do any configuration in the switches or ONLY in the server?
Please be advised.

IP Failover between nic cards, not servers

This maybe a very simple question, I just haven't found the answer to it...
Our Xserve's are running on a Cisco switch and a switch port for the primary NIC card of one AFP server recently failed.
While the server had both cards connected to the switch and the second NIC card was live, the users lost connectivity to the internal server address (internal DNS) as is was pointing only to the primary IP address of that server.
This makes sense as there was no mechanism to tell the server to start using the secondary IP address.
We are now planning to connect all secondary NIC's to a second switch for both the LAN and the DMZ (VLANs) for better redundancy.
The DMZ uses IP addresses only due to port forwarding.
My question is now what is the best way to continue services on a secondary NIC if the first NIC fails.
Add a new DNS entry for the LAN? If so, how? Just enter the secondary NIC IP with the same server name?
Use FAILOVERBCASTIPS for the DMZ?
IP Failover works great between machines, but can the server send heartbeat messages to itself (example: FAILOVERBCASTIPS="NIC1-IP NIC2-IP")?
Is there any way to maintain the mount status of AFP volumes during the switch of IP's (since it's still the same machine)?
Thanks in advance for your help!
Xserve G5 Mac OS X (10.4.3)

Since you're using Cisco switches and are already familiar with VLANs, your simplest solution would be to use link aggregation to create a trunk between the Mac and the switch using both the NICs, then configure VLANs so that both subnets use the trunk interface rather than the physical interfaces.
That way traffic for either IP address can traverse either NIC, and you get automatic failover (thanks to link aggregation) should either NIC fail.
Note that this will only work if you're connecting to the same switch. If you have 'internal' and 'external' switches this won't work without some re-architecting of the network topology.

LYNC EDGE Server NIC Card Setup

Hello Guys,
I need Your help about setting up the NIC on my EDGE server. I already gone through the article about Set Up Network Interfaces for Edge Servers. as I understand there
are 2 NIC required on each EDGE server (1 Internal facing 7 another 1 is External facing). I just wanted to confirm is there any option to do this with only 1 NIC card or can we configure EDGE with 1 NIC only.?
Thanks in Advance.
Rishi Aggarwal
Regards Rishi Aggarwal

Possible? Yes, I do this on occasion against recommendations and best practices for companies who simply can't or won't set up a second DMZ (please don't split the NICs between your internal network and DMZ, it's just bad security). Everything
mostly seems to work just fine. But, recommended and supported? No.
Here's an article from David Paulino who's also been through it:

Server 10.3.9 - Three NIC cards - Route between Three subnets

I have a panther server with three nic cards, each one connected to a different network.
xx.xx.1.x = private intranet used for storing video files- Has a DHCP server
xx.xx.2.x = company intranet used for internet access-
xx.xx.3.x = editors intranet
I have a NAT set up to forward network activity from the .3 to the .2
But the editors (.3) also need to access .1.
Is there a way to connect the .3 to the .1 network through the server?
Any help would be greatly appreciated.
Here's a picture to show what I'm trying to say.
http://www.kbdiondemand.org/client_files/routing.png

Here is my newest routing table. I cleared everything out and started over.
I have NAT enabled and it is working, but I removed the private address.
http://www.kbdiondemand.org/client_files/routing3.png
I'm starting to wonder if I need to create a divert rule in the firewall. NAT has a firewall divert rule to send traffic to the NAT service.
So far, I haven't gotten the syntaxt correct for creating the divert rule. The error message is the port is incorrect?
I haven't found the information on any of the panther server books out there. They shy away from using the server as a firewall or a router.
excerpt from Essential Mac OS X Panther Server Administration
Of all the things that a packet filter can do, Apple seems to have some pretty specific things in mind for the Firewall service in Mac OS X Server. Panther Server's Firewall service is targeted at protecting the server on which it is running. Configuring a firewall for this purpose is very different from configuring a firewall designed to sit at the border between a network and the Internet. Mac OS X Server is simply not well-suited for the tasks normally performed by a dedicated firewall.
For example, Mac OS X Server needs to be rebooted for things like software updates, and does a fairly poor job of routing packets during the reboot. Surely you could configure Mac OS X Server as a router and then never touch it so that it wouldn't have to be rebooted, but that means no software updates. Just because Mac OS X Server can act as a router; that does not mean it's the most cost-effective or functional solution. Trying to shoehorn Apple's Firewall service into performing duties that it wasn't intended to provide is generally not a good idea.
Apple also includes a Network Address Translation (NAT) service that works in conjunction with the firewall. This service could be used to provide Internet access to a workgroup by allowing the workstations to share the server's IP address. While the NAT service does work, better results may be found with the average $40 NAT router. The bottom line is that it's a very good idea to use dedicated network hardware, and not a personal computer, to perform critical network functions like routing. This reduces network downtime due to computer maintenance such as software updates.
I will focus on using Apple's Firewall service for protection of services running on our server, and not to do routing or NAT for other computers.

ISE redundant NICs

Hello All,
does somebody know or point me how to configure redundant NICs on ISE Appliance SNS-3495-K9?
There can be only configured rudundant mode for CIMC, but not for the rest. I want to use Etherchannel or Bonding active-standby, to have the appliance connected to switches for more redundancy.
I haven't found anything like this in documentation and I cannot believe, that Cisco will not support this feature on theri appliances.
Thanks!
Karel

Hello,
the only document I found regarding the NIC redundancy is as follows:-
Step During boot up, press F8 when prompted to open the BIOS CIMC Configuration Utility. The following screen appears.
Step Set the NIC mode to your choice for which ports to use to access the CIMC for server management (see Figure 1-3 on page 1-3 for identification of the ports):
–Dedicated—The 1-Gb Ethernet management port is used to access the CIMC. You must select NIC redundancy None and select IP settings.
–Shared LOM (default)—The two 1-Gb Ethernet ports are used to access the CIMC. This is the factory default setting, along with Active-active NIC redundancy and DHCP enabled.
–Cisco Card—The ports on an installed Cisco UCS P81E VIC are used to access the CIMC. You must select a NIC redundancy and IP setting.
Note The Cisco Card NIC mode is currently supported only with a Cisco UCS P81E VIC (N2XX-ACPCI01) that is installed in PCIe slot 1. Refer to the following section in the Cisco UCS C220 Server Installation and Service Guide: Special Considerations for Cisco UCS Virtual Interface Cards.
Step Use this utility to change the NIC redundancy to your preference. This server has three possible NIC redundancy settings:
–None—The Ethernet ports operate independently and do not fail over if there is a problem.
–Active-standby—If an active Ethernet port fails, traffic fails over to a standby port.
–Active-active—All Ethernet ports are utilized simultaneously.

This is pretty slow, isn't it? I think the NIC card on this server is
due for an upgrade. I'm looking at the intel pro server nics.
Any other suggestions? I'm looking for a nic card that is on the HCL

Do I need (or do I even have) a NIC card? Modem works, comp not responding

Hi All,
Recently we have been experiencing connection problems with our cable modem and Mac. We've had our cable company out several times and I finally believe they have resolved any problems on their end.
Currently all of the cable modem lights are on (normally indicating we should be able to connect) and we are still not connecting. During a phone call to one of our cable techs he asked me to pull up System Preferences and click on Network. Upon doing this I then,under the "Show" drop down menu chose "Network Status". He and I were both surprized that the only thing that showed up in the dialog box was Internal Modem. There was no "Built in Ethernet" which is how our modem is connected to our Mac. He said that Built in Eternet should be there and that I need to get a new NIC (Network Interface Card) to resolve the problem so that the computer can communicate with the modem. Makes sense to me.
My question is this: Is there such a card for a Mac or was he referring to a PC type of card that performs that function. From my converstion with him he is obviously somewhat conversant with Macs (or had good scripts,prompts to read from) so I left our conversation thinking he knew what he was talking about. Is this a piece of hardware or software? I got the impression from him it was a piece of software that needed to be reinstalled. Lastly,where would I obtain the software/hardware?
Sorry about the long post. Any help will be greatly appreciated.
Cheers,
Vance

G4 400 mghz processor Mac OS X (10.3.9) 512 ram

Both of the G4 Macs you mentioned have built-in Ethernet on the motherboard. They would not require a PCI card to support this function unless the built-in Ethernet hardware on the motherboard were defective (this does not happen often), or you wanted to run much faster than the speed provided by the built-in Ethernet (not generally needed unless you are using a File Server at your location).
You already have a top-notch Apple brand Ethernet interface. Do not let your ISP talk you into installing a different PCI-slot NIC card unless you are certain the motherboard Ethernet is defective.

Add secondary NIC Card to existing VM

Hi,
I created some of VMs in Azure and four VMs need to have secondary NIC card, How can I add secondary NIC card to existing VM. I found some post that it cannot add NIC card to existing VM and need to add during VM creation, is it true ?
How many NIC card supported per VM ?
thanks
Keith

Hi,
Multi-NIC VMs must be in created in Azure virtual networks. Non-VNet VMs are not supported.
The current release does NOT support adding or removing NICs after a VM is created. Multi-NIC can only be applied when a VM is created.
The vmNICs must be added at the time of virtual machine creation. If you have an existing virtual machine that you want to add vmNICs to, you'll need to delete the virtual machine while keeping the VHDs and then create a new virtual machine using the existing
VHD while adding the new vmNICs as part of the provisioning.
The table below lists the numbers of NICs corresponding to the size of the VMs:
VM Size (Standard SKUs)
NICs (max allowed per VM)
A3, A6, D3, A8, G3, D12 (4-core, except G3, A8)
2
A4, A7, A9, G4, D4, D13 (8-core, except G4, A9)
4
All other sizes at this time
1
In order to Configure Multi-NIC VM, refer to the below mentioned steps:
Select a VM image from Azure VM image gallery:
$image = Get-AzureVMImage -ImageName "a699494373c04fc0bc8f2bb1389d6106__Windows-Server-2012-R2-201408.01-en.us-127GB.vhd"
Create a VM configuration.
$vm = New-AzureVMConfig -Name "MultiNicVM" -InstanceSize "ExtraLarge" -Image $image.ImageName –AvailabilitySetName “MyAVSet”
Create the default administrator login.
Add-AzureProvisioningConfig –VM $vm -Windows -AdminUserName “<YourAdminUID>” -Password “<YourAdminPassword>”
Add additional NICs to the VM configuration. There are several things to note about this:
>> The configuration of the “default” NIC is not set through this cmdlet. Please refer to Step 5.
>>The SubnetName must match one of the subnets in the intended virtual network.
>>The Name parameter must be unique within the same VM, but does not represent the names of the NICs inside the VM.
Add-AzureNetworkInterfaceConfig -Name "Ethernet1" -SubnetName "Midtier"
-StaticVNetIPAddress "10.1.1.111" -VM $vm
Add-AzureNetworkInterfaceConfig -Name "Ethernet2" -SubnetName "Backend"
-StaticVNetIPAddress "10.1.2.222" -VM $vm
Specify the subnet and IP address for the default NIC.
Set-AzureSubnet -SubnetNames "Frontend" -VM $vm
Set-AzureStaticVNetIP -IPAddress "10.1.0.100" -VM $vm
Create the VM your virtual network. Note: The VNet that you specify here must already exist (as mentioned in the prerequisites). The example below specifies a virtual network named “MultiNIC-VNet”.
New-AzureVM -ServiceName "MultiNIC-CS" –VNetName “MultiNIC-VNet” –VM $vm
Hope this helps !

How to set up set which NIC card to use for multicast?..

 One more thing,
 Can anyone one tell how to search for bugs (ISSUES) in weblogic. I am looking
 place where I enter ISSUE number and should get the detailed description of bug/issue

 Thanks Kumar, I'll try this.
 Does this -Dweblogic.interfaceAddress used only for multicast. Or this is also
 used to talk to AdminServer?.
 The other problem I am facing is when I restart the AdminServer in recovery mode
 it's not finding my WebApp servers, because my webapp servers are on public network
 and my admin (management) server is on private network.
 please look at http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=article&group=weblogic.developer.interest.management&item=1217&utag=

Having 2 NIC Cards

I have installed a second network card in my power G4 and I need to configure this card with a static IP; however, there is no where to do this (or at least I can not find it). I have the on board network card configured and working. Any suggestions?
I know if I was running os 10 then I could use UNIX commands to do this however I can not afford to do this at the present time.
Thanks
Power g4 Mac OS 9.2.x

Hi Manikandan,
You can use two network cards but if you installed B1 when this two network cards has been configured to enable, the B1 application run will have slow performance. So, you must disable one of network cards, restart the B1 server and run the B1 again.
If you need the NIC card that is already disable, you can enable again. It won't give slow performance.
my answer is quoted from SAP note 1135705:
SAP Business One takes too long to log on users
Symptom
SAP Business One client (not installed on the same machine as the
license service) might take several minutes to log you on successfully due to a delay in establishing a connection with the license server.
After logon, SAP Business One functions as expected.
This is due to the fact that the server or PC on which the license server is installed has more than one network card, or there is a dial-up & VPN interface-configured server.
Note: This can happen when you install the license service on a machine with more than one network card ALREADY installed.
Installing additional network cards on a single network card machine with a license service already installed might not produce this issue.
Other terms
SAP Business One, slow, login, log-in, delay, license, server, NIC, VPN, connection.
Reason and Prerequisites
Application error.
Solution
This issue is a candidate to be resolved in a future release.
Until then, you can use one of the following workarounds:
Disable additional network cards in the Network Connections. Also make sure there is no dialup interface or VPN interface set up, and restart the server. Note that you can re-enable the additional network card after the restart. This will resolve the issue until the next restart.
Install the license server on a machine with a single network card.
Disable all network cards, restart the license server and then enable the network cards again.

3-Com NIC Card Networking Problems on Solaris 10 (x86)

Hi,
I have Solaris 10 OS installed on a PC. I am having trouble getting my machine to ping other machines on the same network. I have executed the following commands:
#ifconfig elxl0 plumb
#ifconfig elxl0 192.168.100.181 netmask 255.255.255.0 up
When I try to ping another machine on the same lan, I don't get a response. I have even did a the sysconfig command and reconfigured my networking and it still does not work. I have tried different network cable as well. I have looked in the master file. I see the driver for my NIC, so I know it is supported by Solaris 10. Can anyone help me?

Here is some more info on my problem and a couple of things I have tried to do to resolve the issue :
I executed the command "prtconf-pv". I found information on my NIC Card, which is a 3-Com 3C905B-TX Etherlink XL 10/100. I found my vendor id - 10b7 and my device id - 9055. I then checked "driver_aliases" file to see if I could find an entry in this file and I did see my vendor id and device id. I would then conclude that Solaris knows my PCI vendor/device-id combination and maps them to elxl driver.
I have also tried a different cable that i know works and still nothing.
I also found from research in Sol. 10 that there is file in addition to hosts, hostname.elxl0, defaultrouter that has to be modifed. That file is ipnodes. I checked the file, and my ip address / hostname is noted in the file. Is it possible I have a bad NIC? I thought about swapping it out for another one that I know works, but it is an onboard NIC. Well, if anyone has and additional info, I would greatly appreciate it.
