• Mac Mini - no Ethernet Interface

  Hello

  I have the Mac Mini 2011 model, and I've been using an Ethernet for some time, have not had any problems, connection worked perfectly until now. First of all, there is no internet connection, so I have just connected to wifi for a bit, then I went into System Preferences - network, where more ethernet it indicated "cable disconnected" even if the cable is connected. I checked that the cable is not the issue, work on other devices. So I have that if I just remove the ethernet interface with - button, and then add it again with the + button that would solve the problem. However, now ethernet interface does not even upward in option:

  

  I'm currently under OS X El Capitan 10.11.3.

  Please help resolve this annoying problem, because the ethernet port is the key for the speeds for me.

  Thanks in advance!

• Ethernet interface disappeared

  As I rebooted my laptop this morning, I didn't more wired Ethernet network. I have not installed updates yesterday, but yesterday it worked correctly. It is not a problem with the router or the cable, because it works correctly with the other laptop. The router detects when I connect the cable (the port lights) but the router has no ARP entry for the connection (only for wifi that I need to write this question). In addition, it still works the WiFi.

  Restarting the laptop does not help. I opened 'Network Preferences' and I removed the Ethernet network in order to recreate, but surprisingly, the 'Ethernet' interface does not appear in the list more (it is available WiFi, Firewire, Thunderbolt 1, Thunderbolt and Bluetooth PAN bridge). With the Network Diagnostics didn't help either. I also tried to test the equipment with the Apple Diagnostics (by pressing D when starting the laptop), but I did not need to start the diagnostics.

  It seems that the ethernet driver has been uninstalled or misconfigured.

  I have a Mac Book Pro (2011) with OSX El Capitan.

  Any advice on what to do?

  Thanks in advance

• TimeMachine and two Ethernet interfaces

  OS version 6.4.2 OS X 10.11.3 (El Cap).

  That ReadyNAS has two ethernet interfaces, which I had connected without adherence to the network.

  All Mac on the network would be fix and update the sparsebundle on the ReadyNAS for some time (two days for example) and then each machine would begin to complain that the destination does not exist. One solution would be to reboot the NAS and things would work for a while.

  How I solved this problem is to simply unplug one of the NAS ethernet ports and run on a single interface.

  I guess that there is a conflict in the NAS with Hello or other discovery services and some confusion about the interface gets introduced to the network. This seems to change with the times.

  I could possibly get a switch that supports the binding, but for now I would like to be able to run both interfaces if possible (I pay for them after all)

  Hi rawb1,

  Concerning the use of multiple network cards or adapters ethernet in your ReadyNAS system, here are some useful articles from NETGEAR that you can watch.

• Controller time real-time FieldPoint or Ethernet interface

  Good afternoon

  The first feature listed on the PS-2000 product page is:

• Stand-alone embedded real-time controller or on PC distributed i/o Ethernet interface.

Everyone was able incorporate a PS-2000 as an Ethernet on PC distributed i/o interface?  In other words, have the PS-2000 as a FP-1600 Act?

There are some discussions forum discussions that dance around the subject, but I found no really one who responds to her.

Thank you

Ed

Hi edlad,

After playing with a FP-2010 for a while, I think you need to install LabVIEW Real-time on the controller to make it work, even though you are technically not to use it because you are not running a VI/executable on the controller. Regarding your problem with the installation of LabVIEW 8.5.1 on a PS-2000, it is disturbing because it should not be a problem that at all. In fact, I have personally been able to install LabVIEW 8.5.1 on many FP of the 2000s. For that matter, I suggest reformatting of the PS-2000 of MAX and try again.

ThinkG: Regarding your question on the use of a PSC-2220 to connect with belvedere, I don't know because the support of Lookout is managed by our subsidiary in Shanghai by e-mail only. However, I don't know that you can use this second ethernet port to connect with another network (cFP-180 x) FieldPoint module using the FieldPoint drivers. Here are some good articles about this configuration knowledge base. I hope they are useful.

• Using TCP on the second ethernet interface

  Hello

  I use a PXI 8109 Pharlap module running.

  I try to use the second my PXI ethernet interface to send UDP and TCP packets. The main interface is used to manage channels Veristand.

  Here is the configuration of my two ethernet interfaces:

  -eth0 (primary):

  IP: 10.0.0.3

  subnet mask: 255.0.0.0

  -eth1:

  IP: 192.168.10.9

  subnet mask: 255.255.255.0

  For UDP, I have no problem, the packets are sent to the second interface as I want to. I think it works because there is an entry "network address" on the "Open UDP" VI so that the system can choose the right interface.

  For TCP, I use the VI "to open a TCP connection" but there is not that kind of entry. And it does not work: I suppose that the system tries to use the main interface, but it can route packets...

  For more information, my two networks is physically independent.

  Can you help me find out what is happening? Is it possible to use the TCP protocol on the second ethernet interface?

  Thank you very much

  Kind regards

• Difference between the series & ethernet interface.

  Hello world

  I have some doubts in basic foods.

  Q1: What are the differences between the interface series and interfaces ethernet.

  Q2: Can we use ethernet interfaces to put an end to a WAN connectivity like series. Why always we use interfaces series to connect the Wan.

  Please help me by answering these questions.

  !!!! THANKS IN ADVANCE!

  Hello

  Fast Ethernet card is one of the option for a higher speed T1/E1, other TDM options that can be offered are DS-3 and STM1 that can be offered on infra nominal basis as well. For example, you can subscribe for 10 MB BW on 45 MB access.

  The answer to your second question, is that there could be a possibility that you have subscribed for VPN (EVPL or VPLS) L2 or L3 VPN (MPLS).

  Woks of L2 VPN on labels VLAN and L3 VPN termiantes on a device of L3.

• How can I put wireless and ethernet interfaces together?

  I have a 877w router, and I'm trying to set up a wireless network.

  I have a bridged RFC1483 ADSL, so I ATM0.1 in a group of bridge, and then, I defined an interface BVI1.

  However, after you have configured the wireless interface, I noticed that my laptop is the IP address of the supplier, as if wireless had precedence on the BVI interface. Put the Dot11 interface in a separate bridge under VLAN1 does not seem to help either. I tried to put everything in the same bridge, but fast ethernet interfaces do not support address (how the British Virgin Islands work then, I wonder).

  What should I do? Use two VLANS separated? I wouldn't do that. Any help appreciated. Thank you

  Hey, thank you, that did it.

  So I followed the article. I guess I don't understand how the British Virgin Islands. Of the article, I thought them then were at the same level, i.e. all the right behind the ATM interface. I also thought that a BVI able to fill several VLANS. Now my next mission is to understand why I was wrong on both counts.

  Guys, thank you very much for the help. Now I'll try to better understand what I :-)

• of Ethernet interface input queue size/81/80 (max)

  Hello

  Anyone have the problem that the C1140 - K9W7 (or C1135) Gigabit interface

  sometimes "blockages" due to problems of queue (from what I understood it was the problems of queue)?

  I got this AP, C1140-K9W7 with IOS 12.4 (21a) JA1 and noticed that it did not

  any entry of packets to the interface, Gigabit, County of drop 0 but strangely the entrance queue

  information was that he had size 81 and 80 max... seems to me that the treatment of the queue

  code hanging somewhere...

  The output interface is OK however (the AP sends arp requests..).

  I did some research but could not find any information on this subject, also followed the

  steps to try to resolve what was causing this, without success [1]. The rating of IP traffic

  shows that the interface receives packets, but they are not under treatment and "not".

  droped too (at least the number of drop is 0).

  If I reboot the AP it works OK Yes... I can still access the console (via serial) and it

  in the case where there is no suggestion of procedure, is still in this State.

  Thanks for your time.

• cRIO-9114 don't reset the host.vi programming interface

  Hi, I use Labview 2009 with a target FPGA 9114 cRio controlled from a host PC.

  Host opens the target FPGA (open FPGA vi reference) and then executes a loop to write output voltages via the FPGA - target.vi in an analout 9264 module. Works very well.

  When the loop in the host.vi is stopped, I tried that reset just as method of FPGA interface outside the loop to restore the default values defined in the FPGA - target.vi the analog output voltages. However, the values are not reset, but remain at the last value in the loop.

  The only thing that works is by using the method of interface FPGA download instead of resetting one after execution of the loop.

  Any ideas why the reset function and/or stop does not work?

  Thank you very much!

  Can you post your code? I guess that the analog value is never sent when you stop. The program closes faster than analog writing. That would be my guess based on the way you have described.

• Crypto can be applied by entering ethernet interface.

  Hello

  We try to form a VPN tunnel between two routers connected by point-to-point link between two hosts on part and on the other. (host A to router LAN A to host b. router lan B). We have tunnel successfully implemented by the application cryptographic cards for two series of routers interfaces. Data from host a to host B by this tunnel formed on the serial interfaces.

  This is, what serial link toggle ISDN backup takes and data are transferred via ISDN link, as crypto is not applied to the ISDN data past unencrypted. To work around this situation, is possible to apply the crypto to fastethernet interfaces of routers, in this case the data that can go by series or ISDN, it will be permanently encrypted.

  The configuration is very simple.

  We establish the tunnnel as address serial peer, can we put peer as ethernet addrsss addrees and form the tunnel.

  We tried, but it doesn't work.

  Any link on cisco.com is much appreciated.

  Thankx in advance

  Hi Subodh

  You must apply the encryption on the BRI interface card too so that also your crossing of data through the IRB gets encrypted.

  I feel in this case, you must create another card encryption with similar parameters so that you can apply the same on BRI interface.
