Ethernet Switch Connectivity Test

Hi,
My application is to test the connectivity between two ports of the Ethernet Switch.
--> i have installed two LAN Card in PC and configured with 2 IP and connected 2 ethernet switch ports accordingly.
--> Need to send a data in one IP and receive the dada in another IP then compare it.
I have attached Block diagram of my application.
Please help me to solve this issue.
Thanks,
Sakthivel Muthusamy

You never want to have a switch between the modem and base station.
Reason....the modem only provides one IP address, it will be a matter of chance as to which device connected to the switch gets the Internet connection. If the base station happens to be the lucky guy, no other device(s) that are connected to the switch will be able to connect to the Internet.
Connect the switch to one of the LAN <-> ports on the base station and all will be well.

Seeking to fix this error: "Failed while adding virtual Ethernet switch connections."

I am getting the error below when trying ot make modifications to my Hyper-V.
I am trying to add a new Virtual Adaptor.
Hoping someone may have a suggestion on how to fix this.

Alex just a quick response to your advice re disabling AV, this did not work for me, after more searching the internet for a solution I found a post from 2013 where one poster offered the advice to go one step further, and it was to remove the AV package
completely, the package in question was KIS2013. I have KIS2015 and figured I would try it as I was getting a little frustrated with the constant failure to create a virtual switch.
Anyway, it worked for me, I removed KIS, rebooted, and the VS was created on the first attempt without any issue. So simply pausing/disabling the AV from within the AV program may not be enough, I suspect that some may work and others not, as in the case
of KIS. I wonder also if you disable the AV services at start-up if this would also work but I did not try it.
Anyway to other people experiencing this issue, I suggest disabling AV first as per Alex's advice, and if this does not work for you then suggest trying to remove the AV before doing anything more drastic like re-installation of OS as I have seen suggested
in more than one place.
Thanks
Mr Bee
--EDIT--
Just wanted to add, it is also worth 'excluding' any Hyper-V folders from the AV engine, I did not try this before removing KIS2015 so it may work without the need to remove your AV product, but on re-install I have now exluded the folders as suggest by
a few folks in various posts...

Ethernet Switch Connected to Time Capsule

I am trying to network my Home Theater equipment (WD Live TV, Samsung LED and Samsung BluRay--all of which have ethernet ports). I ran a standard cat5e cable from the Time Capsule base station. When that cable is hooked up individually to any of the devices, the device connects. I bought a gigabit switch (D Link DGS-2205) in an attempt to connect all three without running 3 separate cables to the Time Capsule. I get nothing.
I am not sure if I need to configure my network differently starting with the Time Capsule or if the I need to configure the switch or the devices somehow.
Any ideas? Thanks in advance.

You should not need to configure anything on the Time Capsule and a switch really needs no configuration unless you have a router. (I did not look at the manual for your D-Link).
You are running the ethernet cable from one of the LAN <-> ports on the Time Capsule to the switch, correct?
Once you have all 3 devices connected, are you powering everything down and then restarting?

Failed while creating virtual Ethernet switch. Failed to connect Ethernet switch port

Hello Folks
I am completely stuck with the configuration of my virtual networks. I have one logical switch left to add to one of my Hyper-V 2012 R2 hosts when I started getting the error below when I try to add logical switches to either Hyper-V Host. I have been using
the document. 'Hybrid Cloud with NVGRE (Cloud OS)' to implement the virtual networking. Basically using the exact configuration that is in the document. I have added the PA Logical Network and the Network adapters and added the logical switch for it to my
hyper-v 2012 R2 host and everything was fine. I am now trying to add my ISCSI Logical Switch to the host and this is the error I get. My other Hyper-V host I get this error for any logical switch I am trying to add. Can someone help me with this error. I haven't
been able to find any information about it.
Also a some quick info on tracing an error like this so I can figure out what is causing it.
Thsi is my configuration so far
So as far as I know everything is peachy untill the error below. Dead stop now
Error (12700)

notice your GUID? you may want to consider ensuring that is the same GUID associated in your database. Sometimes during data corruption theres a smidge of a chance your sql database kind of either pulls old guids esp if this was reverted to snapshot
without it being powered off etc.
I would try that first. then i would consider if you get to configure that with your current liscense associated with the host. I would need way more info to help any further

Connecting an Ethernet switch to the AE?

Hi,
I have a small wireless network at home with the following setup:
1. Airport Express (802.11n) + ADSL modem connected to the ethernet port.
2. Mac Pro (2008) w/Airport Extreme card
3. Mac mini (2010) w/Airport Extreme card
4. PC laptop with 802.11b/g card (serves as a media center)
5. iPod touch
Since the laptop sits just beside the Airport unit I would like to connect it with a cable, for a couple of reasons:
a. Its wireless card is slow and unreliable.
b. I'd like to use Wake-on-LAN features
Since the Airport Express' only Ethernet port (which I understand serves for both WAN and LAN?) is already in use by the modem, I was wondering if I can connect the modem and the laptop to a simple ethernet switch (I was thinking of this one: http://www.edimax.com/en/producedetail.php?pd_id=281&pl1_id=4&pl2id=23) which will then be connected to the Airport Express. Is this possible?

You would need to use a simple wired only router...not a switch...to do what you want. Reason...with a switch, your "modem" is connected to two devices at the same time, but it can only deliver one IP address. It will be a matter of chance as to which device, the laptop or the Express connects to the Internet.
If the Express connects, then you will have no Internet signal for the laptop. If the laptop connects first, then you will have no Internet connection for the Express.
A router will accept a single IP address and provide additional IP addresses so that multiple devices will be able to connect.

Local ethernet switch - can't connect

Hello All,
Is anyone having trouble trying to establish a connection to a local ethernet switch. I have an Asante switch running that I'm trying to connect my en1 port to (both have green lights) but it is still saying inactive in the System Prefs:Networking. I have manually set the IP, router, and subnet mask. Is there something I am missing, do I have to make an adjustment on my Asante switch for Leopard server to connect?
Thank you!

I needed to actually turn on the port by choosing Make Active in the gear icon drop down. They don't just activate like with Tiger server.

WIRED FAST ETHERNET SWITCH BY NETGear

Here is my issue and it may be answered best on another board, but here goes. I hooked up a Netgear FS605 Fast Ethernet Switch. I ran my cable connection through the switch out to my Airport and then onto my IMAC Desktop. It all flowed fine. I then ran a cable from the switch to our new ps3 in the basement which did not see the connection. Now I figured maybe my cable making skills are lacking so i testes to see if i had a signal using my laptop. I did not. SO I went upstairs directly to the switch took out a good E Cable and connected the laptop there and still no connection. So i am not sure if A the cable i ran for the PS 3 is bad, and B having a **** of a time getting the Etherenet Switch to be reconized on my LAPTOP. any ideas out there? Once i get the LAPTOP to see the switch i can then go and check my cable run.
Thanks

Have you tested the cable with network testing device to make sure the cable is ok?

Powerbook G4 can't connect via ethernet but connects via airport

We have a small office network connected to an Efficient Networks DSL router that's managed by our isp. The router has 4 ports and a linksys 8 port switch is connected to one of those ports. Another D-Link wireless router/switch is connected to another port.
2 i-macs connect without problem via ethernet cable. They are set to DHCP and get 192.xx private addresses. Both run 10.4.5. Another older imac running 9.2.2. also has no problems.
I recently purchased a powerbook G4 and it will not connect via ethernet to the Efficient networks router. At first it was connected to the linksys, so decided to connect it direct to the Efficient Networks router. With DHCP, it acquires a 169. internet address which is self generated (i.e. no real connection). I tried to give it a static private address (talking to the isp provider). They could see the powerbook but saw all zero's (presumable mac address). By the way the Powerbook works perfectly at home connected via ethernet cable to a D-Link router connected to a cable modem so it's not a physical problem. I even checked the ethernet cable I used in the office with another computer - no problem.
When I switch to airport in the office, the powerbook connects to the network and the internet. I get some strange warning messages showing the server's and the router's private ip addresses. I click ok, and the powerbook finds an unassigned private ip address. It's the only way it will work, but it causes problems, because I can't connect to one of the network printers. Speed also isn't great.
Can anyone give me advise how to proceed. I am no expert on this stuff so keep it as simple as possible.
Tks

Tim,
Thanks for your help. Here's what I've done before reading your e-mail. The D-Link DI-524 wireless router is connected to the Effiicent Neworks DSL router as you mentioned. One ethernet port of the EFF.Net. router is connected to the WAN port of the DI-514.
Because I have a D-Link router at home which works flawlessly with my powerbook, I decided to connect the ethernet cable of the powerbook to the D-Link which has 4 ethernet ports. Lo and behold, the powerbook acquired a private ip address and connected to the LAN and internet!
When I connected the powerbook direct to the Efficient Networks router, it could not communicate. I believe that there must be some software incompatibility between the powerbook and the Efficient Networks router. By connecting to the D-Link, the D-Link assigned an ip address to the powerbook, and it could connect to the server, lan, etc..
Only problem is that I have a Brother network printer that cannot connect to the powerbook. My powerbook cannot find it on the network. Because there is a linksys switch connected to the efficient networks router's third ethernet port, maybe as you said, going through the D-Link via DHCP (when the Linksys is also acting as a DHCP server, might cause this type of problem. What do you think?
As a final note, other imac G5's connected to the linksys switch (which then connects to the Efficient Network's router) have no problem connecting to the lan or internet and have no problem connecting to any of the printers. When I put the powerbook on that switch, I could not connect to the internet - i.e. whether connecting via the lynksys switch or direct with the efficient networks router - same results: no internet connection whether manually or via DHCP.
So the imac G5 has no problem with the efficient networks router but the powerbook G4 hits a brick wall. The G4 likes the D-Link router. I am concerned (and I will have to check this) that if I turn off the dhcp server feature from the D-Link, that whatever software issue crops up between the powerbook and the Efficient Networks router, will rise up again, because the D-Link will act like a simple switch (just like my linksys switch), and we'll be back to square zero. In any case, no harm in trying. This may be the cause of the Powerbook not seeing that Brother printer (even though it sees another printer and other macs).
Having spent hours reading about network problems, I think it's safe to say that macs have problems with certain routers. Why a G5 works and a powerbook G4 doesn't is beyond me, but clearly software must play a role.

How can I connect airport extremes using a wired-switch connection and have roaming capability?

My goal is to have 2 airport extremes and 1 timecapule connected via an ethernet switch so that I can enable roaming. I have no problems connecting them wirelessly where I create the wireless network on a primary airport wireless then add the others "extending" the network. However, if I attempt to do the same thing with a wired connection everything stops working (no connections from any airport). Here's the topology I'm trying to achieve. I believe my problem relates to the switch and the fact that I am serving up DHCP from a separate server. Is there a way I can achieve this (or similar) type of configuration? Thanks in advance.
BTW, I have read the various documents on the roaming network topology but none seem to be a match to this.

To answer your question, yes, if I _only_ have the main "create wireless network" airport connected/wired to the switch, everything works correctly.
OK, got that.
Also, if I have each of the 3 airports/timecapsule "create wireless network" using the same ssid name and passwd/protocol, everything works correctly (but of course, no roaming under this scenario
Sorry, you have me confused on this one. When the AirPorts are all configured to "create a wireless network", use the same SSID, security and password, and all AirPorts are in Bridge Mode........that is the exact definition of a "roaming" network.
Not sure what you mean when you say "no roaming" in this configuration.
Also, if I have the main "create wireless network" configured and have the 2 other airports "extend the network" and _not_ have them connected via the ethernet cable, everything works correctly (wireless airport interconnection)
That is correct.
However, if I plug the 2 other "extend the network" airports into the switch via ethernet, all connectivity shuts down.
This is not a correct setup. The "extend" setting on the AirPort assumes that they will connect using wireless. If you then try to connect an Ethernet cable to an AirPort that is expecting a wireless connection, that will result in a big feedback loop and effectively crash the network.

Can I use an ethernet switch to add a "pogoplug" device to my Airport express router? Or do I need a different router?

I have an airport express router and decided to get a "pogoplug device" (cloud service to store files etc.). It requires to be connected to router per ethernet but I realized too late there is only one ethernet connection in the router. A friend suggested I get an ethernet switch but it still doesn't work...Do I need a new router?

Then, unfortunately, no as the single Ethernet port of the AX needs to be connected to the Ethernet port of your Broadband modem.
One option is to get another AX, and then, configure it as a wireless Ethernet bridge. It would connect to the first AX by wireless, and then, you can connect the PogoPlug to it.

Do I need an ethernet switch or new router for IP camera setup with old Airport Express

Hello,
I am trying to setup a third party Foscam IP camera to my network so that I can ultimately use it as a baby monitor, and am having some difficulty. I currently still have an old Airport Express (with one ethernet port only). This is preventing me from setting up the initial camera because I don't have another ethernet port to plug it in to on the router. I am wondering if I can just buy an ethernet switch and have it "split" the ethernet from my modem to both the camera and the Airport (I do need to check with my ISP provider if they give me two separate IP address... but if they do, would this work?).
I am fairly sure however, that my ISP provider (comcast) only provides one IP for my account. Does this mean I would have to buy a new router altogether with more than one ethernet port on it or one with a WAN port? Would I, in this case, have to plug the modem into the WAN port on the router, and then the camera to one of the ethernet ports on the router?
I consider myself fairly tech savy, but when it comes to routers, IPs, LAN, WAN, etc. I get a bit lost. This has been creating quite a headache for me and any help would be appreciated! Thanks in advance!

Sorry, but this won't work as the modem expects only a single device ... either a computer or a router to be connected to it. Unless your modem is actually a combination modem & router or gateway device, then you would need a different router to solve your networking problem.

Home Hub 3: ethernet & wireless connections from i...

I have a perplexing problem whereby the functionality I get from my Home Hub 3 is different depending on whether my brand new iMac computer running MacOS 10.7.2 is connected wired (i.e. using ethernet) or via wireless.
The functionality difference has shown itself to me in the two scenarios below. It's a problem to me because the problems occur when the iMac is connected via ethernet and I want to use ethernet to connect my iMac. If the wireless connection to the iMac was as reliable as everything else on my network (mac laptops also running 10.7.2, windows 7 laptops, iphones, ipads etc) I would be content to use wireless. However, the iMac frequently drops the signal requiring a wireless on/off to get it back. I'm tending to hold the iMac responsible for this and await an Apple fix, although having changed the security setting on the Home Hub 3 to WPA2 only and set the channel to channel 4, the wireless dropouts are much less frequent, without these changes it drops the signal every few minutes. Any input on this would be gratefully received.
I want wired for connection reliability (and speed), but I have a two situations where I get more functionality out of my network if the iMac is connected via wireless. A classic case of being caught between two stools.
Scenario 1
I have a WD MyBook Live NAS drive attached to the Home Hob 3 via ethernet with the intention of using it as a Time Machine backup disc for the iMac and to be a shared drive for our macbook and windows laptops. All seems fine at first with the iMac connected via ethernet, the browser can see the NAS drive and set it up etc, but Time Machine will only see the WD MyBook Live if wireless is switched on.
Scenario 2
I have an HP 5510 wireless printer and set it up and HP software installed on the iMac. With the iMac connected to the Home Hub 3 via ethernet printing is fine, however, scanning doesn't work, the scanner and iMac cant see each other. With wireless scanning is fine as well as printing.
I haven't wanted to mess with it all any more, Ive spent hours going through the HP software, the WD software, the router as well as the network preferences on the iMac. It's not making make sense. Anybody who knows what's going on here would be a genius in my book!

Hi mja, Apologies but I'm not the expert you're looking for, but a couple of my experiences may be of interest. I've got a WD my book running as a networked back up drive. A while back there was an update for a "USB" connected hard drive (which mine is definitely not) - this confused my PC -- wouldn't let it close down amongst many other symptoms --with great difficuly managed to disable the driver and sanity was restored. The other problem involved a print server that has a static IP address -------- my HH3 sometimes gives that IP address to other items on my network --------- this stops the printer working. Apologies if this post is not formatted correctly, I'm using an iPad --- not by choice,, All the best Michael

Can't Connect Via Wired Ethernet Broadband Connection

Replaced a Westell 7500 with a DSL-N10 because of constant disconnects. The Westell had no problem connecting via the wired ethernet broadband connection which I switch to when I need to improve buffering for videos. The DSL-N10 won't connect and reports "Error 651 Modem reported a problem". I reconnected the Westell to determine if there was a problem but it connected to the wired connection immediately. Question is do I need to change or add a setting in the DSL-N10 to get a wired connection or is this something I need to conract Verizon support about?

Do I need to buy an ethernet switch that has a WAN port

I want to buy an Aiport Express to handle a WiFi only iPad and an old PPC iMac with 10.5.8 on it that has no WiFi card. The iMac gets on the internet from a cable plugged directly into its ethernet port (using DHCP). The cable comes off an antenna at the front of the cottage. A signal hits the antenna from a broadcasting tower about half a mile away.
I need to buy an ethernet switch for the Aiport Express to handle both the iPad wirelessly and the wired iMac. Does the switch have to have a WAN port or can I buy one with five LAN ports?
Message was edited by: Roy Vincent. Spelling error

So here's what I am planning to do. I get myself an ethernet switch. I plug my cable from my antenna into it. I run a cable from one of its five ports into my iMac. I run a cable from one of its other ports into my Airport Express. I configure the Airport Express in Bridge Mode. Now my wife can connect to the web wirelessly using the iPad and I can connect using the wired iMac --- and we can do so at the same time and indpendently of one another. No?
Sorry, but no.
You only have one IP address. With a switch feeding two devices, it will be a matter of chance as to which device gets the IP address.
The other device will not be able to connect to the Internet, since a switch cannot "split" the connection.
Instead, you need a simple wired router to "share" the public IP address that you receive. In turn, the router distributes "private" IP addresses to devices on your local network, so each device will be able to connect to the Internet.
As I mentioned, a switch cannot perform the functions of a router.

TC not seeing devices attached downstream via a ethernet switch

I have a number of switches in my home network and for whatever reason the TC is not seeing the devices downstream. I assume the TC works like every other router in existence and should be just fine working with ethernet switches. The switches work great on my old buffalo wap/router and if I turn off the buffalo wap/router, move the ethernet cables to the TC (reboot TC, not reboot doesn't matter) all the network devices go kaput.
Any suggestions would be great. I've tried everything turning TC off/on. Turning switches off/on, turning switch attached devices off/on. Nothing works. Plug switch ethernet cables back into the buffao wap/router and everything shows up just fine.
Stumped.

There are some issues which have popped up with the TC and some routers.. particularly that the WAN connection is not working correctly.
Try using one of the LAN ports on the TC and see if that helps.
Also open the Network utility in the computer and run the netstat scan .. it looks like this.
Locate the TC on the computer that is having issues.
Then ping it.. use the full domain..
eg in terminal mine is ping tcgen4.local
I think you should rename the TC to all smb names.. ie short, no spaces pure alphanumeric as it simply works better.
Then if the TC shows up in the ping, mount the hard disk manually,
In finder, Go connect to server and type
AFP://TCname.local (use the full domain name of the TC from the netstat scan).. or use the IP you get when you ping it.. although that is going to keep changing unless you can lock it.
