We have a standard rule to team NICs on all of our physical servers.  However, the servers that host our phone software have a license tied to the MAC address of the NIC.  So, if we team the NICs, how will that impact this license if the primary NIC fails and the secondary NIC picks up?  Will the MAC address stay the same?  Will it change?

I'm asking because our phone tech is telling us to unteam the NICs and that will break our dual fabric redundancy we have set up in the switches.  

Can anyone shed some light on this?

ZipGrep is a utility that can list and search zip (.war, .ear, .jar, etc) archives for text patterns, without the need to extract the archive's contents.

One of a set of tools we're offering as a way to say thank you for being a part of the community.

Just wondering if anyone knows if there is a application and/or software that is available out in the market that can view all the different types of video cameras from vendors such as Cameleon, Enudra (Pelco), Exacqvision for example. There are others as well.

Probably just a generic software/application or something that is compatible with most vendors.

Thanks in advance,
Hello EE,

I am working on a network drive migration task and all has been going well with this command which will copy source to the destination and keep all the permissions\ACLs intact and gives me a nice log file to review the results. This command does not mess up anything on the source but will mirror it to the destination which is what I want for time being:

robocopy "\source-server\share\folder" "\destination-server\share\folder" /zb /MT:32 /mir /copyall /dcopy:T /V /tee /LOG+:C:\temp\robocopylog.txt /r:0 /w:0

All is well :-) Until I realize that I have tiny window for the final copy before full cutover to the new storage.

Problem: command above is taking close to 31 hours to run for 9TB of data and my cutover time frame is only about 12 hours. I re-run the command every 48 hours to check for changes to the data on source to update the destination and it appears there are millions of small files which are slowing down the copy.

All the data is there just want to keep the destination up to date with new robocopy command and slim down the time without jeopardizing the data or permissions\ACLs.

I have narrowed down a couple folders I could exclude from these subsequent copies to shave down the 31 hours to roughly 9 hours by reviewing the data.

I have been trying out the /XD switch and cannot get it to work.

Here is a example of the /XD added to the command;

robocopy "\source-server\share\folder" "\destination-server\share\folder" /XD …
When I want to create a new virtual machine I get the following error:  The portgroup for Network adapter 1, VM Network, could not be found. It has been assigned to VM Network.
I've got single person in an office location who needs to access a lob application at site A and a different lob application at site B via RDP.

Site A and B don't need to communicate with one another.  

What would the most efficient and cost effective way to be to accomplish this, preferably using Sonicwall equipment?

We are running an intranet in our organization...now we are thinking to provide the access of our intranet to the users even through their mobile..How can we do this... and is this possible?

Hi Here is Opengear IM4216. I could not find relative document on it. Is it layer2 or layer3 device? What kind of device is it? Thank you
An interface on a Cisco switch show Total Output drops is 776, txload 4/255. What does it indicates ? Does it tell something wrong for the cable or the device connecting to the switch ? How to improve this situation ?

My parents just bought a Smart TV. They've been having trouble navigating it. They live several states away and do not have a smart phone or tablet to Skype/FaceTime me and show what they see and what they're having trouble with.

Is it possible for me to remote access into their smart TV through WiFi to walk them through navigation?

I am super new to phone systems and am only asking in the absence of my usual go-to phone engineer. We have a client with a FreePBX phone system and Cisco SPA525G handsets. They would like to use the Link Key 5 button (bottom button to the right of the screen) on their reception phone to pickup any internal or external calls for when other staff are away from their desk.
I've tried a few things in the config of the phone, but have not been able to get this working yet.
I don't think we should need to adjust the config in FreePBX (could be wrong), as apparently this used to be working and the PBX config hasn't changed in quite some time.

This is as far as I've been able to get with the research and reading I've done (which doesn't work):
fnc=blf+cp;nme=Call Pickup

Any assistance would be appreciated!

Does anyone know of any good temp sensors so I can monitor my server room and phone closet, that I can check the temp on my Iphone using an app.  Also, I would need the device to send me alerts if the temp reaches a certain temp.  It would be nice to be POE.
I would like it hard wired, as I tried a wireless one, but it's giving me issues.
How does Cisco licenses and support work?  I want to buy a 3850 PoE switch here in US (Amazon?), configure it here, and ship it over to Canada.  
Does it affect support or licenses at all because it will be in diff country?  

Also can someone explain the quote for me?  Besides the hardware price I have these:
- CISCO Cisco One Foundation Perpetual - Catalyst 3850 48-port
- CISCO SNTC-24X7X4 C1 Cat 3850 48 Port Full PoE
- CISCO SWSS UPGRADES C1 Foundation Perp Cat3850 48Prt

These three things are doubling the price of the hardware.  Which one of these SmartNet and what's the other stuff?  Do I need it?

Sorry too many questions.  VAR being vague on that.  Thanks in advance!
I have only one standard copper pair phone line. I very frequently use this line to play recordings of voice and music from my computer to the phone line using a Plantronics MX10 interface device. I also legally record some phone calls. These capabilities are ones that I MUST have. Lately I am having SUBSTANTIAL difficulty dealing with the "Phone Company" and employees that have little knowledge and even less desire to solve problems. I am sick of spending so much time trying to reach someone that can and will solve the problem. Yesterday I was on the phone for slightly over three hours! I got nowhere.
I know very little about voip or magic jacks and such. Is there another solution for me that will allow me to continue to leave my computer hooked up to a copper pair so that I can continue to use the phone system the way I utilize it presently? My isp suggested that I purchase a MagicJack PLUS but also was candid with me that he was not completely sure it would accomplish my goals.

(ASIDE) For those members that are perhaps wondering what is at the heart of this problem I will say that I treat people as I would like to be treated....honestly. I am being overcharged for normal phone service and refuse to be cheated every month for something I am not receiving. Getting rid of the entire companies service 100% would end my problems with Century _ink for good.
I have been trying to work with Sonicwall support on this issue and have made no progress.  We have been using the appliance in the past with split tunnel enabled but, due to security requirements, we can no longer allow split tunnel.  If we turn it off,  remote users can access internal resources we have configured, but cannot access anything on the Internet. It seems that we need to create a resource which is "anything" on the Internet but we don't know how to do that. We don't see any kind of wild card options.  We have not given our users access to "Any" resource.  We need to specifically define the resource they have access to.  We need an "Internet" resource and then we can give them access to that.  Is this possible.  Or, is there some other way to approach this?

Sonicwall support had us upgrade the firmware to 11.40-468 with the 708 hotfixes but that did not create an options for resolving this requirement.
Hi Guys,

Last week I tried to upgrade our edge 3750X switch (two switches in a stack), from c3750e-universalk9-mz.152-2.E.bin to c3750e-universalk9-mz.152-4.E5.bin.

Previously I copied the new IOS to both flash: and flash2: from TFTP, ran command 'boot system switch all flash:c3750e-universalk9-mz.152-4.E5.bin, and then 'wr mem'.

Later I consoled into the master switch and reloaded. The master switch booted into the new image successfully, but the member switch got stuck in a booting loop. The new IOS was loading, and went nearly to the end, and the master switch could see the member at some point. Then the process started all over again, and it was endless!

I tried powering the member switch off, and then on again - still the same. Tried removing stacking cables, and restarting - still no joy. Then booted the member into SWITCH: prompt, and then into the previous IOS - still a loop! I didn't know what else I could try, so at the end I powered the offending switch off and left it as it was (as the master switch was providing all the services).

Please could you advise how to resolve this issue? Any advice would be appreciated.


Building/space already have multiple ISP provisioned.  Fibre and wireless.
Before building a network what information we need to know from ISP before designing and building things out?  Just making sure not missing anything.
I am inheriting an existing space with already provisioned ISP service.
Thanks in advance.
I have just taken over 15 Meru AP200 access point and a Extreme Summit x150-24p switch. The switch have just died. I installed a new Dell managed switch but can not get into the AP 200 to setup static IP Address for all 15 AP. Anyone help with this problem, I have never worked with these products before as you problem can tell. Thank you.

I have a server with a asus sabertooth mobo that is giving me a raid critical error. Its saying at boot:

Problemis detected with array: 01 02
Critical status
A disk member of an array has failed or is not responding.

I understand what this is saying but when I go into the raid utility I cant find a way to get it to tell me which drive is failing. Also, it does show in the drive assignment the disk on port 01 is "single disk".

Asus has been no help.

Anyone knows the requirements for the racks clearance in the server room?  Or recommended clearance off the walls.

I read front should be 36" and rear 24"  Now, what about the sides of the racks?  Contractor is about to install one of my racks with its side flashed to the wall.  I believe it would be uncomfortable to mount equipment with one side right next to the wall.  Screw rails in, cable mgmt, power, etc.
What are the requirements or suggestions.  Thanks in advance.

Hello -
 There are various CAT6a cables out there.  With cabling contractors tho, if you don't specify the type they will go with the cheapest basic one - U/UTP type.  This is completely non-shielded at all.
There are a lot more: S/FTP, F/UTP, SF/UTP, and U/UTP?

What would be a recommended type for the new office run?  Thanks in advance.
