Vlan trunk over wifi

Looking for advice on a problem we have.
We have a building with the WAN link etc. There is a separate building which is connected via a point to point wireless link.
We have Cisco 2960 switches at either end of the wireless link. The switch is divided into 2 vlans one for telephony and one for data. with links in the main building going into a netgear switch.
In the separate building we can access the data vlan but not the voice. The ports connecting to the wireless link are trunked and if I create a vlan in the main building it replicates to the separate building and the ports are a member of the correct VLAN.
I tested with the switches connected directly together and was fine so presuming something related to the wireless link, any thoughts welcome!!
Many thanks

I will assume the following
1. Your data VLAN is the native VLAN on the trunk ports
With that in mind you probably have an MTU issue:
In trunk ports your native VLAN (Default VLAN 1, probably your data VLAN) will not be tagged so MTU=1500,
your voice VLAN will be tagged so MTU > 1500 and your wireless equipment can't handle >1500 MTU so it drops the packets. You can confirm this by changing the native VLAN on your trunk ports to the voice VLAN and see if it works. If that's your case then either change the MTU on your wireless equipment or use 2 wireless links in non trunk ports 1 for each VLAN.
Let me know if it works.

Lost Packets in certain customer VLANs Trunked over ME

I work for a service provider that configures CPE networks for our customers. We have one customer that we are setting up a Disaster Recovery site over Metro Ethernet. The customers servers need L2 connectivity to the data center for redundancy. The customer wants their VLANs on their 4510 mirrored on a 3750 at the DR site. A gigabit ME VLAN was setup through our ME network between the 2 sites. The 3750 and 4510 were staged at the customer site and tested before the 3750 was moved to the remote DR site and connected by ME.
The 3750 and 4510 were directly connected on a dot1q trunk between the two switches. About 18 vlans are trunked between the 2 switches, about 15 of which have L3 Vlan interfaces configured.
The issue we are having is that packets are getting dropped, on certain customer vlans, but not others. All Vlans worked properly when the 3750 was directly connected to the 4510 at the datacenter.
Our network engineers in charge of the ME noticed MAC-Flap errors on ME switches at the Data Center and the DR site. It see the Mac Address of Interface Vlan 101 and Interface Vlan 318 of the 3750 switch on both the customer access port on both ME 3400 switches (uni) and the ME trunk ports (nni). No other vlans are having issues with lost packets, or connectivity.
On ME 3400 switch uni tunnel port is vlan 459. Native vlan is 540 on 3400 and is the switch mgt vlan.
Has anyone run into this before?

I think commonsense101 means the "Customer Agreement" and the following passage in particular.
"Where and How Does Verizon Wireless Service Work?
Wireless devices use radio transmissions, so unfortunately you can't get Service if your device isn't in range of a transmission signal. And please be aware that even within your Coverage Area, many things can affect the availability and quality of your Service, including network capacity, your device, terrain, buildings, foliage and weather."

VLAN trunk over Frame Relay

I want to define a VLAN 101 within a branch office on one port of a CAT3524XL, that will in turn go to a router in that branch and be trunked back to the main office router (through a frame relay connection). Once in that main router, I want that one VLAN to specifically be directed to one of the unused ethernet interfaces and in turn to another 3500XL switch for distribution. There are already VLANs in the branch that are connected to the main office, but they all come out on the main branch router's e0/0 interface. I need to make an exception with the new VLAN 101 by forcing all VLAN 101 traffic to be on the e1/1. Please HELP!!!

Yes, my requirement is to be able to direct traffic that originated on that one VLAN to a different port on the central router, where there is a captive portal device which will manage that remote traffic. I may have used the wrong term..."trunk". I really need full visibility and control of that remote VLAN. I have other VLANS (voice, data, management) in the remote branch, and they all come back through the frame. I really need to take this particular VLAN and "point" it to the available interface in the main office. Does that sound feasible with PBR? I will read more on it.
Thanks for the info Rick. Any other ideas or help is appreciated.

VLAN trunk via MPLS

Is it possible to run a VLAN trunk (DOT1Q) from a Central site to a remote over a MPLS connection?

You can do that either by using dot1q tunnelling or port based EoMPLS. For a description of these two features, please refer to the following document:

Wireless sync option not available on Itunes 10.5. After updating my iphone to IOS 5, the "sync over wifi" option is not being displayed in itunes.

hi, I managed to update both Itunes and my ios to the latest versions (10.5 and 5 respectively). I'm unable to see the "Sync over wifi" option in itunes. Can anyone help?

Maybe that's why I got lucky? I have 10.7.2. I have to tell you howeer that I did not check any check box in settings on the Notebook to enable Wifi sync, or in iTunes on the notebook. I did have options when setting up the iPad and I selected sync with computer rather than back up to cloud. Maybe that is another difference? I feel feel fortunate that as I type this my iPad is syncing over wifi and you're all having trouble.
Just to confirm I have iTunes 10.5 MacOSX 10.7.2 and iOS5 installed on the iPad. I'm going to dive in and do the phone now too. I will report any troubles, or pay more careful attention when the iCloud settings and set up come on the screen. Maybe I did something else I don't remember.

Exchange Emails over WiFi

For the last 3 days or so, I'm not able to get my exchange emails over wifi on my mac and iPhone 5 (mail app). The home wifi is working just fine as i'm able to connect and get all the other mails from gmail and hotmail but when it comes to my exchange account, I get an error 'can't connect due to network error'.
Although, I'm able to get my exchange emails over cellular data connection both on my mac and iPhone. Please suggest.

Hi Razmee,
Thanks for the reply. I've tried that but my IT guys are a nocturnal bunch of grumps. It's not officially a work appliance, therefore not officially their problem. The fact I spend my own dollars to improve my efficiency and contactability is lost on them.
Cheers

Can someone help me with backing up my iphone over wifi then restoring it?

basically i wanted to download the new ios 8 on my iphone 5c, i did not have enough memory and was unable to get onto a laptop/pc. i went onto settings>icloud>storage&backup>back up over wifi. i enable back up over wifi so when connected to wifi it will automatically back up, anyway after enabling this i pressed back up now and it backed my iphone up. i then started to delete apps and PHOTOS to get enough space, i then was able to get onto a laptop and tried to restore my iphone but it would not let me . it said i had to download ios 8 first then it would restore my device so i tried this and it will not download the new update, i still dont have enough memory to download the update but i do not want to delete more photos if i will be un able to get them back.
basically if i delete more photos to make enough space for ios 8, and then restore my iphone will i get all of the photos, apps and games i had before i started to delete them (baring in mind i did back up my iphone over wifi)
please help getting very worried over this, thanks

IPad 3 not showing up in iTunes (Win7_64) over WiFi

I have an iPad 3 I'm trying to sync over my WLAN. It's running iOS 7.1 and connecting to iTunes 11.2.2.3 on Windows 7 64-bit. Upon launching iTunes, the device will appear in the left navigation pane after about 10 seconds, and will stay there (greyed out with a spinning progress wheel) for about 15-20 seconds before it disappears. I am never able to display the status or contents of the device over a wireless connection.
-USB connections do work and I am able to manage, browse, update and sync the device.
-I have tried connecting over USB and checking/unchecking the "Sync over WiFi" box. That has not solved the problem.
-I have tried establishing custom inbound and outbound Windows Firewall rules to allow all traffic to all programs and ports from the iPad's internal IP (10.10.10.18 on a /8 network), but that hasn't fixed the problem.
-AppleMobileDeviceHelper.exe, AppleMobileDeviceService.exe, iCloudServices.exe, iPodService.exe, iTunesHelper.exe, iTunes.exe and mDNSResponder.exe are all running at the time of attempted (and failed) sync.
-Wireless syncing worked properly while on iOS 5. Really regretting updating to iOS 7 right now. Lesson learned, unlikely to ever update again.
I've tried a number of solutions but as I cannot recall 100% of what I've already tried, I am willing to start at square one to get this resolved. For what it's worth, I'm a 14-year IT professional so you can talk to me about pinging, firewall rules, subnets (iPad and PC running iTunes are on the same subnet), protocols and ports and I will know what you're talking about. Hope that helps speed things along.
Any assistance you can render would be most appreciated.

Wireless Sync
To set up Wi-Fi syncing, connect your iOS device to your computer with the included USB cable.
Click the Device button in the upper-right corner. (If viewing the iTunes Store, click the Library button first.)
If you don't see your device, choose View > Hide Sidebar.
In the Summary tab, select "Sync with this [device] over Wi-Fi."
When the computer and the iOS device are on the same network, the iOS device will appear in iTunes, and you can sync it.
The iOS device will sync automatically when the following conditions are true:
The iOS device is charging.
iTunes is open on the computer.
The iOS device and the computer are on the same Wi-Fi network.
While the iOS device is in the left-hand column of iTunes, you can select the content tabs and configure sync options.
Click Apply or Sync to sync the iOS device.

320N Freezes when trying to transfer data over wifi

I have the 320N and I am very frusterated. I would just take it back, but I bought it brand new on Amazon.com, meaning I will have to pay shipping because I threw out the box and the return shipping form for RMA's! I don't even know if Amazon will take it back without that paperwork, but anyway here's the issue...
I don't have any N cards yet, but I upgraded to this router because my home internet service is faster than what my older WRT-54g could route. This new router does route and I can now achieve the rated speeds of my ISP (50/10 mbps).
I can transfer large files 6+ GB WIRED between any of the LAN ports on this device. However if I try to transfer much data over wifi, the router will simply stop working. The lights on the front work fine, they blink like there is activity, and the power LED is solid, but it won't pass traffic and the wifi SSID dissapears. I run a constant ping to the router (ping -t 192.168.1.1) and I get <1ms replies. On my laptop I initiate a download of a 1GB file which is shared in my windows 7 homegroup. Within a minute or two the constant ping to the router starts timing out. Internet access to anything (wired or wireless) instantly ceases. New introduced devices will not grab a DHCP address. Existing PC's whom already have their DHCP address can talk to each other only if wired. The wireless transmitter stops broadcasting the network and devices no longer see it on the airwaves. The only way to fix it is to power cycle it.
It doesn't even have to be a large file over wifi to transfer. Just now as I'm typing this post I noticed the constant ping on my other monitor started timing out. I power cycled the router in time for me to submit this post. In fact I had to do it three times in the time it took me to write this post. This is the most frustrating experience I've had with any wifi ap/router, and I play with Cisco gear at work that run real IOS.
Here's what I tried so far.
Reset factory defaults by holding in the rear reset button for over 30 seconds.
I can confirm this resets the defaults as the password and all other settings are back to default.
I tried WPA2 Personal. I tried WPA. Router still freezes.
I tried it with just the default settings. Router still freezes.
I've reset the router numerous times. Still freezes.
Power cycle it for more than a minute. Still freezes.
Reflash it with Linksys's latest firmware. Still freezes.
What do I do next? I have a feeling it's the same problem as in a lot of the HP Printer firmware boards. That problem is poor solder joints on the BGA processor connection. To fix that you put the formatter board in an oven at 400 degrees for 5 to 8 minutes. After that time you just let it cool to room temperature. The oven heats the poor solder joints enough so that it reseats and gets a better connection. There are hundreds of posts of success on this. I also hear that the solder connection problem exists for many of the older revision Xbox 360 game consoles causing the infamous "Red Ring of Death".
So do I try to fight with Amazon to take this back and eat the shipping?
Do I void my warranty, open the device up and put the board in the oven?
Do I buy another router from a closer store, but then put this one in the box and take it back?
Do I just cut my losses?
Do I just use this as a wired router (disable Wifi) and hook up my WRT-54g and make that act as just an access point?
Thanks for the advice.

Ok I've had my replacement 320N for almost 1 full week now, and while at first it was fine, come Sunday it appears to freeze during heavy transfers. I was streaming an HD movie to the laptop connected to the TV. 3/4ths of the way through the movie it started skipping. What do you know, the whole network was down. No internet or anything. Power cycle the router and everything was back up. Needless to say, I finished the movie through the wired connection. The next day I tried copying 8GB of data wirelessly. The SSID vanished 1/3rd of the way in during the transfer.
What is wrong with this stuff? Linksys doesn't make things like they used to. This 320N is so cheaply made I don't think I could recommend it to anyone. I might see if I can send this back to Amazon and get a Netgear.

I am trying to download iOS 5.1 on my iPhone and iPad. Both times it tries connecting to the software update server and just hangs there. I've tried doing both over wifi and get error message. What do I do?

I cannot download the ios 5.1. I'v tried doing it through itunes after downloading the latest itunes. It says that my phone and ipad both have new updates and tries to coonect to update software server. That is where it hangs up and just keeps trying to connect but never does. Then when I try to update my devices over wifi, it tries and thens gives me a download failed message after a few minutes. What do I do?

This has solved loads of people who have this issue and have used an alternate DNS setting. Below are instructions for both iPhone OTA and on you Mac
If you are getting the error message "Unable to check for update" when you try an OTA (over the air update)
Change DNS Servers
Settings -> Wi-Fi
Click the blue arrow on your connected network
Delete everything in DNS and replace it with 208.67.222.222, 208.67.220.220
Try again
If this works, you will probably want to remove the WiFi network using "Forget This Network" and then reconnect to it to get your original DNS servers back. Alternatively, make a note of the original DNS servers before deleting them and replace it after you are done.
If you are getting the error message "Unable to check for update" when you try through iTunes
On your Mac
Choose Apple menu > System Preferences, and then click Network.
Select the network connection service you want to use (such as Wi-Fi or Ethernet, unless you named it something else) from the list, and then click Advanced.
Click DNS, and then click Add at the bottom of the DNS Servers list. Enter the IPv4 address for the DNS server.
You can use OpenDNS
208.67.222.222
208.67.220.220
or
You can Google Public DNS if you want
8.8.8.8
8.8.4.4
I have actually repointed my routers DNS so all my devices now point to OpenDNS servers

Does BIS over wifi depend on type of BIS Plan???

Hi all
few days back i bought my first BB ( Curve 8520) & activated BSNL (India) BIS LITE Plan (unlimited e-mail access only, no browser, no social networks etc. ) which is perfect for my needs.
My problem is i can't get BIS data services over wifi - white dash indication instead of green check in front of wifi connection option, no e-mail over wifi, only browsing is possible. As my office is basement where GSM Signal aren't available, I am badly in need of BIS over Wifi.
I tried very thing given in the various forms from device wipe, wifi diagnostics, bb ip pinging, telneting, HRT WIFI 60 registration to hard reset etc. many times & also did talked to Customer Care a lot but couldn't get my problem solved.
After all communications BSNL Customer Care finally told me that I can access BIS Services Over Wifi only if I take BIS Unlimited Plan (which is 3 times costlier than my current one & quite unnecessary for my needs) & with my current Plan I can't access BIS over wifi.
This makes no sense, basically I don't believe this, never read or heard anywhere. BB document mentioned below regarding accessing blackberry data services through wifi doesn't mention any caveat like this!!!!!
h t t p ://uk.blackberry.com/ataglance/networks/Accessing_BlackBerry_Data_Services_Via_Wi-Fi.pdf

Hi and Welcome to the Forums!
The carriers indeed each do control the services that they provide under different data plans. Further, at the bottom of page 6 of the document you cited, it states:
Check with your wireless service provider for supported services and features. Not all Blackberry data plans support Wi-Fi access to BlackBerry data services.
Hence, it sounds like your carrier does not provide, under the plan you have, access to the BIS infrastructure via WiFi.
Best!

Yes, if you are provisioned by your carrier to do so. IF both phones are iphones with IOS 5.0 or higher then you can use imessage.

Definitely sounds like an issue with your Wi-Fi network. Do any other devices on the network have similar issues? Is it an issue only with downloading apps? You can check by trying to load a website in Safari.
I would try turning your Wi-Fi router off for 1 minute, and back on again.
After doing that, disconnect and re-join the Wi-Fi network on your iPhone and try downloading an app again.

Is there any way to move a file or something from one computer to another that will let the new computer backup my iphone over wifi? I don't want to have to sync my phone to the new computer (my sons computer).

Hi,
I have my iphone 3GS setup to be able to backup and sync with my computer over wifi. But I want to be able to backup to my sons computer also.
The things is I don't want to have to sync to his computer first to do this. Is there a file or something I can move from my computer that is setup to his that would let his see my iphone over wifi?

If you don't have access to the old computer any longer, '''no'''. Unless you were using something like the Google Toolbar & Google Bookmarks or Xmarks, which would have your bookmarks in an online account that you could access. Firefox doesn't include an online storage feature for personal data, yet. That is coming in a future version.
If you have a friend at your old job maybe they have access to that old PC and they could export your bookmarks to a file and email that file to you.

You say you have iOS 7 beta. If you are a developer you have access to the private OS 7 developer's forum
