CUWN & Apple Bonjour

Hi All,
I'm a seasoned user of Cisco networking products...however this is now in jeopardy...... as I'm driving myself crazy with a problem which is has become resident after upgrading to a CUWN soultion. The basis of my problem is Apple OSX clients ( MacBooks / iPads / iPhones )  cannot connect to any resources via Bonjour. I have done lot of research and I'm not the only one, however some individuals have managed to resolve their issues by 'messing' with their multicast settings...i havnt had any joy at all.....this is now imapcting production networks
In use I have a Cisco 2106 WLC & 1142N APs. Below is a show network summary
any help / guidance would be much appreciated

  • Facing issue while trying to disable automatic discovery of devices through Apple Bonjour

    Hi All,
    I am facing issue while trying to disable automatic discovery of devices through Apple Bonjour.
    Background: Whenever our application is in running state, devices are automatically discovered if it connects to PC. We are using Apple Bonjour's auto discovery technology( mdnsresponder ).
    We are registering a particular service type by using DNS API "DNSServiceRegister". Service type is getting registered properly and we are able to discovered that particular type of device.
    Platform:  Windows 7.0 / MAC 10.8
    Issue:
    But we are facing issue while trying to disable auto discovery of a device programmatically. i.e, unregistered a service reference programmatically from our windows application.
    To unregistered a service we are using "DNSServiceRefDeallocate" DNS API. But looks like it is not working properly.
    Is this DNS API “DNSServiceRefDeallocate” is correct one to unregistered the service?
    Here is the step by step procedure that we are following to de-allocate a service reference:
    1.Browsing / Query a service by using service type to get service reference (DNSServiceRef). 
    2.Get reference socket FD by using DNS API "DNSServiceRefSockFD".  
    3.Select a socket by using "select" API.
    4.Close the socket that we got from step 2 by closesocket().
    5.Delete the service reference by using DNS API "DNSServiceRefDeallocate" and service reference from step 1.
    Are we missing any step to unregistered a service?

    Original problem I noticed was that regular websites I go to (such as msn) were only partially downloading.  I could see the text on the site but no pictures or videos.  All web surfing was extremely slow.  When I would go to a site such as man I would see another address in the lower left corner for "ads1.msads.net" or "cdn.optimizely.com" that is was trying to connect to. I tried using all three of my browsers (firefox, safari, chrome) and got the same response on all browsers.  After I spent some time researching the issue I decided I probably had a adware/malware problem so I decided to try adwaremedic.com.  I could also not access that site along with thesafemac.com or apple.com.  I was also getting the same response on my other devices (iPhone, iPad, and a mac air).  I could not access any of these sites on any of my devices although I could get to almost any other site although it was very slow.  At that point I decided to unplug the router.  I also did a number of other things before then to try and manually get rid of any adware.  Eventually I got msn back working, apple.com, and the speed was much faster.  But, I still can not access adwaremedic and thesafemac.com.  I could access these on my phone with 3G but not on my wifi.  This is where the problem still stands.  I am sure I still have some adware on my computer and need to find a way to remove it.  I am no techie so the complicated manual fixes are difficult for me to do.

  • WAP561 - Apple Bonjour trouble

    Hello,
    I have two access point WAP561 with the last firmware ( 1.0.4.4). I have big trouble with apple Imac & Macbook.
    -Apple disconnecting
    -Bonjour Discover didn't work after 2 days
    I must reboot every 2 days the AP for workaround the problem.
    I had try new settings :
    -disable Green ethernet mode
    -Fix Multicast rate
    -Fix channel
    -Disable Bonjour
    The bonjour discover still not working after 2 days ...
    Thanks for your help

    What do you mean with bonjour discover exactly? airplay?
    We have Bonjour enabled on all access points and airplay devices show up fine (though sometimes it can take a bit).
    Try upgrading to the latest firmware 1.1.0.4 and re-enable bonjour on the access point and leave Green ethernet disabled.

  • Problems networking win7 pc to Mac with printer attached using apple bonjour

    Bonjour print wizard says “no bonjour printers are available”
    Have Mac networked to 2 PC’s. One has win XP, the other win 7 home prem (hereafter referred to as pc2).The printer is attached to the Mac. I can print from the Mac and the XP pc -but not from the win 7 pc (pc 2). Bonjour is installed on both the pc’s.  Whenever i open the bonjour print wizard on pc 2, it says “no bonjour printers are available”
    THINGS I HAVE CHECKED OR DONE TO RESOLVE THE ISSUE:
     system pref. > printers& scanners - verified that the Mac is set up for sharing.     (see screen shots 1-3 )
    2) Verified that the network is intact and functioning normally - i can xfer files from one to the other.
    3) On pc 2 - opened devices & printers - it shows my printer as the default printer
    4) Attempted to delet and reinstall the printer - when trying to reinstall the printer, got
          error msg “windows could not connect to the printer”
    5) checked firewall issue - under “allowed programs and features, there was a tic in the
      bonjour service and a tic in the box for home/work  network . I understand there is a 
       UDP 5353 that needs to be open but i did not know how to access this port to verify
    that it was open
    My observations are that pc 2 cannot “see” the printer installed on the other side of the mac.  The Mac can see it as does the xp pc.  I’m thinking its a firewall issue but don’t know how to go any further.  Any and all help appreciated.

  • Cisco WLC with Bonjor services - MSE 3310 compatibility

    Hi All,
    We have a Cisco WLC 5508 currently running on code 7.2. We have Cisco MSE 3310 appliance (which is EoS & EoS) and it is running on code 7.2 as well.
    Now, we want to implement Bonjor Gateway services to support Apple Services such as Apple TV, Apple Printer etc.
    My understanding is that in order to deploy Bonjour gateway the controller needs to be at least on version 7.4.
    I can upgrade the Controller Code, but I need to know the compatibility between Cisco WLC code 7.4 (7.4.100.0) with Cisco MSE 3310 code (7.3.101.0, as it the highest code available). MSE 3310 appliance compatibility with WLC Code 7.4 ?
    I checked the Cisco Software Compatibility Matrix, and it's not clear at all.
    http://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html#pgfId-148309
    Thanks and Regards,
    CJ

    If you really want to keep everything compatible, you might want to look at another route, like using Avahi as an mDNS gateway.  Take a look at this document... there are other mDNS gateways out there which can work, but this doc is strictly for the Avahi:

  • WLC - AP Groups - Multicast - Bonjour - Apple TVv3

    Good Morning
    first off - Should start off by saying I have followed the Apple Bonjour deployment guide [except for interface group] portion
    I have searched high and low, here and there to no avail.
    http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_tech_note09186a0080bb1d7c.shtml
    I am aware that the bonjour gateway IOS may or may not come out in Oct/Nov 2012, which maybe my only option at this point.
    Is this not working because of my AP groups setup or have I misssed something
    I can only get bonjour to work if multicast - unicast mode is selected, but our network slowly grinds to a halt, so it is not an option
    when I first connect to the wireless I see 1 bonjour device for about 3 minutes and then disappears.
    I can not see the appletv at all with an ipad, airplay does not appear at all.
    We have the following setup.
    2 campuses - Campus 2 is simular setup, but WLCs higher model and ios 7.2 and clients and subnets are double
    Campus 1
    2 WLC 4404 ios 7.0.230.0
    30 AP groups mapped to 30 Interfaces using subnets with /23 bit subnetmasks

    controller 1 239.239.5.1 and
    controller 2 239.239.5.2
    multicast is enabled
    IGMPsnooping as well
    On Switch multicast routing is enabled
    all AP group subnets and Mgmt vlans are PIM enabled dense mode
    set up a trunk to ubuntu server to act as a bonjour gateway, installed avahi and vlan

  • Apple TV does not work with 877W

    Hi all,
    I am using an 877W as my DSL router and trying to use Apple TV or other Apple Bonjour services over Wireless. It is simply not working although I tried several IGMP configurations. I've seen some references to 877W issues but they were all about bridging between wired and wireless. In my case though everything is on wireless (PC with iTunes, Apple TV and and iPhone to be more specific). I wanted to ask once more as I've also seen references to people having this setup working ok.

    I tried with igmp snooping on and off with no luck, also it didn't helped to add 239.0.0.0 as a static group to the interface.
    If you have apple stuff working on your 8xxW environment I appreciate if you can share your configuration, any other ideas are more than welcome.
    Many thanks,
    Cagri

    Hi Cagri,
    Hope you've found an answer to your problem already, if not I had similar issues trying to get mine to work.
    I did manage to get it to work in the end, I've added an article to my blog which goes over what I had to do to get it working.
    Basically, configured correct multicast-routing groups, IGMP v3, pim dense-mode on both the radio and BVI interfaces and it started working.

  • One solution for Apple TV losing connection to its iTunes Library

    In 2012 I bought an Apple TV3 to let me use the AirPlay features of my New iPad with my HD TV. All worked fine and still does. Later in 2012 I subscribed to Netflix and enjoyed streaming movies to my HD TV via the Apple TV. Having had such a good experience with it so far I bought another for our bedroom TV and another for a relative, hoping they would have the same great experience with it.
    Both of my Apple TV units at my house have worked flawlessly since installing them. We can start watching a Netflix movie downstairs then go upstairs and carry on where the movie left off.
    At my relative's house the experience was not so flawless and has resulted in about 2 months of frustration but happily their AppleTV3 is now also working as expected. It has been quite a journey to get to this point and had a surprising solution.
    I am the 'go-to' person in my family for these things so I installed the Apple TV for my relative.
    My relative has a Windows XP (SP3) PC running the latest iTunes (11.0.2), a BTHomeHub 2 router, connected by WiFi to the Apple TV. The PC was connected by ethernet cable to the router. I installed the Apple TV, set up the hdmi connection to the HD TV, connected it to the WiFi network, upgraded to the latest iTunes on the PC, added the Apple ID for Home Sharing to iTunes and the Apple TV and could connect to the iTunes library on the PC, all good so far. I could play video or music or podcast or view photos from the iTunes library on the PC but after a short time (a few minutes or so), if I tried to play a different video or music track the I would get the familiar spinning icon and the Apple TV would not play the media file. Often the Apple TV would still show the contents of the iTunes library but would not play anything from it. When it was in this state it was still possible to play iTunes Trailers or Purchased content or a Youtube video or display photos from my library. This proved it was still connected to the internet and to some extent my library on the PC because it could display photos.
    Initially I thought it was a WiFi problem as that was how the Apple TV was connected to the router. So as I already had a Powerline ethernet link running from the router to the TV for the Humax Freeview box for the BBC iPlayer, I ordered a small network switch to share the Powerline ethernet cable with the Apple TV. However the same drooping connection problems were apparent. I tried changing the QoS settings on the Powerline link, tried to prioritise TCP or UDP or both , but no improvement. I decided to abandon the Powerline link in case it was 'too slow', perhaps that was the issue.
    I tried one of the Apple TV units from my house, where they were working fine and I got the same problem, at my relative's house it behaved like their unit, it would connect play a movie (all the way through if we let it) but after a few minutes if trying to play something else it would not play anything further. I tried their Apple TV at my house and it worked there, so the unit was not at fault.
    At various times while troubleshooting these problems I have unistalled iTunes, reinstalled it, uninstalled Bonjour, reinstalled it (it comes with iTunes), searched the registry and cleaned it (Warning: do this at your own risk as you risk destabilising Windows), I have tried disabling my firewall on the PC and/or on the router, uninstalled the Antivirus / Firewall software (Norton) on the PC, I have added the Ports required for the Apple TV to my router and firewall software, I have read many, many forum posts about what has worked for other people and I tried them all in various combinations.
    I decided having tried the above that the problem must be the Windows PC, so I swapped it for a few days with a laptop, connected wirelessly to the router. I had an iTunes library on the laptop so I shared it with the Apple TV and stopped iTunes running on my relative's PC.  For a few days it actually worked, the Apple TV would play one movie/music track and I could select another and play it after a few minutes, a partial solution had been found except the laptop was needed elsewhere and I wanted the Windows PC to be the source for the iTunes library. I briefly considered suggesting they should buy a modern PC or Mac as their Windows PC was around 9 years old, may be that was the problem? This would have cost around £400+ and was out of the question. Fortunately I had a spare PC and I decided to swap it with the Windows PC, it was only a couple of years old and as such it must be 'better' I thought. Swapping one PC with another and transferring e-mails and documents etc. took quite a few hours but it was done. I uninstalled iTunes, reinstalled it and set up the home sharing again. This second Windows PC was running XP (SP3) and Norton 360 Firewall/Anitvirus software. I checked that after installing iTunes the Program rules in Norton were allowing the TCP and UDP communications expected by the Apple TV, I noted these were not specific ports but all TCP and all UDP communications were allowed. All of this met the recommendations that other posts had suggested. I tried it with the Apple TV but no, exactly the same problem, the iTunes library could not be found after a few minutes.
    I found that if I restarted the Apple TV it would connect and play a file (movie/music etc) but if I played an iTunes trailer or just waited a minute or so then it would lose the connection. Another symptom would be when I landed on the 'Compters' icon it would tell me to 'enable home sharing on the PC with this Apple ID' , which I had already done.
    If I tried playing via the Apple TV while selecting tracks from within iTunes on the PC, then sometimes the AirPlay icon was present or not present, sometimes worked and would then always not work until I restarted at least iTunes and the Apple TV, if not also the router or PC, whatever I tried it would not result in a connection between the Apple TV and the PC that would survive more than a few moniutes at a time.
    Having swapped the Windows PC hosting the iTunes library with another I swapped the Apple TV again with one from my house, again same behaviour. So this suggested the problem was the BTHomeHub router as that was the only bit of hardware not exchanged. I compared its settings with the same unit at my house, I tried forwarding ports, I tried chaging the security from the default 'WPA & WPA2' to WPA or WPA2, still no solution. I tried reducing the default WiFi connection protocol from 802b/g/n to 802/b/g. I tried variations of all the other possible settings that could be changed but in the end set them to match the ones at my house. Still no solution. I considered buying an Airport Extreme or similar to link that via an ethernet cable to the router and enable it to be the WiFi access point for the Apple TV. This would have cost around £80 similar to the cost of the Apple TV itself, so was also dismissed as an idea.
    I decided to restore the router to factory settings, this was done and I set up the WiFi connection again to the Apple TV, still no solution, same behaviour on the Apple TV. I decided it must be  a problem with the WiFi so I tried a direct ethernet cable trailed through the house from the router to the Apple TV to eliminate the WiFi involvement, that would have to be the answer, wouldn't it? No, same problem.
    I discovered some useful diagnostics along the way that are somewhat techie but worth persevering with as they could be useful for diagnosing what the problem could be. Find out on your router what the IP Address is for your computer that is hosting your iTunes library and the IP Address for your Apple TV. The IP address is essential for either device to connect with each other or the internet. The Apple TV IP address can be seen via Settings/General/Network, it has the form like '192.168.1.69'  and for the PC it was '192.168.1.80', the values don't have a particular significance but the last digits after the 3rd dot will be different for each device.
    On the PC (or Mac), open a Command (PC) or Terminal(Mac) prompt and try to 'ping' the Apple TV to see if you get a response
    e.g.
    c:\ping 192.168.1.69
    or
    c:\ping apple-tv
    You should get a response indicating the number of milliseconds it takes for the 'ping' to be returned to the PC from the Apple TV , this will show that the PC can connect to the Apple TV, if it does not get a response then you should check that the PC and Apple TV are connected to the same network (either wired or wifi). You must be able to get a successful ping for the connection between the PC and the Apple TV to work at all.
    Another diagnostic is to check the network status on the PC (or Mac)
    e.g.
    c:\netstat -an
    This will show all the current TCP/UDP connections and also the local and remote IP addresses and ports. Look for the IP address of the Apple TV in the third column, there will be many rows returned so just concentrate on the rows with the IP addressses of the PC and the Apple TV
    e.g.  look for rows like the following:
    TCP 192.169.1.80:3689  192.168.1.69:49123 ESTABLISHED
    UDP 192.168.1.80:5353  *.*
    UDP *.123                     *.*
    TCP Port 3689 is used by the Apple TV to communicate with iTunes for playing content. This connection is essential, there may be more than one 'established' connection to the remote Apple TV from the local PC.
    UDP Port 5353 is used by the Apple Bonjour service to send multicast communications between iTunes and any iOS devices on the same network, such as the Apple TV, again it is essential.
    Port 123 is used by Apple products to obtain the date and time, the UDP row above shows that any local IP Address can communicate with any remote IP address on the router's network and provide it with date and time information. 
    If your firewall software on the PC is blocking any of these ports then the 'netstat' command is useful to see if you need to unblock any. In my experience, this port unblocking was not necessary as when I installed iTunes, the Norton software automatically set up appropriate rules for the iTunes program, and opened the required TCP and UDP communications as iTunes needed.
    Likewise, on the router itself, I have the UPnP setting enabled and this allows software like iTunes and Bonjour to traverse the router's firewall without it being necesssary to explicitly set the ports to be forwarded.
    If I started the Apple TV, and ran the 'netstat -an' command over the next few minutes I could see the number of rows for the Apple TV diminish, and this was a symptom of the dropping connection problem.
    Ultimately having replaced the Apple TV with another 'working' one , swapped the PC, restored the router to factory defaults, disabled the Windows or Norton firewall, tried ethernet and WiFi connection between the router and Apple TV it struck me that the only component I had not  considered was the insignificant ethernet cable linking the PC to the router. This has been present since the router was installed for the original PC around 4 years ago. But surely this was how the original PC and the swapped in PC were getting to the internet quite normally and successfully? Also this was how the Apple TV was accessing the PC via WiFi then via the router through this ethernet cable, there was no way it could be the cable, cables don't allow a connection for a short time and then cause a timeout can they?. Thus, confused, and with all other avenues explored, I removed the cable between the PC and the router and enabled a WiFi connection from the PC to the router. After restarting the PC, Router and Apple TV, just to be sure, I tried the Apple TV again.
    I could play some music on the Apple TV from the iTunes library, I could play it for a minute or so and then go to movies and play a movie from the iTunes library. I tried to play an iTunes trailer, some YouTube videos, these worked as usual. I then went back to the library and yes, I could play another music track or another movie. I forced the Apple TV to 'sleep' via Settings/General/Sleep Now and tried again, I woke it up and could play any music or movie from the library. Elated, I went out for meal with the family, nervously hoping throughout the meal that the solution had been found. After a couple of hours we returned, woke up the Apple TV and yes, oh yes!, it would connect with the library and play a succession of music or videos without seeing any dropped connections. Several hours later I could wake up the Apple TV again and select any content from the iTunes library on the PC and play it, finally the unit is behaving as I would expect.
    This solution may not apply for all, but it worth following all of the components in the path between the Apple TV, router, computer (either PC or Mac) and the iTunes library and checking that each is able to commmunicate successfully and over a period of time reliably so that the Apple TV can perform as flawlessly as it is capable of. 
    Don't, as I did expect the solution to involve a complicated series of special settings of ports or communications protocol changes. Do perform a clean install of iTunes and keep it updated, do keep Firewall settings simple and let the settings be default settings, do rely on UPnP (Universal Plug and Play) on the router. Let the router select which channel it wants to use, it will select the channel with least interference...and check out that insignificant ethernet cable if you have one. It might work fine for general communications from the computer to router to the internet but it can be a source of connections dropping on the Apple TV!
    My relative is now a happy Apple TV user too.

    Useful to watch what is happening to the TCP/UDP connections when the Apple TV is connected to iTunes and when it is actually playing some media from iTunes and when it stops playing.
    To see this, use the Network Statistics command 'netstat' from a Command prompt (Windows PC) / Terminal Window (Mac):
    e.g. for Windows:
    c:\netstat -an 5
    This repeats the netstat command every 5 seconds, use Ctrl-C to quit the command. (Use 'netstat -h' for help with this command)
    While iTunes is running there will be a number of TCP records displayed for the computer's IP address using port 3689, showing at least 3 ports in use for the Apple TV's IP address.
    i.e.
    TCP host_ip:3689 apple_tv_ip:49187 ESTABLISHED
    TCP host_ip:3689 apple_tv_ip:49196 ESTABLISHED
    TCP host_ip:3689 apple_tv_ip:49255 ESTABLISHED
    When it is playing content there are more connections established, some of these rows will gradually disappear when the media file stops playing. These addional TCP records show iTunes using different ports from 3689, but only while media files are being played.
    When a video file is played, (on this Windows PC at least) the iTunes host is using ports 4463 and 4464, with the Apple TV using port 7000. When playing a music track or podcast, the iTunes host is using port 4472 or 4489 and the Apple TV is using port 5000.  
    When the media is playing, the fourth column returned by the 'netstat -an 5' command : 'State' shows as 'ESTABLISHED' and shortly after the media file is stopped playing it shows as 'TIME_WAIT' until the record disappears after a minute or so.

  • TS4123 This is not correct solution. I have fresh copy of Windows 7 64 bit and I have the same problem.  Autorun only shows the Bonjour service.  It started when try to sync more than one iphone.

    This is not correct solution. I have fresh/new copy of Windows 7 64 bit and I have the same problem. 
    Autorun only shows the Apple Bonjour service.  It started when try to sync more than one iphone over WiFi. I have two iphones and an iPad. I turned off syncing over WiFi and still has high CPU utilization. One of the CPU's is pegged at 100%.  It is the AppleMobileDeviceService.exe process.

    For the record, I then followed the suggestion of MarcDCMB in https://discussions.apple.com/thread/4291206 of just manually restarting the Apple Mobile Device service in Windows services.msc once each time after starting iTunes and the service no longer hogs CPU after that service restart.  Not too painful as a work-around, and apparently an effective one, but clearly not a solution to the problem.  Again, as above, all the other solutions didn't work for me and I have no conflicting software as far as I can tell. So you'd have to say this Apple's problem.
    Also FTR, I am still on the 5.2.0.6 version of the Apple Mobile Device Support MSI and I don't know if that is relevant to this work-around working but my sense is that it is NOT relevant.  I'll report back on this thread if I re-upgrade and the problem returns in spite of the service-restart approach.

  • WLC 5508 -7.4.100 mDNS Bonjour snooping

    Hello
    Have 7.4 installed and configured for Bonjour Snooping. All is working, but working too well. We have a large campus that house 2 schools and each school is complaining that they can see the other schools AppleTV devices.
    I have played around with a few different scenarios to see if I can localize the bonjour traffic.
    I guess I am looking to create a logical split for bonjour devices amoung the schools.
    Apple came to the school and informed us that the IPAD has a limit of 64 devices that can be seen via the bonjour. At some point we will have over 100 AppleTV added.
    so we have 3 wlc 5508's with 7.4.100
    we have 2 SSIDs that span the whole campus
    using AP groups to segment the floors in buildings
    So the schools are logically split with AP groups
    Here is what I have tried
    I created few mDNS profiles and assigned the services for Apple TV - let's call them school1 and school2
    I assign the mDNS profiles to the interfaces dedicated each school
    enable snooping on the WLAN with profile of none
    The end result is that devices from both schools can be seen.
    I tried to create new ssid for apple TVs and a new ssid for 1 schools teachers
    I followed the vlan select example
    http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_tech_note09186a0080bb1d7c.shtml
    end result is that devices from both schools can be seen
    I have tried the mDNS without multicast enabled just like the video shows to no avail - I assume maybe my AP groups might be more complicated then the example of just 2 vlans

    I have tried combinations of things, but I must be missing something
    In the webinar, Cisco said it will use filtering to restrict which  clients can see which services (Apple TV's, etc). What will Cisco use to  filter Bonjour requests?
    according to this article
    http://www.pcadvisor.co.uk/news/network-wifi/3376119/cisco-answers-user-questions-about-upcoming-apple-bonjour-gateway/#ixzz2SIDqFH49
    The filtering options are: · Per WLAN/SSID · Per VLAN or AP  Group · Per Interface Group (which is a group of VLANs pooled together).
    A Bonjour service policy can be created and applied on any one of  the above criteria. In the future, we will support per-user Bonjour  service policies which will come as a RADIUS attribute from the AAA server.

  • Wlc 5508 multicast/bonjour

    hello,
    i have a wlc 5508 with code 7.0.220, with multicast enabled in it and on the lan too.I am having a bit of confusion getting bonjour to work on the wireless side. Looking at some of the cisco docs, i still have some questions on how to get it working in my specific enviroment.
    I have the wlc conected to the lan via a port-channel.  2 wlan (ssid1 and ssid2) each wlan maps to a specific vlan (dynamic int), the management int (also used for dynamic ap-manager) on a third vlan (vlan x).
    The requirement:
    I need to get Bonjour working between ssid1 and vlan-x, so my wireless clients (in ssid1 can use bonjour with their laptops) can synch between wireless and wired. I know that you can do this within the same wlan (ssid) but in this case, when a user has a laptop wired into the network he cant comunicate to the wireless device. I read about Vlan Select and Multicast Optimization however, from what i understand i need to setup an interface group and just assign my wlan1 and management int to it, correct?
    Is there anyone that has this type of setup working? Can you provide some configs/print screens.
    Another scenario that may come into play would also be when or if i need a different segment (vlan y) in my lan to also "bonjour" with ssid1? For this i assume i would need to create a dynamic interface on the wlc using the same IP segment and do the a new interface group?
    thanks in advance

  • I have an iPad 2.  I cannot get it to print from our Hp photosmart 6525 printer.  Both Hp and apple say these machines can use AirPrint.  Can anyone help

    I have an iPad 2 and cannot get it to print from our p photosmart 6525 printer.  Does anyone know how to get the AirPrint to work between these two machines?

    Hi,
    As soon as the devices connected to your network the printer should appear as AirPrint.
    You may ensure it is connected by clicking the wireless icon on the printer screen to locate its IP, then type the IP into Safari and check if you can access the printer homepage from your iPad.
    If the printer conncted but still not being detected as AirPrint, ensure you have the latest firmware for your printer:
    http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03312867&cc=us&dlc=en&lc=en &product=5271613&tmp_track_link=ot_search
    If the printer still not being dedected I would rather suspect the network as AirPrint uses Apple Bonjour and therefore require your network to support multicasting to operate..
    You may test it by temporary setting direct connection using Wireless Direct, if the printer being detected without using the router please clarify your router brand and model to better understand your router capabiities.
    The steps to enable Wireless Direct can be found listed below:

  • Epson Stylus Photo 2200 and Bonjour

    My Epson Stylus Photo 2200 printer can use either Firewire or USB. When connected directly to my G5 with Firewire I can add printer features which include setups for "Borderless" and "Minimal Margins" printing.
    However, from my MacBook Pro, after installing the latest Epson driver, I can print only in Standard mode through Bonjour. This is with the printer attached to my Airport Extreme USB port.
    I contacted Epson and this was their reply:
    "Thank you for contacting the Epson Connection.
    You will need to contact Apple and inform them that there Bonjour protocol
    doesn't support extra features like borderless and minimal margins. As
    stated before, Epson America supports the product only with a direct USB
    connection to a USB port on the computer and a direct Firewire cable to a
    firewire port on the computer. Epson America doesn't support or test any
    type of third-party printer servers, switchs, routers or Apple base
    stations. Apple has already stressed that there base stations do not
    support the Epson Status monitor. Unfortunately, if the Apple Bonjour
    protocol only supports the "Standard" printer driver, there is nothing
    Epson can do about it and you will need to talk to Apple and see if they
    have any work around. "
    How can I get this printer to use these features that I use regularly without connecting directly from computer to printer? Is there a work around?
    It seems silly to have to connect directly. After all that's why we got MacBooks - to access the internet and print - remotely!
    MacBook Pro   Mac OS X (10.4.8)   2.33 GHz Intel Core 2 Duo 2GB SDRAM
    MacBook Pro   Mac OS X (10.4.8)  

    You can try uninstalling the drivers for your printer and re-installing the printer drivers....Also, then try to add the printer port and try to check the same.....hope that should sort this out....
