Sf 300

Dear's friend
        I have struck in my some network configuration.  I have two sf300 switches and cisco 827 router.  Actually sf300 does not support dhcp server.  I took cisco 827 as dhcp server and i create 4 dhcp pools in it.
How i can configure in sf300 to take dhcp service from cisco router 827.  Isit possible to configure 827 with bvi interface, when i was try i got below error.  Can anyone help me to configure bvi interface and i will link that bvi to vlan on sf300.
error in 827 router
Router(config-subif)#bridge-group 1
Bridging on a LAN  subinterface requires that the interface be already
configured for Inter Switch Link (ISL) encapsulation or 802.1Q encapsulation
sf300 Configuration:
Int vlan 1
ip address 192.168.1.1 255.255.255.0
int vlan 2
ip address 192.168.2.1 255.255.255.0
int vlan 3
ip address 192.168.3.1 255.255.255.0
int vlan 4
ip address 192.168.4.1 255.255.255.0
How i can connect two sf300 switch for redundancy ?  I connected giga4 SW1 and giga4 SW2 and mode trunk isit good or any other way i need to connect it.?
thanks in advance.

Tom still i have same problem.

  • LaserJet Pro 300 M351A Wireless Accessory?

    On the HP website it clearly states that my printer (HP LaserJet Pro 300 color M351) DOES have a "wireless capability" ...
    This statement is to be found under the "Technical Details" section in the paragraph entitled "Connectivity and Communications":
    Wireless capability - Optional, enabled with purchase of a hardware accessory
     I've Googled high and low and I cannot find out:
    What is meant by "a hardware accessory"
     Is it a print server device? Is it a wireless usb adapter? What?
     I have an urgent need to add this device to a small wirless network, but I can't figure oyt how to?
    Please help - anyone?

    Hi,
    Wireless optionality is available with the HP Jetdirect ew2500 802.11b/g Wireless Print Server (J8021A), that can be found listed within the Supplies and Accessories section below:

  • ID5.5 image dpi cut from 300 to 150 in save as ps, acrobat to pdf

    When I submitted book interior to printer, they said some images were 150 dpi. I checked the ID file links, and they showed them as 300 dpi. My process to pdf was: from ID, save as postscript file, then use Acrobat Pro with the PDFx1a2001 profile to create the pdf. Any thoughts on where in this process the images would be downgraded to 150 dpi? Here is the file as ID shows it:
    Thanks for any suggestions.

    Not really.

  • Todos os mais de 300 dolares de aplicativos comprados anteriormente na App Store, sumiram quando tive que redefinir minha senha, tive que formatar o computador e nao tenho backup, o que fazer?

    A cerca de 1 ano adquiri um Iphone 4 e um Ipad 1, durante cerca de 8 meses comprei mais de 300 dolares de aplicativos na Apple Store.
    Ocorre que vendi este Iphone e o Ipad em questao, mas mesmo aswsim tive o cuidado de desinstalar os aplicativos para poder reinstala-los em outro equipamento caso fosse necessário.
    Neste intervalo de tempo, ocorreu um problema no meu computador pessoal e tive que formatar a maquina perdendo o backup feito por meio do Itunes, recentemente comprei um Iphone 4S desbloqueado de fabrica e fui obrigado a redefinir minha senha na Apple Store uma vez que sequer lembrava dela.
    Ao entrar no site pelo Itunes, minha surpresa foi que todos os aplicativos comprados anteriormente não constavam na sessão (minhas compras) estando apenas os adquiridos a partir de entao.
    Como devo fazer para não perder mais de 300 dolares gastos em apolicativos lá?? Como reaver os aplicativos comprados?

    Por favor, perceber que este é um usuário fórum de usuários. Estamos todos os usuários de produtos da Apple como você. Se você teve dificuldade com a Apple os serviços de tecnologia, então você precisa falar com alguém mais acima na cadeia como umrepresentante do cliente. Ter todos os seus fatos, mas ser breve.

  • How do I take 300 dpi photos with my iPhone 4s? And how do I export them to my MacBook Pro at 300 dpi to use as I want to print photos.

    How do I take 300 dpi photos with my iPhone 4s?
    And how do I export them to my MacBook Pro at 300 dpi to use as I want to print photos.
    I have been using the standard camera on the iPhone and require 300 dpi to create photo books as the photos are resized according the layout.
    Your time and assistance in appreciated.
    Thanks

    Thanks Tonefox!
    After looking at a few of the links I found a mathematical equation that assisted me.
    Inches = Pixels/DPI
    eg: 3 inches = 300 pixels/100 DPI
    Using this equation and the fact that iPhone 4s takes photos that are 3264 x 2448 I was able to work out the largest print I could make with 300 DPI.
    Width 3264 pix/ 300 DPI = 10.88 inches
    Height 2448 pix/ 300 DPI = 8.16 inches
    Therefore, the largest print (with 300DPI) I can make of these photos is 10.88 inches x 8.16 inches.
    Which is great!
    So is it critical for me to change the dpi in say photoshop or does it not matter as long as I don't go above the 10.88 inches x 8.16 inches?
    From what I can gather the smaller I resize the photo the higher the DPI and the bigger I stretch the photo the lower the DPI?
    Further clarification will be much appreciated. Thanks

  • HT4910 i save my photos to camera roll. then back up but can't see it on icloud. why? we just lost 300 photos on my other iphone because we do not get proper help. that's why i need to learn now.

    You can't view your back up files at icloud.com.
    You can't view your camera roll and you can't view your Photo Stream files at icloud.com.
    The icloud back up plan allows you to "restore" your iOS device from the files you backed up at icloud.com.

  • Getting a hp mce remote for touchsmart 300-1125

    I want to add a remote control to my HP Touchsmart 300-1125 and am thinking to order the 5070-5600 HP remote (random link: http://cgi.ebay.com/HP-COMPAQ-5070-5600-Media-Center-Remote-Control-/330414657906#ht_805wt_911).
    I wonder about two things:
    1) The IR Receiver *is* built-in, isn't it? (Device Manager lists a functional eHome IR device)
    If in doubt, where should I look for the IR receiver sensor on the case?
    2) I think the 5070-5600 remote lists as being made for the older IQ series of Touchsmarts. Will it work with the newer 300 series?
    Thanks

    All MCE remotes from the past 8 years send out the same codes. There are a few newer HP specific codes, but 95% of the buttons are exactly the same, grab a 5 year old Gateway MCE remote, it'll work just the same as a new HP one!

  • Envy 120 cartridges. HP 300 or HP 60?

    Dear Support,
    Few months ago I bought a new HP Envy 120 All-in-one-printer and I'm happy with it. Now the print cartridges are quite out so I'm preparing to buy a replacement.
    I really don't know what is the correct code. That is: if I go to printer webpage, Tools, Product Information, Print Gauge, I see that the part number for cartridges is HP 300. Then I click the link "Order supply" (..Sureidentifier will identify the printer for you), but the supply is not identified (the search engine of suresupply doesn't even recognize "HP 300"). If I search for "Envy 120", the suggested replacement is HP 60. 
    Which is correct? HP 300 or HP 60?
    What about region limitations? I bought the printer from Amazon, I don't know where it really comes from.
    Thanks in advance.
    This question was solved.
    View Solution.

    Hi Mario,
    If the printer provided with the 60 ink cartridges, it is only intended to accept those cartridges for America.
    The 300 ink cartridges are intended for the same printer but for Europe.
    If you moved to another country in Europe you should contact the local HP Support in order to reset yoru pritner to acept those cartridges.
    Please let me know what region you are from so it will be possible to provide you the local contact details for a such.
    Regards and happy new year

  • I had 800 songs on my iPhone. My iPhone dumped all my songs and when I tried to re-sync my music it told me I was only authorized 300 of the 800 songs.

    I had 800+ songs on my iphone when tonight my iphone decided to dump all of my music. I tried to sync all of my music back onto my iphone and it told me I was only authorized 300 of my songs. All of the songs came from the same macbook in the first place, why the **** won't they all sync now? There's been no change or variation except my iphone dumping songs. How the **** am I not authorized? I paid for all of them! I'm seriously getting tired of apple's overpriced junk. It never works right that and nothing but screws up and screws us as consumers.

    I was doing dishes and listening to music on my phone. I tried to change the song and all the music was gone. Then when I plugged it into my macbook to resync it all it told me I'm not authorized all of the songs. It would only sync 300 of the 800 on my itunes that are on my macbook. And it's been the same macbook and same itunes account all along. Never changed. That's why I'm confused. I paid for all this music and now I just don't have it anymore cause they say so... Also, this isn't the first time my iphone has dumped all my music, it's happened twice before, but let me sync all my music back onto it the other two times.

  • Dont work driver on Scanner ScanJet 300 on winows 7

    Please, create new drivers for Scanner ScanJet 300 on Windows 7 platform. I have this divace. Dont work it on Windows 7. Windows 7 and drivers of ScanJet 300 scanner are not complianted.

    Hi @Per-Morten 
    I suspect your question would be better answered in the HP Enterprise Business Community, as your HP Printer is a commercial model.
    My technical expertise is with consumer products and software, I am sure the commercial folks would be happy to help if you re-post your question for them to answer. The HP Enterprise Business Community is an HP Forum designed for the Commercial and Enterprise customers to help one another. I am sure you will find some HP folks there to help too.
    Click here to view the Printing and Digital Imaging. When the page opens you will see the option to 'Log in' or 'Register Now' on the right. The commercial forums are separate from the consumer boards, thus you will need to register if you don't already have a commercial account.
    You may find the HP Scanjet 5400c Scanner Drivers page helpful while you wait for somebody in the commercial Forum to respond to your inquiry.
    Best of luck.

  • My ipod wont let me put more then around 300 songs on it.

    I had dropped my iPod with a case on, and picked it up and it was fine. It still runs fine and all, but when I try to put songs on it from my iTunes, it only puts on around 300 and then iTunes freezes and wont let me put anymore on. I have tried with a couple computers, so its not iTunes thats the problem. Anyone know how to fix this?

    It could be an indication that the hard drive was damaged during the fall.  I would recommend doing a disk diagnostic on the iPod's HD using the instructions given by turingtest2 in this older thread.  He also covers what the resulting numbers indicate. From there we can try to determine if the iPod has any life left or if it's time to bite the bullet.

  • G3/300 B&W Dual Display issues

    I'm attempting to hook a second monitor to my machine. The primary monitor is an Apple Studio Display 17" CRT. I'd like to hook a second VGA monitor up. I put in a second ATI Rage card, and haven't yet gotten it to work. Here's the info from system profiler on the card I've put in:

    Phirefenix,
    Welcome to the discussions. First question: are you sure it is a Mac compatible video card? If not, the second comment will not work.
    During startup, after the studio display lights up but before the software starts to load, hit the reset button on the front of the computer. This will give what I call a 'warm boot' and eliminate some esoteric issues. If that works, buy a new PRAM battery. If that does not work, verify question one.

  • When I try to connect my iPhone to my laptop to import photos and videos it says there are no files or folders under "Apple Iphone". My laptop recognises my phone and my camera roll has around 300 photos and videos but none of them come up on my laptop?

    The memory on my Phone is really bad so i cant store much. The pictures i am trying to import are really important and i cant lose them. My phone has been playing up a lot and im afraid of losing the pictures so tried to import them onto my laptop. Its a windows 8 and every time i connect my iphone a window automatically opens titled "Apple iphone" but underneath it says "no files or folders". How can i resolve this?
    Also the apple store have told me not updating may be causing problems but i cant update due to no space. i have 3 apps, around 300 photos/videos and no music. it is 16gb so i dont know why im having this problem

    This is how you import photos/videos:

    Is that what you're doing?

  • Macbook Air running extremely slow - kernel_task at 300% cpu usage

    I purchased my Macbook Air roughly 15 months ago and it's performance has constantly been impressive since I purchased it - until roughly a fortnight ago. I came home from work one afternoon and it was running at a snails pace. I had recently upgraded to Yosemite though I'm unsure if this had anything to do with it. I had also recently installed FitBit software to sync to my new FitBit flex.
    It has continued to run in this manner constantly since the problem began. It is ridiculously slow, every single request takes a very long time to respond. Logging in takes forever. When I click on an app to open it, the icon bounces for 30 seconds or more, and it's not a smooth bounce either, it's quite a jagged bounce!
    I'm hoping someone is able to provide some advice, guidance or help. The laptop is no longer covered by the 12 month Manufacturer Warranty, and I did not purchase an Apple Care plan as no Apple product I've owned before has experienced issues like this.
    This whole experience is killing me! I'm suspecting hardware failure and I'm just so sad that this could happen to the laptop I've loved so much since I bought it!
    The problem:
    The kernel_task process is constantly running at 300% or higher cpu usage, with Activity Monitor indicating the processor is being maxed out by a system task. Also, the laptop's fan is constantly running at full capacity - from the moment the laptop turns on, or wakes up.
    What I think the problem might be:
    As a result of many, many Google searches, it appears that this behaviour may be due to the Macbook Air thinking it is overheating - and I will clarify here that it certainly is not. It is cool to touch, always, when this problem occurs. (yet the fan is almost taking off!). As a result of the MacBook Air thinking it's overheating, it not only is running the fan at a very high RPM (confirmed with iStat), but it also is intentionally choking the system with 'simple requests' in attempt to cool the computer down. Apparently this is a built-in feature of OS X. The kernel has priority over user tasks, causing all user tasks to be granted a lower priority, causing the computer to run INCREDIBLY SLOW. Even as I'm typing this, I'm about two sentences ahead of what is showing on the screen!
    Steps I have taken:
    - Read widely across the internet with every possible relevant search term I can think of
    - Downloaded iStat to see if any of the temperatures are too high (they all seemed fine..)
    - Disabled Bluetooth and Wifi. (no change)
    - Reset SMC (multiple times.., no change)
    - Reset PRAM (multiple times.., no change)
    - Drained the battery completely (2 or 3 times, no change)
    - Install Windows 7 on BootCamp in attempt to bypass the issue (CPU usage was 100% constantly in Windows also)
    - Uninstalled FitBit software (no change..)
    - Uninstalled other software I did not need (no change..)
    - Attempt to boot into Safe Mode / Recovery Mode (even in this modes, the same thing is happening)
    - Repaired Disk Permissions
    - Backed up all personal data
    - Used the built-in Internet Recovery mode to format my Macintosh HD and re-install a fresh copy of OS X (Mountain Lion). (no change…)
    - Re-upgrade to Yosemite (no change..)
    I've downloaded EtreCheck and here is the output:
    Problem description:
    OS X is running incredibly slow. kernel_task process is constantly using 300% and upward CPU usage.
    EtreCheck version: 2.1.5 (108)

    Hi,
    I have an update so I thought I would share in case any other users are experiencing a similar problem.
    I made an appointment with the Genius Bar at the Apple Store.
    I went in and they ran a thorough diagnostic check on my Macbook Air and determined that the sensors were indeed faulty - several were providing no information "No reading" instead of providing a temperature. Thus, the Air was unaware of the temperature across multiple components.
    Despite the laptop being outside the 12 Month Manufacturer Warranty, the Apple Store determined that it was covered under warranty through Australian Consumer Law - the laptop is now in for a complete repair under warranty at no cost to myself.
    I couldn't be happier.
