How to increase Bandwith using Cisco Radios.

We currently have Aironet 1310's that link two buildings together. We recently bought two Aironet 1142's with the hope to use them to increase bandwith between buildings.
We realize a Controller is needed too, to implement the 1142's which we haven't bought yet... and the 1142's are more for indoor than out.
First, can the 1142's be used to link the buildings together if we aim them via windows, or put them in a weather proof enclosure? Everywhere we looked we didn't see any 802.11n devices for outside...
Second: or is it better to buy more 1310's...and somehow multilink them together adding bandwidth?
The goal here is to increase bandwidth, of course.
Thanks,

First, I think this question was better in the wireless subsection rathen than switching :-)
The 1250 is a better choice than 1140, because it has external antennas and that's what you want for a bridge. 1140 doesnt' support bridge setup.
Moreover both 1250 and 1140 can work as standalone. Check on cisco.com, you will see IOS software for both those APs.
1250 is indeed a good way of increasing bandwitdh. If you go the 1310 way you can only have 3 of them (using all 3 available channels : 1,6,11) and I discourage building them in eterchannel as people are tempted to.
Hope this helps,
Nicolas

  • How to increase built-in cisco vpn peer response timer?

    Hi,
    I use OS x in-built cisco vpn client to connect to work VPN.
    The VPN server, or perhaps the radius server, takes a long time to return a response. OS X always try for 10 seconds, then drop the conneciton when no response from the remote peer. When I use cisco vpn client on a windows machine, the vpn client has a setting to allow for 90 seconds remote peer response time. It works fine using cisco vpn client.
    I prefer to use os x as my primary working environment, so I need to fix this problme. My question is how to increase the phase 1 & 2 timer for vpn under 10.6.7. I have tried to change racoon.conf phase 1 & phase 2 timer, but it made no difference. OS X only try for 10 seconds.
    Any ideas? (besides asking work people to fix the server or radius problem)
    Thanks

    i have the same problem ... certificate is imported in keychain, but cant select it when setup vpn connection

  • XI 3.0 - How to increase performance using TibCo JMS Adapter...

    Hi,
    Does anyone have any idea if/which properties can be modified to improve the polling interval of the JMS adapter for Tibco?
    Another forum message mentioned a method called setPollingInterval, but this only seems to relate to MQ series.
    I have tried options like creating multiple communiction channels pointing to the same non-exclusive queue, increasing the server node count (this improves pickup, but reduces overall throughput as the SLD data is no longer buffered).
    I have also tried the method called "setConnAttemptDelay" on the com.tibco.tibjms.TibjmsQueueConnectionFactory class but this did no seem to help.
    Any suggestions please?
    thanks
    Brian

    The answer is to either add additional J2EE server nodes to your PI/XI instance or add additional Business Services and configure addition Comms channels for these

  • How to load configuration using Cisco USB port???

    on USB-flush configuration there. I try to download it gives this:
    Switch#copy usbflash0: 3560-ST
    Source filename [3560-st]?
    Destination filename [3560-ST]?
    %Error opening usbflash0:3560-st (File not found)
    What is the Problem? flash formatted on most Cisco (it has decreased in numbers from 16 GB to 2.75 GB)???

    Syntax is the one as Chandu poined out.
    However, i see there is a space between usb0: and the filename.
    "Switch#copy usbflash0: 3560-ST"
    Make sure there is no space in the syntax above and also the file name is correct.

  • How do I use Cisco Registered Email Service with 10.7?

    I received a email via someone using Cisco Registered Email/Envelope Service.  The authentication process required the latest version of JAVA for 10.7, which I downloaded and installed.  When I try to logon, the screen hangs with the message "Loading Envelope Tools."  If I press "open" again it states "Inactive tools."  The alternate method is to open the mail via a secure Web site, which I can open, but I am unable to download attachments.  To download attachments, I am directed to a page that begins with "x-msg:" and I get a message that says: "Safari can't open the address .. . because MAC OX doesn't recognize Internet Addresses starting with "x-msg:"

    Thanks for the info Roger, this is indeed did work for me (at least the part about signing in on apple.com, haven't tried the rest). Since Apple does not allow for the merging of Apple IDs, my plan is to use the old me.com address (from the free trial) with iCloud but then forward all the messages from the old me.com to my current Apple ID. Problem is all my devices are already associated with iCloud. So... if I want to activate iCloud using the old me.com, how do I do it?
    I have two ideas: 1) as you suggest, signing out and signing back in through the iCloud preference pane (either on Mac OS or iOS); but I'm worried this will have consequence - will I be able to sign back in to my main Apple ID account after doing this?
    2) create a new user on my Mac and then sign in to iCloud with the old me.com address there, then delete the account.
    Thanks for any help with this.

    Edited by: bg57295 on Mar 24, 2010 6:45 PM

    Hi Bharath,
    Believe me, you have an incompatibility between different build#.
    PAPI has an instance cache. When certain process has more instances than the maximum specified, the cache is switch to status OPEN. That means, that PAPI will not be able to resolve some instance queries using the information in the cache. When that occurs, PAPI forward all those queries to the engine.
    The incompatibility introduced is in the communication between PAPI and Engine. So, you only get the exception when you have more instances than the maximum cache size.

    Now What i do give me suggessin
    Thanks In Advance

    Hi,
    you don't have to stop your database to increase the file size - it's an online operation. If you are more familiar with SQL code here is what you have to do:
    use <SID> /*Put your database name here, e.g. PRD*/
    go
    select file_id, name, physical_name, size
    from sys.database_files
    where type_desc = 'ROWS'
    In the resultset you will find a column called 'name' - that are the logical file names that we need for the increase. If you have a standard installation the names should look like <SID>DATA{1-4}. Next step ist the actual increase of the files:
    /*Replace <SID> with your DB name*/
    alter database <SID> modify file(name='<SID>DATA1', size=25GB) /*25GB ist just an example*/
    alter database <SID> modify file(name='<SID>DATA2', size=25GB)
    alter database <SID> modify file(name='<SID>DATA2', size=25GB)
    alter database <SID> modify file(name='<SID>DATA4', size=25GB)
    Thats it. If you run the first statement again, you will see that the filesize has been increased. You can also check on  filesystem level.
