Aironet 350 Bridge associations

Hi,
I have 2 aironet 350 bridges that keep disassociating and then reassociating constantly. Is there any way to stop this form happening?

Parent is "Root Bridge", end station is "Non-root bridge w/out clients." Thanks for pointing me to the Express setup page--that's the one I had in mind, but I haven't been there since day one. Now I need to figure out why, with those settings, it's allowing client connections...
The only MAC address filtering I see is (per documentation) "allow or disallow the forwarding of unicast or multicast packets either sent from or addressed to specific MAC addresses." When I look at the actual Address Filters page, it only allows me to specify "Dest Address." Not much help if I don't want to allow other connections *to* the bridge...
When I'm not in Express Setup, and go to the Setup page, I have the option at the bottom of the page (Network Ports | Bridge Radio or Network Ports | Root Radio) to go to an Advanced page. While there, I see a field called "Radio Cell role." The Root Radio Advanced page shows the Radio Cell role as "Access Point / Root." The other options would be "Client/Non-root" and "Repeater/non-root." The Bridge Radio Advanced page shows the role as "client/non-root." I am *assuming* that the Root radio here, although called an "access point" is not an access point for clients (i.e., its role is that of the access point for the far end(s) of the bridge).
I can't find anyplace to stop broadcasting the SSID...
Thanks for the help!

  • Aironet 350 Bridge

    Can you configure Bridge to work in a full duplex mode?

    ... or gang 2 or 3 350s together and load balance.
    each one will still be half-duplex, but the potential for 2 or 3 to be tied up transmitting without receiving at the same time will be reduced.
    Plus the aggregate pipe is 22 or 33Mbps nominal.

  • Monitoring Aironet 350 Bridge Link Signal Strength

    Hello,
    Does anyone have ideas/examples on using SNMP to query 350 series bridges to obtain running data on signal strength & quality? I would like to use something like MRTG to monitor signal strength, along with link usage.
    Looking through the MIB files (especially ftp://ftp.cisco.com/pub/mibs/v2/AWCVX-MIB.my)
    it looks like awcDot11TpFdbLatestRxSignalStrength is what I'm after, however I cannot see how to properly reference this. When I walk the tree from 1.3.6.1.4.1.522.3.12 it doesn't seem to list the relevant values.
    Any help/advice most appreciated!

  • Aironet 350 Failure...Twice

    A couple of months ago, I installed three Aironet 350 Bridges, each connected to directional antenna via LMR400 cable. The directionals are pointed towards an access point at the front of the campus. After abou 36-48 hours of use, the ethernet ports on the bridges locks up, and actually dies in two of the instances. I figured that it was a bad group of bridges, so we replaced them with three more, only to have two of the replacements do the exact same thing. When the port crashes, the red light comes on and stays on, even after you remove the rj45 connector. Afterwards, you are unable to access the bridge via a browser, so there is little means of troubleshooting available. I haven't had a lot of luck with the reseller, and this customer has been down since March!!
    Any help would be greatly appreciated

    Aside from on-site consulting (possibly on a contingency basis), I can only suggest that you pull it all into a lab, check all the configs, upgrade all the firmware and confirm that it's reliable before putting it back in.

  • Aironet 350 Wireless Bridge Problem

    I have inherited a wireless link between two building that used a pair of Aironet 350 wireless bridges.  I say used because one took a lightning strike and is fried.  I need to see the configuration on the remaining bridge to set up the new bridge but no one knows the user name or password to access the remaining functioning 350.  How do I reset this old buzzard?  I have tried all the instructions I have found on this site and others.  There is no reset button.  I found this out by disassembling another Aironet 350 we had which has also taken a strike.  I cannot set up the new 1300 without knowing the config of what it will be talking to.  I have been able to connect to the 350 with a serial cable and I can see some of the information.  But the only thing I get is the ip address for fe0.  I have attached the file I captured to this post.  Any help will be appreciated.  Thanks.

    If you know the IP of the 350, put a laptop on the same subnet and use a crossover cable to web to its GUI.  VxWorks CLI sucks!
    If you can get hold of a pair of 1231 APs, they can be configured to run in bridge mode and use the same antennas as the 350s.  Benefits are IOS and G radios. 

  • Need help on Aironet 1300 bridges

    Greeting,
    We have just upgraded two Aironet 1300 bridges (from cisco 350) on two buildings about 100 yards apart. They are only running as bridges. One is set up as root bridge and another one is setup as non-root bridge. Root bridge is in the main building direct connect to Cat 4506. For some reason the root bridge has some intermittant problem connect to the network. We are running the IOS 12.3(8). We changed the cable but the problem still occured. Everytime we have to reboot the root bridge in order to get it back. but all the interfaces in the root bridge show " up / up" prior to reload. The "show tech" looks fine on the root bridge. Any suggestion? Shall I change root bridge to workgroup bridge?
    really appreciate for any helps,
    Gene

    Hi Steprodr,
    I just need to clearify that the power injector is on the non-root bridge? I think the power are fine on both bridges when the problem occured. We used cisco 350 bridges before the upgrade. So the cable and port are still remain the same. The problem is more going towards from root bridge come back to Cat 4506 because both root and non root bridges can ping each other when the problem occured.
    thanks,
    Gene

  • Aironet 350 with pismo antenna?

    Hi people. I recently bought a cisco aironet 350 pccard wireless adapter for my pbg3 500. It works, i use os x 10.3.5. The problem is it doesnt reach very far. Last week a friend of mine came with his macbook and he had full signal at places where I could not even connect.
    Doing some research I found that removing the fat sticker placed on the part of the card that remains outside the powerbook, there are 2 antennas and a jack for an external one. So I tought I could use the one built-in the display that is meant for airport cards. The problem is they can not be conected directly (the cable doesnt reach and the conectors are different anyway. To make thinks worse, the powerbook cable doesnt even have the conector, just the wire. I tried making a bridge between this cable and the cisco jack (using a 15 cm cable) but doesnt improve the signal, so I think im doing something wrong, or the pismo antenna is no better than whats built into the cisco card. Maybe someone here has some experience on using a non airport card with the airport antenna.
    Thanks in advance for your help.
    Pepo

    Thanks Brent. I have a spare ibook display that I can use for testing the antena. Problem is I dont want to burn the pccard amplifier. I dont know how the antena works, or if there is already an amplifier in the display, so if I connect the output of the card to the airport antena, I may burn the card. If I touch the antena lead it has power, as well as the pc card, so I dont think they can be connected toghether.
    Also another doubt I have is actually how the antenna works. If I check the jack with a tester, I can see that the shield and the conductor of the wire arent isolated from each other, so then how do you wire them to the card when they are bridged already?
    Sorry, hope I explain myself a bit at least, my english is not good enough I think for this kind of things.
    Thanks again.

  • Aironet 350 WAP + IP Scheme Change

    Hello,
    I have an Aironet 350 Wireless Access Point running VxWorks 11.07.  We had it working fine on our 172.23.0.X IP address schema where the Ethernet and AP Radio shared the same IP address.
    We have recently moved to a 10.121.40.X IP address schema and so I made very simple changes to the network configuration of the WAP (IP address, Subnet Mask, Default Gateway and DNS).  However, now I can't get any devices to connect to the WAP even though I know they did before with the old IP address schema.  I've even tried the WAP on DHCP and the result is the same.
    What can I do to get this WAP working again?  Is it something to do with the 10.121.40.X range?
    Thanks.

    The clients are trying to connect but in Windows don't get to the 'Acquiring network address' stage.
    After a failed connection attempt the VxWorks 'Associations' page lists the client device but the 'State' is 'UnAuth'.
    The WAP Event Log shows a lot of the following type of entries but nothing else:
    00:07:57 (Info): Deauthentication from [10.121.41.19]0012f0dc17ca, reason "Unspecified Error"

  • Aironet 350 reset to factory config over vacation.

    I have an Aironet 350 non-root bridge that was reset back to its factory default configuration over a 5 day period of inactivity (Christmas vacation). I didn't set it up, so I can't say too much about how it was configured before except that it was running 12.0 firmware.
    I have upgraded it to 12.04 and reconfigured it and it seems to be running fine.
    Any ideas on what could have caused this? Could I have had a security breach?

    That could be very likely. Are you using a default configuration for security, or have you turned user-manager on and added a management username/password. Note that someone could have potentially done this via SNMP also.

  • Aironet 350 client adapters

    I have some Aironet 350 PCI cards fitted to some Compaq P4 desktop computers running WinXP Pro. These computers are part of a Domain and log in automatically using a few registry changes. This is the problem.
    When the machines log in the Wireless adapters have not finished their authentication and have not received a new IP address, but the machine still logs in. I need to make the machine wait for the Aironet card to finish it's authentication or start the authentication process earlier. Has anyone got any ideas.
    Many thanks for your time.
    Mike

    I have tested this with APs config'd with Network-EAP and Open-Require EAP. In this scenario Max Assoc does not prevent attempted associations by non-LEAP-enabled clients, which are locally authenticated (associated but unauthenticated) and claim one of the allocated associations. This can effectively block legitimate client associations/authentications. I think that local MAC filtering is the only override, and/or disabling Open authentication (forcing LEAP). Using the ACS, you can create or map External DB Users to ACS Groups and limit their access to certain NAS (AP) entries.

  • Aironet 350 AP not sending signals to laptops !

    Hi all,
    This is the 1st time I use this service...I hope someone / Cisco can help me.
    Background
    We have Airnonet 350 AP system + PCI adapter + PCMCIA. We live in a 2 story house. The Server (Win XP) is downstairs connected to the Livebox ( France Telecom )for internet conncetion. All PC downstairs connect to this livebox and work very well. But, upstairs the portable PC receive weak signals, so internet is slow or often none at all. We installed the Aironet 350 AP upstair in a central location to receive signals from the Server which is in turn equipped with a PCI adapter to send to the 350 AP on 1st floor. It works beautifuly and efficiently for 4 years already..
    NOW
    Last week I changed the Server PC to a newer one, also running on Win XP. I transfered the PCI adapter to it, and installed the software for adapter from Cisco website (Win-Client-802.11a-b-Ins-Wizard-v1701). The Associations between the Server / PCI adpter, Airnonet 350 AP, and 2 laptops on 1st floor are excellent. But, the Laptops on 1st floor just could not have access to internet ! I have tried many different manipulations.. but no success.
    Has anyone come across this pbs ? Do we need to do something to the 350 AP ? if yes, what is it ? Is there an upgarade of s/w for the AP 350 ? Etc ...
    I'd loved to hear from you to help me to solve my pbs, otherwise my 2 daughters just do not have internet connections !
    Thank you in advance.
    Joseph
    email : [email protected]

    Tks John for your suggestion.
    However, the 2 laptops were working well already while they were connected wirelessly to the old server, except the speed was not so fast.
    Seeing the new server giving us connection pbs for upstairs, I have gone backward, and put back the PCI adapter to my old server which sends signals to the Cisco AP upstairs. Now, both laptops upstairs are receiving internet and working correctly. To improve the speed up of this old server, I have removed all unnecessary programs etc ...so the speed is better. The girsl are happy.
    The only down side is that I have got this brand new server / PC which is not doing what it is bought for ..
    Frankly, I am still at a loss why the new server does not work with the Cisco AP !
    Do you still have some other ideas ..?
    Thank you in advance.

  • Windows 98 and Aironet 350 PCI Card

    I have a complicated question and would really appreciate any input anyone has. I have a network with 12 PC's that are running Windows 98 with Novell Netware. They all have Aironet 350 PCI cards in them. We recently decided to change an older PC out and took out it's Aironet card to install in the new PC which is a Dimension 4400. I install the card and the utilities and drivers and I can get the PC associated to the AP. I then install the Novell client and I can't get authenticated onto the network. I can't even get the Novell login to pop up. I can't even get out onto the internet which I can usually do even if I am not on the network. Neither my network admin nor I were here when these were originally deployed so maybe we are missing a step. Any help would be much appreciated. I would be glad to provide any additional info!
    Thanks
    Jamie

    Thanks for the further info John. I would usually say sure and do it. I am only leary because a week ago this card was happily working in another machine. A interesting point to mention is that when I go into the access point all of my machines on the AP having their IP address in a field called IP Addr./Name and the machine I am having an issue with says unassigned. The last time we had this particular issue we had the network on 40 bit WEP encryption and then got a new card for a machine that could only run 128 bit so we changed the encryption and everything has been fine since. Once again thanks for all of your help!
