Bandwidth Rate Issue (Aironet 1310)

We have been experiencing major issues recently with the connectivity of 2 Aironet 1310 bridges that are about 300 yard apart. They have been up and operational for nearly a year and within the last week they cannot negotiate a stable rate (1-54Mb). We have opened up numerous TAC cases in which we have validated the optimal settings. The only thing we have been able to reproduce is when we have the bridges associated and just connected direcly to our pc's on each end we can associate at stable rate of 54Mb. As soon as we plug them into our LAN switches it tanks and will bounce from 6Mb to 1 Mb. We have checked the speed duplex settings on the bridges and switches and left them at auto. I don't understand why if the rate has already been negotiated and stable that it is affected as soon as you put any significant amount of traffic accross it. The only piece of info I have noticed is the throttle counter will increment on the dot1q radio int. I have found no good information on to what the throttle counter indicates and if this having an effect on the rate. Any ideas would be greatly appreciated. Orginally the bridges were on 12.3 code and having issues, we were told to upgrade to 12.4 with no change.

Can you post the log for the root bridge both with direct pc's attached and then showing when you connect them back to the switches?

  • I need Bandwidth, Filtering & Accounting work with Aironet 1310

    Hi Mates,
    Please I need an affordable Cisco hardware or software (for SMB) to control about 200 clients in my wlan (hotsopt internet caffe)
    all work with two Aironet 1310 .
    I'm not concerned about security in the first palce, but Bandwidth, Filtering & Accounting.
    MY Regards
    Saher

    Just to be clear: You want to give wireless access to 200 clients over two APs *?at the same time?*
    That would be a Very Bad Thing, and almost certainly not possible.
    Generally speaking, with "normal" traffic (no such animal exists), you can expect to run 20 - 30 clients tops per AP.
    It is not likely that you can impose your restrictions at the AP level. More likely, you'd want to do it at the switch, possibly at the router.
    The problem is that the AP acts as a hub: shared bandwidth, and collision avoidence. Basically it boils down to every client getting a timeslot to communicate. When you have too many clients on a single AP, the clients are not talked to often enough, and you get association drops. Before association drops, you get really poor performance that progresses to request timeouts.
    The other issue is the uncontrolled mix of clients that you're likely to see. If one client is using 802.11b (11 meg), the net effect is an additional drop in available bandwidth.
    The bottom line is that it's not a plan that's likely to succeed.
    You may want to investigate 802.11a (5GHz). It has more non-overlapping channels (802.11g has three). To get that many poeple in a confined space and maintain acceptable connections and performance, the extra bandwidth will help a lot.
    Good Luck

  • Upgrading IOS on Aironet 1310

    I want to upgrade the IOS on a couple of our Aironet 1310s but do it wirelessly. The bridges I am upgrading are not accessible at the time I wish to carry out the work which is why I am not doing it via a wired connection. It isnt an ideal situation but an alternative requires an outage during working hours.
    A recently purchased 1310 had a sticker on it saying the radio interface is disabled by default in newer IOS images. Does this mean that when I upgrade the software it will automatically disable the radio interface when I reload? If that is the case I will have no alternative but to organise an outage.

    hope this URL will be of help.

  • Aironet 1310, power injector and poe cable

    Hello,
    Can the power injector delivered with aironet 1310 be supplied by a PoE RJ45 cable rather than the traditionnel DC adapter?
    The problem is, i thought Aironet 1310 was PoE. Which means it can be power supplied by a rj45 cable.
    But, when i openned my brand new 1310 box, i realized that 1st, it needs that Power Injector to work and that 2nd, Power injector needs a power supply...
    Usually when i buy a PoE access point, I just plug in my PoE rj45 cable and its power supplied :)
    Anyway, i hope there's an issue for this because where the 1310 should be placed, there's only a PoE rj45 cable arriving.
    Thanks in advance,
    lachapelle

    Hi lachapelle,
    Sadly the 1310 cannot be powered by PoE ,but, the Power Injector can be up to 100 meters away from the unit.
    Dual coaxial cable to run from the power injector to the 1300. See attached notes:

  • Lost The Cisco Aironet 1310 Web Interface????

    I've been having connection issues with my (2) Aironet 1310, which are setup in a bridge p2p mode.  A few weeks ago we had a power outage due to a lighting storm.  Well, it knocked out my non-root bridge (not connecting to the root).  So I brought it back to check the configurations, but when I try to use the web console all I get is the following page:
    When I click the "Web Console" link it takes me to the following page:
    Is there a way to get the original web console page back?

    here is the command..
    archive download-sw / force-reload /overwrite tftp:///
    Example..
    archive download-sw / force-reload /overwrite tftp:///c1310-k9w7-tar.124-21a.JA1.TAR
    to get the .TAR, go to the folder where the image is saved and then Tools >> folder options >> view >> check >> show hidden files and folders.
    Now click on the image and then copy the image name and then paste the same on the CLI... then this come as IMAGE.TAR that is.. c1310-k9w7-tar.124-21a.JA1.TAR instead of c1310-k9w7-tar.124-21a.JA1
    it should be c1310-k9w7-tar.124-21a.JA1.TAR
    lemme know how this works out for you!! if you face any difficulties while upgrading please open up a TAC case.. we wil solve this in less than 5 minutes... and the network wil be back up!!

  • AIRONET 1310 BRIDGE CONFIGURATION

    Hi I desperately need help. I am trying to configure 2 Aironet 1310s as Root bridge and non-Root bridge. When I configure the root bridge the wireless interface remains up.When I try to configure the non-root bridge the AP/Bridge will assume the role of non-root bridge and immediately disable the wireless interface with line potocol down .I tried swapping the roles and still get the same proble. I am running IOS version 12.4(10b)JA

    Hi
    I finally made a breakthrough. The issue here is the internal antannae. It seems it does not work well. I tried to use the antannae from the linksys wireless router and enabled them, I one time got the radios associate. I connected to the network and was able to ping the Pcs on each end of the network.
    Now what I am interested in finding out is why those radios cannot work with the internal antannae. The model I have is AIR-BR-1310-E-K9-R.Is this designed to come with an internal antanna. I was able to pick one bar from my laptop from within 5 metres from the bridge. so what is the issue with these radios.

  • Configuration of a Point to MultiPoint link with Cisco Aironet 1310 bridges

    Hi All,
    The previous problem of which I started another conversation here:
    http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=General&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddba023
    somehow dissapeared. It could have been a problem of interferences.
    I have another issue with other (multipoint) wireless WAN link, which I hope has a solution.
    On the central node, we have an Cisco Aironet 1310 bridge configured as root-bridge. It has a panel of four vertical polarity 17 dBi panel 90? antennas, with more than enough gain (there is a 250 mWatts 802.11 b/g amplifier, before the 4-way splitter) and excellent line of sight to three remote bridges.
    The three (03) remote bridges are also Aironet 1310 models, confidured as non-root-bridges.
    The problem we have is that it seems that when the three remote links operate concurrently the amount of lost packets is huge. When I shutdown the radio interfaces of two bridges, the remaining bridge makes an excellent link with the central node.
    It seems that some hours are more critical than others, also the links operate much worse when there is some (small) network traffic in them.
    I have read the 1310 manuals, and I can't find a sample configuration for point to multi-point links.
    Does someone knows what radio interface configuration should I need to use to establish better quality communication?
    I mean, perhaps the 1 x root - 3 x no root configuration is not recommendable for the multipoint link configuration.
    Any hints will be welcome.
    Best Regards,
    Igor Sotelo.

    Hi All,
    Thank you for the information. I configured the distance on the root bridges, but the links showed instability.
    I'm using a bi-directional amplifier. It has two pieces. According to the manuals, one is installed indoors, the other outdoors. I'm not sure if the indoors piece has the transmition module or it's only the injector.
    We could establish connection at 7 km (around 4 milles) distance from the central point, using 24 dBi antennas on the other side.
    However, we have issues with a near located point that is only 1.2 Km (around 0.8 milles) away and has a 13 dBi integrated patch antenna. The signal strenght value we get there is in the -62 to -68 dBm range, and is noticiably (5-10 dBm) lower than the strenght we get at other points of the link. And I have trouble establishing a high quality link with that point, using OFDM modulation. I tend to think that if I remove the amplifier I'm not going to reach that point at all. The EIRP on the central iste is 34 dBm / 2.5 watts, without amplifier it would be 26 dBm / 0.4 watts.
    On the opposite sites the EIRP is 33 dBm / 2 watts using CCK or 28 dBm / 0.63 watts using OFDM.
    When one looks at the central site from that point, an Motorola Canopy with passive reflector (EIRP 48 dBm or around 64 watts) can be seen. It doesn't have the same direction, but the opposite site must be large distance and could interfere with my wireless network. Attached is an amplified photo of the view. It's safe to assume that the Canopy operates in the 2.4 GHz frequency range.
    Once I connect the point at 1.2 Km, the multipoint link loses its quality, and soon the lost packets get too frequent.
    The CCK seems to be much more interfered than OFDM, I guess because of that canopies.
    Another thing I'm wondering about is if the Aironet 1310 can continuosly switch CCK-OFDM over the same point - multipoint link, without losing packets.
    What other parameters should I tweak? Is there a way to avoid interferences fromt the canopy?
    I would like to apply 100 mWatts local power using the radio with OFDM, but it seems that's not possible.
    Best Regards,
    Igor Sotelo.

  • Cisco Aironet 1410 Multipoint with Aironet 1310's

    Hello,
    We are currently expanding our wireless deployment that consists of two Aironet 1310's bridged together. We would like to hit an area in the opposite direction that is not too far away. Would replacing the 1310 in the root point with a 1410 as the root to provided point to multipoint be a feasible solution? This would make the 1410 the root bridging to two 1310's at opposite ends.
    Thank you,
    Rick

    Hi,
    Its not possible to MIX 1410 and 1310 together.. Since 1410 comes with A radio and 1310 comes with G radio and both are not compatible with each other!!
    lemme know if this answered your question..

  • CISCO aironet 1310 integrated antenna poor range

    Hi
    I am in Canada
    I am trying to configure an AIRONET 1310 with INTEGRATED antenna
    to work as an access point for clients on a campground
    The range I get is awfull (50 feet and I loose the signal completly)
    the aironet is outside and no tree are blocking it.
    I configured it all by default exept :
    -- in network interfaces : Radio0-802.11G Setting
    -- I changed DATA RATES from Default to Best Range

    Hi,
    1300 Integrated antenna model comes with a Vertically polarized 13dBi gain antenna. The beam width is 36° E-plane by 38° H-plane.
    Following is the range -
    Americas
    • 865 feet (260 meters) at 54 Mbps
    • 3465 feet (1055 meters) at 11 Mbps
    ETSI
    • 150 feet (45 meters) at 54 Mbps
    • 775 feet (235 meters) at 11 Mbps
    TELEC
    • 485 feet (145 meters) at 54 Mbps
    • 1095 feet (330 meters) at 11 Mbps
    So the range what you are getting is way too low.
    Please check the orientation of the AP, the antenna is Vertically Polarized.
    So the AP should be mounted vertically.
    Second make a note at the beamwidth 36° E-plane by 38° H-plane. Make sure that all your clients are only in this coverage area. If its an open area and you want coverage for client overall the area probably I won't go with this AP being a sector antenna not providing coverage in all 360° H-Plane.

  • Aironet 1310s Output Power Levels

    I am using a SPIRENT SR5500 Channel Emulator to simulate a channel for 2 Aironet 1310s.  I have the APs set to 1mW output which should be ~0dBm
    yet the triggered setting for the power meter within the SPIRENT SR5500 is showing ~-20dBm at the output of the 1310s.  The cable between is only 5 feet.

    I am sorry!  We have been struggling with this issue for weeks and just had one of the professors come in and play around with the cabling (as they do sometimes).  Turns out one of our 'connector types' was faulty and once all 4 were replaced the power meter of the SR5500 Spirent was showing only cable loss at -1.5dBm and not the -20dBm that had been showing at the power meter input.  Thank you so much for your quick reponse, it is good to know people care!!!  Problem appears to be solved!

  • Aironet 1310 APs dropping connections

    Hello,  I have two Aironet 1310s outdoors - one on a boat and the other on a  building. I have one ANT24120 antennas attached to each AP. I am trying  to determine why I am having dropped connections. Any help would be  appreciated.

    1) I do not know if anything has changed (at least not with each AP  or antenna). I am guessing there is more RF noise. I ran a product  called wi-spy and channelizer. There was a lot of competition, so I  hard-coded a channel that was consistently lower in noise.
    2. I have reset both bridges.
    3. I will not have physical access to both bridges till Monday.
    4. I am trying to get up to about 5 miles. I am having intermmitent issues while docked as well.

  • Aironet 1310 - not able to establish UDP vpn

    We hv installed aironet 1310 in AP as well as root and non root bridge combination with IOS 12.4(3g)JA1.
    config works fine for the normal operation like getting client connected to ap, getting IP from DHCP server on the network. The problem is with the UDP vpn. We hv an application which after getting DHCP ip establish the UDP vpn connection which always fails. Aironet 1310 is connected cisco switches.
    At some of the AP/bridge playing with the cisco switch setting (speed and duplex) it do work. But that is only a try and error method. But with few other root bridge even trying the same combination doens't work.
    Has anyone experience such issue ? Is there any config changes to be made for such UDP vpn ?
    Early help would be appreciated.

    Something in the path is tampering the packet. Probably a nat router.

  • Exchange Rate Issue ( Ditect & Indirect Quotation )

    Dear,
    Alll Experts.
    I am stuck up at one level , that is Exchange Rate issue.
    User is creating shopping cart in SRM, Local Currency is USD and the goods is ordering from Canada ( CAD ).
    While doing this amount is getting calculated   in - ( Negative ), And it is going to wrong approval for shopping cart approval.
    When I see the TCURR table I am seeing there as negative sign in exchange rate because it is maintained in Indirect Quotation.
    I want to calculate the same amount in postive figure.
    How this can be achieve? If I maintain the same in direct quotation it will calculate positive but final amount will be bigger which is not proper one.
    Experts guidance will be helpful.
    Regards,
    Sharvari Joshi.

    Hi,
    I gave the OB08 entries, not sure if you wanted me to explain the logic. Here it is..
    Maintain 'Indirect quotation' from Local currency(USD) to Transaction currency(CAD) and 'Direct quotation' from Transaction currency(CAD) to Local currency(USD).
    Direct quotation is where the cost of one unit of foreign currency is given in units of local currency, whereas indirect quotation is where the cost of one unit of local currency is given in units of foreign currency.
    Your local currency is USD:
    - Direct exchange rate: 1CAD = 0.92819 USD
    - Indirect exchange rate: 1USD = 1.08238 CAD
    The following settings have been made in the standard system:
      - Direct quotation: ' '
    -   Indirect quotation: ' / '
    Direct exchange rates do not have a prefix.
    Your local currency is USD. You enter a business transaction in the transaction currency CAD. Until now, you had to use direct quotation to enter the exchange rate (1CAD =0.92819 USD). If you have defined '/' as the prefix for indirect quotation, you can also enter the exchange rate with indirect quotation (1 USD = 1.08238 CAD) by entering '/1.08238' in the exchange rate field.
    Direct or indirect quotation can be maintained as the standard form of quotation for a certain currency pair. You use:
             - '1' for direct quotation
             - '2' for indirect quotation
    If a standard form of quotation has not been specified for a currency pair, the system automatically uses direct quotation.
    You make the settings in the IMG: General Settings -- Currencies -- Set Standard for Direct/Indirect Quotation per Currency Pair.
    Thanks

  • Aironet 1310

    hi everybody i am santosh , i have a cisco aironet 1310 running 12.4(10b)JA1 and c1310-k9w7-mx.124-10b.JA1/c1310-k9w7-mx.124-10b.JA , it was working fine but suddenly i found that it has gone to AP mode while all these days it was working in Bridgemode . could any one tell me how to revert it back to bridge mode .

    You are correct.  The power injector is just that and the bridge unit actually has all the intelligence in it.    The power injector is just your interface connection to the unit for console and ethernet and provides power to the bridge.
