Aironet 1300 Ethernet seems down

Hi,
We've installed an Aironet 1300 (with external antenna) at the top of an 80 foot mast. Before installation we configured it with a static IP, setup its SSID etc etc. We also tested connecting to another WAP etc. All setup was done using its web interface.
However we cannot access it using the ethernet port on the power injector. If I connect using the console port I can see that it is running, however during initialization it says that it can't bring up the FastEthernet port.
If I do 'show ip interface brief' then it lists the IP address against BVI, but says the ethernet port is down. We've tried a different power injector with the same result.
Does anyone have any idea what we're doing wrong? We've had no similar problems with the other 20+ Aironet's we've installed.
Thanks
Richard Cronin

Hi Richard,
What I have observed is that if nothing is connected on the ethernet interface, while initializing it always throws this error.
As you mentioned that the you are not able to access the bridge ethernet connection is down and this seems to be the reason why you are getting this error.
Now coming to the point please crosscheck if the connection is done as -
1. Plug a Category-5 Ethernet cable into the port on the power injector labeled 10/100Base Tx to Device.
2. Plug the other end of the Ethernet cable into the Ethernet Port on the access point or bridge.
3. Plug a Category-5 Ethernet cable into the port on the power injector labeled 10/100 Base Tx to Network.
4. Plug the other end of the Ethernet cable into your 10/100 Ethernet switch, hub, or network.
5. Connect a suitable 48-VDC power source to the power receptacle labeled DC48V
I am sure that you must have done the connectivity as above but just to cross check. Just cjeck for TX to device/network
Also note that the overall span can not be more than 200mts. 100 per segment.

  • Aironet 1300 radio keeps on shutting down

    Hi,
    I have a problem with the wireless bridge connection using aironet 1300. It work fine before.no changes were done. The problem is that the radio keeps on shutting down.in the web interface radio is enabled but down. i have to manually diable it then enable it back to resolve the issue. Problem is random and this is happening on both aironet. Below is the log.
    on the first aironet:

    Verify that when the radio interface is shutdown, the workstations can connect to the server immediately. Also ping from the AP to server and workstations to verify if there is any difference seen to the results seen prior to the radio interface being shut down.

  • Gaining Internet access through an Aironet 1300

    I set up wireless networks in feedyards using the Aironet 1300 as a Work Group Bridge. Typically the bridge is setup out in the middle of the feedyard to broadcast an SSID, with an Omni Directional antenna. We mount a patch antenna on the office and have it connect to the SSID using a Buffalo Ethernet converter. My question is, if the office has internet, how can I get the internet out in the feedyard. Yes the computers on the office network do have internet and can communicate with the pc's out in the feedyard. Any help would be greatly appreciated. Thanks.

    Hi,
    if we are using 1300 WGB and we have same SSID on the "root" side i.e. your office, then users connected to this WGB should be able to access internet. Are we using same SSID on both sides for internet access? Are we using any VLAN? Is there any security setting we are using on WGB or on our root AP?

  • Help with four Aironet 1300 with mountain in the middle

    I am a novice at configuring Cisco equipment and need some pointers on what roles I would use to configure this site. The site consists of one main office, mountain top and one remote site. The main location with has a DSL connection, Server 2003 configured with DHCP, ip network 192.168.0.X and one Aironet 1300. The mountain top site has line of site to the main office and to the remote site. We have two Aironet 1300 on the mountain top site. At the remote site we have one Aironet 1300, network switch and a few pc?s. I think the Aironet at the main office needs to be the root bridge, but how should I configure the other Aironet?s? On the mountain site how would I connect the two Aironet?s together? Crossover cable? Also, I had a problem using telnet to configure the ip address on the Aironet?s at the mountain top site. I read the how to configure ip address when DHCP is disabled using HyperTerminal, but I can not get the access point to respond. At the remote site and main office I was able to configure the Aironet?s ip address to 192.168.0.180 and 192.168.0.185 and add a WEP key and a SSID. Basically the remote site needs access to the office site. Sorry for this being so long and thanks in advance. Casey

    My advice is try them as two bridge connections (root and non-root). Have you tried this: http://www.cisco.com/en/US/customer/tech/tk722/tk809/technologies_configuration_example09186a008058f53e.shtml
    About cable at the mountaintop, it depends on the distance between them.
    For the IP config, just put an address on bvi 1:
    int bvi 1
    ip address 192.168.1.1 255.255.255.0
    no shut ( maybe ?)
    exit
    ip default-gateway 192.168.0.1 (if necessary)
    That' it. Does it ping at all ? Are you trying from the ethernet connection ?

  • Building to building Bridge link using Aironet 1300's

    We have a requirement to link two adjacent buildings that are about 20-metres apart over a public road. I need some advice on what the best solution will be.
    Initial thoughts are a pair of Aironet 1300's configured as Wireless Bridges but the antenna type and where to mount them is confusing me. Will the internal patch antennas be enough for this or will we need external antennas? If so what type - directional or? Do the AP's need to be mounted externally or can we simply mount them internally facing each other through windows? What do we need to be aware of regards signal overlaps and interference etc?
    What looked like a simple setup seems to have opened a can of worms....
    Thanks
    Andy

    Hi Andy,
    The 20m distance is quite short.
    In this case, as recommended by Cisco*, for AP1300 series, you can use the AIR-ANT2410Y-R antenna. This directional antenna can be used/installed indoor or outdoor.
    Approximate Indoor Range at 6 Mbps : 548 ft (167 m)
    Approximate Indoor Range at 54 Mbps: 165 ft (50 m)
    *http://www.cisco.com/en/US/products/ps5861/products_data_sheet09186a008022198b.html
    Look under 'Table 4. Antennas for the Cisco Aironet 1300 Series Outdoor Access Point/Bridge with RP-TNC Type Connector'.
    Both AP1300 and the antenna can be installed indoor. You need to wall-mount the antenna facing each other from each building.
    Since the distance is only 20m, you can play around with the transit power to control the signal distance.
    As for overlapping channel & probability of interference, do a simple site survey (can use freeware NetStumbler) and make sure your antenna does not mounted near equipment like microwave, or any equipment that produced high frequency noise.
    Hope this helps.

  • Aironet 1300 as AP

    Hey all,
    I have recently been given the opportunity to provide a wireless network solution to a 3 adjacent condos. As condos at a beach go, they are composed of 99% concrete and glass. My ability to run cable is extremely limited as every cubic centimter of each suite is privately owned and there are no interior hallways, janitors closets, or otherwise air conditioned public access locations. My initial instinct was to utilize the Aironet 1300 given it's durable characterisics and the harshness of the potential environment (think blazing sun and hurricanes). The configuration could be with one root and many non-root access points. Does this sound reasonable? Are there caveats that I should be aware of (this is my first time with cisco hardware). Second I have been fortunate enough to acquire two 1300 series bridge/AP units for testing. I have utilized the CLI interface to reset them to what I belive is the "factory default" settings. Then I used the web GUI to make one 1300 a root and the other 1300 a non-root where both are set to use WEP and accept clients. I am concerned that I may have misconfigued something as the coverage of these Aironet 1300's barely reaches 50 feet in any direction where as my $50 Netgear router with AP reaches a good 250 feet in any given direction. Something seem wrong here. I've tried differnet channels with no appreciable improvment in performance. I've tried a generic 802.11B client card and the Cisco CB21AG-a-k9 client card. I've tried one AP (no bridge) and two AP with a bridge between the two. I still get consistently poor results. I'm not new to wireless networking, but I am completely new to Cisco products. Any ideas would be greatly apprediated.

    I have alot of experience with cisco and with cisco think inside the box and with the 1200 -1300 look at you antennas. We did a few hotels in Atlanta and every other room was made out of a speacial fire material. In short the effect was in the halls signal str was around 40-50 for 400 to 500 feet when we put the ap in the stairwell signal was only good for one room over i would say roughly 10 feet (in a different enviroment they worked great. I would say take it outside and see what result you get then look into the antenna u say you have 2 for test i assume it is the cisco test units but still you might want to look into antennas to meet you penitration needs. maybe a mix of valuepoint 15 or 18 dbi rugged antenna line and the cisco I have had great penitration with that mix, and they only run like $100. hope that helps. Pardon my spelling speed was factor here on another mission.

  • Aironet 1300

    Hi,
    Does the Aironet 1300 series works as repeater ? And does it works both as bridge and access point at the same time ?
    Thank you

    Hi Jorge,
    Operating Roles for the Autonomous Access Point/Bridge
    The autonomous access point/bridge unit can be configured into one of seven operating roles
    Root Bridge Specifies that the unit is operating as a root bridge and that it connects directly to the main Ethernet LAN network. In this mode, the unit accepts associations from other Cisco Aironet bridges and wireless client devices.
    Non-Root Bridge Specifies that the unit is operating as a non-root bridge, that it connects to a remote LAN network, and that it must associate with a Cisco Aironet root bridge using the wireless interface.
    Root Bridge with Wireless Clients Specifies that the unit is operating as a root bridge and accepts wireless client associations.
    Non-Root Bridge with Wireless Clients Specifies that the unit is operating as a non-root bridge and accepts wireless client associations.
    Access Point Specifies that the unit operates as an access point connected to the main Ethernet LAN network. In this mode, wireless client devices are allowed to associate to the unit.
    Repeater Specifies that the unit is operating as a repeater (also called repeater non-root) that is not connected to the wired LAN and supports wireless clients.
    Workgroup Bridge Specifies that the unit operates as a workgroup bridge connected to a small wired Ethernet LAN network through an Ethernet hub or switch. The workgroup bridge must associate to a Cisco Aironet access point or a Cisco Aironet bridge.

  • Aironet 1300 antenna diversity query

    good day!
    does anyone had already configured an antenna diversity for aironet 1300 with 2.4Ghz frequency?
    we want to have a ring type network, we have a site A that needs to have a stable link and this site A has an line of sight to two active sites, this are site B and site C. site B is a root bridge and has a different frequency and SSID and site C is a non root and also has a different frequency and SSID, do i need to re configure the two sites (B & C) to have a uniform transmit frequency and SSID so that we can have an antenna diversity in site A? so that, in case the link between site A and site B will have a problem the data will be re routed to the site A and site C link. Can anyone give us some tips to make the antenna diversity works.
    hoping for some replies. thanks!
    wel

    maybe you are confusing diversity with redundancy??
    If this is a point to multi-point setup and A is central to both B and C, then A should be the root bridge. B and C should be non root and have the same SSID as A. The channels are determined by the root bridge(A).
    If the link between A and B goes down, C and A will continue to work only if A still works. B will still be down. If A goes down, both B and C are dead.
    You will need to do multiple bridge shots with two root bridges as in A to B and A to C and possibly B to C with a bunch of spanning tree in there somewhere.
    You should research this further; at this point the shot itself isn't the hard part, it's getting the fail-over to work correctly.

  • Trouble with Aironet 1300 series

    I have a cisco aironet 1300 series and i need to reset it back to factory default.  the directions say push the mode button while the access point is off and then turn it on while the mode button is down...
    i don't see one button on this thing anywhere.
    help needed

    Hi Jim,
    The 1310 bridge/injector do not have a mode button for configuration reset. However, you can reset the configuration if you use the console port on the injector:
    1) Connect console port and power-cycle unit
    2) When IOS starts loading, hit ESC key twice to get to the boot-loader prompt
    3) At the boot-loader prompt show a directory of the flash filesystem (dir  flash:)
    4) Delete or rename the files "config.txt" and "env_vars", then boot the  system ("delete flash:/config.txt" "delete flash:/env_vars")
    (The default user/pass should be Cisco/Cisco)

  • Cisco Aironet 1300 Series Power

    Can the 1310ap receive it's power from a POE switch?

    Hi Edward,
    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:
    Cisco Aironet 1300 Series
    Cisco Aironet 1300 Series Access Point/Bridge Power Injector
    The Cisco Aironet 1300 Series Outdoor Access Point/Bridge Power Injector,converts the standard 10/100 BaseT Ethernet interface that is suitable for weather protected areas to a dual F-Type connector interface for coax cables that are more suitable for harsh outdoor environments. The Power Injector also provides power to the outdoor unit over the same cables with a power discover feature and surge protection. To support longer cable runs from your wireless network switch or router, the Power Injector LR is designed to accommodate up to a 100 meter coaxial cable run plus 100 meters of indoor cat5 cable?enabling total cable runs up to 200 meters.

  • Degradacion de Enlace punto a punto con Aironet 1300.

    Se tiene un Radio enlace punto a punto con Aironet 1300 con version 12.3(2)JA3, pero el enlace presenta por momentos perdidas de trafico de hasta un 40%, se ejecutaron estos comandos (AP1300_TPas#dot11 dot11Radio 0 linktest) y (show dot11 linktest), pero la salida del ultimo (show), no se entiende muy bien.
    y ademas,
    Como se puede probar la causa de la degradacion?
    Gracias.

    Also in English....
    Greetings,
    Yes, your link is terrible!
    You have very exccessive retries, this should be less than 10 % on an ideal bridge link. I always try for less than 2%.
    It would be difficult to say where these numbers should be, since I have no idea about your
    bridge link and the path it takes or the obstacles in place, etc...
    However, a generic explanation can be surmised this way: dBm values are reflected in a negative integer such as -65dBm.
    If you look at a number line with 0 in the middle (think of an outdoor thermometer), the positive numbers go to the right of the 0,
    and the negative numbers go to the left.
    The noise floor is going to be located all the way to the left. The object is to have your signal as far away as possible from the left side.
    For example, the point where the equipment stops working at 11Mbps is about -86 or somewhwere in there and it might be higher at -80,
    depending on who makes it. The signal has to be at least 25 and preferably 30 dB away from the noise floor of your particular equipment to have an
    reliable link. According to your test, your signals are at -79, -81 and -86 on most tries. This is why the radio is transmitting at 5.5Mbps and all the
    way down to 1Mbps, because it cannot sustain an 11Mbps link. The fact that it works at all in these conditions, is a testament to the quality of the equipment!
    The first thing you need to trouble shoot is the link itself. If you do not have radio line of sight, your link will act like this. Just because you can see the other side
    of the link does not mean it will work.
    You need to be able to clear the 1st Fresnel Zone by 60% or you should just forget it. Trees, small buildings, etc. can cause this interference.
    A proper path analysis should be performed by a highly qualified, (and probably expensive) engineer. This is your first step and must not be overlooked.
    This testing will determine what you can accomplish and what kind of numbers you should be getting. Once you have that, then you can ask where the numbers should be.
    I was going to suggest checking the connections for water and damage as well, which would be cheaper, but is very labor intensive and if your problem is in the link,
    it will not matter what you do to the cables and connetors.
    Good luck,
    John

  • Cisco Aironet 1300 QoS

    Hello, I have 2 Cisco Aironet 1300 Bridges which provide data and voice communication between 2 buildings. Up until recently QoS has not been needed, but lately there appears to be congestion due to reports of poor voice quality. Building A houses a V3000 NBX Telephone system, Building B houses approximately 30 remote IP phones. Building A and Building B are approximately 100 yards apart. No VLAN's.

  • About Aironet 1300 Outdoor Bridge.

    Hi,
    I have a question about Aironet 1300 series Outdoor Bridge.
    in case of 1300 series, it is supporting with 802.11g protocol. BTW, I wanna use it with 802.11a protocol on Aironet 1310 series. Is it possible ?
    If so, how to do I have to it ?
    I wait your good answer.
    Thanks.

    1310 only support 11b/g, not support 11a.
    1410 support 11a

  • Secure Wireless Site to Site Bridge - Aironet 1300 or 1252?

    Hi there,
    We're planning to connect a building no more than 50m away to our network via wireless (after careful research. The builing will only house 2 people, one requiring just internet and email access for ordering materials, the other will be doing document scanning - currently scanning files of roughly 15Mb every 3-5 minutes to an SQL server in the main building. They will also need to retrieve similarly sized files from said server within the same timescale. The solution would need to offer WPA2 security and a hidden SSID.
    I have been pointed in the direction of the Aironet 1100 which now appears to be discontinued, so the Aironet 1300 was suggested instead. Will this 54g device be sufficient for the activities above and if so, I guess I will just need to configure each unit as a bridge (1 per building?)
    I have also been looking into N type devices and found the Aironet 1252 but I believe that this is an internal device? I have the facility to locate it by a window/ very close to the outside of the building on both sites but not sure if this would be cost effective. Am I right in thinking the 1252 would require me to purchase additional antenna to go with it? If so, what type would be suitable as there are several listed on the site.
    Finally. I'd like the solution we go with to be expandable (if it allows) as another building within the same area is also being looked at and would benefit from having a similar connection to it. Whether the bridging would allow for this, or another 2 units would need to be purchased is something I am unsure of.
    I'd really appreciate some feedback from someone with experience of both units or experience in setting up a similar configuration as I am quite new to this side of wireless
    I have included a basic Visio diagram of my proposed configuration; I hope it is of some use.
    Thanks in advance.

    Hi,
    the 1310 will offer sufficient throughput. But if you add buildings, maybe you will start reaching the limit ...
    The problem with the 1250 is that it's not meant to go outdoor as it is, apart from that it's perfect for the job.
    The type of antennas strongly depend on the location of the building.
    If the 3 buildings are in a line with the main building in the center, you will need an omnidirectional antenna. The point is that your bridges should all hear each other, so their coverage zone should include all other bridges. Then it's possible to have one AP at each site, the main site AP being "root" and the other being "non-root". If too hard, you could also go with 2 APs at the central site and then you can go with directionnal antenna toward each building.
    And the 1310 can come either with an internal antenna that is very directionnal or with external antennas connector. The 1250 is always for external antennas.
    Note also that the 1250 requires a bit more power than normal PoE allows.
    I hope this helps,
    Regards,
    Nicolas

  • Security on Aironet 1300 bridges

    I am a newbie on this fourm. I required your suggestions and recommendations. I have aironet 1300 bridges. I want to connect them in point to multipoint envt.
    I want to have one root bridge and rest as non root bridges. But i want to implement authentication of non-root bridges through root bridge. Please suggest what is the latest and strongest authentication and security protocols that i can use. Please i am looking for an early response.

    EAP Authentication type provides the highest level of security for your wireless network. By using the Extensible Authentication Protocol (EAP) to interact with an EAP-compatible RADIUS server, the root access point/bridge helps another access point/bridge and the RADIUS server to perform mutual authentication and derive a dynamic unicast WEP key. The RADIUS server sends the WEP key to the root access point/bridge, which uses it for all unicast data signals that it sends to or receives from the non-root access point/bridge. The root access point/bridge also encrypts its broadcast WEP key (entered in the access point/bridge's WEP key slot 1) with the non-root access point/bridge's unicast key and sends it to the non-root access point/bridge.

Maybe you are looking for
