Cisco 1200 as bridge

Hi everyone
I am about to use Cisco 1200 series AP as bridge , but I have seen and I have compared it with Cisco 1300 and 1400 outdoor models , and I saw that 1200 is mainly for indoor (LW).
Now the question is :
1. Can I use it as outdoor bridge for Point to Point linking ?
2. What will be maximum distance with reflector grid antennas (and patch antennas)?
3. If in practice , is it stabile ?
Thank you

Again I stress I can only go by what I'd install in the UK so it may not be applicable wherever you are! Also, I always try and avoid mixing vendors equipment if at all possible so I would use either one of two Cisco antenna, I've also listed antenna cables, use the shortest you can:
AIR-ANT1949 Yagi mast mount 2MB at 29.49 km.
AIR-ANT3338 Solid Dish 2MB at 42.62 km.
AIR-CAB020LL-R 6m antenna cable 1.3db loss
AIR-CAB050LL-R 15m antenna cable 3.4db loss
AIR-CAB100ULL-R 30m antenna cable 4.4db loss
Ranges and throughputs are Cisco's, you may find the biggest problem is clear line of sight over that sort of distance.
For more information check the antenna guide here:

You can have this one free of charge : ) just don't forget to award points if it's of use : )

Cisco 1200 Access Points as Bridges - Won't work

I could use some help. I have a pair of Cisco 1200 AP's that I'm trying to use as bridges.
I have selected one as a Root Bridge, the other as Non-Root. The non-root shows the wireless interface down and the log reveals 'no association'.
I have verified NO security, identical SSID's, broadcast SSID, no encryption, no WEP, they are sitting 10 feet apart, same channels, etc. etc.
Can a 1200 access point serve as a bridge?

I went to Security > SSID Manager and selected the only SSID as the infrastructure SSID and it did nothing. If there is another place to toggle 'Infrastructure SSID' on and off other than by assigning one, I'm unaware of it.
Any other ideas?
Thanks.

The maximum cable distance from antenna and Cisco 1200 series.

Hello all!
I?m using the Cisco 1200 Access Points Series with two 2.2dBi dipole antennas. I have read the installation guide for that Access Points and that can be installed with the antennas in separated places. But this guide didn't mention the maximum distance for the antenna cable...
Somebody here can say me this maximum distance?
Had somebody here made this kind of antenna installation with cable?
Thanks.

Oh Yeah!, I absolutely agree on "shorter is way better"
Given any chance / choice at all, I'd try to keep the cable length under 25 feet. If the option is available for a NEMA cabinet to get the cable shorter, I'd probably do that too.
Since it's good practice to use a chunk of fiber optic cabling between the external stuff and the inside network, you may as well put the AP as close to the antennas as possible and convert the copper to fiber for the long haul.
You get some lightning protection (at least you won't smoke all of the systems sitting on your LAN) and better signal strength (and probably signal quality too).
For something like a 200' run, if forced to do it (we're talking "gun to the head" forced here), I'd probably be looking for something like Andrew LDF4-50 1/2" Heliax with probably a weeeeee bit O' amp tossed in for good measure.
That would also imply that the system would also have to be re-certified, because of the non-standard components ...and a pretty good budget to boot.
Sometimes you gotta do what you gotta do.

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 1200 on long distances

I need to know (if anyone have in practice). What will be maximal distance in ideal conditions with Cisco 1200 series AP for outdoor point-to-point connections in WGB mode with high gain directional antennas ?

Console into the AP and post the log. This will help understand the issue better.

Cisco 1200 empty .csv file

I have flashed the cisco 1200 ap using the upgrade utility. Everything checks out ok but the .csv file is empty.Did i miss something here?
Details
Model:AIR-AP1232AG-S-K9
Autonomous IOS:12.3(7)JA2
Lightweight IOS:
c1200-rcvk9w8-tar.123-11JX1

The MIC is a Machine Installed Certificate. The AP has the certificate already installed, there is no need to
generate a self-signed certificate. That is why the .csv file is empty. You will not have to put any certificate information on WLC/WCS for this AP.

Increasing CIsco 1200 AP Throughput

Hi,
I'm having a problem achieving good performance on a Cisco 1200 AP [802.11b] which supports about 15 clients. It's been configured to allow only 11MB & 5.5MB access with static WEP & w/o SSID broadcast. But somehow the performance is way below satisfactory & it took about half an hour just to copy a 500MB file between 2 computers. Is there anything that i may had missed out during the configuration? Please advice, Thanks!

Check the 1200 error counters (under radio interface Detailed stats) and see if CRC errors are increasing in huge amounts. If yes, this could be a cause for the slow down. You might be experiencing interference. Did you do a site survey (including scanning the surrounding for interference) before installing the AP.

Wireless client can't get an IP but can associate with the Cisco 1200 AP

Hi!
Good day to everyone.
I guess i need some help with regards to a problem of mine.
I have a Cisco 1200 AP with IOS 12.3(2), the client is MS Win XP on an IBM notebook with an onboard intel wireless client.
the RADIUS server is a MS IAS and it is integrated with MS Active directory where I authenticate.
somehow the client can associate with WPA and TKIP however it won't receive an IP add after logging into domain. I have tried clearing out the TKIP and WPA and leave authentication open and guest mode on the config. this would be successful.
I also want to ask what does the "list_name" on the methods of authentication on EAP? Is this a RADIUS server's name or the AD server's name?
Attach is the configuration I made on the AP.
Thanks in advance,
Chris

I have this same issue, it seems the AP is not supplying the group key needed to complete the authentiction...so your being authenticated, but not fully with the AP. I have a sniffer of a good connect and a bad one, its got something to do with the key (if you look at the link status, you will probably see something like this beside security
TKIP, WEP, Key Absent
The Key Absent portion is bad. Its whats stopping us from getting fully "connected" with our AP's, but i have yet to figure out why.

I might have an answer for you... or I might be COMPLETELY WRONG
If it isn't just a "failed" upgrade, as in you've tried the upgrade again and it still is happening.... I was reading something about older APs not have a Manufacturing-installed certificate (MIC) and these AP's generating a Self-signed Certificate (SSC).
The error you have is referring to SSC so I'm writing this as if you have not had to previously do this step for your other conversions.
I believe a couple of things needs to happen for SSC AP's.
1) Must enable controller to accept self-signed certificated.
Security > AAA > AP Polices > Accept Self Signed Certificate > Apply
2) Add AP to Authorization List in Security > AAA > AP Polices > Add AP To Authrorization List
Enter MAC Address of the AP
Certificate type = SSC
SHA1 Key Hash can be obtained from the controller by issueing this command:
"debug pm pki enable"
Look for the line: sshpmGetIssuerHandles: SSC Key Hash is XXXXXXXXXXXXXXXXXXXXXXXXXX
I believe you use the XXXXXXXXXXXXXXXXXXXXX as the SHA1 Key Hash.
3) If required, you may also need to add the AP MAC Address in the Mac-Filter: Security > AAA > MAC Filtering > New >
Hopefully its either a reload of the software or this SSC thing that fixes the problem....

Cisco AP1121G Workgroup Bridge Problem

Hello,
For reference I have attached the following:
Network Diagram
Ping Results Table
Configurations for 1811 router, ap1121g root access point, ap1121g wgb.
I am seeking assistance with the following problem.
Referring to the attached network diagram, I cannot communicate past the ap1121g-wgb in either direction.
Also attached is a result table of ping attempts through the ap1121wgb from each side.
I don't have a problem with the wireless connections. The ap1121g's associate ok.
Based on the ping results the problem appears to be in the ap1121g-wgb configuration, but I have run out of ideas.
The following two cisco documents have been my main reference, besides the cisco command lookup site.
http://www.cisco.com/en/US/customer/products/hw/wireless/ps430/products_configuration_example09186a00805b9b87.shtml
http://www.cisco.com/en/US/docs/wireless/access_point/12.4_21a_JA1/configuration/guide/scg12421aJA1-chap19-wgb-standby.pdf
Any insight will be greatly appreciated.
Thanks...

Robert,
Going back to your original post and looking through the example given in the first URL, I spotted a few lines in the example configurations which apply to older revisions of code, but not newer AP code, so they may be misleading. Based on the parameter availability of station-role workgroup-bridge in your last message, would you be wiling to try the following?
Reset both 1121 APs to factory default configuration (#write erase -- do not save config to startup if prompted)
Give each AP an IP address on BVI1 so that both APs are in the same subnet
Apply the following configuration to the infrastrucuture (root) AP:
dot11 ssid WGB-SSID
authentication open
interface dot11radio 0
ssid WGB-SSID
station-role root
no shutdown
Apply the following configuration to the workgroup-bridge (client) AP:
dot11 ssid WGB-SSID
authentication open
interface dot11radio 0
ssid WGB-SSID
station-role workgroup-bridge
no shutdown
The intended goal with this exercise is to get rid of all config and to try only basic required elements of a WGB configuration, starting with fresh factory defaults. Let's see if it will work for you as a bare-bones setup and then you can add other configuration like encryption and ACLs back in later.

How to change Cisco EPC2425 into bridge mode

Hi,
I need help regarding how to chage ECP2425 into bridge mode. I have Wireless NAS drive router which has its own DHCP and NAT service. At the moment my Wireless Timecapsule (NAS Drive) is in bridge mode and connected to EPC2425 with ethernet cable. Everything is fine. But in order to access my timecapsule over the internet, I need to use its (timecapsule)'s NAT service. For this, I need to put EPC2425 which is my first point of access from internet, into bridge mode or atleast disabled its (EPC2425) NAT service. Unfortunately, I am not been able to find NAT or Bridge mode option on EPC2425. I will appreciate if anyone can help me out in this case. I need to change my EPC2425 router into bridge mode or gateway mode.
Thank you very much

Cisco 1530 Wireless Bridge distance

Hi,
I would like to share the internet in the outside area placed around 450 - 500m away from the main building (there is a line of sight).
Is it possible to do this using two Cisco 1530 APs? Please see below, if that makes sense:
Gateway <--- Ethernet ---> Cisco 1530 - 2.4GHz <--------- 500m --------> 2.5GHz - Cisco 1530 - 2.4 & 5GHz WiFi client access
1. What is the maximum distance to set them up as a bridge?
2. I assume it`s quite far away, what antennas would be the best to achieve best performance?
3. If I would like to set up a guest access and/or a landing page, would I need a WLC or maybe 1530 give similar options?
4. Any other advice in terms of design or configuration would be appreciated.
Thanks in advance.

Here is an example of the switch config I was testing:
If I use a config like Gi1/0/11 the bridge works for VLAN 500 only
If I use a config like Gi1/0/12 the bridges fail
interface GigabitEthernet1/0/11
description SWITCHPORT
power inline never
switchport access vlan 500
speed 100
duplex full
spanning-tree portfast
interface GigabitEthernet1/0/12
description TRUNKPORT

switchport trunk encapsulation dot1q
switchport trunk native vlan 500
switchport mode trunk

Cisco 1400 Wireless bridge

I cannot seem to find a place/way to set the time and date with the web interface.

Thank you, Beth. Your post was very helpful. I have printed the first two documents and added them to my documentation. Cisco has some very detailed documentation (200+ pages) for other pieces of hardware (switches and routers), and I was hoping there was similar documentation on how to implement, manage, and troubleshoot Aironet Bridges, Routers, and APs. I was looking for something to read that was newer that the Textbook used in the Cisco Networking Academy Wireless class, since the models described in the that text are several generations older. Thank you for your assistance.

Bridge and AP, using a 1200 series bridge.

Hi Folks,
I would like to bridge from an AP1131 to an AP1262 using the 5.8 ghz radios then allow access via the 2.4 ghz radio on the 1260. I will use a directional antenna for the 1260 bridge to optimize performance. The 5ghz radio will only be used for bridging. The ap 1131 is an AP right now but only offers access on 2.4 ghz. There are only a few clients.
The 1130 will be sitting in a window with the ant5160 outdoor mounted and pointed at it from ~200 feet away.
Does anyone see an issue? Maybe suggest a better parts list. I was originally thinking of using a 1310 as the bridge and a 1140 as the AP but that configuration is not as flexiable and the 1310 part is very old... I understand I will not get N throughput since the 1130 is not N capable, it is already installed. I need autonomous AP and can upgrade to 1140 in the future to improve performance.
I plan to upgrade to WCS next year, does it support this type of configuration? I am assuming that IOS does...
So here are the part numbers that I plan to use.
AIR-AP1262N-A-K9
AIR-AP1131AG-A-K9
Directional 5.8 ghz
AIR-ANT5160NP-R=
Omni 2.4 ghz
AIR-ANT2430V-R=
Thanks for any help,
Joe

Joe,
I am a little confused by your post but can offer some answers.
First of all I assume your intending to purt the external antennas on the 1262 not the 1130.
In terms of configuration you will need to configure 1 of the 802.11a radios in either the 1130 or the 1262 as a station role of root and the other in station role of non-root, that will enable them to connect to each other and bridge, then you can configure the 802.11b/g radios any way you choose and everythign should work as I think your intending,
over this distance you may get decent speeds. I'd be more inclined to use 1262's on each side with appropriate antennas; depending on what exactly your trying to accomplish on each side as far as coverage goes..
In terms of moving to WCS and lightweight mode it really doesn't support this configuration.
