Bridge links

I had thought, perhaps I was imagining it, that Bridge registerd itself to handle bridge:// URIs so I could load a Bridge URI in Bridge through a simple link, for instance emailed to a colleague and clicked on in their email client.
The requirement is straightforward - I need to automate routing files through multiple users, each using Bridge to access files on a shared fileserver. The first stage I was going to simplify with a script - an AppleScript hosted in the Dock - which an initiating user would drop a folder on... it would allow them to enter a quick comment, and then generate an email containing the comments and a link to the dropped folder to the intended recipient. The recipient - a tech-challenged user - would receive the email, click the link, which would load Bridge and navigate them to the selected folder.
This is a stopgap solution while we work on a broader, fully automated workflow leveraging our DAM. At the moment I just need a simple way for a remote user to help the recipient locate and navigate to the selected folder. I can just as easily host this script in Bridge in a JavaScript - that's not an issue - but I guess I must have imagined a bridge:// URI mechanism. Or did I?

OK,
So the scenario I have is vehicule to vehicule bridge links. The objective being any one vehicule can associate to any other one vehicule.
The first puzzle is about root/non-roots. For example, if you put a root in one vehicule, then it will not associate to other root bridge vehicules, and similarly with non-root ends.
So I thought I could put a root and a non-root in a vehicule. That way, when two vehicules approach, two bridge links come up between the vehicules.
However, what I am trying to stop is the root & non-root bridges from the same vehicule associating to each other...
Any ideas?

AP mesh info in WCS not show bridge links.

Hi guys,
I would like to know if any of you following problem has occurred. I have implemented 3 wireless mesh with 1262 AP WLC 5508 v 7.0.116.0 and WCS 7.0.172.0 base lic, all has been running perfect, the problem arises when I want to see on the map graphically bridge links, I have enabled AP Messh info but it not shows the bridge links, in hierarchical Mesh Parent-Child View only shows the RAP. To load the maps we used Campus> Outdoor area> AP.
I will appreciate any comments.
Greetings.

Are you loading 4.0? With WCS 4.x you need to generate a license with the PAK you should have received from Cisco. If you did not receive a PAK, read the following excerpt from the following url:
Existing Cisco WCS customers that have not received their PAK certificate from Cisco should contact their Cisco sales representative or send an e-mail to the [email protected] alias to notify Cisco that they need their PAK certificate. Cisco will attempt to respond to requests to this alias within 48 hours Monday-Friday 9AM-5PM Pacific Standard Time.

Encrypting Aironet 1410 bridge link using multiple VLANs

I've looked at the documentation available for Aironet 1400 series, and still would like to see a single document showing an example of
the best encryption/authentication available for bridge links using multiple VLANs.
As I understand it, 1400 series can support WPA-PSK using AES, which would work for me. I just can't picture how to integrate chapters 9 and 10 for the 'WEP and WEP Features' + 'Configuring Authentication Types' instructions.
I'm looking either for an example config, or a step-by-step that did all steps consecutively.
Thanks

What doc are you refering to? If you want to encrypt the link from root bridge to non-root bridge, then WPA/TKIP-PSK is what you should use. Here is a link to how to setup your link ssid to WPA: http://www.cisco.com/en/US/docs/wireless/bridge/1400/12.2_15_JA/configuration/guide/p15auth.html#wp1044935
Don't worry about the example they show on the WEP, just use the configuration from the above link for your encryption.
Configuring a VLAN
Configuring your bridge to support VLANs is a five-step process:
1. Create subinterfaces on the radio and Ethernet interfaces.
2. Enable 802.1q encapsulation on the subinterfaces and assign one subinterface as the native VLAN.
3. Assign a bridge group to each VLAN.
4. (Optional) Enable WEP on the native VLAN. <-- Use WPA-PSK
5. Assign the bridge's SSID to the native VLAN.
http://www.cisco.com/en/US/docs/wireless/bridge/1400/12.2_15_JA/configuration/guide/p15vlan.html
Here is an example of vlan 1 (native) will be your management and your wireless link. vlan 10 & 20 will pass through the link.

Point to Multipoint Bridge Link

I am currently working on a wireless solution at a campus that has a main building (Bldg A) and two remote buildings (Bldg B & Bldg C). The two remote buildings each have a 1232 access point that provides wireless access to the Internet via Linksys ADSL routers. At Site A there are 5 x 1232 access points providing wireless access to the LAN.
At each remote site the client wishes to discontinue the ADSL service and connect the access points to the main network at Bldg A. Bldg B is 80 metres from Bldg A and Bldg C is 30 metres from Bldg A. Bldg B & C are both in a 30deg beamwidth of the antenna at Site A. There is no Ethernet cabling connecting the sites so a bridge link will be required. The client requires a voice grade WLAN.
I am proposing the following solution
- BR1310 bridge with integrated antenna at Bldg A (root bridge) or a directional antenna such as a yagi or sector antenna.
- BR1310 bridge with Omni-directional antenna mounted on the roof of Bldg B (non-root bridge) associating to the root bridge at Bldg A
- Existing 1232 AP with 2.2dBi dipole antenna at Bldg C (non-root with clients) associating to the root bridge at Bldg A and providing wireless access to clients.
Can anyone advise if I can connect the Ethernet port of 1232 AP at Bldg B to the Ethernet port of the BR1310 (non-root bridge) to provide wireless access to clients via the 1232 AP. My reason for wanting to use the 1232AP is that I am not confident that the Omni-directional antenna will provide adequate signal penetration through the corrugated roofing steel.
Originally I wanted to use 1232AP?s with the ?A radios? providing bridge links and the ?G radios? providing wireless client access but from what I have understand the AP1232 can only be used in point to point configurations.
Thanks for your help.

I was going to have the same concern as you about using the 1232 for both bridging and client serving. Tying a bridge and an AP back to back is a valid configuration from what I have heard. I haven't had the opportunity to try it, though. I know that Cisco says tying 2 bridges back to back to serve as an intermediate bridge hop is a valid configuration, so I don't see why this would be any different.

The 'Browse in Bridge' link is not active in Fireworks

I am doing the classroom in a book for fireworks cs5 and I am trying to use bridge. There is a link in Fireworks that says 'Browse in Bridge' but it is faded out meaning I cannot click it. There is also a button for bridge but nothing happens when I click it. Also, in Bridge itself, when I click Tools there is no Fireworks option. There is a Photoshop option. In other words, Fireworks and Bridge are not linking together. How do I get them to link together?

Hi there:
Just it sounds like the link between the two apps was broken somehow. If possible, reinstall Fireworks CS5 and then Bridge CS5 should see it. Also, confirm that you are using a matching version of Bridge (not CS4 or CS6).

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.

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!

VoIP across a point-to-point (bridge-to-bridge) link

Hi,
I have 2 sites with Voice-enabled routers installed. They are connected to PBX in both sites.
These sites are connected to each other via a 2.4Ghz 802.11b wireless connection using Aironet 350 bridges.
The link is currently used to carry voice only (no data traffic transmitted over the link).
Connection is operating at 11Mbps but configured to fallback to lower speed in case it is needed. Statistics show that connection is operating at 11Mbps for the majority of the time.
Same connection had previously been tested with data traffic and no problem was noticed.
The problem is that when more than 5 simultaneous G729 voice calls are transmitted over the link, the voice quality gets degraded.
We have also tried to use the same link for Voice and Data at the same time, we have also noticed that at the 6th call, the quality gets degraded (i.e. with and without data being trasmitted on link at the same time as voice, we are getting choppy voice quality starting the 6th call).
Thanx

Hi There,
actually the limitation turned out to be in the pps rate of the 802.11b bridges. In summary the limit seems to be around 5 to 6 calls, may be a bit more (also depending on the data tranmitted over the link).
Despite the fact that we have enough bandwidth the voice is choppy and we are not able to use it properly. This issue has been confirmed with Cisco and there is no workaround. We will try 802.11g, may things will be a bit better.
Regards

1410 Bridges link fail

Hi,
I have a point to point link of 9.27 km using 1410 bridges and AIR-ANT58G28SDA-N antennas as per the documentation that would be an easy to deploy link and it should work at 54 Mbps, eventhough it drops the link, it's so slow and the power measurments indicate -70 dbm (aprox) right under the antenna which is at 9 m height.
This is not the first time I have troubles with 1410 bridges, the other two times I had to change them for 1310 bridges. I wonder if it has to do with some configuration tunning like, external antena gain, link distance or anything else? By the wat this is ocurring in México don't know if that might be worth of taking into consideration in order to deploy a 1410 link.
Please let me know if you need to know any other information to figure out the scenario.
Thanks in advance!
Roberto.

Take a look a the specs of that antennae. IT's a parabolic dish with a narrow beam
http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a008022b11b.html
4.75°H, 4.75°V is the beam width. if you are standing 9m below the antannae, -70 is pretty impressive, since you're getting bleed signal.
What does the signal look like up by the antennae? What errors are you seeing in the logs on the bridges? Are there any trees that could be blown into the way?
Cheers,
Steve

Bridge link with two aironet 1242

Hi to all,
I want to connect with wireless devices two buildings, one in front of another.
Short distance (about 20 meters) and no obstacles.
I have a couple of aironet 1242 and i was wondering if it would be possible to setup this link with this equipment.
could WGB be the solution?
thank you very much

WGB could work, if you do not need to extend multiple VLAN across the link, and you have less than, I want to say 200, devices.
What you might want to look into is Root/ non-Root bridging.

Bluetooth, Blackberry bridge and Playbook not linking to Q10

Please.....
After checking settings and browsing the Internet for possible problems or fixes, I'm having frustrating problems in linking my phone and playbook when they worked fine before a few wks back, does anyone know if this has been a recent problem or if this has been resolved, it does seem a waste of my 64gb playbook if I can no longer use Blackberry bridge (link from Q10 still doesn't do what it is meant to do as it did with me 9800) or bluetooth link up? Please i'm going spare here trying to fix or search for updates that always say 'unavailable for this device', starting to regret getting my new Q10 that i've had for 3mths where bridge doesn't work, bluetooth doesn't get connected properly and useful apps are not available for new Q10 device, my playbook worked wonders with my 9800!
CTEvans

Your Playbook will never work with the Q10 like it did with with your 9800. That's just the way it is.
I would try disconnecting both devices, unpair them, and then reboot both devices and reconnect using the Bridge app. Once they do connect about all you can do access the Internet on the Playbook using your Q10.

Wireless Bridge Resilient Trunk Link

Hi Community folk,
I need some advice on how to set up a dual (resilient) wireless bridge link.

I have each pair of bridges configured trunking vlan 82 native and user vlan 570. Individually they are fine and I get management access on vlan 82 to both bridges and the switch at the remote end of the link, clients patched in to the switch at the remote end in switchport access vlan 570 also get the correct IP address and subsequent access to network resources, individually they are working well. rapid pvst is configured across the network as there are dual 1Gb connections to all access layer switches and this also works fine. My problem is when I enable the second bridge link, this seems to cause a network loop and essentially takes down the whole network, I have left it for a while to see if spanning tree convergence is taking a while but no luck, as soon as I disable the second link everything calms down and I have a good network again. I am posting my root and non-root bridge configurations here but only one of the pairs, the other pair is configured identically but has a different SSID, PSK and channel configured:

Hi Rockford,
This should be possible. Check the primary switch set to spanning tree root for your vlans & two different bridges connected ports having different STP port priority for vlan 82 & 570.
Since you are having STP loop I think ports get shutdown.
In case if could have L3 seperation between these two buildings, then you can load balance traffic between those two radio links. Here is a reference post which I posted some tested config for that scenario.
https://supportforums.cisco.com/discussion/12041146/good-solution
If I get time I'll see whether I can do similar thing for your config requirement

Unstable Wireless Bridge Connection via 802.11a(Radio 1) of Aironet 1242

Hi,
I'm going to setup up an AP 1242 in a remote area to support b/g client via a 802.11a bridge link (all using AP 1242).
Before the deployment, I tested the configuration in a lab environment. However, I found the bridge link will come up a while and suddenly gone. Resetting the root AP or the non-root AP cannot bring the connection up again. Sometimes, when I shutdown the b/g radio (radio 0) of the remote AP, the bridge link will be established again. Following is the log from the root AP.
Thanks!

Thanks dmantill for reminding me to revisit the antenna and related stuff.
As the setup is in a lab environment, the APs are put on a work bench next to each other, therefore, the radio output power was lowered.
After adjusting the output powers, it works as expected.
Thanks Surendra and dmantill.
