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

BR1310 Wireless Point-to-Point Bridge

I recently configured two BR1310 Access Point/Bridges into a Root & Non-Root (without clients) configuration to extend a LAN to another building. I configured the units to use LEAP (Root acting as Radius server), authenticating with Network-EAP w/ WPA2, and AES as the encryption cipher. Being that WPA2/LEAP handle the key management, I had a question regarding best practices. I currently have configured a "dot1x timeout reauth-period" of 300 seconds, in addition a broadcast-key change of the same. I have 4 VLANs trunked over this bridge, and since I have no wireless clients associating with these bridges, I'm assuming I do not need the broadcast-key rotation. The idea is that by forcing a dot1x reauth, a new PTK/PMK will be created every 300 seconds. Is that a recommended practice?
Also, being that I have 4 VLANs trunked across these bridges, is there a way to verify (via debug?) that all VLANs traffic is being encrypted by AES? Obviously when I do a "show dot11 assoc all", only my native VLAN (mgmt) shows as AES, no other VLANs.
Thanks,
Dan

Hello,
it normal that you only see with "sh dot11 ass .." the native vlan. On this vlan (infratstructure) will be realize the authentication and encryption. That means not,
all other vlan,s are not encrypted !! Of course they are, because the vlan,s will be "transport" sequential in the AES encrypted connection. You can by the way see this with a WLAN-ANALYSOR.
The timeouts (reauth-period) not so low I use 10000 sec. It is not mor secure If you so often reauthenticate the session.
A Cisco staff had by my customer configured 40000 sec. A good choice is once per day.

VLAN info across a Point-to-Point WAN circuit

What is the best way to temporarily pass VALN info across a Point-to-Point T1 WAN circuit. Here is a simple layout:
I have a 355012G at the Corporate Core with several VLANs for domain login, IP phones, file servers, printers, etc. I have a remote location that is currently getting the VLAN info across a wireless bridge (2 1300s and a 3500XL switch at the remote warehouse. The customer wants to connect the remote site with a Point-to-Point T1 and a new 35660 switch as follows:
MAIN-------------------------------------------REMOTE
355012G---e---3560R--------P-to-P------2610R--e--3560
What would be the best design / config scenario for passing the CORE VLAN info across the WAN P-to-P?
I was thinking bridging?
Any thoughts?

I have been thinking about this for a while and I can't find a way to do it. I know you can do embedded trunks but that is not what you are asking to do. The only alternative you have is to bridge the traffic.
Sorry can't be more helpful than that but since no one else has responded I figured I would giev my 2 cents for what it might be worth.

How can I set up a guest access point with a Time Capsule and an Airport Extreme? I am using a Telus router with the Time Capsule used as a wireless access point (bridge mode). I don't want the guest access point to have access to my network.

How can I set up a guest access point with a Time Capsule and an Airport Extreme? I am using a Telus router with the Time Capsule used as a wireless access point (bridge mode). I don't want the guest access point to have access to my network.

The Guest Network function of the Time Capsule and AirPort Extreme cannot be enabled when the device is in Bridge Mode. Unfortunately, with another router...the Telus...upstream on your network, Bridge Mode is indicated as the correct setting for all other routers on the network.
If you can replace the Telus gateway with a simple modem (that performs no routing functions), you should be able to configure either the Time Capsule or the AirPort Extreme....whichever is connected to the modem....to provide a Guest Network.

1300 Series Access Point/Bridge Power Injector - Using power over ethernet

Can I use power over ethernet to supply the Injector with power?

Hi Mikael,
Sorry, this will not work. Have a look at these specs;
1300 Series Power
Power
The access point/bridge receives inline power from the Cisco Aironet Power Injector (hereafter called the power injector). Dual-coax cables are used to provide Ethernet data and power from the power injector to the access point/bridge. The power injector is an external unit designed for operation in a sheltered environment, such as inside a building or vehicle. The power injector also functions as an Ethernet repeater by connecting to a Category 5 LAN backbone and using the dual-coax cable interface to the access point/bridge.
The power injector is available in two models:
Cisco Aironet Power Injector LR2 standard version (included with the access point/bridge)
48-VDC input power
Uses the 48-VDC power module (included with the access point/bridge)
Cisco Aironet Power Injector LR2T optional transportation version
12- to 40-VDC input power
Note The power injector and the power module must not be placed in an outdoor unprotected environment. The power module must not be placed in a building's environmental air space, such as above a suspended ceiling.
http://www.cisco.com/en/US/products/ps5861/products_installation_guide_chapter09186a008079b93b.html#wp1051840
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. The Cisco Aironet 1300 Series Outdoor Access Point/Bridge ships with the Power Injector LR2 and an AC power supply.

WLC and Point-to-Point Bridge/Repeater

Hi all,
I have a WLC2125 and 11 LAPs installed in our warehouse. There is going to be one additional AP but the problem is we can´t provide cabling in that area. The idea is to have this additional AP connected to one of the existing LAPs and repeat the signal of it or to create point-to-point link, the question is, would LAPs and WLC support such configuration, is it possible at all? If so, please let me know the config process or some documentation.
Thanks in advance.

Hi,
Q> What do I gain by going for mesh topology?

Q> I can´t eliminate WLC from my network,
>> Mesh network will not work without WLC.
Q> instead I thought of leaving one LAP as autonomous AP and bridging it with the new AP that will not have a physical connection
>> The only way to Integrate the Autonomous AP to LWAPP AP is by using the WGB Mode, the REPEATER is not supported and even the Point to Point bridging. The WGB doesnot provide Wireless where in you can conect a switch and conect wired clients to it.

Autonomous Wireless Point-to-Point bridge

I am hoping someone can point me in the right direction.
I am having difficulty finding documenation on hwo to properly configure Cisco 1552e AP's in Autonomous Mode as Point to Point wireless bridges with just utilizing the wireless link as a backhaul, not client access. We have to go with autonomous because we plan on having Local Mode ap's (CAPWAP) terminated behind the MAP ethernet bridged port. Here is our topology:
Local Network (Controller resides on this network) ---------> L2 Switch ----------> RAP --------> wireless bridge <---------- MAP <----------> L2 Switch ----> Clients\CAPWAP AP's (servicing clients)
We want to pass all the VLANs we will need for both the wired network and CAPWAP network.
Thoughts?

This is extremely useful and the exact configuration we are looking to do.
Is there a limit on the number of Bridge-Groups that can be used (essentially number of VLANs)?
Also are you familiar with running Mesh AP's in autonomous mode? Do we lose any features other than management by moving them from CAPWAP to Autonomous?
We have to run these in autonomous because our MAP end will run 3602i local mode APs, so lame that Cisco wont support Capwap over CAPWAP based mesh bridge.

AP1242G Point-to-Point Bridge Configuration

Hi,
I have two Cisco AP 1242G and i'm trying to configurate a Point-to-Point Bridge Configuration to connect two wired LAN. Figure 1.8
http://www.cisco.com/en/US/docs/wireless/access_point/1300/installation/guide/130h_c1.html
I would connect two wired networks.
I tryed two configurations:
Root and Non-Root AP. This way every wired PC on the Root AP can connect to the Access points, but cannot connect to the wired PC on the Non-Root AP.
AP and WGB. Even this way the wired computers on one AP cannot connect to the wired PC on the WGB. This way only the wireless client can connect to the wired network.
Any advise? This is my network:
Root Bridge                                 Non Root Bridge
10.0.0.1                                      10.0.0.2
Wired clients on the RB                Wired clients on the Non RB
10.0.0.100                                   10.0.0.200

Thank you for the answer.

1310 point-to-point bridge in Lightweight mode

how is the 1130 point-to-point bridge work in lighteight mode ?
Is this supported on 5508 and on new 2500 series controllers?
How does the WCS manage the point-to-point link?
I am aware that there is Lightweight software for the 1300 series bridges but never used one so far

"Ethernet Bridging" is a feature within our Mesh Deployments. "Enterprise Wireless Mesh" (indoor mesh) is the name for using non-mesh APs 1130 and 1240 models (1140, 3500 I think are supported in 7MR1).
Anyhow, the general idea behind Indoor Mesh or Outdoor mesh is still the same....
One device closest to the WLC is the Root AP, a 2nd device associates as a Mesh AP, and if you enable Ethernet Bridging then all traffic can bridge from the MAPs ethernet interface to the RAPs interface, similar to an aIOS bridge....
But again, 1310 is not a supported model for mesh.
I guess this link might have more information?

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.

Create a tab that points to an external link ?

Hi,
Oracle 11g r2.
Apex 4.1.1.00.23.
I need to create a tab that points to an external link (actually a link to our old Forms application).
For the moment, I simply added the tab "manually" in the template by writing the needed HTML after the #TAB_CELLS# substitution string.
It works but it does not allow me to control authorization scheme, etc.
Is there any way I can create a tab without associating it to an existing page, but pointing to an external link ?
Thank you.
Yann.

Hi,
Create page zero to your app if you do not have one.
Create tab that lead to page zero.
Edit tab and check what is tab name.
Tab name (not label) is important as it is reguest when you press tab.
Create application process On Submit: After Page Submission - Before Computations and Validations like
apex_util.redirect_url('http://www.google.com');Set condition to process Request = Expression 1 and enter to Expression 1 your tab name (not label)
Regards,
Jari

HP Pavilion a1210n with Windows Vista 32bit. looking for audio drivers. Can you point me to a link?

Hello,
I have an HP Pavilion a1210n running Windows Vista 32bit. I'm missing the audio drivers and can't seem to find them. Can you point me to a link for these drivers?
Thanks, It's much appricieated!

I found this link but it doesn't talk about audio drivers in the multimedia package. Am I missing something? Does Vista need to have all OS updates installed for this to work?
Thanks again!

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.
