Aironet 1400 Point to Multipoint Bridging

Hello Everybody
I`m already desinging a Wireless Point to Multipoint Bridging with Aironet 1400. I was Wondering if on the Central point the 1400 should has a external omnidireccional anntena to support all the others bridges... that is: this AP will be the multipoint bridge.
Could I use all the 1400 AP with integrated anntenas and get that the Central AP work in a multipoint configuration?
Thanks in advance.

Hi,
Cisco Aironet 1400 has a model with integrated 22.5 dBi patch array antenna, the AIR-BR1410A-A-K9.
The integrated radio and high-gain integrated patch array antenna is used in point-to-point links and the non-root nodes of point-to-multipoint networks.
You can (need to) use the external omnidirectional AIR-ANT58G9VOA-N antenna type for your N-type root bridge unit (AIR-BR1410A-A-K9-N).
Basically, these models are ideal for each other in both point-to-point & point-to-multipoint connectivity scenarios.
Cisco 1400 N-type is recommended to use the following external antenna type:
* 9.0 dBi vertically polarized omni antenna --> you need this
* 9.5 dBi sector antenna with support for vertical or horizontal linear polarization
* 28.0 dBi dish antenna with support for vertical or horizontal linear polarization

Link Budget for Aironet 1550EU point-to-multipoint bridge

We have six remote building near our main office. Is it possible to use a single Aironet 1550EU as the root bridge for point-to-multipoint links to six Aironet 1530E on each building? The datasheet for Aironet 1550EU states that it support three 5Ghz antenna and three 2.4 Ghz antenna.
The remote buildings are within 1 km radius of the main building with LOS. We are using the following link budget for our calculation. Our target bandwidth is 24 Mbps. Please correct me if my number is incorrect. I am quite new to wireless network.
Regulatory Domain: America
Link Margin: 5 dBm
Cable link loss: 2 dBm
Antenna Gain for both 2.4Ghz and 5Ghz links: 13 dBi Patch Antenna
Max Tx Power of 1550EU for 802.11g and 802.11a with 13 dBi antenna : 20 dBm (smallest Max Tx power on channels)
Rx Sensitivity of 1550EU and 1530E for 802.11a and 802.11g @ 24 Mbps: -81dBm
Max Range for 5 Ghz @ 24 Mbps = 4.78 km
Max Range for 2.4 Ghz @ 24 Mbps = 9.95 km
I am using the formula on this page. The result is very similar to Bridge Range Calculator from Cisco. Is my calculation correct?
Thanks

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.

Bandwith on a Point-to-Multipoint Bridges

Hello everybody..
I`m already designing a point-to-multipoint bridging with Aironet 1300. On the central site I have a omnidirectional antenna and on the remote site integrated antenna. The question is: How much bandwith could I get if my topology is 1 central site a 5 remotes sites?
Does the 54Mbps bandiwith is share between 5 point or does each one could get 54 Mbps.?
Thanks in advance...

Hi Edgar,
Have a look at the following excerpt;
Point-to-Multipoint Bridging
In a point-to-multipoint configuration, two or more non-root bridges associate to a root bridge. Up to 17 non-root bridges can associate to a root bridge, but the non-root bridges must share the available bandwidth.

Aironet 1310 Point to Multipoint Configuration.

According to the installation manual in a point to multi point configuration one device should be a root-bridge a the others must be non-root bridge. This is working fine. From the root bridge I can see the true CDP and ping the other devices. with out any problem. Even Http and set up the non-root bridge?s configuration.
The problem begins when I am trying to ping from a non-root bridge to another non-root bridge and have access to the resources in that side of the Lan.
The ip Addressing scheme seems to be fine , all the devices are in the same sub-net. Know what am I missing in the configuration of the root bridge so he can permit the communication between all non-root bridges?
TKS

I didnt have the time to check your configuration but I can give you a link that mind help you. I try it as point to multipoint and i could ping between the two non root aironet

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.

Which cisco wireless bridges support point to multipoint

hi all i am really new to wireless. i am looking for information as which cisco wireless bridges support point to multipoint configuration.
i have a cisco 1230G access-point will it support the same .
any help would be great.
regards
sushil

The Cisco 1300's and 1400's support point-to-point and point-to-multipoint. The 1230G can only support point-to-point (i think)

Troubleshooting Point to Multipoint Wireless Bridge

I have a customer which is a Small RV Park that has Four 1242 Dual Band Access Points with external outdoor antennae.   All 4 APs are configured with a client SSID on the 802.11G radio, and an Infrastructure SSID on the 802.11A radio interface.   The A band is being used for wireless backhaul from the 3 remote APs to a central AP configured as a Root Bridge.   The 3 remote APs are non-root bridges on the A Radio interface.
There are separate antenna on each AP for the 2.4ghz and the 5ghz bands. Directional patch antennae are on the remote APs on the A band pointing to an 5ghz Omni on the Root Bridge. On the 2.4ghz band that the client PCs use, their are either Omni or 180 degree patch antenna on those interfaces.
The issue I am having is keeping all three 802.11A back haul links up at the same time for an extended period.   I moved some of the 1242 APs in the park to get better client coverage, and all three remote radios worked with the backhaul link working at 54mbps. Then I started having issues with one radio dropping its backhaul link, while the other two remotes worked perfectly. Then a second AP backhaul link failed.   I was then able to reconnect the radio I was initially having issues with changing the root bridge channel selection from manual to DFS.
The Second remote AP still has not reconnected, but remote APs 1 an 3 are still up. I have checked the antenna alignment visually, and checked the connectors.   Even swapped out a spare AP. All 1242s are running the last software version put out for that model.
Any suggestions on how to troubleshoot this? When I do a shut/no shut on the dot11radio1 interface, I get a console message that it finds no radio to associate. The Infrastructure SSID has no security on it and open authentication. This is just for free internet access to anyone in the RV Park.

Point to multipoint with AP 1230AG

Hello,
I want to do this configuration:
Site A must be connected to site B and to site C. On the site A there is an AP 1230AG, it's configured in bridge mode in point to multipoint to site B and C in 802.11A.
On the site B there is an AP 1230AG, it's configured in bridge mode in point to point to the site A in 802.11A, and it's configured in access point in 802.11G for laptops.
On the site C there is an AP 1230AG, it's configured in bridge mode in point to point to the site A in 802.11A, and it's configured in access point in 802.11G for laptops.
I believe that it's possible to make bridge and access point on the same AP in point to point , but is it possible in point to multipoint with AP 1230AG?
Thanks and regards.

As long as there are dual radios each radio can be configured as both as access point and brdige mode.

Outdoor WiFi Point-to-Multipoint Root redundancy

Hello,
In an outdoor wifi setup connecting main site to remote sites through point-to-multipoint design, if the main building AP root bridge fails, all the remote sites will be out of network. How shall we achieve redundancy in case of the main site failure?
I have a possibility of another building (second main building) with wired medium to split the entire wireless domain, in which I can install a new root bridge catering 50% remote sites. The first 50% sites will be connected to Main site 1 root bridge and rest 50% to Main site 2.
Is this a valid design?
Is it possible to fall back non-root AP from Main site 1 root to secondary site root?
Can a non-bridge AP fall back to another Root bridge?
Or any other valid design to achieve root level redundancy?
The total campus coverage area is 2 km.
Thanks in advance!

Increasing Mesh Availability
A wireless mesh cell has similar properties to the cells used to create a cellular phone network. The technology may define the maximum size of the cell; smaller cells can be created to cover the same physical area, providing greater availability or capacity. This is done by adding RAPs to the cell. Just as in the larger mesh deployment, the decision is whether to use RAPs on the same channel, as shown in Figure 8-16, or use different channels, as shown in Figure 8-17. The addition of RAPs into an area adds capacity and resilience to that area.
Figure 8-16 Two RAPs per Cell with the Same Channel
Figure 8-17 Two RAPs per Cell on Different Channels
Multiple RAPs
Before deploying multiple RAPs, the purpose for deploying these RAPs needs to be considered. If additional RAPs are being considered to provide hardware diversity, they should be deployed on the same channel as the primary RAP. The reason for this is to minimize the convergence time in a scenario where the mesh transfers from one RAP to another. When planning RAP hardware diversity, the 32 MAPs per RAP limitation should be remembered.
If the additional RAPs are being deployed primarily to provide additional capacity, the additional RAPs should be deployed on a different channel from its neighboring RAPs to minimize the interference on the backhaul channels.
When adding a second RAP on a different channel, channel planning or RAP cell splitting can be used to reduce the extent of potential collision domains. Channel planning allocates different non-overlapping channels to RAPs in the same collision domain to minimize the collision probability. RAP cell splitting is a simple, yet effective, way to reduce the collision domain. Instead of deploying one RAP with omni-directional antennas in a mesh network, two or more RAPs with directional antennas can be deployed. These RAPs are collocated but operate on different frequency channels, thus dividing a large collision domain into several smaller ones that operate independently.
If the Wireless Mesh bridging features are being used with multiple RAPs, these RAPs should all be on the same subnet to ensure that a consistent subnet is provided for bridge clients.
If you build your mesh with multiple RAPs on different subnets, MAP convergence times can increase in the event of a fail over as the MAP has to failover to another RAP on a different subnet and DHCP for an appropriate IP address. One way to limit this from happening is to use different BGN for segments in your network that are separated by subnet boundaries. In segmenting in this manner, MAPs do not associate with a RAP on a different subnet and you avoid slow convergence issues and the expense of the higher availability offered by the additional RAPs.
Hope that helps.

Point 2 Multipoint Video

Hi,
I have CUCM 6.0.1 running with IP Phones 7985G. Point-to-Point video calls are working fine. But when i add another video phone to the call all the phones start displaying their self videos.
Does anyone know how to configure Video Phones so that i can have Point-to-Multipoint Video calls as well as video confernces.
Thanks

I have already configured software conference bridge on CUCM and audio conferencing is working fine even on video phones.
What my concern is that videos are not being conferenced, i.e. on point-to-point call both person can see each other at the phone display. but when i conference it on 3 or more person everyone see their own video NOT other party's.
Any help.

Dynamic VLAN Assignment with RADIUS Server and Aironet Access Points

Hi Guys,
I would like to go for "Dynamic VLAN Assignment with RADIUS Server and Aironet Access Points 1300". I want the AP to broadcast only 1 SSID. The client find the SSID ->put in his user credential->Raudius athentication->assign him to an specific vlan based on his groupship.
The problem here is that I don't have a AP controller but only configurable Aironet Access Points 1300. I can connect to the radius server, but I am not sure how to confirgure the AP's port, radio port, vlan and SSID.
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008076317c.shtml#switch
I go through some references:
3.5 RADIUS-Based VLAN Access Control
As discussed earlier, each SSID is mapped to a default VLAN-ID on the wired side. The IT administrator may wish to impose back end (such as RADIUS)-based VLAN access control using 802.1X or MAC address authentication mechanisms. For example, if the WLAN is set up such that all VLANs use 802.1X and similar encryption mechanisms for WLAN user access, then a user can "hop" from one VLAN to another by simply changing the SSID and successfully authenticating to the access point (using 802.1X). This may not be preferred if the WLAN user is confined to a particular VLAN.
There are two different ways to implement RADIUS-based VLAN access control features:
1. RADIUS-based SSID access control: Upon successful 802.1X or MAC address authentication, the RADIUS server passes back the allowed SSID list for the WLAN user to the access point or bridge. If the user used an SSID on the allowed SSID list, then the user is allowed to associate to the WLAN. Otherwise, the user is disassociated from the access point or bridge.
2. RADIUS-based VLAN assignment: Upon successful 802.1X or MAC address authentication, the RADIUS server assigns the user to a predetermined VLAN-ID on the wired side. The SSID used for WLAN access doesn't matter because the user is always assigned to this predetermined VLAN-ID.

Thanks.

I'm not sure if the Autonomous APs have the option for AAA Override. On the WLC, I can go into the BSSID, Security, Advanced, and there's a checkbox that I would check to allow a Radius server to send back the VLAN.
I did a little research and it looks like the 1300 may give this option but instead is defined as "VLAN Override". I've found the release notes for 12.3(7)JA5 (not sure what version you're running) that give mention and a link to configuring EAP on page 4: http://www.ciscosystems.ch/en/US/docs/wireless/access_point/1300/release/notes/o37ja5rn.pdf

Site to site vpn for multipoint bridged connection

I have a point to multipoint wireless bridge connection that the customer wants to secure with an ASA 5505 at each location. Keep in mind that each remote is just an extension of the host network, all on the same IP range.
I was thinking that I could just setup an ipsec tunnel to each location from the host. Every example I see uses a different IP range for each location.
My question is, is that possible and how would I do that?

No, the ASA can't bridge across IPSec VPN connections (I don't believe any IPSec implementation by any vendor directly supports bridging), so I don't think there's an easy solution. If you had IOS routers you could configure bridging across GRE tunnels, even that's not supported by Cisco so you'd still be pushing your luck a little bit. Probably the best solution would be to just bite the bullet, re-address the remote sites, and configure traditional site-to-site VPNs. You could try to get fancy and do NAT across the VPNs so that all the remote hosts would appear to be on the same subnet as the main site, but I think you'd just be asking for trouble doing that.

Aironet 1400 Security

I have users offsite connected to the main network via Aironet 1400s. In the past we have used port security statements on a 2950 to allow only specific Mac addresses on the link.
I have had to setup a second vlan at this remote location and as a result I have trunked the port, which prevents me from using port security statements.
I thought about using a RADIUS server, but after doing some reading it looks like it will only authenticate the non-root bridge, not the clients connected to it.
I considered using access lists but I want to be able to log any denials/security violations, and this is not an option when using extended (700) access lists.
Any suggestions would be appreciated.

You can configure the AP to authenticate the users,
