Aironet 1400 Interference?

I have an Aironet 1410 which has been online for the past 3-4 months with no problems at all. The other day we noticed these messages coming through (I have removed mac addresses and host names).
16 Jul 1 11:42:22 Warning Packet to client HHHH.HHHH.HHHH reached max retries, removing the client
16 Jul 1 11:42:21 Information Interface Dot11Radio0, Station <wireless-bridge> HHHH.HHHH.HHHH Reassociated KEY_MGMT[NONE]
16 Jul 1 11:42:08 Information Interface Dot11Radio0, Deauthenticating Station HHHH.HHHH.HHHH Reason: Previous authentication no longer valid
16 Jul 1 11:42:08 Warning Packet to client HHHH.HHHH.HHHH reached max retries, removing the client
This message then keeps repeating, and the link is almost unusable with regular timeouts to users and access to the remote 1410's web interface. Yesterday the messages stopped and the link is now as stable as it was before. Is this is an interference problem and is there anything I can do about it? I tried rebooting both devices and they switched to a different frequency (they are set to Least Congested Frequency) but this made no difference.

The message indicates that AP has failed to reach associated workstation over radio and therefore it (AP) deassociates workstation. The reason for this, apparenly, is reachability of workstation over Radio. Can you make sure that your workstation is in the good area of signal strength and quality? Also make sure that there's no nearby AP which has overlaping adjacent channels with the AP in the questions.

Question about aironet 1400 bridge

We are currently trying to set up a link
across the street using 2 bridges. My concern is more of a mounting one and what needs to be visible for the link to work
We are 13 stories up ..and the building across the street is 11 stories up...
We have purches the 9.5 dbi sector antenna. Can I keep the Bridge itself
on the inside and just mounth the antenna
on the outside? While reading the doc, it appeared that the Bridge itself had an antenna

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

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,

Aironet 1400 Ethernet

Hello all,
Help please!
The led "uplink activity" in the cisco aironet 1400 -power injector lr- is off. I have checked coaxial and connectors, they are ok. I can not access the bridge by ethernet or telnet. I have reseted the bridge also, but the signal keep off. Is it a software/hardware problem?
Thanks

If you trun the AP backwards, what lights do you see. There are three lights down at the bottom and there is a sequence in which they blink. Please keep an eye on the blinking LED's.

Cisco Aironet 1400 - security

Dear all,
I'm currently configuring 2 Cisco 1400 Bridges. One is the root bridge the other the non-root bridge (ok logic :-) ).
I wanted to know what is possible for using certificates for the non-root bridge or to use the local radius on the root bridge to increase the security level of the wlan network.
I tried to reach the local radius on the root bridge, but I'm always getting a 404 error. After reading some Cisco docs, it said that we need to use AAA new model from the CLI, I did it without success.
What would you recommend to ensure a good security level for the wireless link?
I'm open to use certificates or a Radius (local or IAS) or any suggestions you may have.
Any help or or suggestions are very welcomed...
Thanks per advance,
Regards

The only EAP types supported by BR1410 is LEAP. You should able to configure LEAP client on the non-root bridge:
http://www.cisco.com/en/US/docs/wireless/access_point/12.2_15_JA/configuration/guide/s15rep.html#wp1036921
The above URL is for repeater; however, it is the same for non-root bridge.
You may already know. If you want to set up local radius server, the following URL should be useful:

Aironet 1400 Bridge with IAS

Hi,
If the 1400 root bridge is configured for EAP, what are the options for EAP authentication methods to be configured on a Microsoft IAS radius server in order to authenticate the 1400 non-root bridge?
LEAP is out since it is not supported on IAS, so what are the available options other than using static WEP keys?
Thanks

According to
http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140val-all.htm (701)
the 1410 is not on the list. Now this could be because the 1410 is EOL.

Diffs between Aironoet 1300 and 1400

Gurus,
We paid an outside firm to set us up with a wireless shot connecting our two facilites, 2 miles apart. They used Aironet 1400 bridges, that pass both Data and CCME VoIP traffic, and a few Vlans.
Our company may take posession of another building only about 1/2 mile away from the existing main site, where one of the 1400's is located. Wireless has worked well for us so far, and I would plan on setting up a wireless link to the new site as well.
The 1300's and 1400's are substantially different in price, and I was wondering what the difference is between them, at least for my application.
Thanks,
-Michael

The 1300 series is basically a 1231G with a coax-based power injector built into a weather proof plastic case. It operates only on the 2.4Ghz spectrum (802.11g) which as mentioned is crowded and potentially more subject to interference.
The 1400 series is a 5GHz spectrum radio (802.11a) which means it has 8 non-overlapping channels compared to the 1300s 3 non-overlapping channels. The device itself is a sturdy access point built from die cast metal.
The problem with the 1400 is that it doesn't support WPA2/AES. Or at least didn't the last time I worked with the bridges. The lack of WPA2/AES support means you will use LEAP to secure the link. LEAP is unfortunately vulnerable to a proliferation of offline attacks.

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.
BR# configure terminal
BR(config)# interface dot11radio0.1
BR(config-subif)# encapsulation dot1q 1 native
BR(config-subif)# bridge group 1
BR(config-subif)# exit
BR(config)# interface fastEthernet0.1
BR(config-subif)# encapsulation dot1q 1 native
BR(config-subif)# bridge group 1
BR(config)# interface fastEthernet0.10
BR(config-subif)# encapsulation dot1q 10
BR(config-subif)# bridge group 10
BR(config)# interface fastEthernet0.20
BR(config-subif)# encapsulation dot1q 20
BR(config-subif)# bridge group 20
BR(config-subif)# exit
BR(config)# interface dot11radio0

Wireless Bridge aironet 1410

We have a site with couple of consumer level bridged AP's. We have been recommended a Cisco 1410 wireless bridge but it is very expensive. What are the added features of this bridge and is someone using it? We originally were thinking of replacing the AP's with cisco 1231 AP's and bridging them as it would be cheaper.
Is there a benefit to using a 1410?

The Cisco Aironet 1400 Series Wireless Bridge is the premier high-speed, high-performance outdoor bridging solution for line-of-sight applications, providing features such as:
a) Support for both point-to-point or point-to-multipoint configurations
b) Industry leading range and throughput, supporting data rates up to 54 Mbps
c) Enhanced security mechanisms based on 802.11 and 802.11i standards
d) Ruggedized enclosure optimized for harsh outdoor environments with extended operating temperature range
e) Integrated or optional external antennas for flexibility in deployment
f) Designed specifically for ease-of-installation and operation
More information on the 1400 bridge is available in the data sheet at http://cisco.com/en/US/products/hw/wireless/ps5279/products_data_sheet09186a008018495c.html

1300 bridges

Can I associate the non-root bridge model 1310 to the root bridge model 1400? Is there any problems on the configuration I need to be aware of? I am really appreciated that.

I checked the product data sheet for the 1400, here is what they said:
The concept of mobile networks is significant not only for service providers looking to offer seamless network access, but also for individual organizations such as municipal public safety units. In many instances, the technology exists to create the zones that provide the mobile network, but the challenge lies in bringing the network to these zones. The Cisco Aironet 1400 Series Wireless Bridge provides a cost-effective solution to this application. The wireless bridge can connect to the network that contains the 2.4 GHz access points or bridges that are providing wireless zone coverage, and also provide the backhaul link to the high-speed network (Figure 2). Whether these zones are 802.11 hot spots at cafes and restaurants or bridged 802.11b cells for mobile networks, the Cisco Aironet 1400 Series Wireless Bridge provides a non-interfering and higher speed distribution service.

Can users directly access aeronets configured as Bridges?

Here is our scenario, We have two Aironet 1400's facing each other to extend our LAN btw two buildings
One is configured as root bridge the other is non root bridge. I see an option in the GUI to
configure as an Access Point. My question is- Does the fact that I have the aironets configured
as bridges prevent unauthorized clients from accessing the bridges and thus our network?
Are these bridges considered Access Points that a laptop can attach too?

Hi Richard,
If you do not want 802.11 clients on the bridge, leave the default Role in the Radio network value to bridge only mode. This allows only other bridges to communicate with the device.
From this excellent Q&A doc;
