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?
>> A lot.. here is the details..

http://www.cisco.com/en/US/netsol/ns621/index.html
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.

Help required to implement Cisco 2504 WLC and 1042 Access Points

Hi,
My name is Vidya Sagar. I am new to Wireless technology. We are planning to implement Wireless in our office. I have given the requirements below. Kindly go through the details and let me know how to start.
We have purchased Cisco 2504 Wireless Controller (One) and Ciscon 1042 Access Points (Five). At present I am going to use 3 access points only.
I have attached a simple diagram of our office network. We have more than 30 VLANs configured in Core Switch, we are planning to give wifi access to only 3 VLANs.
1. VLAN 121 ( IP Segment - 10.52.121.0 /24)
2. VLAN 116 ( IP Segment - 10.52.116.0 /24)
3. VLAN 100 ( IP Segment - 192.168.100.0 /24) (Guest)
Please give me a implementation plan to do this. I would like to use LDAP or ACS for authentication purpose.
Regards,
Vidya Sagar

Lets just do this simple first before you start using ACS as that will require a certificate installed on the ACS for using PEAP.
So first off, the WLC we will say is in vlan 10. When you are going through the startup wizard, make sure you define the vlan tag to 10 on the management interface. Make sure your virtual interface is an IP address that is not routed in your network, like an out of band IP.
Make sure the WLC time is correct or use NTP!!!!
Now you should be able to http or https to the WLC. I would upgrade the code to v7.4 and install the FUS image. Please reference this link for the upgrade procedure. You don't have to upgrade now... I would wait till you get everything working first.
http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn74.html
Now I would connect the APs on the same vlan as the WLC for now. Make sure there is dhcp on that subnet. Once the APs have joined, then you can move them to any subnet you want. Since you don't have many APs it would be okay to leave them in the same vlan as the WLC management or out them on any other vlan you choose. The APs will be connected to an access port NOT a trunk port!!!!
The WLC will need to be connected on a dot1q trunk port only allowing vlans 10,100,116,121. The 2504 running v7.4 will support LAG (etherchannel). Any ways, your switch port should look like this for example only
Interface gigabit1/0/1
description WLC2504
switch port trunk encapsulation dot1q
switchoort mode trunk
switch trunk allowed vlans 10,100,116,121
spanning-tree portfast trunk
channel-mode group 10 mode on << only for v7.4 if you use lag
Don't connect all four ports right now, just port one!!!!
Your Guest vlan, you will need to create an ACL to block traffic from accessing the internal network. You might want to allow dhcp and DNS bit I would leave it open first until you can verify everything is working.
Now on the WLC you need to create a dynamic interface for vlan 100, 116, and 121. If you click on the Controller tab in the GUI and click on interfaces on the left hand side, that will take you to where you can add/delete/modify your interfaces. When creating these interfaces, make sure you add the dhcp server IP address for the primary and or backup.
Now that you have your dynamic interfaces created, its time I create your SSID. Now click on the WLAN tab on the GUI and click on WLAN and then on the too right select Create New and then click go. Select WLAN on the drop down menu and then for the profile name I would use the SSID name also for simplicity.lean e the WLAN id to 1 for this and 2 for the next and so on. After defining these and clicking Apply you can now define your SSID. On the General tab, enable the status and leave the radio policy to all for now, you can decide later what you want to use. Choose your interface you wan to place this SSID on and enable Broadcast SSID for now and leave everything else alone. Now click on the Security tab and on the layer 2 Security, leave it at WPA + WPA2, only check WPA2 Policy and for WPA2 encryption choose AES only. Now go to the bottom of that screen and choose PSk. We will do pre shared key for now so you get to understand the setup and make sure everything is working first. Now on the PSK format, choose ASCII and put your pre shared key in the input box. Make this simple to for testing. You don't want to put in symbols or anything like that. When you are don with that, check apply on the top right and test.
Now you can repeat this with your other SSIDs just to test. Your guest network you can leave open for now to test open authentication.

Trunk with WLC and 1400BR problem

hi everybody,
i have the next proble, i hope someone can help me
Actually I wrok with a 1522 Mesh Network,1130 LWAPP and Bridge 1400 point to point. 1522 and 1130 are asociated with WLC.
I have a WLC4402 (4.1.192.22M (Mesh)image) this wlc is conected via trunk to Sw3750 ex:
interface GigabitEthernet1/0/1
switchport trunk encapsulation dot1q
switchport mode trunk
RAP1 is connected to the sameSw3750 ex:
interface FastEthernet1/0/23
description RAP1
switchport access vlan 10
**(VLAN 10 is Mgmt)**
AP1(1130) is connected to the same Sw3750 ex:
interface FastEthernet1/0/1
description AP1
switchport access vlan 10
The 1410BR Root is connected via trunk to same Sw3750 ex:
interface FastEthernet1/0/19
description BR-1400R
switchport trunk encapsulation dot1q
switchport trunk native vlan 10
switchport mode trunk
In the other point is the Non-Root connected to a Sw2960 ex:
interface GigabitEthernet1/0/1
switchport trunk native vlan 10
switchport mode trunk
AP2(1130) connected to the same Sw2960 ex:
interface fa0/23
descriptipon AP2
switchport access vlan 10
The network is work fine, Mesh UP (RAP and MAPs), and 1130 too.I connected the 1400 Bridge point after the Mesh is up, and the link between Root and Non Root is UP
Now, when the Sw3750 goes down or reboot,the RAP and AP1(1130) can't associated to WLC. The ports of RAP and 1130 are down and up many times, so can't associated to a WLC. Only the Bridge point 1400 Root and Non-root are UP, and the AP2(1130) in the other side can associated to the WLC.
When shutdown the port of the Root Bridge, Now the RAP1 and AP1(1130) can associated to the WLC and the Mesh Net is UP. Then no shutdown the Root Bridge port and the link between Bridges are UP, AP2(1130) up to the controller too.
But after several minutes the Bridge down, and the event log in the Root is:Interface Dot11Radio0 Radio transmit power out of range.
So i have this problems
1) Trunks between WLC and 1400 BR
2) Bridge conectivity range.
Regards
Antonio

The Outdoor Bridge Range Calculation Utility uses parameters that include regulatory domain, device type, data rate, antenna gain, and a few others as inputs.
You can avoid connectivity problems with the Outdoor Bridge Calculation Utility, as this tool helps you to predict the distance between devices. In a wireless environment without a tool like this, you cannot predict the distance between the bridges, the height at which you must place the antennas for maximum throughput, and other variables. This utility also helps you decide on the type of antenna that you must use in order to cover the distance between the bridges.

WLC code for point to point bridging

What is the best WLC code for point to point and point to multipoint bridging on a 2504 with 2602 APs? 7.2-7.4 had transparent vlan issues and I'm not sure if they were fixed in 7.5-7.6. We have 5-6 vlans that we are needing to bridge between a large open area. Also, are there any bugs with wireless mesh and ISE?

You do not have many choices now, only 7.0.250.0, 7.4.121.0 & 7.6.110.0 codes are supported by Cisco. All other codes have been deferred by them.
I do not have configured those set-up to advise you specific to that. I would think 7.6.110.0 may have fixed whatever the known bugs in previous versions.

Looks to be wither a duplicate address issue or a configuration issue. Try to test with only using the 2.4ghz and then again with only the 5ghz and see if you see a difference.

3502p AccessPoint support MESH and Point-to-Point Wireless Bridging with Outdoor Antennas??

I need to know if 3502p with outdoor antennas supports Point-to-Point Wireless Bridging??

The 3502p is only used for arenas and or stadiums. These are different units than the 3500's and 3600's. So no they can't be.
You can use Cisco Aironet 1400 Series Wireless Bridge for a wireless link between two buildings (1km) to extend your LAN. For more detail you can go through the below link.

Create a point to point link with a wlc 4402

Hi to all,
i have a wlc 4402 and i need to configure a point to point link with two air-lap1310g-e-k9, i have found on cisco.com this link:
http://www.cisco.com/en/US/products/ps6366/products_configuration_example09186a00808e9c1b.shtml#zero
but on the wlc configuration page i cannot found some configuration step.
Someone have configured this type of behaviour or can give me some hints?!
How can i configure on the wlc the parameter about the bridges configuration?! Or i must configure the bridges overriding the global configuration?!
Thanks and best regards,
Carlo Sagratella.

The correct thing to do would be to downgrade the 1310's to autonomous (or 1242's) and set up a root bridge and non-root bridge.
Alternately however, if you REALLY wanted one of the points to be LWAPP, in theory you could always make one of the Access Points Autonomous and join it as a workgroup bridge to the LWAPP AP. However, there really is no reason to do that since it would be cleaner to convert both to autonomous.

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?

Bridge Point to Point with AP 1552EU - Maximun Data Rate

Hi all, I have a question for you, and I need your help.!!!
I have two site (Central and Remote) and I did a link point to point between it. These AP are managed by a WLC 5508, the distance between this AP is 30 Mts or 98 feed, I have configured the channel width in 40Mhz in the WLC, and MCS-5 in the data rate sección of Bridge AP. I did tests flooding the link and I only can transfer 40Mbps in both directions at the same time. This ap model is 802.11n capable. So how can I increase the data rate from 40Mbps to 100 o more Mbps.?
The antennas are directional with two ports (TX/RX) and are connected in the ports 1 and 3 of AP.
I hope your response.
Thanks,

Wow. You're radios are only 100 feet apart and you have 14dBi directional panels hooked up to them? Hopefully the TX power is configured properly and is turned *way* down.
You should certainly be able to get 802.11n HT rates between two 1550s with these antennas and 2 spatial streams. You *should* be able to achieve HT MCS 15 at 40MHz with a PHY data rate of 300 Mbps. Actual Layer 3 throughput would be approaching 100Mbps, but I think you are more likely to see ~80Mbps in actuality.
Best of luck!

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.

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

Air Bridge 1310 - Configuring QOS on Point to Point

I have 2 BR1310 Air Bridge's configured for a point to point connection, one is root,one is non-root. In configuring QOS for VOIP for the first time, I'm looking for a best practice configuration.
Behind each bridge is a 3560 switch that has QOS configured on each switchport. Our environment consists of 7960 desk phones.

Hi Michael,
Have a look at these docs. Hopefully they will help get you started;
Cisco Aironet 1300 Series Outdoor Access Point/Bridge Software Configuration Guide, 12.3(4) JA
Chapter 14 - Configuring QoS
This chapter describes how to configure quality of service (QoS) on your access point/bridge. With this feature, you can provide preferential treatment to certain traffic at the expense of others. Without QoS, the access point/bridge offers best-effort service to each packet, regardless of the packet contents or size. It sends the packets without any assurance of reliability, delay bounds, or throughput.
From this doc;
http://www.cisco.com/en/US/docs/wireless/access_point/1300/12.3_4_JA/configuration/guide/o13qos.html
Giving Priority to Voice Traffic
This section demonstrates how you can apply a QoS policy to your wireless network's voice VLAN to give priority to wireless phone traffic.
In this example, the network administrator creates a policy named voice_policy that applies voice class of service to traffic from Spectralink phones (protocol 119 packets). The user applies the voice_policy to the incoming and outgoing radio ports and to the outgoing Ethernet port for VLAN 77.
Use the Apply Policies to Interface/VLANs drop-down menus to apply policies to the access point Ethernet and radio ports. If VLANs are configured on the access point, drop-down menus for each VLANs' virtual ports appear in this section. If VLANs are not configured on the access point, drop-down menus for each interface appear.
From this doc;

Hope this helps!

Point to point wireless using 1310 and 1231 on each site

Hi,
I have an implementation right now with wireless point to point bridging connection. I installed a 1310 with 24 dBi external antenna on one site and a 1231 AP/bridge with 24 dBi antenna on the other site. Has anyone of you tried this set-up. I have no problem with the connection and pinging is ok. However when I tested the throughput I only got 2Mbps in which the distance between the two sites is only 2 kms. I am hoping to have a throughput about 20 Mbps and up.

When you configure the AP radio, you must consider the type of clients that are present in the wireless network. If the AP has an 802.11g radio and the WLAN has only 802.11g clients, you can set one or more data rates to Basic and all other data rates to Enabled However, if you have a mixed environment of both 802.11b and 802.11g clients in a WLAN network, you must ensure that only the rates that 802.11b supports are set to Basic (or Require in GUI). If data rates that the 802.11b radio does not support (such as 12 Mbps) are set to Basic on the AP radio, the 802.11b clients are not able to associate to the AP.
Alternatively, you can configure the AP radio to select data rates on the basis of range or throughput. When you configure the AP radio to select data rates for range, the AP sets the lowest data rate to Basic and the other rates to Enabled. In this way, the AP can cover a wider area. However, the data rate comes down as the distance from the AP to the client increases. If you configure the AP radio for throughput, the AP sets all data rates to Basic. This configuration ensures a consistent throughput throughout the coverage area.

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

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.
