Mesh design

hy engineers
My question is this desire to deploy a wireless network through mesh, but the locationof the access point for this purpose is behind the walls, I want to know if a design formy mesh access point must be linear or serial, or must see each other, or there may be some interference, such as walls, ceilings or something else.
1. Must have line of sight between the access point for mesh or there may be interferencefrom walls or other materials?
2. The 1310 access point or work against a parent should be autonomous?
3. What percentage of overlap should be in the access point should make a mesh topology?
4. There are access points that handle ny protocol can be implemented for mesh?
thanks for your help.

Mesh design question

Dear Sirs.
My customer plans to extend existing wireless coverage and upgrade to controller based network.
Let me shortly describe the situation based on the attached network map.
RAP points are installed on the buildings, they have wired uplink.
MAP points are installed outdoors (in the IP66 sealed ABB boxes) on the poles (height 5 m), only power is present on the poles, no wired uplink.
Now MAPs (Non root bridges) are connected to RAPs (Root bridges) via 5 GHz interface in bridge mode.
Red points: already installed Autonomous APs, 1242AG model.
Green points: APs planned for installation.
1. In order to upgrage to controller base network I want to install two 2504-25 controllers in failover mode. I have AP-to-LWAPP-Upgrade-Tool and is familiar with the image upgrade procedure. However, I have a question: if I upgrade all existing RAPs and MAPs to LWAPP mode, how the MAPs without wired uplinks will connect to RAPs and then to controller? Should I have physical access to their console port to issue some CLI commands to connect to RAPs?
2. Can 2504 controller be configured for operation in mesh network mode without additional licenses?
3. For network expansion I plan to install 3502E access points in sealed boxes. I chose them due to separate 2.4 and 5 GHz antenna ports, in order to use omni antennas for 2.4 client coverage and 5 GHz directional antennas for wireless uplinks. The distance between APs is abou 100 - 250 meters. Is it recomended to use directional antennas for wireless uplinks or I can take 1602E (or 2602E) access points and dual band omni antennas and install a good working mesh network with 5 GHz uplinks on omni antennas?
4. Can 2504 controller work together with 1242AG, 1602E and 3502E points?
5. How should MAPs be preconfigured to begin working in mesh network after powering them up on the poles on site?

> The MESH AP's along with your other access points (lightweight) will obtain their code from the WLC when they join. I would always stage the MESH AP's prior to mounting them to certify they work and they can form a link. You would need to purchase a power injectors for each RAP and get a AC power adapter for each MAP.
The Upgrade tool is to only convert autonomous AP's to lightweight. They stopped supporting 802.11n access points in that tool.
2. Can 2504 controller be configured for operation in mesh network mode without additional licenses?
> With the newer code version you will be using, yes. You can have both MESH and traditional Local mode or FlexConnect mode access points.
3. For network expansion I plan to install 3502E access points in sealed boxes.

> If these are going to be exposed to the outdoor elements, then you need an outdoor antenna. It's hard to say what antenna you need, but if your using a 3502e, make sure you get an antenna that is a 3 lead so you can utilize all 3 antenna ports. Patches are directional, so if you are going MAP to MAP to MAP to RAP for example, you would need an omni. Patch works if your going Fromm MAP to RAP.
4. Can 2504 controller work together with 1242AG, 1602E and 3502E points?
> Yes they can. The code you run in the WLC, you need to make sure it's supported by the access points. Here is a compatibility matrix

5. How should MAPs be preconfigured to begin working in mesh network after powering them up on the poles on site?

Mesh Design Question -- Guest Access

In reviewing all the documents concerning Mesh with the controllers and Guest access. I'm assuming the following, through a redirect on the WLAN controller we can have a guest client create an account and also have their credit card charged. We are getting ready to building an 80 radio 1522 mesh network using the 4400 WLC. Do we need the WCS program or is that over kill? And is my assumption on the guest portion correct?
Thanks

Although I have never tested this credit card stuff with the WLAN, however note that WCS is an optional software for extra managability (with some really good feauters). It is not required to run the WLAN setup.
A tip for ur design of 80 radio network: while using 1522 mesh APs, you dont need a controller with a capacity of 80 APs. Actually you need lesser capacity. In design phase, while calculating WLC capacity, count RAPs as 1 and MAPs as 1/2. for example if you have 10 out of 80 APs as RAPs in ur design and remaining 70 as MAPs you actually need a controller with a capacity of (10x1)+(70x1/2)=45. so 4402 with 50 AP capacity will do the job.
Please feel free to contact me if you wish any further discussion.

Ten 1142N APs and one 2112 Controller MESH Design. Is it possible?

Hi all.
I've came with this question when started wireless design, so will appreciate any help. I want to implement MESH Wireless Design.
There are 3 floor building. One controller connected to one RAP configured AP on each floor by Cat5 cable, so 3 RAPs. Other APs on the floor are configured as MAPs and connected to RAP wirelessly.
The simple diagram:
AP5 AP4 AP3 AP2 RAP1-----Cat5-------Controller 2112 ---Cat5----- DSL Router---Cat5-----Internet
I can't use Cat5 cable to all APs, as there are 3 floor building, with max distances over 300 metres.
The question is:
Can these devices be configured for MESH topology?
I followed that article from cisco website.
Cisco Mesh Access Points, Design and Deployment Guide, Release 7.0.116.0
Is there any other solutions, wirelessly connect controller and 10 APs?
As I thought it can be connected wirelessly, that's a purpose of the controller. But some sellers and technicians say that every AP should be Cat5 connected.
Thanks in advance.

I have a similar situation. I have to setup a temporary WLAN solution to handle appx. 400 clients for a 1 day event. I have extremely little time to get this together, such as a couple days, as I said, very impromptu project. I have a WLC 5508 as well as several 1142n LAPs at my disposal. I believe the 1142n can operate as a mesh AP correct? Problem is, where the WLAN and internet is needed, there is no existing infrastructure, I'm aiming to extend our infrastructure there wirelessly. I plan on deploying the 5508 at our location where we do have some infrastructure, setup 2 LAPs as mesh APs, with the root being at same site as WLC. Then extend the network via the mesh APs to the new site. I'll be using a Catalyst 3560-24 PoE at the new site to both power up the APs as well as provide local switching. Then create a new WLAN/SSID for the new site and enable that for necessary access, intent etc.
Does this sound as if it would be a feasible solution for a "quick and dirty" temporary wireless solution? Also, how many LAPs would you recommend to handle appx 400 400 clients? I believe each of those LAPs can handle appx. 25 clients with a max of 50? I don't expect 400 clients to be actively using the system, but in attendance. I just have to ensure that if they opt to connect, they can. Obviously I want adequate performance, but max performance as far as bandwidth is not necessary here, instead maximum connections.
If anyone has any suggestions, I certainly welcome them. Once again, thanks in advance. If I can help by supplying additional information I'll be happy to. Thanks again.

Outdoor Wireless Mesh Design Question

Hi,
We have a wireless mesh network which currently is having some connectivity issues.
One of the main issues we are seeing is with RRM configured the Mesh Access points seem to all select Channel 11 on the 2.4ghz frequency.
I would ike to modify manually, although wondering if best practice is to use RRM or select manually.
Thanks
Brad

Hello Bradley,
We'll, if you have WCS then a mismatch would happen with the cnofig template on WCS (if you have one).
There could possibly be an AP template on the WCS to set the radio for the APs automatically.
This is from Configure -> AP Configuration Templates -> Lightwieght AP.
From this location you can configure a template with the AP settings and push it to the APs you want. You can also schedule the time at which the template will be applied. A recurrence also can be configured.
So make sure that:
- No mismatch between WCS and WLCS (you can go to Configure -> Controllers and try to audit differences between WLC and WCS).
- Save your configuraiton on WLC if you apply it from WLC.
- Make sure that there are no AP templates on WCS with recurrence configured.
To avoide any mismatch in the future, I suggest you do all your configuration from WCS. This way you'll save time (if you have more than one WLC) and you'll also make sure configuration is consistent among all controllers.

Large amount of traffic with 152x mesh and mac-flap

We have just had a Mesh designed by an external company, and when we plugged it in we began have large numbers of mac-flap notification and more than 700mb of traffic sent across our data network.
Our setup includes 2 5508 controllers and 9 152x APs
3 APs (RAP) with their 5.8 antennas are within close proximity on a vertical pole pointing to the other 6 about 1000mtrs away in an arc. With their ethernet ports plugged into the same switch (native vlan 111) as WLC1 (which is LAG'd to two ports)
Vlan 111 for management of Mesh
Vlan 201 for WLAN
DHCP scope on DC on Vlan 100 (helper address from router)
Q, will the closeness of the 5.8 antennas cause any problems with mac-flap or is likely to be the controllers with their LAG connections or something totally different?
Thanks for any help

Andrew,
the proximity of the antennas shouldn't cause the mac-flap notification, nor should the LAG connection cause this. That's more and indication that the client is flopping between ports on the switch, which generally happens when you are not configured for LAG on the WLC, nor a port-channel on the switch.
the mac address that is being reported in the mac-flap. Is it a client or is it the MAPs?
If it's one of hte MAPs, you may want to check the antennas of the RAPs, since the MAPs sholdl stabliaze once AWPP has run and optimized the path to the network. If they are flapping I would look at possible RF or antenna issues.
HTH,
Steve

Outdoor wireless mesh deployment for major events

I am interested to hear if anyone here has any experience in setting up a large scale wireless mesh deployment that covers an area that are a few blocks.
1. How do you deal with 2.4ghz interference as 2.4ghz and 5ghz band are unregulated. I'm not able to use 5ghz as the end devices are smartphones that do not support 5ghz.
2. How do you deal with the backhaul capacity as each hop for Cisco Wireless Mesh would result in a 50% drop in network throughput.
3. How do you deal with installation of the wireless mesh APs in public areas. Do you install this on a mast and leverage on the lamp post to provide power? Or do you talk to building owners to install the APs on the top of buildings? What are the challenges you face in installing wireless mesh APs in a public area.

Hi David,
Here is some info that might help.

Mesh AP 1524SB SOS :)

My quiestion is about wirelees ap1524SB. Can this product operate in a full mesh topology network or it is just suitable for a linear(serial) interconnecting of the mesh access points? Can I build a mesh network based on ap1524 only? What topology can I use? Thanks in advance.

There are a fair number of design considerations to address in a mesh network. Perhaps the document below will help?

Cisco AIR-LAP 1522 PROBLEM

Hello to everyone. They brought me a LAP1522 referring that it is not working properly. I am trying to connect to console port but the problem is that I only get log messages but I cannot edit something or type any commands. I have attached the log messages if you can catch something from there. Ignore the messages about not finding controller because the AP has been removed from the real network to my office.

The access point has a reset button located on the bottom of the unit (see Figure 3). The reset button is recessed in a small hole that is sealed with a screw and a rubber gasket. The reset button is used to perform these functions:
•Reset the access point—press the reset button for less than 10 seconds. LEDs turn off during the reset and then reactivate when the reset is complete.
•Disable battery backup power—Press the reset button for more than 10 seconds. LEDs turn off, then on, and then stay off.
–You can also disable the battery remotely by entering this command:
config mesh battery-state disable AP_name
•Switch off LEDS—Press the reset button for more than 10 seconds. LEDs turn off, then on, and then stay off.

LAP 1522, 5Ghz interface not working

Hi,
I have some problem with one access point LAP1522.
The LAP1522 operate in a mesh network and the role of LAP1522 is MAP.
LAP1522 worked well until a few days ago.
I do not know the reasons for wich the LAP1522 does not register to WLC on the radio interface (5GHZ).
This is the message on the console port :
*Mar 1 00:22:36.031: %CAPWAP-3-EVENTLOG: CAPWAP state not up. Abort
sending channel and power levels info.0:0:0:0
*Mar 1 00:22:36.039: %CAPWAP-3-EVENTLOG: CAPWAP state not up. Abort
sending channel and power levels info.0:0:0:0
*Mar 1 00:22:38.055: %CAPWAP-3-EVENTLOG: CAPWAP state not up. Abort
sending channel and power levels info.0:0:0:0
Why the LAP1522 can not connect to WLC using radio interface ?
If i connect the ethernet port on LAP1522 to switch, the AP register to WLC
5508.
Thanks.

Cisco 1500 series AP. Coverage distance

Hi everyone,
I'm looking into a project to cover a large residential area with wifi using the 1500 series access points on 2.4Ghz and using a 5Ghz backhaul.
Before I go ahead an organise a site survey I'm trying to get a rough idea of the coverage distance on the access points when used with standard dipole anntenas.
They will be mounted onto street lights and in clear line of sight of the next mesh point. access speeds from 1Mb upto 11Mb will be needed by client devices.
I know this is a best guess question but If any of you have experience in this environment your assistance and input will be greatly appreciated.
Thanks
Arron.

DMVPN and NAT

Hi All,
I am trying out a simulation on my own at the moment to try figure out if it is possible for a Router at a branch office running DMVPN to have a NAT setting such that if anyone accesses this NAT, it will be directed to a server at the HQ office.
Here is the full picture. I have multiple spokes in my DMVPN design with a single Hub. All spokes are able to access each other so this is a full mesh design. Each routers have their own Internet access so I would have a NAT Overload rule. In the real world, two of the spokes (SPOKE A & B) needs to route via one of these spoke (SPOKE C) in order to reach the hub because latency-wise, it is way better than going direct. Because the management now wants to build more web services but allow Internet users to access via one of the the remote spokes at SPOKE A & B. Sounds easy if i create a static NAT but if I create a static NAT rule at one of the remote spokes, the return traffic will be asymmetric. Problem is that every routers will have their own Internet access, by the time the return traffic heads back, the hub router would have already routed out via its own Internet because the source IP is public.
Is there anyway that we can configure the NAT rule on the remote spokes so that it will also do a source NAT together with a destination NAT so that the return traffic will return to where it originated from (the remote spoke which has the static NAT)? Or is there any alternative solution? I don't mind hearing the pro and cons.
Thanks in advance!

Desmond,
I hope I'm understanding the problem :-)
Mind that I'm talking about concepts here, I think technically those will work, but it's not something I've tested.
Re. idea 1)
When I was suggesting reverse proxy I was not suggesting WCCP, although it would be cool :-)
NAT + Squid would be sufficent.
I.e.
Say the real sever IP is A.
Squid's private IP address is B.
Squid's public IP is C.
What I had it mind is that when connecting on spoke X, everyone would be using IP address of C (from outside/DMVPN).
That would be statically translated to B.
Now B would go to A (real or private) to get to the actual content (you can also implment cache'ing on squid to further optimize the link utilization).
A replies to B, B replies to whoever contacted them over internet (by going out through NAT).
Re. idea 2
Switching to NVI NAT could be an idea, you don't have to specify "inside" and "outside".

WLC 4404-100 with CAP1550E

Currently I have a WLC 4404-100 and 96 nos. LWAP 1250 installed at site. I need to add CAP1550E (4 Nos.) to this existing setup. Out of this CAP1550E, 2 needs to be configured as root, and the remaining 2 has to be connected through 802.11a/n backhaul and meshed.
Can I achieve this scenario, without adding a new controller??
Thanks to all in advance.....

jerrick,
Yes you can. Mesh and non-mesh functionality has been merged for quite some time now. Use more recent code (7.0.x) or higher for best results.
If you are unfamiliar with configuring mesh, consider spending some time scanning the 7.2 mesh design guide. Mesh works a little bit differently than your traditional local-mode APs and you need to do some additional configuration on the controller to tune it to your environment.
7.2 Mesh Design Guide: http://www.cisco.com/en/US/docs/wireless/technology/mesh/7.2/design/guide/MeshAP_72.html
One thing the guide doesn’t say (I don’t think): Get it working on the ground first, then hang your APs. It will save you a lot of time and frustration.

CAPWAP vs LWAPP

Hello all. I have WLC 4402 and Aironet 1522 AP's. Implementation includes mesh topology and ethernet bridging. I have configured LWAPP L2 in the very beginning. But then I have read that for ethernet bridging LWAPP L3 must be configured. Till now mesh is working fine, but AP that provides ethernet bridging some times goes down. Few minutes ago I have found this http://www.cisco.com/en/US/docs/wireless/technology/mesh/design/guide/MeshAP_52.html#wp1167834 where it says that in release 5.2 (and that release is on my WLC) CAPWAP replaces LWAPP.
So, what should I do?
Should I configure for ethernet bridging LWAPP L3 or what?
Thanks in advance!

Although CAPWAP is based on LWAPP there are some critical differences to note. First, control traffic is no longer contained in a AES encrpted LWAPP tunnel and data traffic in the clear. On a WLC 4400 data traffic is still in the clear and control traffic is in a DTLS encrypted tunnel. In the upcoming controllers it is proposed to enhance security by including ALL traffic in the DTLS tunnel. Second, the CAPWAP discovery process is much more robust than LWAPP. Third, dynamic MTU is part of CAPWAP. This allows for better communication between the controller and the network. This was a big issue with LWAPP and a much needed improvement.
Layer 3 is the ONLY method I would deploy in either LWAPP or CAPWAP as it truly enables the functionality of IP. I was a big proponent early on of Layer 2 for small offices but as IP Voice communications and applications continued to develope, the need for Layer 3 in all deployments became more evident. This became Cisco's plan as well and layer 2 is considered a out of date legacy method of configuring a WLAN.
