LAP: Max no of client (Cisco 1252)

Is there any official documentation from Cisco that supports the below statement? Customer is looking for this information.
"There's no hard number that the AP can support. Cisco recommends no more than 25 clients per AP, but the AP will associate as many clients as possible without a restriction".
Thanks,
Colm

Here's an answer from Cisco PM J. Patil to a similar question (see Q.1 below). Hope it helps.

Re: ASK THE EXPERT - WIRELESS 11.N
Hi,
1. If you only have 802.11g clients, do you have more capacity for them if you use a 802.11n AP or you only can use this capacity with 802.11n clients? I mean can you connect more 802.11g clients in a 802.11n AP?
2. What is the difference between 4440 and 5500 WLC for deploying 802.11n? In the specs I've only found 802.11n is optimized for 5500. I want to buy a WLC for 30 AP's and I'm not sure waht is the best option for me. I'm afraid 4400 will be soon EoL announced since 5500 have versions for the same number of APs
Thanks

Jeevan> 802.11n AP similar to an 802.11a/g AP can technically have more than 100 clients connected to each radio at one point of time. However the experience that you receive will be diluted based on the applications that are being used, the bandwidth requirements and number of clients. The rule of thumb is that for enterprise-grade experience deploy upto 15 clients per radio or 30 clients per AP irrespective of 802.11n or 802.11a/g APs.
With the newer APs such as 1140 and 1250; there are significant advantages versus the older ones:
1.More memory(DRAM and Flash)
2. ClientLink technology enables higher downstream throughput to a/g clients
3. MRC technology enables higher upstream throughput from a/g/n clients

Jeevan> Similar to the AP evolution detailed above; the 5500 offers several benefits vs the 44xx:
1.      Ability to scale upto 250 APs with a software licensing model
2.      8 Gbps uplink
3.      DTLS encryption to ensure full-line-rate encryption between access points and controllers across remote WAN/LAN links.

1252 - Max Number of Clients

I have customer that is looking at deploying 1252 access points. I was wondering what the maximum number of clients that can associate to a single 1252. Does this count differ between 1252s running autonomous and LWAPP? The proposed configuration is using B/G radios at 54Mbps but quoting the A/B/G model for future 802.11n deployment (5Ghz radios would be turned off for now).
Any information would be greatly appreciated.
Thx
Joe

Its not as simple as the max number of clients but you also have to consider the type of client. Also food RF deisign and survey are critical to maximising client throughput.
There are rules for existing aps of approx 20-25 max for data. This would be 7 for voice in mixed mode b/g or 14 for g only and 20 for a only.
The ap can theoretically support many more clients, I think the figure is 256. With very simplistic data transfer such as bar code scanning I have seen as may as 50 clients with no issues.
As you ar lookig at abg these figures seem realistic.
With 802.11n you hav more bandwith available, better utilisation of the spectrum and therefore more client but its about being realistic and looking at what you are trying to connect.
Streaming multimedia would be lower than data only. Data only I would say 50 clients no issues but thats quite a density considering the RF footprint. For voice you are stuck with the above figures as you are still only dealing with abg clients.
Hope that helps

3x Cisco 1252 Wap Config/Scenario

Hi Everyone,
I have the chance to acquire quite a few Cisco 1252 LWAP's. I know it's possible to convert them to standalone AP's, so that's no issue.. Except maybe getting access to the IOS image?
Hoping I could use them in the following scenario. I work on special events & concert tours in large arenas & venues. I'd like to setup 3 of these units to work together to cover the venue. 1 at the back of the room where the audio console would normally be & the other two either side of the stage. There would only ever be 1 or 2 clients which are the tablets that control the audio systems DSP.
Is it possible to use them in standalone mode, all on the same SSID but on Ch 1, 6, 11? How does this work in the 'N' range?
We have a consistent issue that a single AP (older Cisco 1100) works fine with an empty arena, but stops working as soon as the room fills with people & there cell phones.
All your help would be greatly appreciated!

Cisco 1252 Access Point Read Write Account

HI
i sent out a Cisco 1252 AP to one of my sites and i removed the default cisco account from the device before i shipped it and now when i try to get into
it i can't .I can get logged in through telnet and it's working fine but i just can't get into the web interface. is there a way to re add the cisco account through command line so that i can log into it.
Thanks in advance

I tried that and it still dosen't work, do you think that i will need to just send them another AP fresh out the box with the account in it.

You need to set the power and the channel before you can enable the 40mhz channel width.
Use one of these for above 40mhz:

Cisco 1252s with regular 802.3af PoE switches - what are the impacts?

Does anyone have any real-life experience with deploying the 1252s on regular 802.3af PoE switches? I have a few 1252s one some 3560 PoE ports and the show up with "low power" alarms.
I am wondering what the real world impact is with this scenario. The 1252s have both 2.4 Ghz and 5.0 Ghz radios in them and I have HT enabled on the controller.
I'm wondering what capabilities I am losing by running on 802.3af power besides the annoyance of the alarms.
Thanks in advance!

Sorry in advance for the book I have just written.
I have three 1252s on 75 feet of Cat5e cable running to a 3560 PoE switch. Sometimes, but not always, I see a low power alarm on the access point(s). This is in a small building that is built like a fortress so the RF environment is somewhat challenging. I am watching WCS closely and see all three 2.4 GHz radios powered all the way up to power level 1. I notice that two of the 5GHz radios are on power level 1, and one is on level 3. I thought that RRM would not power anything down until you had at least four access points as RF neighbors. I believe I read that in a Ciscopress book and it seems to be true everywhere in our network when I look at buildings with 3 or less WAPs.
The building in question does not have any other buildings close by with any 5GHz radios in operation - or at least I didn't see any when I did the survey.
I'm wondering if the power setting of the radios is also related to the length of the Cat5e cabling. Seems to me a shorter run would have less resistance than longer runs, allowing the radio to have more power.
My main concern is not this building in question, since we went for coverage and not client density in the design. We several other buildings on the radar, all libraries, which are going to be both RF challenging (bookshelves, furniture, cubicles, cubbies) and client-density challenged. These buildings have hundreds of WLAN clients in them at times - and I mean devices, not just people.
Someone else told me (reputable source) that channel bonding is not an option when on 802.3af power. Makes sense, actually. I would never even think of bonding in the 2.4 GHz range for obvious reasons, but up in the 5GHz range it is a definate possibility in these buildings. Seems to be that we might be shooting ourselves in the foot by not using 802.3at power in these buildings.
If channel bonding is disabled and the upper two MCS rates (using 800ns guard interval) of 117 and 130 are disabled, then I'm looking at maximum MCS rate of 104 Mbit/s compared to 270 Mbit/s with 802.3at with channels bonded in the 5GHz range.

PoE auto switchover with Cisco 1252 Access Point.

Dear All
I have a network for Managed Wireless using Cisco. This is a new network for me.
I am in problem with Cisco Access Point 1252. My AP's are connected to a PoE Switch. And Cisco AP's are also connected Powered with also Power Adapter with UPS backup.
But problem is if I disconnect power source of AP Power Adapter , AP is not getting up with PoE. PoE is up only when POWER PLUG of AP ADAPTER is physically pulled out from Socket.
Question is if it is possible to make automatic Failover by PoE when Power source of AP ADAPTER is down ?? I mean no need to PULL OUT POWER PLUG of AP ADAPTER.
Waiting for your rely.
It is very urgent .
Thanking You
Subrun.

Hi Suburn,
1- yes it is possible to do failover without unlupping the cable of AC adapter. When power on ACS adapter is off, then the faiolver happens.
2- with regards to POE, if your switch supporting enhanced POE?

Max number of clients on 1242 LWAP?

I have a local mode 1242 LWAP that gets dragged around from city to city as a mobile WLAN-in-a-Can. So far it phones home and re-joins it's WiSM properly. In actual use no more than six laptops can connect and that's the problem.
I set the globally controlled radio profile for clients from 12 to 15 but that doesn't seem to help.
Is there something else I can check or am missing?
WiSM 6.0.196.0
WLAN WPA/PSK/TKIP 2.4Ghz only.
Thanks!

Hello,
please check the client load balancing , is it enabled?
you need to check it globally , from wireless ->> advanced ->> load balancing

How To join Max OS C Clients to a Linux Samba PDC

Hi,
we do have a working Linux Samba PDC for a lot of Windows XP Clients. Now, we'd like to join the fewer Mac OS X Clients also to the PDC, so that users can login to the hopefully same profile/home directory from PC and Mac.
Is this possible? If not, is it possible to only authenticate the Mac OS X Users against the samba pdc (without automounting shares ...)?
Are there any How To?
Thanks for any hint and suggestion! Best regards.
Götz Reinicke

Hi Luis,
You also need to add the Linux user to samba using the smbpasswd -a username command, aslo the machine you are accessing needs to be added to the smbpasswd file using the -m (this can be run only by root)
for more details on the command do a
man smbpasswd.
Hope this helps.
Thanks.
