H-REAP vs Local mode on LAN with a single WLC

Hi
I have a question about H-REAP vs Local mode on a LAN with a single WLC.
We use EAP-TLS with Cisco ACS for authentication of wireless clients.
Up and until controller version 4.2 it was not possible to authenticate using 802.1x when a H-REAP AP went into standalone mode.
Code above 4.2 can now support this. According to the documentation all you need to do is configure the RADIUS IP addresses on the H-REAP AP.
Usually I would use H-REAP with central authentication and local switching for AP’s that are separated from the WLC via a WAN link.
However, a colleague has suggested that we could configure H-REAP (central authentication\local switching) AP’s at the same site as the controller. This would give us the advantage that if we lost the controller (we only have 1) then at least the AP’s could still authenticate users.
I am trying to see the “cons” of this solution. I guess roaming would be affected when the AP’s went to standalone mode as each roam would require complete re-authentication. But this is still better that a hard down state. Are there any cons to this approach during normal operation (e.g. when the controller is up)?
What about RRM limitations?
I seem to recall that a H-REAP AP was unable to increase its power output to address coverage holes?
Layer 3 roaming not supported on locally switched WLAN’s?
I would appreciate any thoughts\feedback
Thanks,
Andy

My 2 cents :
-I don't recall the HREAP APs having any RRM limitations in recent code.
-No layer 3 roaming when you are locally switching. If the APs are dropping traffic locally at their switchport, you can't tunnel through WLCs like it happens when you usually do l3 roaming.
-There are a number of features not supported when you do H-REAP. WGB is one of them for example. Fancy features like directstream and others.
-The best answer in your case would be to have a second WLC where the APs can failover to. But I know it's not always possible.

Can Local Mode Cisco Mesh APs (1522/1552) be supported in a Multiple country code 5508 WLC?

I've read previous discussions (i.e., "wlc 5508 multiple country codes + mesh ap") on this forum that stated Mesh APs can't be supported on a WLC set-up with more than one country code configured. If you have Outdoor APs which are set-up for local mode only, and not used in a Mesh wireless architecture (using Mesh Beacons), will this apply as well? I don't know if there are any caveats to this. Or if Cisco 1522/1552 APs can't be supported on a WLC using more than one country code period, regardless for how they are used, since they are considered Mesh APs. Another question, can a WLC support two regions (Region E and Region A), in a two country code assignment? I've read on the forum the downfalls for using more than one country code on a WLC, so understand that it will use the lowest common denominator settings (i.e., power, channels) for operation, so this isn't ideal.
I want to stick to one controller using one country code only. This isn't something I want to do, but we had an issue with an order being processed for APs, which resulted in the wrong region APs being delivered by a vendor, and leadership is exploring alternative options. So, the above is worst case scenario planning if we can't swap the APs back for some legal reason, or if it takes too long to accomplish. We could always purchase a smaller WLC with a license size to support only the different region APs purchased if it comes to it.

Hi,
As per my experience, Normal APs(Local Mode) can work with multiple Country Code .
WLC can support multiple country code but it's a bad idea to have it. Only common channel, power will allowed.
Best is to buy a 2504WLC and use it.

Slow report viewer/rdlc performance in local mode with Single Sign On

Hi Team,
We have recently enabled Single Sign On to our application and after that our rdlc reports loading got extremely slow.
Please find the below configuration that we are using.
1. Report Viewer 11.0.0.0
2. running rdlc file in local mode (not using Report Server)
3. System.IdentityModel.Services 4.0.0.0
The query behind the reports is returning result in 5-10 sec but report is taking 1-4 min to load (sometimes getting timeout) (as per the complexity of the report).
We have tried a lot of workaound but nothing worked.
i saw performance improvement in reports by addding <trust legacyCasModel = "True" level="Full" /> in config file, But using this we are getting "Dynamic operations can only be performed in homogenous AppDomain" error
in many pages of our application.
Without SSO reports are running completely fine.
We are stucked here and not able to proceed. Is there any issue with the SSO and rdlc in local mode ? Is there any hot fix available for the same ?
Please help !!!
Regards,
Pranav Sharma

Adaptiva Software Distribution not working with Cisco APs in Local Mode

A worldwide customer would like to use a new Software distribution system called Adaptiva to replace SCCM within Windows environment. As far as I understand, Adaptiva is designed to work like a snowball system. A single PC at a remote side can be "infected" with new Software and will distribute the package to other PCs within the same IP-subnet, saving WAN bandwidth.
First tests are showing that it is working well with Cisco WLAN solution as long as we are using Flexconnect WLAN APs.
Customer locations with Local WLAN AP design create problems for this new software distribution method.
The WLAN-PCs can be reached from outside, but the establishment of the Client/Server-model between the WLAN Clients is not working. The Port used by this software for communication between clients in each WLAN subnet is UDP Port 34329.
Our WLCs are running at 7.4.130.0. The problem is appearing independently of AP Multicast settings or Broadcast Forwarding. Enabling Broadcast forwarding without Reboot did not improve the situation.
Global Multicast Mode and IGMP Snooping are also of no influence.
P2P Blocking Action is "Disabled" within the WLAN setup.
Who has any idea what might cause this communication problem between WLAN clients in Local Mode of APs ?
Thank You for answers

I can think of two solutions. You could 1: turn the "auto-lock" to never, so that your phone never sleeps. Or, you could 2: jailbreak your iPhone and install "insomnia". I wish we had the Cisco Mobile app. I usually use wifi/insomnia and turn data off at work since we have wireless pretty much everywhere...

Difference between bridge and local mode with wlc 5508

Hello,
Now i have wlc5508 with few ap 11xx 12xx in local mode. All work correct. I will have to add few ap1552 in bridge mode ( i have to wait for wlc upgrade to change ap1552 to local mode). My question is that all ( local and bridge mode) will work correct together for my clients: rfid readers, laptop, computer in a,b,g,n mode ? What about roaming and other feature ?
thanks for help
Peter

If you plan on not doing MESH, then you set these 1552's in local mode and they will perform the same tasks as any other AP's in local mode. When you want to do MESH, then that is when bridge mode comes into play and you have to define your RAP's and MAP's.
Roaming, clients devices, doesn't matter if your using local or bridge. roaming depends on your device and coverage and rfid, also depends on triangulation with the coverage you have now.
Thanks,
Scott

HREAP vs LOCAL modes

after reading through numerous docs from Cisco - it seems that latest firmware on WLC provides HREAP functions similar to that of using local mode. So what if the APs on a LAN are all set to HREAP giving you the benefit of redundancy and also network local switching avoiding that local traffic needs to traverse the WLC ? I know Cisco are still recommneding use of HREAP for WAN remote sites - but why not use it on LAN too ? The limitations are very few and most either relate to WAN type (which on LAN these do not apply) or else refer to when LAP looses WLC communication (at least it works in limited mode better than not at all like when it is set for 'local' mode. The HREAP does not use CAPWAP tunnel to encapsulate data traffic so I agree some security is lost but if security at the LAP end is not a big issue for client I still see all other features work with HREAP - like RRM / Roaming etc . so you get full benefits of WLC whne HREAP is in connect mode and keep some if WLC is down .. can anyine convince me otherwise ? : )

As per my usual on this type of question.
It all depends on what you want to do.
Yes, you can use the AP like they were autonomous, and bridge all the traffic down to the LAN if you want. Or you can backhaul it to the WLC. It's all up to what you need to support.
For example, if you were using Air Fortress, you would have to use HREAP, because of how that applicaiton interacts.
If you're only doing standard, web and email, there is no real need to.
Both designs are valid, all depending on what you want to do.
As for the security aspect of it, the traffic on the LAN isn't encrypted anyway. So once the traffic egresses the WLC, it's raw, if you have a protocol analyzer you can get the data. So that comes down to physicl security more than anything, not wired vs. wireless.
Cheers,
Steve

What happens if Local Mode LAP lost connection to Controller?

Hey,
I wonder what happens to the wireless client and LAP running in local mode if connection to wireless lan controller is down OR the controller itself is down? I do not think LAP will reboot by itself but will wireless client lost wifi connection and internet connection via the LAP?

H-REAP/FlexConnect is different and it can keep clients connected depending on authentication methods. This will explain it better:

HREAP vs AP local mode

Hello,
Could someone explain the advantages or differences in using HREAP (when the traffic is centrally switched), to just using the APs in local mode with a centralized WLC?
Scenario- 1 HQ and several branch offices. All resources are at the HQ including DHCP and internet break-out.
Thanks

Well it depends if the lwapp traffic takes up too much of your WAN bandwidth. If not, then run local.... I have clients that have gig connections to their branch offices that run every ap in local mode. I also have clients that run the branch office ap's in h-reap due to bandwidth constraints. Even though traffic will end up back in the central site doesn't mean you can't run the ap's in h-reap. The good thing with h-reap is that if the wlc becomes unreachable for some reason, the ap's will still be up and running. Encryption that can be run in local mode can still be ran in h-reap. The senerio that is in alot of docs is that if your wan goes down, users who need to authenticate back to a radius server in the central site will fail.... that is because the wan is down. Again, you can run locally first and see how that works.

Pop/Imap retrieving and redistribute in LAN with OsX Server

It's possible to download mail accounts hosted in my isp and redistribut'em in my lan with OsX Server with it's own mail server?
The scope is not to have a local server mail because we have ADSL and sometimes the line broke up...
We prefere have mail hosted more securely in our external isp.
But an internal mail server is a commodity very useful...
Sorry if the questions is answered before...
Thanks in advance.

Maybe not easy but should work:

# This is a 2 phase locking approach. LMT_REQ_LOCK is the outer lock and LMT_INVOC_LOCK is the inner lock
# We take this approach to ensure the scenario that, "At any point when an event occurs (AC/BATT), the

I had the problem but edited the line in /usr/sbin/laptop_mode and it worked. But thoes lines are not there anymore. I guess they changed it at the recent update of laptop-mode-tools.
Regarding your heat problem; is there any other thing you use to cut down power usage (from AUR maybe)? I use acpi_call from AUR had to edit lines there aswell, but it should be updated by now.

Nokia c2-02 showing local mode after software update

Wat is synchronous, asynchronous & local mode of update in BDC plz help

wat is synchronous, asynchronous & local mode of update in BDC .
plz explain each of them

A Asynchronous updating. In this mode, the called transaction does not wait for any updates it produces to be completed( does not wait till the update in database is complete either it is successful or un successful). It simply passes the updates to the SAP update service. Asynchronous processing therefore usually results in faster execution of your data transfer program.
Asynchronous processing is NOT recommended for processing any larger amount of data. This is because the called transaction receives no completion message from the update module in asynchronous updating. The calling data transfer program, in turn, cannot determine whether a called transaction ended with a successful update of the database or not.
If you use asynchronous updating, then you will need to use the update management facility (Transaction SM12) to check whether updates have been terminated abnormally during session processing. Error analysis and recovery is less convenient than with synchronous updating.
S Synchronous updating. In this mode, the called transaction waits for any updates that it produces to be completed. Execution is slower than with asynchronous updating because called transactions wait for updating to be completed. However, the called transaction is able to return any update error message that occurs to your program. It is much easier for you to analyze and recover from errors.
L Local updating. If you update data locally, the update of the database will not be processed in a separate process, but in the process of the calling program. (See the ABAP keyword documentation on SET UPDATE TASK LOCAL for more information.)

6151 Local Mode

I have a recurrent problem with my Nokia 6151, bought 2 months ago, that makes me think there is an error in the software.
I use to use to switch off the phone at night, while programming the alarm on the morning, to wake up. I have been doing this for years with other phones, also Nokia. But from the first day I bought the 6151 this was not possible, as the alarm did not activate, and on the morning I found the phone not responding al all, with the message "Local Mode" on the display, having to take out the battery to be able to use it again. I could see that this (showing "Local Mode" ) happened at the moment that the alarm was programmed to activate.
Firstly, the shop changed my phone for another one (same model), but the problem was the same.
Then the phone was sent to the Nokia Service, and after 3 weeks they told me that had updated the phone software.
After this, the problem persists.
What can I do?Message Edited by monsalvegf on 05-Aug-200705:11 PM

SIMILAR:
I bought myself 1 month ago the mobile Nokia 6151.
Initially, 3 ó the first 4 unloads, when it(he,she) was setting it to load I was leaving on the screen "LOCAL MODE " and the symbol of load was not seen. The battery was difficult to me to fit until I was achieving that I was loading. I changed the following adjustment:
Menu - Adjustments - Adjustments of the telephone - Way of network(net) and I selected "GSM"
With this change, from then, it loads the first one.
But this week I have started using the alarm of the mobile and the alarm does not sound. It has spent(passed) 2 times.
In this moment when I look at the mobile me there appears on the screen the same text: "LOCAL MODE ". I try to ignite the mobile but it's not possible. I have to extract the battery, turn it to placing and this way the mobile is ignited.
I do not understand that it happens ...! Is it a failure of the mobile, of which I have formed badly the mobile or that?
I have consulted the user guide but I have not found anything about this. I would like that you were helping me to solve this topic, please.

How to cleanly migrate APs from local mode to flex-connect?

I am working with an existing network where all APs are remote from the WLC at the data center. All APs were configured to run in local mode. I am trying to reconfigure these APs to flex-connect mode and local switching.
Configuring the APs themselves to flex-connect and reconfiguring the switch ports is not an issue.
None of the WLANs are currently configured for flex-connect local switching.
When I configure a WLAN to allow local switching several of the APs cease to service clients.
I am not permitted to change/add a new WLAN so I have to do this in place. This has to be transparent to the users.
Any thoughts would be appreciated.

The AP has been changed to flex-connect mode from local and the native VLAN is set to 10. The switch port is trunked with the native VLAN set to 10. This works fine until I try to change the WLAN to allow local switching.
This example is a small site and all data clients are assigned to VLAN10.
