Controller failover for different controllers

Hi,
I have 3 existing controller with different model, capacity, version and configurations. I have purchased new controller that supports 100 APs.
Let's say WLC_A has a capacity of 25 APs and caters 20 APs, WLC_B has a capacity of 12 APs and caters 12APs, WLC_C has a capcity of 50 and caters 30APs. the NEW WLC, WLC_NEW has a capacity of 100 and will only have 18 APs registered to it.
What will be the requirement for me to have WLC_A, WLC_B, WLC_C failover to WLC_NEW, given that all OLD WLCs have different version and configurations? We are trying to make this as HA as possible.

Let me try to explain this a little better. If you have the following like you posted earlier and all these WLC's are located in the same building and you mobility between the two. When a user roams from one WLC to another, it will break and the user will have a hard time accessing the SSID. This is because you changed the security method. You can't apply multiple security profiles on a client.
WLC_A
SSID: Guest
Security: none
VLAN: 20 SW_A
WLC_B
SSID:Guest
Security:web auth
VLAN: 40 SW_B
WLC_NEW
SSID:Guest
Security:WPA_PSK
VLAN: 20 SW_NEW
What you need to do is define your wireless requirements (SSID & Security method) You want to have the same SSID have the same security method and preferably have the dynamic interfaces on the same subnet if your L2 to the access.
This is how you should have guest as an example. All the WLC should be in the same mobility group!
WLC_A
SSID: Guest
Security: WebAuth
VLAN: 20 SW_A
10.20.10.20/24
WLC_B
SSID:Guest
Security:WebAuth
VLAN: 20 SW_B
10.20.10.21
WLC_NEW
SSID:Guest
Security:WebAuth
VLAN: 20 SW_NEW
10.20.10.22
This setup will allow users to roam from one WLC to another seamlessly.

How do I set up different hardware controls for different patches in mainstage?

I'm using Mainstage 3.0.4 and a Novation Impulse.
I created a concert, with the drawbar organ as my first and most important patch. I assigned the hardware controls on the Novation exactly how I wanted them, with the sliders controlling the drawbars, and the rotary controls changing the distortion, reverb, etc. It was perfect. I was happy.
Then I added a new instrument (a new patch, not a new channel or anything like that), a Wurlitzer. Once again I assigned my hardware controllers as I wanted them, and was happy with that.
When I saved the concert, and went back to my organ patch, my settings didn't stay the same, but they still work for the Wurli.
My question is this - do I have to have a new concert for each instrument patch I want to use, if I need to assign different controllers for each patch? This would be stupid! If not, what I am doing wrong, that I can only set up one set of hardware controls per concert, instead of per patch?
Thank you in advance for the help!!!

CCTM, thank you! I have a small idea what you mean, but I still can't implement it :-)
You have some fundamental choices:
A) If you want to see Drawbar Controls for organ Patches, and then have other types ( knobs/sliders etc) for other Patches, you could simply make all the screen controls you need, then assign and map them as required.
B) you could simply use drawbar screen controls only and remap them to other parameters for non-organ patches
C) You could use Smart Controls ( which will update their appearance in a 'smart' way
D) You could make your own Drawbar type controls using standard faders
The basic process in a 2 part thing:
Assign incoming MIDI messages from your controller to Screen Controls in Layout mode. This is global for concert. Per patch ( or Set or globally for the Concert) you then map the Screen Controls to parameters for each patch as needed.
Smart Control MIDI assignment is done in the Assignments and Mappings pane

Controller Failover Scenarios - 5508

I am putting a design together for a resilient wireless network.
I have 2 main data center sites
Site 1 I will have either:
1 x 5508
1 x 5508 + HA
2 x 5508 in N+1 failover
Site 2 will have just one 5508 controller.
What failover models are available to me?
Can I have an option of N+1 with also a failover to Site 2 if Site 1 is down
From my initial research I think I can can only configure AP's to have a primary and secondary controller configured.
So think the best model is an HA pair in Site 1 and the 5508 in Site 2
What I don't understand yet is the controller to controller failover?
I will be running a guest network out of Site 1 and require the controllers there to be the anchor
Any advice is appreciated.
Thanks
Roger

You can have various designs:
Option 1:
You can have AP's on both WLC's to off load traffic
Site 1:
5508 with license
Site 2:
5508 with license
Option 2:
You have AP's on one WLC and the other is backup
Site 1:
5508 with license
Site 2:
5508 HA sku
Option 3:
You run N+1
Site 1:
5508 with license
5508 HA sku N+1 (Secondary)
Site 2:
5508 HA sku N+1 (Tertiary)
Option 4:
You run AP and Client SSO
Site 1:
5508 license
5508 HA sku AP SSO
Site 2:
5508 HA sku N+1
Option 5:
Run both sites with AP SSO
Site 1:
5508 license (Primary)
5508 HA sku AP SSO
Site 2:
5508 license (Secondary)
5508 HA sku AP SSO

How to plan Failover for the following Scenarios in Flex-connect mode.

The following queries are in respect to AP High availability (not SSO fail over or Controller HA), meaning if one controller fails, the AP will be failing over to the secondary controller which is in a different Geo location. the AP will be in Flex-connect mode with local switching and local auth. in this scenario, following are my queries
1: If i have an SSID that has an interface group linked to it, can i fail it over on other controller where there may be a single WLAN linked to it.?
2:Do we need the subnet masks to be same at both ends?
3: if i have an SSID with open authentication, can i configure the remote network SSID with no authentication?
4: can any one link me up with a document that explains configuration case study of the flex-connect mode fail over scenarios.
All the help given would be really appreciated.
Thanks.

hi Scott,
Sorry for replyimg late. and thanks for your reply and suggestion.
it did help me a lot, but now i am in a tiff.
the thing is my client has following existing scenario:
he has 6 disparate locations with a standalone 5508 WLC at each location.
he is now planning to configure AP failover for every location.
we are using the Flex-connect design as he has not procured a HA-SSO license.
also the WLC are not in same location.
the Flex-connect design is with Local Switching and local Auth.
there are 2 SSID which are causing me issues.
1: SSID A is linked to an interface group which has multiple vlans.
2: SSID B shares its WLAN interface with another SSID (the wlan is split between 2 different SSID)
we need local switching for these and also they need to have local auth.
so if i remove the interface group for SSID A and use a bigger subnet, what will be the best possible mask to use considering that the ARP and DHCP broadcast shouldn't choke up the network (existing subnets are /21 and /22). or any workaround to minimise the network activity.
and for SSID b what is the configuration i would need to do on the secondary controller or is it just that the SSID needs to be present on the controller and the mask need not be same.
sorry for troubling you and thanks in advance

Jerks only when connecting RAID on different controllers

Hello,
I am trying to connect my two new hard disk (2 x Western Digital 160gb ATA100 7200rpm 2mb - OEM) to my on board raid controller on my KT3 Ultra boards.
If I connect them on the same IDE cable to controller 3 then they work fine.
However if i connect them to different controllers (3 and 4) then my PC will stop responding for a couple of milliseconds every minute or so.
Should they work better on different controllers?
I've updated all my drivers and bios.
I run windows XP on an AMD XP1900+, 756mb Ram, Geforce 4 ti4200.
I also have two older 80gb disks connected as master and slave to controller 1 and a DVD drive and CD drive connected to controller 2.
Any suggestions would be greatly appreciated
Kind regards,
Matt Jordan

ahh...
I tried setting them up as masters each but they werent being found. I then changed them to both being slaves and they worked. But that was while it was giving me that problem.
So do I just need to set the to stand alone by taking the jumpers off?!
Thank you very much

Oracle DB Can't Survive ZFS SA Controller Failover

We are running two new Sparc T4-1 servers against a ZFS SA with two heads and a single DE2-24P disk shelf. It is configured with a single pool for all the storage. Our servers are clustered with VCS as an active/passive pair, so only one server accesses storage at a time. The active server runs the Oracle Enterprise DB version 12c, using dNFS to connect to the shares. Before deployment, we are testing out various failure scenarios, and I was disheartened to see that the Oracle DB doesn't handle a controller failover very well. Here's how I tested:
My DBA kicked off a large DB import job to provide some load.
I logged in to the secondary head, and issued "takeover" on the "cluster" page.
My DBA monitored the DB alert log, and reported everything looking fine.
When the primary head was back online, I logged in to it, and issued "takeover" on the "cluster" page.
This time things didn't go so well. We logged the following:
Errors in file /u04/app/oracle/diag/rdbms/aasc/aasc/trace/aasc_arc2_1296.trc:

My DBA said that this was a very risky outcome, and that we certainly wouldn't want this to happen to a live production instance.
I would have hoped that the second controller failover would have been invisible to the Oracle instance. What am I missing?
Thanks.

Using several UMTS access points (APN) for different services

Hello,
I wonder if it is possible to use several UMTS access points (APN) for different services.
situation:
1) The iPhone is used for business AND private purposes.
2) The company's mobile telephone contract includes a APN, which is only usable by the employees' mobile phones.
problem / question:
Is it possible to define two access points in the iPhone, that for example the exchange account uses the company's APN, while all the other apps use the standard APN of the carrier?
Problem is, that some iPhone's benefits like Push-Messages are blocked by the carrier's APN. Now, I have to switch the access point by installing the appropriate profile every time I want to check my e-mails or vice versa for using "normal" apps.
I hope you can hep me.

Thanks for your help! This really helps a lot! We actually only want to replace the autonmous access point with the controller solution and make one WLAN available at another site. From what I can see, this is possible with our current solution - we just need to switch from Layer 2 to Layer 3 and purchase the corresponding amount of supported Access Points (I think we should be able to get some refurbished ones).
Am I correct in assuming that the Access Points we want to replace (AIR-AP1230B-E-K9 with 802.11b radio only) cannot be upgraded to lightweight ones? Since if I understood document http://www.cisco.com/en/US/docs/wireless/access_point/conversion/lwapp/upgrade/guide/lwapnote.html correctly, this is not possible with access points that only have 802.11b radios.
Regarding the switch from Layer 2 to Layer 3: Do we really only need to perform the steps I described in my first post?
And one last question regarding REAP. As far as I understood this is only needed when local traffic needs to be maintained in case the connection to the WLC becomes unavailable. So we really don't need it if we want to access resources that are only available over the WLC?
Thanks again for your help!

LWAPP AP moving to different controllers

I have define three controller IPs for a specific LWAPP AP under wireless settings on the controller. On what scenario the AP will join the different controller except the three controller which was defined.

The AP would go to a WLC outside the primary/secondary/tertiary that it is configured for only if it failed to join all three of the WLC.
It would then try to join any other WLC that is. I figured in the mobility group. If there are no other mobility members, it will them fall back to the standard discovery methods.

Using multiple apple id's for different purposes

We are a family of 4 with numerous devices. Here's the setup we've been using to manage different aspects of our apple life!
Each of us has an individual apple id, which we use on our individual devices for storage/backup, photo stream, facetime, calendar etc
We have one apple id, used on all devices for all app store/itunes purchases
We entered this id on each device with everything turned off except "find my iphone". This way we could be logged into the find my iphone app with one id and be able to see all our devices.
This has worked really well for us as a family. Well, yesterday my kids updated their phones (one 5 and one 4s) to ios 7. I have not done it yet. It does not seem to allow for the above setup, specifically where "find my iphone" is concerned. When I enter in that specific apple id as an additional icloud account, it doesn't offer the option of find my iphone. My ios 6 device says "only your main account can use photo stream, documents & data, and backup". Their device adds "find my iphone" to this list.
Does anyone know if this is a specific change apple made, or something that went wrong when initially setting up their updated phones.
TIA!

Thanks for your reply. But what I don't understand is, can I no longer have multiple icloud accounts, to be used for different purposes? Like I said, we have been using one apple id/icloud for storage etc and one for find my iphone.

[SOLVED] how to use diffrent iptables rules for different ppp account?

x86 plantform run arch linux system , have two network interface etn1 eth0 .eth1 connect to internet. eth0 connect to other terminals through switch. want use different iptables rules for different pppoe account .also want to know how to forbidden more than one terminals established pppoe link use same account at the same time .
Last edited by linuxsir (2013-09-26 06:48:01)

(You establish PPPoE sessions over the local network to the Arch machine? Which then routes the traffic?)
first question ,yes that is exactly what i am done. second question i also have a small scripts on windows pc to solve routes traffic problem
route -p delete 0.0.0.0
route -p add 192.168.9.0 mask 255.255.255.0 192.168.9.1
route -p add 0.0.0.0 mask 0.0.0.0 192.168.22.0
but after a while i found scripts is not necessary because windows always attempt to use PPPoE sessions as default internet connection local connection is also ok
and use -i pppX in my iptables rules dose not solve my problem , because same account start PPPoE session could be marked as ppp0 or ppp1. it is hard to identified which account start session.

Is there a way to create a custom screensaver with pics/slides that display for different amounts of time?

Is there a way to create a custom screensaver with pics/slides that display for different amounts of time? Or even add a "video slide" into the screensaver?
My business has 3 TVs displayed in our lobby, each with its own apple TV and they are all linked to the same photo stream. Currently the Atv screensaver displays the photostream pictures of our products for the default 3 seconds. We just added pics/slides that now display messages and useful info for our customers but I want that info to be displayed for a longer period of time than the pictures to give people a chance to read it.
I tried using flickr and powerpoint as a work around but no luck. I created a slide in powerpoint with play length of 15 secs and saved it as a wmv file. I added that file to a "screensaver" set in flickr and pointed the Atv screensaver to that flickr set. It still displays everything, pics and the wmv file at the default 3 sec.
I know I can increase the duration of all pics in the screensaver to display for longer but the goal is to have the pics display at 3 secs and the info slides to display at 15 secs.

Welcome to the Apple Community.
No that's not possible.
If you have any suggestions that you think might enhance the Apple TV you can send Apple your feedback here

Creation of forms in Custom list for different departments in share point online .

Hello ,
We are using office 365 E3 plan in our organization.Recently we got a requirement from the management to create forms for different departments.I will explain a bit more on requirement.
We have three departments A, B & C .We want to create a form in such a way ,fields varies based on their respective department .If a form has 30 fields to fill , dept A fills
only first 10 fields which they need and will forward the form to next dept to fill remaining fields.Here when Dept A forwards the form the first 10 fields has to be hide for other depts .when Dept B and C logged into their accounts to fill the form only their
fields need to be available in the form and remaining options has to hide .After filling all fields from different dept . After filling the forms Dept A can see all the fields to check the data .
Any one can please help me out how to initiate the process to meet this requirement.

The simlest approch for you is to create 3 different list with 3 different forms. But you can update their connection string to store the data(xml) in same list or different list
Or try below:

HR Authorisation Management for different companies in the same client

Hi,
Could anyone please help in this....
My client has two companies. They want to restrict the authorisation to both the companies so that no one can see each other companies data and at the same time access tha data.
For Eg, there are two payroll officers, each in both the companies, If i give authorisation to run Payroll driver(PC00_M40_CALC), anyone of them can run payroll for any of the companies. (though,their Payroll area is different). There are many restrictions to be maintained like Maintance of Master data, Maintanance of OM structure as assignement of position, running Payroll, viewing the payslip etc...
How can this all be restricted so that, the respective companies can view and access their own data without interfering in to the other company.
I could only find object P_PYEVRUN which helps me restrict to view the created documents of posting for other company code.
Can anyone put light on how i should proceed further... I heard we can restrict HR master data, but what all i know is we can restrict at infotype level. My problem is, two persons should access PA30(each from different companies), but should not be able to edit other companies data.
Thanks
--Pranitha

Hi ,
If you are creating the another company undar the same client . then you can not use different no. range.
or if you are going different client for different compnay code then you can use different number range for material master.

Exchange phone for different kind

I just bought the Bionic a couple days ago and I'm completely dissatisfied with the phone. Can i exchange it for a different phone like the Razr? What is the process of doing this at the store and what time frame do I have to take care of it? Recieved phone on 11/17/2011. I heard that this is an extended period to return/exchange a phone due to the holidays, cause I know it was 14 days, but now it has changed. I realize that i would probably have to pay a restocking fee of $35.00 when returned, but want to know exactly what needs to be done to exchange it for different phone entirely. Any help will be appreciated.
I had another question about exchange. If I purchased over the phone on 11/16/2011 and recieved the phone the next day on 11/17/2011 instead of in the store, would I have to send back my bionic first before I could get the Razr as exchange or would they send me the Razr and have me send back the bionic when the Razr arrives, so at least I have a cell phone until then. Thanks again

you have 14 days to schange the phone
you can only do this ONE time
you will pay the restocking fee and any cost difference
you should be able to do it all in store
this all assume you bought it from verizon and not a 3rd party such as amazon/wirefly/ect

Leave Quota generation with diifferent rules for different countries

Hi,
I have the following requirement need help in achieving this.
Employers must grant 10 days paid leave to employees that worked for six consecutive months from the time of hiring and who worked on not less than 80 per cent of all schedule work days. This paid leave may be taken consecutively or separately. Where an employee's application to take paid leave will hinder the normal business operations, the employer may require the employee to take such paid leave at a different time.
The number of days of paid leave available to employees increases in proportion to employees' length of service as set forth in the below table.
Years of Service 0.5 1.5 2.5 3.5 4.5 5.5 6.5+
Paid Holidays 10 11 12 14 16 18 20
The right to annual paid leave expires after two years. In other words, annual paid leave left over from one year may be carried over and taken the next year only. For example, if an employee is awarded 10 days paid leave after their first 6 months of employment; those paid holidays will become invalid after 2.5 years of employment. Use them or lose them.
Simply put, holidays from one year can be carried over to the next year, but not to the third year. So, if you don't take your leave from one particular year within 12 months of that year ending, you will lose that first year's allowance.
Employee can take leave encashment of holiday leave only when leaving their employer. It is not legal for companies to buy up the holiday leave of those still working for the firm.
In my organization one PSG grouping has been used for all countries, it wont be possible to change the grouping now. In such a case how can we provide different rule for different country without customizing the Leave module.
Do we have to use any PCR for this, if yes which??

Jailakshmi

Hi,
Use QUOMO Feature to give different entitilement to employees.
Leave entitlement as per seniority can be configured in base entitlement.
Keep validity and deduction period for 2 years by using :Relative postion" option in validity and deduction period table.
