Two WLC over the same SUBNET - selection from AP for determinate WLC

Hi
I have the next problem, my company have two WLC (WISM1 - IOS 7.0 and WLC2504 - IOS 7.4), and we have 4 types of APs (1131, 1242, 1040 and 1600), well the WISM 1 manages the old APs 1131, 1040 and 1242, the 2504 manages the 1600, this because the WISM 1 don't support the 1600
Well my question its how i can assigned to APs 1131, 1242 and 1040 to connect to WISM1 and not to 2504 , both are on the same subnet and the Ip its send for DHCP with option 43, others for DNS and apparently some of my APs connected to the 2504, I wish only connect to WISM 1
How i can set priority in the AP for conect to WISM1?, i read the High Availability on the AP, this is enough or should we make any extra settings the WLC
Thanks for the response
Regards

Hi Kashif,
I don't think you understand the nature of this thread. It is IMPOSSIBLE to configure a 2504 & a WiSM-1 for HA (AP SSO).

Two controllers on the same subnet

One of our office that already has 1 2000 controller needs to install another one. Can the new controller be on the same subnet as the old one or does it have to be on a different subnet?
thanks

Roaming is an 8 hour conversation in itself, but I will answer your question with a 'yes', you should have a mobility group defined if wireless clients may move between APs associated with different controllers.
Roaming actually has much more to do with the wireless security in use, the config of the client and back-end user database, and the layer 2 connectivity of the multiple controllers.
If you are using WEP or WPA pre-shared-key with the same layer-2 termination on the controllers, then your users really aren't 'roaming' at all, they are constantly re-associating to the different APs anyway.
Roaming, in my mind, means 'fast roaming' meaning less than 100 ms. This would require either Cisco proprietary CCKM, or some of the *sort of* WPA2 fast-reconnect features.

How do I use the same Apple ID from iTunes for iCloud?

Ok, I know this is probably a really stupid question, but I recently (like, 2 weeks ago) got a MacBook Pro after my older MacBook from 07 decided to get a mind of its own and start going on the fritz. Anyway, I had an older OS on my MacBook and therefore did not have iCloud at all. So for the past two weeks I've been trying to set up my iCloud on my new computer (who's name is Schroeder, for those who are wondering) and I've been attempting to use my Apple ID to sign up with for it (my Apple ID is the same as my regular email address). This is what I get when I try to get into my iCloud: "This Apple ID’s email address cannot be verified. Change your Apple ID’s email address at appleid.apple.com to sign in to iCloud." The thing is... my email address/Apple ID has already been verified. I was paranoid and verified it multiple times, too, and I still get the same "This Apple ID’s email address cannot be verified. Change your Apple ID’s email address at appleid.apple.com to sign in to iCloud" message when I try to sign into iCloud. What's going on here? Am I doing something wrong?

- Apps are prementently tied to the account that purchased them and you have to sign into that account to update the apps. If you have apps that need updating from more than one account you need to update them one at a time util the remainig apps were purchased from one account.
- Go to Settings>Store to sign out and sign into anohter account

Two different Routers and same subnet, is it possible?

Hi i have been presented with a problem that a friend of mine is having.
There is two different Cisco routers on different location.
example:
router1 : 10.8.10.1 (has DHCP/FTP server)
router2 : 10.8.12.1 (needs to talk to DHCP/FTP server on router1)
the router2 has different ip configured but is it possible to change this to the same subnet as router 1? like 10.8.10.4?
The DHCP/FTP server have been defined with scope 10.8.12.0 and on the Cisco switch on router2 its been configured (ip helper address DHCP-IP)
this works, the clients connected to router2 gets ip from DHCP server ,but there is no FTP traffic.
i figure its because the DHCP/FTP server doesent understand the other IP, so if its possible to setup a kind of mulitVPN to get the same subnet on router2 as router1 the FTP server can "see" the other router2 because it has the same subnet and ip range.
Thank you for any experience, i really stuck on this one

John,
to simply put it having two routers on the same subnet is not possible as the purpose of a router is to route traffic between DIFFERENT networks. In order to accomplish this you will need routers and switches that understand VLANs and VLAN tagging.
Hope this Helps

Two clients in the same server--Script??

Hi Folks,
1.I have two clients in the same server say 100(used for dev) 120(used only for testing).I had developed a script in 100 which I want to test it in 120.Now how to move this script in 100 to 120.
2.How to use includes in scripts and what is the usage?
Thanks,
K.Kiran.

<b>INCLUDE: </b>Include other texts
With the command INCLUDE, you can include the contents of another text into your text. The text to be included exists separately from yours and is only copied at the time of the output formatting.With the INCLUDE command, you always get the most current version of the required text, since this is only read and inserted during the output formatting.
Syntax:
/: INCLUDE name [OBJECT o] [ID i] [LANGUAGE l] [PARAGRAPH p] [NEW-PARAGRAPH np]
The name of the text to be inserted must be specified and can have up to a maximum of 70 characters. If the text name contains blanks, then you must put it in quotes as a literal. It can also be specified via a symbol. All further parameters of the INCLUDE command are optional. If they are missing, SAPscript uses default values for them which are based on the respective call environment.
Examples:
/: INCLUDE MYTEXT
The text MYTEXT is included in the language of the calling text.
/: INCLUDE MYTEXT LANGUAGE E PARAGRAPH A1
The text with the name MYTEXT and the language E is included, regardless of in which language the calling text is created. The paragraph format A1 is valid as the standard paragraph for this call.
Optional specifications:
LANGUAGE If a language is not specified, the language of the calling text or the layout set is set for the text to be included. If a language is specified, the text is always loaded in this language, regardless of the language of the calling text.
PARAGRAPH The text to be included is formatted with the style allocated to it. With this parameter, the standard paragraph of this style can be redefined for the current call. All * paragraphs of the inserted text are then formatted with the paragraph specified here.
NEW-PARAGRAPH The first line of the included text has this format flag, provided it is not a command or comment line. If the optional entry PARAGRAPH (see above) is empty, all * paragraphs of the included text are formatted with the paragraph np specified with
NEW-PARAGRAPH.
OBJECT To specify a text completely, you must make further specifications regarding the text object. There are different rules and restrictions for this which depend on the object type of the calling text: All texts can be included in a layout set. If no object is entered here, TEXT is used (standard texts).With a documentation text (object DOKU), you can only include documentation texts. This object is assumed even if no object is specified in this environment. Only hypertext or documentation text can be included into a hypertext (object DSYS). If the OBJECT specification is missing, DSYS is set as a default value.
Only standard text (object TEXT), documentation text or hypertext can be included in any other type of text. The default object is TEXT if nothing is entered.
ID The text ID, which allows further text types within an object, is a further part of the text key. If the ID is not entered, the default Include ID from table TTXID is used for the calling text. If the specification is not in this table, the text ID of the calling text is used.
The ID together with the object are now the basis of a further consistency check:
All text IDs are allowed for a layout set.
Only documentation texts with the text IDs TX (general texts), UO (authorization objects), and documentation texts which have the same text ID as the calling documentation text may be included in documentation texts.
All DSYS texts may be included in DSYS texts, regardless of their ID. Documentation texts to be inserted may only have IDs TX and UO.
Standard texts with all the allowed text IDs, DSYS texts with all IDs, and documentation texts with Ids TX and UO may be included in the other types of texts.

Can't put two 5508 WLCs in the same RF group

Hi experts,
I have two 5508 WLCs and I want them to be backup to each other. I put in the same "RF Group Name" and even the same "Default Mobility Domain Name" however under Wireless -> 802.11b/g/n -> RRM -> RF Grouping each controller still only have themselves as the only memter to the group.
Two controllers are having management IPs on the same subnet 192.168.161.x/24. AP-manager interfaces are in the same network as well. They can ping each other fine. The following screen shots show the current relavent config on the controller:
I do have two controllers in the same mobility group and they are both showing up...
Does anyone know why they can't add each other to the RF group? All other settings are pretty much default...
Thanks!

Hi,
is there a chance that one of the 2 WLC doesn't contain any access point ? Or that the APs from one WLC are not physically close to the APs of the second WLC ?
The point of RF grouping is to exchange RF information, to make RRM decisions together and to know what ap is a rogue and which is not. RF group information travels over the air from AP to AP.
So if a wlc has no ap of if its APs are not close to those of the other WLC there is both no point in grouping with the other WLC in rf group and also no technical way of doing so.
Regards,
Nicolas

In iPad 1 ios 4 may have two ipad Apps the same from two accounts itunes

In iPad 1 ios 4 may have two ipad Apps the same from two accounts itunes one free other paid account, hence one free App and another paid App the same App?

If both accounts are authorised on your computer's iTunes (Store > Authorise This Computer) then you can download the books from both accounts to there (download the books from one account, then sign out of it via Store > Sign Out, log in with the other account via Store > Sign In and download the books from the other account), and sync them over to the iPad's iBooks app via the Books tab.
Or you might be able to sign out of your account on the iPad by tapping on it Settings > Store and sign in with the other account and download the books from that account - I think that it should work, but it's not something that I've tried so I'm not 100% sure that it will

Is it possible to run two different versions of Apple operating system (for ex. 10.6.8 and 10.9) on a MacBook Pro, either on the same disk or from an external hard disk? If so, where would I find the details?

If you want to add a second partition to the internal drive (in Disk Utility, select the drive, then open the partition tab and just click the + button), you should first be sure that you will have enough room to accommodate whatever the second volume will be. I am currently doing this for Snow and Mountain Lion.
To get to whatever volume is not the startup disk, restart and hold down option/alt at the chime, which will bring up a selection of the two volumes. Use the left or right arrow keys to select it and then hit enter/return.

How do I load balance TFTP between two servers and a client on the same subnet?

Hi,
I have trawled through several documents and tried umpteen different configs, all to no avail. I have a PXE boot client trying to access a boot file via TFTP from a couple of TFTP servers on the same VLAN/subnet. For HA purposes I want to load balance the two TFTP servers.

I have read the doco by Ivan Kovacevic amongst many others but as my clients and servers are on the same subnet, the config doesnt work.
Can anybody point me in the right direction please. The devices are ACE 4710 running A3(2.3).
Thanks

Try using the following configuration:
Note: Please make sure to configure also a udp probe to probe udp port 69, in case the application is down.
You need to configure a management policy on the interface when using a UDP probe.
That is because, when port 69 on the server will be unreachable, the server will send an ICMP unreachable.
ACE will consider a udp probe as "failed" only when it sees ICMP unreachable.
Without a management policy-map, the ICMP unreachable message will be dropped.
Also, add an ICMP probe to the rserver because udp probe will not be enough when the physical interface will be down.
That is because UDP is a connection-less protocol. To consider a UDP probe successfull, ACE need to see NO answer from the server in respose to the probe.
The ACE will not see any answer from the server when the interface is down and thus, will consider the probe as "sucessful".
With ICMP probe attached to the rserver, you also test the reachability of the server and not only the UDP port.
Here is the configuration (of course, you can chage the names of the of the objects to the name you are using if you want) :
access-list ALL line 10 extended permit ip any any
probe udp TFTP
port 69
interval 5
passdetect interval 15

[Bug] Writing to the same trace in Citadel from two Sources at the same time

Howdy
I am experiencing an issue and am looking to get some NI support:
I have two distributed applications that can write to a Citadel database at the same time.
And I am investigating the possibility of what would occur if both of them were writing to the same variable at the same time, with possibly the same timestamp data.
I did this in the attached VI by using the same timestamps with a constant for the data (either #1 or #2).
This generates an error, as expected, stating you cannot have two references open at the same time.
The data file, dumped from Citadel, contains 1000pts with all data from only one of the arrays (in this case #2) and everything looks fine:
However, what appears to be happening randomly tho, is that the same portion of code can also returns no error.
When the data is dumped from Citadel this file contains 2001pts - 1000pts from each array and one separator (or break) point:
You cannot write an older timestamp to Citadel without it throwing an error, but from further testing it seems you can write the same timestamp repeatably. So I am guessing what is happening above is race condition that is somehow allowing two references to be opened to Citadel which should throw an error but it does not and this is somehow allowing both sets of data to be written by both loops??
The data, IMO, is now corrupted.
Is being able to write to the same timestamp a desirable feature?
Or is this a known issue or a bug?
What about acquiring two references - bug?
Is there a workaround to protect the data from multiple distributed-application writes?
Cheers

Is it possible to create two multicast DR on the same subnet?

on server vlan 10.24.254.0/24, there are two routers:
R1 is .2 and R2 is .3 with "IP pim sparse-mode" enabled.
R1 and R2 are on two distinct Mcast domains
R1 has
ip pim rp-address 10.25.249.1 acl-one override
R2 has
ip pim rp-address 192.168.2.1 acl-two override
The problem is R2 with higher IP address is now the IGMP and PIM DR. Any multicast app with RP 10.25.249.1 is NOT working because R1 can't receive IGMP join from servers.
In addition, R1 by design can not reach 192.168.2.1 and same for R2 to reach 10.25.249.1
Thus configuring two "IP PIM rp-address" is not possible
how can I make R1 the DR for group IP under acl-one and R2 for group IP acl-two?
or I have to change network topology?

There can be only one DR on a the same subnet.If there are more than one DR on the same subnet it would endup sending duplicate multicast traffic for connected host.For more information refer the URL

Hello there - how can I share my iTunes library between two users on the same computer? I put the library in a shared folder between both and have selected this library on both as well, but when I update iTunes with music etc it only appears on one?

Hello there - how can I share my iTunes library between two users on the same computer? I put the library in a shared folder between both and have selected this library on both as well, but when I update iTunes with music etc it only appears on one?

Thank you Joe - I tried this but it's only showing a teensy amount of music - the stuff on the second users account as opposed to the giagntic library on the 'main' account. I actually went to a Genius Bar and they said that apple doesn't really want you to share music between accounts - parents don't want to hear their kids music etc. Which seemed strange, but it might be the case sadly Thanks anyway!

How do you stop your phone from creating two albums with the same photos after syncing?

When I first bought my phone I was able to sync my photos by checking the folder I wanted synced under iTunes. This put all those photos on photo library on my phone. I recently added more photos to that folder and tried to sync them it now put them in the photo library album and also created another album with my folder name. So I have two albums with the same photos. I tried in checking that folder in iTunes and of course they're not in my photo library. Please help. I don't want two albums with the same pics

This is how Apple has always handled photos. nothing has changed at all.
Just as your music is in your library and you can access those exact same songs from a playlist, all of your synced pics are in the Photo Library and those exact same photos (NOT duplicates) can be accessed from the album name that you chose to sync.
