2504 WLC HA sku Using N+1 -- What code to use?

Just need a little direction please, could anyone tell me if N+1 is supported in 7.4.121 code using the 2504 HA sku WLC? I am finding some conflicting information on Cisco docs and forums. If not, what would be the most stable code to use that would support N+1 with the 2504 HA sku?

Hello Britain , Starting with Release 7.4, the -HA SKU can be used in N+1 mode. After 90 days, a daily reminder about reconnecting the primary controller will be sent to the network administrator.

How-do-i-configure-guest-wifi-access-using-2504-wlc-fortigate-utm-l3-device

Dear All
I have a 2504 Wireless Controller with multiple radios attached. I currently have a "private" WLAN configured (taking ip from windows server based DHCP of Range 192.1681.0/24 ) and working, but I need to add a Guest/Public WLAN which should take the IP from Other DHCP Configured on Fortigate UTM of range 172.16.0.0/24.
We have one SG300 switch in the office and the rest are basic switches.
Our firewall/router is a Fortigate UTM 240D
Find the attached network diagram for the issue.
Is there a SIMPLE way to enabling guest access that doesn't require VLANS (or are VLANS easier than I'm making them)?
Thanks.

Configuring Guest Access using 2 LWAPs and 2504 WLC

Please advise,
I have 2 APs, Cisco Aironet 1040, and 2504 WLC.
Is it possible to configure guest access (Guest SSID/VLAN and Corporative SSID/VLAN) without dedicated guest WLC in DMZ?

Yes you can. You can have up to 16 SSIDs per AP, but not suggested to have all 16. You can either use one port on the 2504 for both SSID/vlan or specify which port is for corporate and which one is for guest.

Local printers not working with 2504 WLC

                   I have a 2504 WLC with 3 1262 WAPs in lightweight mode.
     Clients connect using WPA2 PSK AES with no problem. Clients are Windows XP Home SP3. Test pages end up in print queue and eventually get a error printing status. Clients are not part of a domain and in a standalone workgroup - techstream.
Printer can be pinged from wireless client.
Another 1262N WAP in standalone mode connected to same lan from windows 7 sp1 clients have no problem printing to a local printer.
What does work on the Windows XP Home client is connecting to a network shared printer authenticating with domain admin id and password and it works. Reboot and the network shared printer can not connect multiple reasons are "access is denied" and message box says "only security tab will be displayed....."   Another Windows XP Home SP3 client on reboot can't open the network shared printer with message "Can't find printer"
The local printers do work on these pc's with an old colubris router that has an outside interface on our lan and internal network with clients getting dhcp address from colubris router of 192.168.3.XXX .
What is wrong with the wireless 2504 WLC?
Thanks
Broadcast forwarding was enabled.

Although a cisco tech support was helpful in making sure multicasting was enabled and a multicast server defined, the problem was at the CP2025DN printer. It had old network ip mask and gateway configured on the printer.
The new devices were part of the new network configuration (Mask and gateway had changed). I didn’t change that printer when I changed all the other printers at the facility because it was still active thru the old wireless network. I forgot to change the printer ip config when I brought the new wap on the new wireless network with the wlc 2504.
End result was the clients were part of a different subnet and gateway configuration then the printer and this disrupted the communication between clients and the printer. Once I corrected the mask and gateway on the printer to be the same as the dhcp scope of the wireless network, communication and printing worked.
Problem solved. User error

2504 WLC on edge network for guest wifi

I have a 2504 WLC with a 1042 AP and I have it placed on my edge Cisco 3750 switch.
I have the management interface of the WLC set on my WAN IP 71.x.x.x subnet range, and I have the WLC doing DHCP duties with a DHCP scope of 192.168.X.0. I have my DNS servers set on external DNS servers out on the Internet.
I have two Cisco 3845 Routers on my edge network - one for each ISP with BGP protocol.
Since my native VLAN is 71.x.x.x, I added a sub interface on my main core router and gave it a 192.168.x.1 255.255.255.0 address for the gateway. Also, I added ip prefix-list iBGP seq 10 permit 192.168.x.0/24 le 32 to my main core router. On my secondary ISP router I added
ip prefix-list iBGP seq 10 permit 192.168.X.0/24 le 32, and ip prefix-list OUT seq 10 permit 192.168.x.0/24 statements.
I added VLAN 10 to my edge switch and gave it IP 192.168.x.2 255.255.255.0, and the switchports that my core router and my WLC are connected to the edge switch, are in trunk mode with encapsulation dot1q 10. The switchport on my edge switch that the AP is connected to is in switchport access mode.
I can connect to the wifi with a 192.168.x.x IP address on my laptop, but I cannot get any Internet access.
Is it possible to have the DHCP scope be in a different subnet than my WAN IP subnet, and allow guests to get to the external Internet only? Do I need to put the WLC somewhere internal on my network i.e. the DMZ and then tunnel the traffic out to the Internet with no Internal network access?
Thanks for any help you can provide.

right, and how does a 'normal/current' user access the internet? Somwhere going to your ISP there should be some sort of NAT statement when you send interwebs traffic.
if your ISP is taking care of all of that for you, you probably need to let them know you added the subnet so they can do the NAT.

Configuring 2504 WLC for LanSchool/AppleTV

Good Day to All,
Recently my small elementary schools have upgraded to Cisco Air-Cap2600 series AP's and a 2504 WLC. Very much a sweet step up from 10 year old Apple Airport Extremes.
My question is what would be the best pratice to enable Multicast via the GUI for the needs of those platforms and any other future P2P services?
Thanks in advance from a newbie,

Apple Devices on 2504 WLC with 5 APs

Hi All,
I have just setup 5 APs (1042) with a 2504 WLC, I have connected these devices in my home lab and will be deploying this later in a live environment. The WLC/APs will reside on the 192.168.210.x/24 subnet with the controller being on x.x.210.5 and the gateway (including the DHCP Server) being on x.x.210.1/24.
Here is my issue, I have configured my WLAN to use WPA+WPA2 with AES & TKIP using a Preshared Key but I am finding associating to the wireless network very slow on my Windows PC and, even worse, now connection from my iPad (I should mention the Windows PC is stable once connected).
I can see both devices seen by the APs when I look at the client list:

I am making sure that I do that , but still to no avail. I am going to mess about with the 'Global', 'Enabled', 'Disabled' parameters (in the Controller - Interface -DHCP Information section) to see if that makes any difference.

Port Configuration on new 2504 WLC

I've read some conflicting things on the new 2504 WLC's. Some things indicate all 4 ports are fully useable, while
others indicate perhaps only 1 or 2. I think I've read in product documentation that it support a max of two ap-manager interfaces. Does anyone know for sure if all 4 ports are useable? I'm thinking of the following configuration:
Port 1: management interface and first ap-manager interface
Port 2: second ap-manager interface
Port 3: first dynamic/client interface
Port 4: second dynamic/client interface
I'm planning on deploying my ap's in h-reap mode with a max of 25 ap's per 2504. Since I'm using h-reap, bandwidth shouldn't be much of an issue so I'm also considering trimming it down to using just two physical ports as follows so I can take up fewer gig switchports which are scarce at many of my locations:
Port 1: management interface and first ap-manager interface
Port 2: first and second dynamic/client interface
Opinions? I've always deployed 4400's and 5508's with LAG so I haven't had to think about this much until now.

Hi Evan,
For sure! There is a really good example on the configuration guide, and assciated caveats.
http://www.cisco.com/en/US/docs/wireless/controller/7.4/configuration/guides/consolidated/b_cg74_CONSOLIDATED_chapter_0100011.html
Benefits for using LAG is increased bandwidth, and redundancy - especially if you have the two (or more in the case of a 5508 WLC) ports connected to different physical switches, eg a 3750 stack.
Best,
Evan

Please help me to configure 2504 WLC as secondary in N+1 HA mode. My primary WLC is 5508 and both have 50 AP license.

Does a 2504 WLC support mobility group with WiSM1 on 6500 Series

if a 2504 WLC support mobility group with WiSM1 on 6500 Series.
Model: WLC 2504
Software version: 7.3.101.0
Model: WiSM1
Software verion: 7.x.x.x

Yes and no.
Yes, mobility is supported.
No because I personally won't recommend inter-controller roaming. This is more true when you're dealing with 4400/WiSM-1. This is even more true when you've got WLC running two (or more) different codes.

2504 WLC future LAG support?

We just bought a 2504 WLC with 15 AP licenses for our new eight 1141N AP installation. Some confusion about LAG support for these now confirmed by TAC that LAG NOT supported for the time being. Has anyone heard about whether this feature will be added to the 2504 in the future? Seems a waste of those four ports toherwise. Just wondering....

You can still utilize multiple links on the 2500 platform. If you create multiple interfaces with AP management enabled, you can load balance APs across the port(s).
Likewise, you can put your various wireless client vlans on different physical ports to avoid having ALL traffic on a specific port.

Will the 2504 WLC internal DHCP give IP addresses to clients?

Is there a way to configure the 2504 WLC so that its internal DHCP only services the LAPs?
I don't want the controller to give out IP addressed to wireless clients.
Thanks

No.
DHCP on the WLC is never intended to offer DHCP services to any "wired" side devices, which includes your APs. These DHCP pools are specifically to hand addresses out to wireless clients attached to WLANs of the specific WLC it is configured on. Even then, unless you absolutely cannot offer DHCP somewhere else, DHCP on the WLC is not a suggested practice.

What code editor do you use with Business Catalyst?

I am having many issues with Dreamweaver & BC:
1 - It keeps thinking that I have the trial version, even though I have a license to Creative Cloud and Creative Cloud shows that I have it.
2 - When I try to use the integrated Business Catalyst palette, it logs me out of the admin console for my BC site. ANNOYING.
3 - Most importantly, it doesn't put the files to the server successfully, consistently. I have change my file and re-put the file 5-6 times before it works. VERY FRUSTRATING!
After an hour on the phone with Dreamweaver customer support, the issue is still not resolved.
So, now I ask you all, what code editor are you using in conjunction with Business Catalyst while implementing your Business Catalyst websites?

Code editors, I used to use editplus until Adobe locked 90% of the FTP programs out there, now I use Sublime 2 with SFTP plugin but it's uber clunky and not so happy with it...

Hi Nishu,
There is no way you can validate the fields and their lengths before you ipload them into internal tables.
First you should upload them and then loop the intrenal table to delete such records.
loop at itab.
if strlen(itab-comp_code) < 4.
delete itab index sy-tabix.
endif.
endloop.
