AIR-CT2504-HA-K9 N+1 redundancy config

Hi Experts,
After I read some documentation it is still not 100% clear for me what are the procedure to configure additional WLC controller we bought (
AIR-CT2504-HA-K9). What we need to achieve is just the basic N+1 redundancy. We have our existing WLC 2504 and 15 LAPs 1262.
Please advise if these steps are correct:
1. Backup existing config from primary WLC.
2. Upgrade backup WLC to the same OS version
3. Upload config to the backup WLC
4. Change all IPs - it should be different but on the same subnet as the primary one.
5. On the primary controller change AP redundancy settings - add IP of the backup controller.
6. Plug backup controller to the network and test failover by disconnecting the primary one from the network - after 2 minutes all APs should reconnect to the backup one.
7. If all good disconnect backup one from the network and all APs should fall back to the primary one.
Thanks in advance.
Regards,
Gleb.

Thanks for this Scott,
additionally do I always need to update the config on the backup manually as long as there are some changes on the primary one?
not sure what this means as well, do I need to go through this step (figure 2.8):
An HA-SKU secondary controller can also be used as a primary, secondary, or tertiary controller. This
can be configured under the AP specific configuration.
Thanks in advance.

Anyone got the AIR-CT2504-HA-K9 to work on N+1 Redundancy ?

Hi Guys,
Seems like the new Part #AIR-CT2504-HA-K9 needs some kinda licensing...to work... otherwise the redundancy is same as it was ealier with mobility groups.
The documentation seems to be wrong in the case of 2504, i cannot find the redundancy button in the Wireless tab too, When i apply the Evaluation license redundancy is working.... did anyone else face the same Issue ?
Regards,
Vinu

i cannot find the redundancy button in the Wireless tab too
You mean AP SSO?
WLC 2500 will not support this feature.

AIR-CT2504-50-K9 with out DHCP Static config

We have AIR-CT2504-50-K9 and AIR-CAP1602I-TK910 30 devices we want config trough controller to AP with out DHCP

#Yes, you can use internal dhcp server on WLC-2500 to lease IPs to the connected APs using L2/Broadcast, once AP gets an ip then you can make those IPs as static on those APs via check box from AP's general tab after it joins the WLC.
#Remeber, WLC dhcp doesn't support option 43, if the AP and WLC management are L3, be sure to use ip-helper at L3 for wlc discovery. Also, don't think AP may receive ip from WLC dhcp server when it is L3 and dhcp proxy is used instead of broadcast.

Yes. You can configure them individually.

One WLC AIR-CT2504-K9 for Main office and 3 Branches

Hi ,
I need to configure a WLC AIR-CT2504-K9 with the followings requiremets:
1.- There is a main officce where the WLC and 7 LAPs will be installed.
2.- There are 3 branches; one LAPs in every branch will be installed.
3.- SSIDs for internal users and guest will be the same in each office.
Is it possible to set this scenario ?? (see complete info in table)
In the past I configure some WLC 2100 but I noticed some difference with this new WLC-CT2504
one of the differences that kept my attention were regarding ap-manager interface (not shown)
and virtual interface ( shown as NOT SUPPORTED)
Should I set ap-manager interface or is enough with managment interface ?
why the message "Not support" in virtual interface ??
How can I use one port for two interfaces (as is proposed in table), if I try to do this a message error is displayed
"Error setting AP Manager interface".
iF I set one interface and associate to one port (Enable) I can not set second interface in the same port so remains disable
This model of WLC just has 4 Ports.
I have read last config guide but is not clear for me because there is no examples of this kind of scenario.

Hi Scott,
I configured virtual interface from startup configuration wizard.
(Cisco Controller) >show interface detailed virtual
Interface Name................................... virtual
MAC Address...................................... d0:c2:82:e3:8e:c1
IP Address....................................... 1.1.1.1
DHCP Option 82................................... Disabled

AP Manager....................................... No
Guest Interface.................................. No

AIR-CT2504-25-K9 (HA) Help needed

Hi all,
I got two AIR-CT2404-25-K9 and i need them in HA (Active/Passive) i would like to add a AIR-CT2504-HA-K9 but can someone tell me if i need one or two for an active/passive config.
Thanks for your help!

2504 just does N+1 HA from 7.5, whereas the bigger platforms do AP SSO and Client SSO. And obviously , you need 2 AIR-CT2404-25-K9 for HA.

Ports on AIR-CT2504-5-K9

AIR-CT2504-5-K9 has 4 Gig ports with a note "Access point directly connected to the controller is not currently supported."
So what is the idea for these ports? Just an etherchannel to provide 4 Gig of bandwidth or some other uses?

Hello,
The ports on the 2500 can be used for multiple deployment scenarios. You can have port 2 be a backup port in case the connection on port 1 fails (redundancy). You can also send different vlan traffic out a different physical port (guest segment, etc). The 2500 does not support Link Aggregation, so you cannot configure the ports in an etherchannel bundle.
At this time, connecting APs directly to the WLC is not a supported scenario.
For additional details, please see the following section of the 2500 deployment guide:

AIR-CT2504-5-K9 capacity adder license error

Hi, i have AIR-CT2504-5-K9, with 5 access point license support. I buy capacity adder license LIC-CT2504-5A for add 5 access points more. When i try download licence file from tftp server on WLC system i see message "License 1 Failed 1" on WLC. TFTP server message downloading OK.
In what could be the problem?

As far as I'm aware, the 2500 can support 5, 15, 25, 50 or 75 APs. And here's where logic does not apply: So if you have WLC with 5 AP, the next adder license you can get is 15. If you need more, you need to get 25. And that's it.
So all in all, if you have a WLC with 5 APs, the highest you can get is 45 AP support. You cannot get another 25 adder license.
This is how it works. I know it doesn't make sense. I don't make the rules.
NOTE: One guy, George, was able to do something about this. He RMA-ed his WLC and they gave him the same model but modified some stuff that he was able to get the maximum.

AIR-CT2504-5-K9 data encryption

All,
I am looking important info , I am going to order AIR-CT2504-5-K9 WLC . with software AIR-CT2504-SW-7.6.
1) would like to check the image AIR-CT2504-SW-7.6 has a inbuilt DTLS ( datagram transport layer security ) ?? . like in WLC 5500 series the image SWC5500K9-74 DTLS (Datagram Transport Layer Security) for encrypting CAPWAP data packets is enabled in this image.
2) on the AIR-CT2504-5-K9 , shall I need to order additionally 2504 Data DTLS License LIC-CT25-DTLS-K9 ?
please let me know
Regards
Lerner

As long as they ship you a 2504 that doesn't have the LDPE software version, or else you will have to obtain the free DTLS license and convert the image to a non-LDPE code.

Question about RPS2300 and 'redundancy" config on IOS router

We have a 2951 router connected to an RPS2300 remote power supply. On the router there are two commands applied in global config mode, "redundancy inter-device" and "redundancy". The engineer who set up the router originally states that these commands are necessary for the RPS2300 to work properly with the 2951, but the documentation for the "redundancy inter-device" and "redundancy" commands do not seem to be related to the RPS at all. Can anyone tell me if either of these commands are required for RPS, or if there is any other config that must be added to the 2951 for the RPS2300 to function properly?
An excerpt from the 2951 config:
vtp mode transparent
username <detail removed>
username <detail removed>
redundancy inter-device
redundancy
controller T1 0/0/0
As you can see, there is no additional configuration under either of the "redundancy" commands.
Thanks
-Mat

To clarify, the 2951 router has an RPS-ADPTR-2921-51 module installed which connects to the RPS2300 unit.

Macbook Air vs Macbook Pro w/Retina after config

Hello,
I'm interested in a laptop for basic needs: email, surfing the web, music, word processing, quick load time for programs, multiple windows open at once. Taking into consideration that configuration options can be the same for both (below is what I interested in getting), would it be better to go with the Macbook Air vs the Macbook Pro w/Retina since it has better battery life? I'd like this laptop to last for 2-3 years before I would get a new one. The prices were pretty close so I would need another deciding factor. Is the screen resolution enough of a difference to go with the retina? Thank you!
Macbook air 1-7, 8gb, 512GB PCIe-based Flash Storage
Macbook pro w/retina display, 1-7, 8gb, 512GB PCIe-based Flash Storage
Best,
Lindsay

The basic requirements that you listed will be well within the capabilities of both machines. The AIR has dramatically superior battery run time and is slightly easier to transport. The retina has a superior display. Go to an Apple store and look at both. That is the best way to decide.
Ciao.

AIR-CT2504-5-K9 Expansion

Hello,
I would like advised over this matter.
I have a WC 2504 with 3 AIR-LAP1141N-A-K9 APs. The network clients have increased by 90 wireless devices, and we are experiencing a noticeable drop in speed a peak time when all devices are connected. We are planing to add another AP. So far, we are using a Dual VPN Router to share internet network load at 100mbps/25mbps and 15mbps/5mbps.
Do we have to use the same AP model (in this case AIR-LAP1141) or can we use another AP model to balance the network load?.
Thank you very much for sharing your experience.
Respectfully.
Rudy Rodas

Hi Rudy,
You do not want to go with same AP model.
I prefer you go ahead with a dual band (1600/2600/3600) AP model rather single band like you have at the moment.
Refer this for the WLC software compatibility with these AP models

AIR-CT2504-5-K9

Is it a new WC or I missed it before? What is the price?
I am looking what are my options to set a wireless lab, have two 1242AG APs already and controller would be nice but prices are steep even for entry point (like most Cisco).
http://www.cisco.com/en/US/prod/collateral/wireless/ps6302/ps8322/ps11630/data_sheet_c78-645111.html

The cheapest 2106 which I can find is around $1k. Could you at least give me an idea if this thing new is priced higher or lower then 2106?
No I won't. There are so many things a 2100 can do that a wlc 2000 just can't/won't. You know somethings not right when the 2000 was quickly superseded. Sorry mate, I ain't going to recommend something that I personally won't use.
Do both, 2106 and 2504 have the same functionality?
Define "functionality". If you mean very simple, wireless here and there they do have the same functionality. If you want to go down the road of, for example, OfficeExtend then the this feature is only supported on the 2500/5500/WiSM-2.
I will never go over 5 APs so basic license looks more then enough in my case.There's only one feature license. The "license" in question is the number of AP the WLC can support. This is easily upgradable as your business requirements grow.
Do both support a network extension (Cisco 600)?
The new AP600 is supported on the 2500/5500/WiSM-2 only.
This 2504 is actually a bit strange product. Has 4 Gig interfaces but none are PoE and there is even a note
Never has and never will. Don't know with you but I don't agree with PoE and WLC in a box. This is because most deployment has the APs connected to a (PoE) switch.

WLC: AIR-CT2504-50-K9 Vs HP J9420A

Helloooo
I need to show the best in Cisco controller versus HP (HP MSM760 Mobility Controller) controller in point of Security and mobility and other
difference will make choosing Cisco WLC as a piece of cake.
So your help is needed, please

Salam Samer,
I have no idea about the HP product itself. But you can always check the datasheet of the product (2500 WLC) and compare the specs with the HP one.
Here is the datasheet of the 2500 WLC: http://goo.gl/dSLZbp
The price is not mentioned in the datasheet. That can be a basic element to decide the product sometimes.
