5508-12 HA Licensing

Hello can the 5508-12 be converted into a standby HA controller? Cisco is abiguously saying that 50 permanent licenses are needed on a standby controller.
Does it mean we need 50 base licences (so only 5508-50 and above) or 50 licenses as any combination of base + adder licences?
Thanks!

There are two things, to add another controller in HA,
1. Either the controller which is assuming the role of Secondary got Permanent AP count license
or,
2. buy a HA SKU controller License for a controller which has got no other license.

5508 HA pair licenses

I have 2 5508 that are currently running as active with 150 licenses each. I want to go to HA SSO can 100 of the licenses be relicensed to the primary since it only requires 50 licenses to convert an active license 5508 to standby HA SSO?

So are you saying if the 5508's were purchased with 100 each and a 50 adder license was added to each the 50 could possibly get rehosted from what will be the standby to the soon to be primary?
Thanks for your response

5508 reboot lose License

I have WLC 5508(version7.4) and 50 AP-Licenses. When reboot the WLC, the AP-License will be lose.
I have to import the license file with tftp again(although the WLC will remind the file already exists).

Hi
Yes,I save the configurations.
Actually,the WLC have 12 AP lic before,and have a 50 AP lic upgrade. when reboot the WLC
12AP lic is exist, but 50AP lic is gone.
After installing the lic the first time reboot, lic is exist,but the next time reboot the lic is gone.

Low Bandwith, WLC 5508 and LAP 1142N, please help !

Hello Everyone
For the Environment:
- I have a WLC 5508 With a license up to 100 AP, at the Point there are 39 AP connected.
- The WLC is connected with 8x 1Gbit/s, as a Trunk ==> 2 Members of 3750 Switches Stack ( 4gig and 4 gig)
- The AP are connected to diferent 2960s with an Uplink ( 3 Gbit/s) to the 3750 Switches
- There are max. 12 AP on each 2960s
- The AP are powered over Ethernet
The AP:
- it runs a/b/g/n and on 2,4 Ghz i schould have 300 mbit/s as for the 5 Ghz it schould also run 300mbit /s
- the Ap has an uplink of 1 Gbit/s
The clients:
- have a intel Wifi link 5300 AGN Card
To the Problem:
- if i connect to one AP, and the Signal strength is High, i get an upload rate of max. 6-8Mbyte/s.
and i am the only Person uploading.
if i upload from 3 clients the same data from the same spot to the same target i get 2-3 Mbyte/s per client.
if connect to the same target and run over ethernet cable fom the same spot, i get an upload of 70 -85 Mbyte/s.
Question:
- Why am i having these Bandwith problems ??

Thanks Scott,
I understand what you are mentioning, and i really didnt do it yet.
I realize that the primary controller was not configured on the

Is this mandatory for a 1 controller only ?
No mather what the manual say, after that the AP is rebooting 2 mins in 2 mins... with the same kind of messages.
The interface on the switch is getting a few input errors and the same numbers of crc... but are so few...

HA with WLC5508 and licenses

Hello.
We are currently running our wifi with a WLC5508 with a base license for 100 APs, a NCS and about 90 APs.
Now are wifi is growing and we will need more than 100 APs shortly. When I checked the prices I found that a new 5508 for 100 APs isn't that much more expensive than an add on license and it would be great to have some redundancy. If I use two 5508's with license for 100 APs, what will happen if one of them fails and all APs connect to the single 5008? Is there a way to use both licenses for a single 5508 in the case that one of them goes offline?
Bonus question: What happens when the NCS database grows to big for its disk space (running as virtual appliance)? Will it start to delete the oldest entries in the database or will it fail in some way?

Response for the Bonus Question:
If the NCS database grows too big for the disk space allocated, data will be deleted only according to the data retention settings under Administration>System Settings and will eventually crash if an additional virtual disk isn't added. Keep in mind this warning starts popping up when the utilization on any of it's volumes goes above 60% so you probably have a little time.
Check Administration> Appliance to see which volume is above that threshold. It could actually be the localdisk volume causing the alert and not the database.
Adding additional disk space to Prime Infrastructure is as easy as doing an ncs stop, powering down the VM, adding a new virtual disk (NOT increasing the size of original disk), then powering the VM back on.
To add additional disk space to NCS the TAC has a disk grow script that has to be executed once the additional virtual disk is added or you'll never see the volume increase once you power the VM back on after adding the additional drive.

WLC HA SKU Licensing Issue!!!!

Hi Team,
We have received HA SKU WLC 5508 with no License. As per Cisco Documentation, by default HA SKU Standby WLC will be working as an Redundant WLC instead of Load-Balancing + Redundant WLC.
During the Primary WLC failure, the Standby WLC will retain its Role and here, the 90 Days timer will start.
Now, our doubt is, once the Primary WLC is up, what will happen to 90 Days Timer, will it reset?
Regards,
YSR

Hi,
Thanks for the Information but still we have couple of doubts:
What do you mean by New WLC, is it Primary WLC?
What does AP Count mean here?
Are you considering "Fail-over scenario where WLC restarts" or considering the "Fail-over scenario where WLC is having Hardware Problem and need to be replaced".
We have gone through the Cisco Document and because of these doubts, our implementation has been stuck.
Regards,
YSR.

Upgrade to WLAN 5508

Does anyone know if there is an upgrade path from the WLAN 4402 to WLAN 5508? OR A proceedure to get the AP's to join the new WLAN?
We currently are using a WLAN 4402-50 and have maxed it out. We are plannning on purchasing a 5508 with 250 licenses, but we have AP's in remote locations using HREAP and it would be very costly to re-visit each site.

In the WLC 4400, go to All APs and click Details. Choose the AP of your choice and go to High Availability. Put the information of the WLC 5508 and click apply.
Alternatively, if you are tired of doing this on a per-AP basis you can go to Wireless > Access Points > Radios > Global Configuration. Under High Availability enter the information of the WLC 5508 and click apply.

Query regarding Mobility configuration

Hi All,
I have some queries regarding mobility configuration. I have to two WLC's; one Cisco 5508 & another Cisco 4402. My queries are:
1. I have configured both the WLC's in same Mobility domain & same Mobility group but with different Management IP segment. Will they be considered within the same mobility group or they will work as if they are the part of different mobility group?
2. Currently I have 100 AP license on WLC 5508 & 50 AP license on 4402. I am having more than 50 AP's in my network & all are registered with WLC 5508 since it is the primary. I want only selected 50 AP's to register with WLC 4402 in case WLC 5508 goes down. Is there any way I can achieve this?
Regards,
Shahab

1. I have configured both the WLC's in same Mobility domain & same Mobility group but with different Management IP segment. Will they be considered within the same mobility group or they will work as if they are the part of different mobility group?
Yes... As long as there is connectivity between the two WLC and the ports udp 16666 and IP97, the mobility should be up.
2. Currently I have 100 AP license on WLC 5508 & 50 AP license on 4402. I am having more than 50 AP's in my network & all are registered with WLC 5508 since it is the primary. I want only selected 50 AP's to register with WLC 4402 in case WLC 5508 goes down. Is there any way I can achieve this?
Depending on the code in the WLC, you can set the priority to the AP in the high availability. So the 50 AP's you can set them higher than the other 5.

WLC 7.3 and HA

case :
1x 5508 112 ap license
1x 5508 HA sku
http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bd3504.shtml#combo1
what does mean:
With the new WLC coming up, HA SKU at the time of paring will get the AP Count:
If the new WLC has a higher AP count than the previous, the 90-day counter is reset.
If the new WLC has a lower AP count than the previous, the 90-day counter is not reset.
After switchover to a lower AP count, the WLC offset timer will continue and nagging messages will be displayed after time expiry.
in particular what "an higher AP count than the previous" means?
after switchover to primary restored wlc (112 licence) the counter is not reset and buying new licences for primary is needed?
and the difference between HA sku and 50 ap licence for the standby?
thank you

the 21xx does not have a physical license for the number of APs, it is controlled by hardware. Only the 5508 has a license that needs to be installed. So you should be good to upgrade to 7.0.

Please refer to the below points esp. highlighted sections ( taken from link posted by Leo ) , it completely answers your query:
Configure one WLC as Primary (by default, the WLC HA Unit ID is Primary and should have a valid AP-BASE count license installed) and another WLC as Secondary (AP base count from the Primary WLC will be inherited by this unit) using the CLI in this step. In this example, WLC 1 is configured as Primary, and WLC 2 is configured as Secondary:
You do not need to configure the unit as Secondary if it is a factory ordered HA SKU that can be ordered from release 7.3 onwards. A factory ordered HA SKU is a default Secondary unit, and will take the role of the Standby WLC the first time it is paired with an Active WLC that has a valid AP Count License.
If you want to convert any existing WLC as a Standby WLC, do so using the config redundancy unit secondary command in the CLI. This CLI command will only work if the WLC which is intended to work as Standby has some number of permanent license count. This condition is only valid for the 5500 WLC, where a minimum of 50 AP Permanent licenses are needed to be converted to Standby. There is no restriction for other WLCs such as the WiSM2, 7500, and 8500.

Single Corporate SSID + Single Guest SSID across 200 sites over VPN with Flex Connect

We have two main sites (East Building as DR + West Building as BDR) + 100 remote sites / all connection between the sites based on VPN / OSPF
East building has 1 WLC 5508 with a license of 500 AP
West building has 1 WLC 5508 with a license of 500 AP
50 remote sites in East
Each East remote site have 5 AP (AIR-LAP1142N + AIR-CAP2602I)
Total AP in all the 50 remote site in East is 250 AP
50 remote site in West
Each West remote site have 5 AP (AIR-LAP1142N + AIR-CAP2602I)
Total AP in all the 50 remote site in West is 250 AP
Hardware available are:
2 * WLC 5508
2 * ACS 5.2
Most of the switches that connect to the AP are 2960G
All the AP are
AIR-LAP1142N-E-K9
AIR-CAP2602I-E-K9
Requirements in Brief:-
1 SSID for Internal user across all the sites
1 SSID for Guest user across all the sites
All IP for all the sites based on their local subnet
All the remote sites need to be Flex connect
The 2 WLC need to configure as failover
Requirements in Details:-
One Corporate ABC-SSID for all the sites
One Guest ABC-SSID for all the sites
The WLC in East building is the primary which control all the East remote site (250 AP)
The WLC in West building is the secondary which control all the West remote site (250 AP)
A fail over between the two WLC as below:
If the WLC in east fail then all the AP in east (250 AP) will connect to WLC in West
If the WLC in West fail then all the AP in west (250 AP) will connect to WLC in East
Each Remote site behaving as Flex connect to reduce the overhead over the WAN/VPN
Each site must have their own AP groups for the ease of management
All the AP MGMT IP based on their local subnet
Each remote site, West building, and East building must obtain their IP based on their local VLAN Example:- site-1 in East:
Corporate ABC-SSID take 10.204.0.0/24
Guest ABC-SSID take 192.168.0.0/24
Example:- site-2 in East:
Corporate ABC-SSID take 10.204.1.0/24
Guest ABC-SSID take 192.168.1.0/24
Example:- site-3 in East:
Corporate ABC-SSID take 10.204.2/24
Guest ABC-SSID take 192.168.2.0/24
And so on…….
Example:- site-1 in West:
Corporate ABC-SSID take 10.204.100.0/24
Guest ABC-SSID take 192.168.100.0/24
Example:- site-2 in West:
Corporate ABC-SSID take 10.204.101.0/24
Guest ABC-SSID take 192.168.101.0/24
Example:- site-3 in West:
Corporate ABC-SSID take 10.204.102.0/24
Guest ABC-SSID take 192.168.102.0/24

Expert I'm really stuck here, so please any help will do.
Thanks in advance

What are you stuck on? What you have mentioned is possible.
When you setup FlexConnect and also when AP's night failover, you need to make sure that the WLAN ID are in the same order in bother WLC's. also the AP Groups have the same information and have the same AP Group names and WLAN to vlan mapping. So as long as the WLC's are configured exactly the same except for IP addresses and hostname a, failover for FlexConnect will work fine.
Now the FlexConnect WLAN to vlan mapping is done on the access point itself. So each AP will have to configured. AP Groups will not help here as you can really just create one since you will have the same WLAN's broadcasting at each site. You can make is simple though:) and this is a good tip.....
If all your vlans are the same in every site including your DR and BDR, then the WLAN to vlan mapping will use the vlan if you have specified in the the WLAN under the I terrace mapping. So if in your corporate WLAN it is mapped to I terrace vlan 100, all you FlexConnect AP's will have that mapping set to vlan 100. If your guest at WLAN is mapped to vlan 999 interface on the WLC then the FlexConnect WLAN to vlan mapping for the guest will be set to vlan 999.
Now if you have different vlan id's for each site or it might be the same for some and not the others, well you will have to tough each AP and configure the WLAN to vlan mapping.
The WLAN to vlan mapping appears only when you have enabled FlexConnect local swit hung in the WLAN and you have the access point in FlexConnect mode.

To 3850 or not to 3850?

Currently I have two 5508 controllers each licensed for 100 AP's configured in a 1+N setup with a total of 100 AP's between the two controllers. (50 each).
I am going to add AP's in two remote buildings that are each connected to the core (where the 5508's are located) via a 20Mb TLS circuit. I was thinking of just adding more license to the 5508's and having all the new remote AP's just connect back to the existing 5508's. Keep in mind that all services are located at the core so anybody that connects to the wireless in the remote buildings will be accessing services in the core.
I have been doing a lot of reading about the new 3850's and I see the benefit of the CA and having the AP's terminate locally but in my case would it make sense to do that?
As I understand it I would have to have a 3850 in every closet where an AP comes back to as they have to be directly connected? So this would mean that I would have to upgrade my network closets to all new switches.
The total number of AP's after all remote sites are done will be about 250 so I could still provide the 1+N relationship with the two 5508's.
Thank you for the input.

//Absolutely, Yes.
With 3850 deployment, You can still make use of AP licenses from 5500, However you need to purchase more 3850s since AP has to be directly connected to the 3850.
