2100 WLC Redundent LAN Uplinks?

Hi,
In the data sheet for the 2100 it states that "Provides eight 10/100 Ethernet ports, intended to support a combination of access points and redundant LAN uplinks"
http://www.cisco.com/en/US/prod/collateral/wireless/ps6302/ps8322/ps7206/ps7221/product_data_sheet0900aecd805aaab9.html
My question is.. How do you configure the redundent uplinks as aparently the 2100 doesnt support LAG (Link aggregation)..
Any ideas?
Many Thanks

Excellent, Thanks.
So i can uplink the primary and backup ports to seperate switches?
I'm thinking that i would home all interfaces to the same priamry and backup ports and then uplink each port to a different switch. There isnt really a need to try and load balance as the traffic volumes are quite low.
What do you think?

1041N APs not joining 2100 WLC

Hopefully this will be an easy solution for some of you.
I have two LAP1041N APs I am trying to setup on a new 2100 WLC (7.0.116.0). THe APs will blink green fast; then go to a green, red, blue cycle for a min or so; then back to blinking green fast. Not sure what else to try here.
Thanks for the help.

Please use a L2/ L3 switch
For a L2 swith the AP and WLC must be on the same VLAN iof the L2 switch
For AP:
config t
int gig 0/1
swithport access native vlan 1( for ex)
switchport mode access
no shut
For WLC :
config t
int gig 0/2
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk native vlan 1
no shut
For L3 switch you can assign vlan interfaces :

WLC Redundancy Question

Hi Community,
I have one question regarding the redundancy feature for two WLC 2106. We have installed on a customer site 2 WLC's 2106 and 6 AP's. Primary and Backup WLC works fine. No the customer asks the question if there is a option to copy the guest access wlan user from the primary controller to the backup controller? The lobby user activates a new user on the primary controller and if the primary controller fails, then the user did not get access to the wlan guest network.
Any ideas?
Thanks for help.

Hi Jerry,
Mobility - it's used for client so that they can roam without any issue and one tunnle will be stablish between wlc-1 and wlc-2. if wlc-1 goes down the client will be local to the wlc-2 and if the guest user is not present on wlc-2 then it will not be able to access network.
HA for AP - primary, secondary are used to achieve this.
HA for WLC (WLC redundency) - suppose you have two WLCs if one goes down then second will start serving without any issue. For that master wlc will push all the config to second wlc and some other mechanism to achieve this. This functionality is not yet support.

WLC Redundancy over L3 link

Hi All,
Is it possible to deploy WLC redundancy over L3 link???
In our scenario we have 2 controllers located in 2 different sites, the link between the site is L3. AP's are deployed across four other locations, two are coming to site 1 and rest two are coming to site 2 . How can i make redundancy on this setup , Please advice
Controller is 4404 and AP's are 1231G series .
Regards
Aslam ...

What is your link between each site? Also, I suppose your ap's are running in H-REAP mode? If you don't have enough bandwidth, then you shouldn't try it. You can always try to move the ap's to either wlc and see if users have any issues or not, before you try to deploy redundancy in this matter.

2100 WLC 1130 APs - need some help please

It's been about 5 years since I took my CCNA course and could use some help on a wireless set up for church.
We have a Catalyst 3550 that is running fine, just a few VLANs, including 30 for public wireless. I've then got a 2100 WLC and (3) 1130 AP's. After much head banging, I've got the WLC set up correctly (i believe)
VLAN 30 is a 10.0.3.x segment
switch is 10.0.3.1
WLC mgmt interface is 10.0.3.20 - connected to the switch on port 1
WLC ap mgmt interface is 10.0.3.21
APs pull 10.0.3.30, 31,32. - they are plugged directly into the switch
I can obviously see the APs while in the WLC GUI.
The AP's SSID don't show up wirelessly. The AP's circle is red/orange
The detail on the AP in the WLC shows them operationally down.
What additional information can I provide?
Much thanks.

2100 WLC help

Hi, i was tasked with moving two 2100 WLC from one switch to another. Before the move both switches saw 11 APs. supposedly they were configured if one 2100 fails the other takes over. Now i have moved both to a new switch and both are pingable and the config look identical however one of the 2100 controller stopped seeing the APs.
My question is should both WLC see the APs, also the master controller mode box is not checked for any of the WLC. Again both were seeing the APs now only one is. My experience with the 2100 is limited.
thanks for any help
paul

Only the WLC that has the AP should see them. The WLC only sees the AP that are joined to them.
As for Master Controller Mode, that only comes to play if the AP do not have a Primary/Secondary WLC set. And that setting does not survive a reboot.
HTH,
Steve

WLC 2100 series Guest LAN not found

Hi there
I am unable to configure Guest LAN as in this link
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00808ed026.shtml
because my Cisco WLC 2112 version 7.0.240.0 does not have the option for Guest LAN. Is Guest LAN supported for WLC 2100 series? Any workarounds or suggestions?
Thanks for your help
DIego

Diego,
Wired guest access is not supported on WLC2106.
Reference:
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00808ed026.shtml#configs

5508 WLC redundancy issue.

I am trying to set up fail-over for Cisco 5508 Wireless LAN Controller which is using 7.4 version software. I setup the redundancy port and peer redundancy.
While checking,one becomes active and other becomes standby.
Its showing everything perfectly including peer,standby-hot etc.(XMLs matched also)
I disconnect the 1st WLC uplink and then the Stand by becomes active. Fine.
Later i connected the 1st WLC link and disconnect the 2nd WLC (currently active). Here comes the issue.
Then other WLC is not becoming Active and it enters in to Maintenance mode. Means Down.
why this issue happens?
One thing i need to highlight is, one WLC is having 50 AP basce license count and other WLC having 250 AP base license count.
Is this will be an issue? Whether the License count should be same on both?
If so,how can i trim-down 250 to 50 AP base license?
Any clues? Help me!

You don't have trim down the license. The license amount is going to be what you have on the primary. As far as failover the way your doing it, I don't thinkers supported that way. Only a hard failure. So you will have to manually switch the primary back.

WLC Redundancy after RMA

Hi,
after an RMA i installed a new WLC 5508.
Now i want to pair the new controller with the old one to the HA mode.
The Controllers are in SSO mode.
IP Adressing of both controllers are ok but the Mobility MAC Adress on the new Controller is not right and i can't change it.
How can i pair the both Controllers via CLI or GUI?

You have the flexibility to configure a custom MAC address as Mobility MAC instead of using the default behavior of using the Active WLC MAC address as Mobility MAC. This can be done using the configure redundancy mobilitymac <custom mac address> command on the Active WLC. Once configured, you should use this MAC address on other controllers in order to form a mobility peer instead of using the Active WLC MAC address. This MAC address should be configured before forming the HA pair. Once the HA pair is formed, the Mobility MAC cannot be changed or edited.

WLC redundancy with prime

Hi all,
We are going to implement high availabilty in 5508 WLC with version of 7.3.101 . We will be using Prime infrastructure 1.2 for monitoring purpose.
With Prime , whether we can monitor and manage redundant WLC also or only active WLC?...
Thanks for your help.......

I just know from experience. You can only GUI/ssh into the primary WLC when you enable AP-SSO. So once the pairs are in HA, that is it.... You have only the primary WLC IP address available. You learn things the hard way sometimes because there are things not documented.

WLC Redundancy - Regional / Centralised model

Hi all,
Our organisation has multiple controllers at regional sites (one per region) & want to implement redundancy by placing one controller at headquarter's datacentre as a backup in case the site's failed.
All our controllers are 5508 with 7.0.116.0 loaded
I did a search around and found multiple documentations of how to do it but all related to creating a mobility group
Is it possbile to implement this scenario without creating mobility group ? (As in Cisco docs for software release 7.0 June 2010 - quoted
"Centralized and regional controllers do not need to be in the same mobility group" )
I did try around but couldn't make it work ? Have anyone experience with this setup & give me some hints please?
Thank you,

Lam Hung Chung,
You can configure an access point to have a preference, in order, for up to 3 controllers. When the AP boots it will use these configured preferences to find a controller.
If you configure the AP's preferred Primary Controller as the local (regional) controller and the preferred Secondary Controller as the headquarters then when the regional controller is not available the AP will try to register to the headquarters controller.
You can configure this on an AP-by-AP basis, but this can be cumbersome and slow. If you have WCS or NCS, then you can use AP Templates to apply these changes on a site-by-site basis (by selecting multiple APs at a time), which will save you a lot of time.
Here is a screenshot for doing this manually on each AP:
Choose the Wireless tab on the top menu bar
Choose All APs under Access Points in the left nav window
Select the AP to be modified
Choose the High Availability tab
Enter your Primary and Secondary controller Names and Management IP Addresses

WLC Redundancy

Hello,
I have 2x WLC 5508 running version 7.2
1st one is setup and running.
My questions is: If I want to setup Active-Passive redundacy, do I need to manually setup the 2nd one exactly as the 1st one and put them in the same group?
Or is it a way to copy all of the configs I made on the 1st one over to the 2nd one?
Thank you.

I would setup the first WLC and then do a config backup via TFTP or FTP. Once you have that config backed up you can then apply it to the second WLC. From here you will need to change the IP and WLC name of the second WLC so it doesn't conflict with the first.
Also, if you want it to be a true Active-Passive then you will want to make sure that all of your APs are configured with primary and secondary controllers.

Multiple WLC redundancy using flexconnect across multiple branches.

Hi
I'm wondering if someone could give me a hint please.
I have two WLC 5508s in two different branches/countries.
They have APs configured as Flexconnect with local routing.
However all the APs are only on the first controller as the controller IP was manually entered before deployment.
(I'm guessing this will need to be changed to DNS resolution?)
1. I would like to load balance APs that are in more contries/branches across Europe between the two WLCs
2. and/or if one of the controllers go down, the APs would automatically move onto the other one.
I'm just not sure if both can be done if the APs are on flexconnect.
Thanks in advance for any replies.

Hi,
1. I would like to load balance APs that are in more contries/branches across Europe between the two WLCs
It can work, If you have configured the both WLC with excatly same way(same wlan id, same wlan name.....etc)
2. and/or if one of the controllers go down, the APs would automatically move onto the other one.
If the configuration for both wlc is same then primary fails then secondary will take place. Make sure WLAN ID order has to be consistent.
Regards

WLC redundency

Hello I have 2 WLC: a 2504 and a 5508, can one be the backup of the other?
How do i configure such settings?
I want a automatic backup when 1 is down (the primary would be the 5508) it will switch automaticly to the2504?
Thanx for your advice.
B

Just another questions not very important but still:
Is it possible to change all APs in 1 shot? instead of 1 by 1?
in the version 7.0.x i have a HA settings in Wireless,Access Points, Radio, Global Configuration.
Can someone explain me what it is for, there is the following field:
AP Heartbeat Timeout(1-30)
Local Mode AP Fast Heartbeat Timer State
Disable Enable
Local Mode AP Fast Heartbeat Timeout(1 to 10)
H-REAP Mode AP Fast Heartbeat Timer State
Disable Enable
H-REAP Mode AP Fast Heartbeat Timeout(1 to 10)
AP Primary Discovery Timeout(30 to 3600)
Back-up Primary Controller IP Address
Back-up Primary Controller name
Back-up Secondary Controller IP Address
Back-up Secondary Controller name
Tx a lot for the answer.

WLC Redundancy - Disaster Recovery

My questions is in relation to disaster recovery, for wireless. We have our main data center, in the US, with two 5508 controllers. We have a DR location, in Europe, with two 5508 controller. We're upgrading our 5508's to the 7.4 code, so that we can take advantage of the RP port for our controllers. With that said, is there a way to make the US and Europe controllers redundant? If there's a disaster, in the US, would the AP licensing, and AP's attach to the European controllers? Our AP's are set up with HA. I'm more concerned about the licensing flipping over to the DR controllers. I've tried researching this topic, and can't really find anything on it. Thanks!

If you can't use the RP port and configure SSO, then yes you need to have adequate licensing to support all the AP.
But if the AP fall from one DC to another, are the clients going to get the same IP? Failing across DC is most effective when you use FlexConnect, IMHO.
HTH,
Steve
