Cisco :: 5508 - NCS Configuration Backup And Restore Of WLC
Jan 10, 2012
I recently tested the process for a customer of defaulting a Cisco WLC to factory configuration and then restoring the configuration from Cisco NCS. It was not seamless to say the least and I wonder if I have just gone about it the wrong way.
Have have set the NCS platform to configuration sync with the 5508 controllers at 04:00 every day and prior to the controller defaulting I ensured that NCS also reported that the config was in sync. I have also set NCS to complete a tftp backup of the controller every night 23:00 - interestingly though I have no idea where this is stored on the NCS platform ( a VM appliance ) or what it's file name is.
Anyway my experiences where as follows:-
1. defaulted WLC and via serial CLI ended up at the configuration wizard.
2. Set the correct LAG, management IP, host name that NCS knew this controller by.
3. To test things just created a dummy WLAN ( SSID ) as I assumed this would be overwritten ( big mistake ! ).
At this point I connected the controller to the network and tried to restore the configuration from the config sync version.
First problem - you have to remember to set up the SNMP community string you were using as it is needed by the configuration sync process. After adding this to the controller I could push the configuration to the controller.
Second problem - failed to add the first WLAN from the backup as I have added the temporary dummy W LAN via the wizard and NCS reported a conflict. So had to delete WLAN ID 1 from the WLC GUI directly and then the config push no longer reported this error.
Third problem - for some reason did not add the TACACS server details - reported the error that it could not added them. I manually added these via a template via NCS and all was well.
Fourth problem - all but the first WLAN was in the disabled state - had to re-enable all of the WLANs.
Fifth problem - any default items I had disabled or removed have not been saved - therefore I have removed the public and private SNMP communities - but these were still on the WLC after the restore. I have disabled unused ports not in the LAG as they show an error in NCS - these where not disabled after the restore.
So all in all not a very satisfactory restore process from NCS to an defaulted WLC ( meant to simulate to the customer what would be needed if they had to replace a controller due to hardware failure ).
We have cisco works LMS 3.1 and the server have very problems, we need format the server and reinstall the Cisco Works, when I doin backup and restore of data LMS We lost the licenses? or when we restore the data in the server we have the same licenses? or get the new licenses to cisco?
I am facing a failed issue when restoring the WCS Database. Below is the error i get, does any one out there facing it before?

I've been setting up building and testing our new ACS 5.x boxes and I've been running into a spot of bother with the backup restore feature. This most likely due to my unfamiliarity with the tool.
As part of my testing for Backup/Restore, I first backup the data using the Removal and backup tool in Secure ACS View (found under data management. I then confirm that the new FULL backup has been populated my test repository and is available in the restore feature. (also under Data Management) My next step is to create a few test Network Device Groups, Identity groups, and users Then I go back to the restore feature select the Back up file I just created, I also check the box Skip View Database backup before Restore and hit the restore button.
The box goes through the expected steps including a reload. When it comes back up I would expect the test users, groups etc I created after the last backup to be gone as they did not exist at that time. Although I find the opposite is true. Any settings I made after the last backup are still present. I do not have incremental backups enabled.
I essentially want to test a backup of the database of users and groups/rules etc make changes and then restore that database to the previous backed up configuration.
I have a Cisco ASA 5505 as a BOVPN endpoint using certificates. The config is complete and I now need to back it up and restore to a cold standby Cisco ASA 5505 that will sit on the shelf until something goes wrong.
Problem is I cannot restore my certifcates to the standby.
I have tried the backup and restore wizard in ASDM and to be honest it didn't work.
I'm replacing an older (& failing) RVS4000 v1 with a new V2. I need to minimize downtime. Will a config backup from the old v1 restore properly to a new v2 (all have newest firmware)? There are a lot of tweaks including several VPNs and to do it all manually is not desirable.
We are trying to make a restore from the backup done on ACS version 5.1 to a new appliance running ACS5.2 Before doing it I found this note in Cisco ACS user guide:
Note: You cannot back up data from an earlier version of ACS and restore it to a later version. Backup and restore must be performed on the same version of ACS. If you need the data on a different version of the ACS, you can perform an upgrade after you restore the data. Refer to the Installation and Setup Guide for Cisco Secure Access Control System 5.1 for more information on upgrading ACS to later versions.
How should I understand it? This note has conflicting statements. We can't restore to a later version but if you need data on a different version of ACS you can perform an upgrade AFTER YOU RESTORE the data. Doesn't it mean that the restore will still work? How would I do the upgrade to version 5.2 or even version 5.3 that was announced to be released very soon? I didn't find anything on the software upgrade in ACS5.1 guide.
How can we restore ACS config from an existing backup file, in an ACS cluster deployment? is it through CLI? with"restore"or"acs restore" command? and should I restore only the ACS config or both ACS and ADE-OS config?
I have a problem with the router Linksys RV042, I made a backup of it that contains a file with the extention .exp Now we have buy a new Rv042 made by cisco and the backup file is .config the question is how I convert the .exp file to a .config file so I can Restore the backup in to the new router?
Have a 5510 in Routed mode, simple Static NAT to interface two networks (inside_1 is my private space, and outside_1 the larger intranet that hosts heavy traffic). outside_2 faces internet via pppoe just for VPN purposes.
It was operating fine for one year then one port broke (outside_2, internet), leaving no vpn. We followed RMA service replacement and the new unit came with upgraded SW (8.0.4) than the one the original config was created on (8.0.2).
To ease the replacement, I did downgrade the sw boot image. Then I did restore the config by tftp to the startup-config and then a reload. Everything seems to load fine.
Problem is that testing reveals some sort of issue: I can ping some of the intranet hosts but can't reach gateway, thus larger segment of hosts become unreachable. It seems as if the NAT mechanism can't find the next gateway where to hop. For debug practice, I've enabled all the icmp stuff so ping wasn't being blocked by the device.
Being given the fact that this config was up and running prior to the replacement, I've no reason to suspect any mysconfigured items (ie routes, NAT, access-list), but obviously I'm obfuscated and can't see what else I'm missing.
How is that possible that the PING only reaches certain hosts? Pinging to 10.15.5.90 works (Route is 0.0.0.0 0.0.0.0 to 10.15.5.126 (gw)), but pinging to the gateway itself doesn't (10.15.5.126) and even worse, hosts like 10.15.167.210 do not respond either.
while configuring my ASA 5505 I changed the IP address range of the internal network. Obviously I made an error because I cannot reach the box neither at the old nor the new address. How can I restore the interface and firewall definitions or reset the box to its initial state ? I found a doc how to reset the password, but not explaining how to restore the complete initial config.
I messed up the IOS on the flash of CISCO881-SEC-K9. On reboot it booted to ROMMON which allowed me to tftp up a working IOS c880data-universalk9-mz.151-4.M3.bin. Unfortunately somewhere in my playing around the default startup configuration factory loaded on the routerhas been erased. I can load a new a config on the device but as I'm using the router to learn its useful to have the original config load when I factory reset the device. What is the factory start up config?
so we have been using our current ASA5505 for a long time. Since it only support up to 10 VPN licenses, so we buy a new ASA5505-SEC-BUN-K9(support up to 25 users).
the old ASA are running: 8.0.3 and ASDM 6.0.3 the new ASA are running: 8.2.5 and ASDM 6.4.5
I thought it would be simple as export and import the config file, but when i tried to restore, the new one is looking for a zip file but the old one doesn;t backup file in ZIP. It looks like i need to update the ASA version or/and ASDM?
I am pretty new to this and never upgrade any of these versions since I am aware of the upgrade may mess things up. So do I need to upgrade both the ASA version and the ASDM in order to restore my config? any effect if i do the upgrade? I also read some articles, we need to upgrade on the version one by one, like 8.0 to 8.1 then 8.2?
My customer has a 4402-25-K9 and need a backup (failover) controller to avoid data transmision break when primary controller goes down.4402 are end of sale so I have a question can I use 5508 to get Controller Failover Protection with 4402 ?
I have two 5508 WLC's setup to run about 200 AP's as the moment. This is a hospital with patient care now running over wireless. I am looking for the best scenario to minimize down time. Currently both controllers are in the same mobility group and I will be setting the primary / secondary controller in the High Availability tab for each AP. Most setting are all default still.
My question: Would it better to setup the primary/secondary from the global configuration? Can I leave them in the same mobility group if I use the global configuration?
My only problem so far is having AP's on different controllers caused some response delay as clients move from one controller to the other. I need to find the best possible response time with the lowest possible fail-over time. Any recommondeations or links to a good article on this subject?
On a WLC 5508 it lists an option to specify a "Backup Port" under the physical information section on an interface. We have two central switched SSID's which are connected to an internal firewall. We are looking at installing a backup/standby firewall and running a virtual firewall between them. Each SSID would have an additional patch from the WLC to the standby firewall.
Does the backup interface port function on the WLC allow traffic to be failed over from a centrally switched SSID via backup interfaces to an alternative device? If this does work will only physical link failure to the primary firewall cause the backup port to be activated or is there configuration parameters which can be specified for load, packet loss or latency which can be used as criteria to cause the backup port to be utilized?
I have a facility, where all the access points almost 250 of them are connected to two WisM's (One in each core switch ) . They are running in 6.0.199 firmware . These two WisM's are managed by WCS , which is running 6.0.188.
As i need to add more access points and to make fully redundant , 5500 controller was ordered and it has with firmware 7.0 installed. Couple of queries related with it .
1. Can 5500 be added in the WLC group, so that existing Access Points can be configured to use primary controller as 5500 and secondary / tertiary controller as WISM ?
2. Will 5500 be able to be detected by WCS , as the version of 5500 is 7.0 and WCS version is 6.0.188 ?
3. As WCS was already deployed and live, is it possible to upgrade, if the client has support contract like SUSA ?
Since WLC5508 MGMT interface is configured a AP-Mgr at the same time, can I set a Backup Port to WLC5508 MGMT interface? Refer to WLC configuration Guide:
In the Backup Port text box, enter the number of the backup port assigned to the management interface. If the primary port for the management interface fails, the interface automatically moves to the backup port.
Note Do not define a backup port for an AP-manager interface. Port redundancy is not supported for AP-manager interfaces. If the AP-manager interface fails, all of the access points connected to the controller through that interface are evenly distributed among the other configured AP-manager interfaces
if I need to configure the backup port for MGMT interface, i need to remove the AP-manager on MGMT interface and create a network dynamic interface for AP-Manager ?
