5508 to join with 2 Wism's as backup

Answered Question
Jun 21st, 2012

Dear Folks,

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 ?

Appreciate your kind help and support .

Regards,

SID

I have this problem too.

As for WCS, you just should upgrade and not do a reinstall. An upgrade will keep your current WCS data. The release notes will explain how to upgrade WCS to that specific version.

Correct... You can make the primary boot the 6.0.119 and just leave the 7.0 there as a backup. As far as the WCS, as long as you have a service contract you can upgrade the WCS. The license will stay the same as long as the hostname doesn't change.

You need to keep the code the same on all controllers in which your APs may join. Also it's a rule of thumb that the WCS, NCS, and MSE be on the same or higher code version than the WLC.

You need to downgrade the 5508 to the version your WiSMs are running or else you will need to upgrade your WiSMs and WCS to 7.0.x. If you go that route, 7.0.235.9 is the code you need to go with on the WLC's.

Thanks Scott for your valuable reply .

Two more queries please,

1. I saw in 5500 controller with two images installed by default,  one is 7.0 and other one is backup recovery image , which is 6.0.199 , can we boot the controller with that image , or we should directly downgrade it from 7.0 to 6.0.199

2. With an existing service contract, is it possible to reinstall WCS with an upgraded version, as i understand , license would be tagged with the Computer's hostname , right
