specifying primary/secondary controllers on APs

andrewswanson · ‎06-17-2008

hello

we currently have 1 4404 controller at site A with around 70 APs spread over a number of sites. we're planning to expand the number of APs and intoduce some reiliance to the WLAN by installing a wism in a 6500 at site B to the 4400.the plan is:-

the 4404 will control the APs at site A.

the wism will control the APs at site B and other satellite sites.

the APs currently get the 4404s IP address via option 43 from dhcp. to get APs to associate with a particular controller can i use option 43 to specify primary/secondary controllers or do i have to 'hard code' this info via the Primary/Secondary Controller Name option (if this is the case can you do this from WCS in V5 or can it only be done from the cli as in v4.2)

thanks

andy

Hi,

I would use the Primary/Secondary option... option 43 will not help your AP decide which one should be the primary, this has to be an AP local information... you can easily do this from WCS, just create an AP template with the secondary controller option clicked and push it down to the APs you need...

BTW, both controllers would preferably be in the same mobility group and know about each other...

hope it helps
