Hi,
today we have two WLC 8540 in HA topology, with 8.2 software, we cannot upgrade the software because we have old APs (1142,2600,3600 etc,) as long as new APs (3800/3700). second, we consider buying a new 9100 AP series, but those APs supported by the 8540 from version 8.9.
we decided to install new WLC8540 - stand alone, and we will migrate old APs to the new 8540, that's will allow us to upgrade the 8540 HA.
i thought to install the new 8540 as stand-alone and to stretch the L2 between the to WLC.
the L3/GW of the clients reside on the L3 switch the 8540 connected to.
which installation we can deploy? i have no previous knowledge, so i will glad for a suggestion whats the best deployment?
thanks,
