5508 HA-SKU

[lcaruso]

Hi,

I need to determine how the HA-SKU backup controller configuration is done, how it is different from SSO-HA. I need the procedure to implement.

HA-SKU is different in that it employs two 5508's where one 5508 alone (AIR-CT5508-HA-K9) has the HA designation (can only be the backup). This allows it to receive licensing from another previously licensed 5508 (the primary). This feature was recently introduced in WLC code v7.3 or thereabouts. Appreciate your comments.

Thanks.

all you need is confiugre the redancncy mgmt ip and connect the RP ports back to back or from L2 switch. After that you set it as secondary WLC and enable sso on both WLC. The 2 wlc will reboot, when the secondary wlc with HA-SKU find the active one, it will copy the configuration and will be in standby mode once it is up.

It is pretty simple.
