What is step by step procedure for configuring aruba wireless controller , how to add multiple ssid on it , one voice ssid, one data ,configure rules?

First setup a L3 interface on the controller, that is the controller-ip and assign a respective gateway and have it plugged into the network.

Upgrade the controller to the lastest AOS version considering the kind of AP's that would be terminating on the controller.

Create an ap-group --> map a Virtual AP --> map the respective aaa-profile and ssid-profile

we can add multiple SSID's as mentioned above to the respective group by configuring the 

respective VAP's and aaa-profiles

Create a PSK based SSID for voice and create a voice-role (with acl's to prioritize the VoIP traffic) and map it to the initial role of the aaa-profile and map the aaa-profile and ssid-profile to the respective VAP.

Following are the ACL's:-

SIP-ACL

NOE-ACL

SVP-ACL

VOCERA-ACL

SKINNY-ACL

H-ACL

DHCP-ACL

TFTP-ACL

DNS-ACL

ICMP-ACL

Likewise, we can configure a SSID for employees either as a PSK or a Dot1X based on the requirement

and map the appropriate role with any any any permit acl in it

For the rules, we can configure it through the command:-

ip access-list session <session-name>

any any any permit

user-role <role-name>

access-list session <session-name>
