OS version used is 8.3x in all the controllers

Try to use "Preserve Client VLAN" in the Virtual AP profile.  If the two controllers share the same layer 2 network for client VLANs, the second controller will attempt to see if the Client's mac address is in the ARP table and on what VLAN.  If the client's mac address exists, it will attempt to put that device into the same VLAN.

Re: Inter controller seamless roaming(L2), options

Do you have an MM?  If not, you cannot do a cluster configuration.

Re: Inter controller seamless roaming(L2), options

If you don't have an MM, you cannot form a cluster.

Are the clients using the same layer 2 network on both controllers for that SSID?

Are you using VLAN pooling?

What authentication and encryption are you using?
