Hi Sangram,
To clarify the things:
1. AP LACP is only meant to handle GRE packets.
So, it is used for distributing traffic for tunnel/d-tunnel mode ssid's.
2. In bridge mode, there is no GRE tunnel as traffic is locally bridged.
So, traffic load balancing will not occur for clients connecting to bridge mode ssid.
However, bridge mode VAP can co-exist in the same ap-group as tunnel mode VAP when AP LACP is used.
In case, your client is unable to get an IP address when connected to bridge mode ssid, we need to checkthe following:
a) Whether the ACL's for the users are getting programmed correctly.
This can be verified from ap datapath user output.
b) AP uplink capture will tell us whether DHCP packets are seen on uplink of the AP.
