What are the advantages of local forwarding?

 In local forwarding mode, APs directly forward client packets instead of transferring all packets to the AC. This reduces the AC's load. You can specify a VLAN or a VLAN range to enable APs to forward client data traffic from the specified VLANs.

For example, in a branch+headquarters network where the AC is deployed at the headquarters and APs are deployed in branches, you can configure local forwarding as a best practice.
