VLAN pooling is commonly used in high density deployments where you have lot of clients. Placing thousands of clients into a single large subnet or VLAN can result in degraded performance due to factors like broadcast and multicast traffic. VLAN pooling allows administrators to configure a pool of multiple VLANs and each client is assigned a VLAN from the pool on the same SSID. Thus, VLAN pooling automatically partitions large groups of clients into multiple smaller subgroups, even when connected to the same SSID.
