VLAN Pooling is now a supported on CnPilot E-series devices.
Note: This feature is available from 3.2-r1 release build.
Prerequisites for VLAN Pooling
A VLAN should be present on the AP to be able to add it to the VLAN pool and AAA server should able to provide VLAN-Pool name in Cambium vlan pool radius attribute.
Restrictions for VLAN Pooling
The number of VLAN Pools on the AP should not exceed value of 16.
The number of VLANs mapped to a VLAN pool is not limited. But it is the responsibility of the administrator to configure feasible number of VLANs in a VLAN pool.
For expected behaviour of the VLAN pooling, the VLANs mapped in the pool must be present on the AP.
Information About VLAN Pooling
Whenever a wireless client connects to a wireless network (WLAN), the client is placed in a VLAN that is associated with the WLAN. In a large venue such as an auditorium, a stadium, or a conference room, university where there are numerous wireless clients, having only a single WLAN to accommodate many clients might be a challenge. The VLAN pooling feature uses a single WLAN that can support multiple VLANs. The clients can get assigned to one of the configured VLANs. This feature maps a WLAN to a single VLAN or multiple VLANs using the VLAN pool. When a wireless client associates to the WLAN, the VLAN is derived using round-robin algorithm. A VLAN is assigned to the client and the client gets the IP address from the assigned VLAN.
Note: In 802.11R roaming and OKC, when client roams from one AP to other AP, it maintain same IP address and it provide seamless roaming in VLAN Pooling also.

Add Cambium vendor specific attribute of Vlan pool name in users file in freeradius:
john Cleartext-Password := "sm!th"
Tunnel-Type = VLAN,
Tunnel-Medium-Type = IEEE-802,
Tunnel-Private-Group-Id = 10
Cambium-Vlan-Pool-Id = "pool1"
