thousands. Placing thousands of clients into a single large subnet or VLAN can result in
degraded performance due to factors like broadcast and multicast traffic.
To address this problem, VLAN pooling allows administrators to a deploy pool of multiple
VLANs to which clients are assigned, thereby automatically segmenting large groups of
clients into multiple smaller subgroups, even when connected to the same SSID. As the
client device joins the WLAN, the VLAN is assigned to one of the VLANs in the pool
based on a hash of the client's MAC address. While you can also achieve the same
results using Dynamic VLAN, with VLANs assigned by a RADIUS server (see
How Dynamic
VLAN Works on page 175), the VLAN pooling feature allows distribution of clients into
multiple VLANs without the need for a RADIUS server.
To create a VLAN pool:
1. Go to Configure > WLANs , and locate the VLAN Pooling section.
2. Click Create New to create a new VLAN pool.
3. Enter a Name , and optionally a Description for this VLAN pool.
4. In VLANs, enter the VLAN IDs to be assigned to this pool. VLAN IDs can be separated
by hyphens, commas, or a combination (e.g., 7-10, 13, 17, 20-28).
5. Click OK to save the VLAN pool. Each VLAN pool can contain up to 16 VLANs, and
a maximum of 64 VLAN pools can be created. Each WLAN can be configured with
a single VLAN pool.
