VLAN Configuration

VLAN configuration is required for networks with more devices and broadcast traffic on a WLAN SSID or wired

profile. Based on the network type and its requirements, you can configure the VLANs for a WLAN SSID or wired

port profile.

For more information on VLANconfiguration for a WLANSSID and wired port profile, see Configuring VLAN Settings

for a WLAN SSID Profile on page 89 and Configuring VLAN for a Wired Profile on page 103.

VLAN Pooling

In a single OAW-IAP cluster, a large number of clients can be assigned to the same VLAN. Using the same VLAN

for multiple clients can lead to a high level of broadcasts in the same subnet. To manage the broadcast traffic, you

can partition the network into different subnets and use L3-mobility between those subnets when clients roam.

However, if a large number of clients need to be in the same subnet, you can configure VLAN pooling, in which each

client is randomly assigned a VLAN from a pool of VLANs on the same SSID. Thus, VLAN pooling allows automatic

partitioning of a single broadcast domain of clients into multiple VLANs.

Uplink VLAN Monitoring and Detection on Upstream Devices

If a client connects to an SSID or wired interface with a VLAN that is not allowed on the upstream device, the client

will not be assigned an IP address and thus cannot connect to the Internet. When a client connects to an SSID or a

wired interface with VLANthat is not allowed on the upstream device, the AOS-W Instant UI now displays the

following alert message:

Figure 30 Uplink VLAN Detection

To resolve this issue, ensure that there is no mismatch in the VLAN configuration.
